Practice Notes
Preparing a brigade legal section (BLS) for a combat training center (CTC) rotation1is a lot like preparing yourself, physically and mentally, for
the Army Fitness Test (AFT). Like the AFT tests physical preparedness for battle, a CTC rotation tests how ready
a brigade, and thus a BLS, is for ground combat.2Just as you would not wait until the week before the AFT to begin exercising your
muscles, a BLS should start exercising its tactical systems and processes at least six months in
advance of the rotation.3Furthermore, while
agonizing over any performance event can be detrimental to results, a little bit of eustress can go a long way
toward maximizing potential.4Finally, just as
reaching a personal best in the AFT demands readiness in five distinct events,5achieving success during a CTC rotation requires the BLS to
prepare along five lines of effort (LOEs): (1) manpower utilization within the brigade combat team (BCT)
headquarters (HQ) command nodes; (2) paralegal employment apart from BCT HQ; (3) an in-depth communications
plan; (4) comprehensive fighting products, including a robust legal running estimate; and (5) effective training
of the force on legally related topics.
This article, written from the perspective of a senior operational-law observer–coach/trainer (OC/T), discusses
each of these points in turn. Nonetheless, it is not intended to be the only resource on the subject. Read this
article in conjunction with two other published commentaries on preparing a BLS for a CTC rotation. The first,
Building National Security Law Readiness Through Combat Training Center Rotations, by Lieutenant
Colonels (LTCs) Tim Davis and Jason Young, appears in issue 2, 2022, of The Army Lawyer.6LTCs Davis and Young explain how CTCs
function, how they prepare BCTs for large-scale combat operations (LSCO) and multi-domain operations (MDO), and
what to do in the lead-up to a CTC rotation.7The second, Preparing for Success at the Combined Training Centers: an OC/T
Perspective, was published in volume 23-3 of The National SecurityLaw Quarterly.8This article, penned in 2023 by Major (MAJ)
Tyler Gattermeyer and the senior judge advocate (JA) OC/Ts of the three “dirt” CTCs, LTCs Andrew Browell,
Timothy Davis, and Jason Young, offers seven keys for success at a CTC rotation.9
The article that follows, along with its appendix, Top 5 Considerations for OPLAW in LSCO, is a guide
intended for the BCT brigade judge advocate (BJA). It builds on the sage advice of the two articles mentioned
above while discussing five practical LOEs on which you—as the BJA—should focus your efforts.
LOE 1: Manpower Utilization Within the BCT HQ
Like a baseball manager filling out a line-up card for an upcoming game, you need to know who exactly is going
to be on your team so you can put them in the right spot. But before you can assign players to the batting
order, you need to know how the game is structured.
First, to fill out the roster for the BLS, you must identify what the BCT command nodes will look like. In
preparation for LSCO, recent CTC rotations have featured small, mobile command posts (CPs) which emphasize speed
and survivability, sometimes at the expense of capability.10Brigades typically have a tactical operations center (TOC) or current-operations
(CUOPS) node, which controls the “current fight,” and a future-operations (FUOPS) node, which plans for
everything from the deliberate prosecution of targets to detainee operations. These cells are often styled as
the main command post (MCP) and rear command post (RCP), respectively,11and are often placed “one terrain feature” (at least several
hundred meters) away from each other to enhance survivability.12
Furthermore, there often will be a tactical command post (TAC) that “pushes out” from the MCP with perhaps only
a vehicle or two, carrying the BCT commander, the S2 intelligence officer, and the S3 operations officer, ready
to control the fight in certain situations, such as when the MCP displaces, or “jumps,” from one location to
another. Yet another node may exist “over the horizon” at a mission-support site (MSS).13Speak with the S3 well before the rotation to find out how
the BCT intends to set up its physical footprint.14
Once you have identified how the BCT will array its CPs, start planning how to staff them. The gold standard is
for the BLS to include you, of course, plus two company-grade attorneys and the senior paralegal noncommissioned
officer (NCO).15Presumably, one of the junior
attorneys will be the administrative/operational-law (ADLAW/OPLAW) attorney who serves the BCT.16You may need to request that the staff
judge advocate (SJA) augment the team with an additional company-grade attorney, or perhaps two, if the BCT does
not have an organic ADLAW/OPLAW attorney.17
The BCT senior paralegal NCO should be well-versed in operational law issues, including the law of armed
conflict (LOAC) and rules of engagement (ROE). Because the senior paralegal NCO will spend most of the time in
one of the BCT HQ nodes, that individual will need to be able to spot issues pertaining to the fires and
protection warfighting functions (WfFs) and relay those issues to the servicing attorney, should advice be
needed. Furthermore, prior to the rotation, the senior paralegal NCO will play a critical role in training
paralegals from subordinate battalions (BNs) in operational law and the conduct of administrative
investigations, as discussed in LOE 2 below. Consider sending the senior paralegal NCO to attend the Battle
Staff NCO course,18the Paralegal Employment
in LSCO (PELSCO) course managed by the Center for Law and Military Operations (CLAMO),19and perhaps the National Security and Law of Armed Conflict
(NSLOAC) course at The Judge Advocate General’s Legal Center and School, well in advance of the BCT’s validation
exercise (VALEX).20
Once you identify the players on your BLS starting roster, consider how to array them among the BCT HQ command
nodes. Assuming two other attorneys will attend, plus a senior paralegal NCO, the best course of action is for
two attorneys to staff the MCP in twelve-hour shifts, while another attorney and the senior paralegal NCO cover
the RCP. Except for “fight nights,” fewer legal issues typically arise from the MCP than the RCP, so place the
two most junior attorneys there. The more experienced among those two should cover the night shift, as the Army
often conducts more combat operations under the cover of darkness than in broad daylight.21
Typically, as the BJA, you will add the most value by serving in the RCP, advising the targeting cell in
planning deliberate targets, assisting the protection and fires cells with ROE-change requests,22and participating in the Military
Decision-Making Process (MDMP) as a member of the BCT battle staff.23You are the best-positioned officer to help the staff
understand the commander’s level of risk tolerance with regard to collateral damage during deliberate
targeting.24That said, under certain
circumstances, it may be better for you to man the MCP personally. For example, if you are new to the team and
the BCT commander plans to spend significant time in the MCP, your presence there will give you a vital
opportunity to build that relationship in stressful situations.
The senior paralegal NCO can assist the attorney in the RCP by maintaining communications with paralegals at
subordinate BNs. Furthermore, the senior paralegal NCO can cover battle-rhythm events the RCP attorney misses,25such as when the attorney is called away
to meet with a representative of the International Committee of the Red Cross or visit the U.S. consulate in the
host-nation capital with members of the civil affairs team.26
Just like with training for an AFT, success at a CTC will come only by preparing well in advance. Whether it
be positioning people in the BLS in the appropriate spots, preparing paralegals to maximize value to their
BNs, planning for breakdowns in communications, developing effective fighting products, or training the
force correctly, you will get out of the CTC experience what you put into it.
However, incorporating three highly capable attorneys into the BLS will be of only limited value if they are not
properly integrated with the staff. Building relationships with members of the fires and protection WfFs is
especially important.27In the RCP, staff
integration starts with getting to know the officer who will be running the MDMP for the BCT; this is often the
brigade executive officer (XO) or S3 operations officer, but it is sometimes a staff captain.28Help this officer (often known as the
“plans chief”) understand the contributions the BLS can make to the MDMP.29Early integration with the planning staff will help you “bake
in” legal considerations to the planning process.30
Although the RCP legal advisor is often positioned to provide more legal advice to the BCT, it is still
essential for the BCT to have an attorney present in the MCP. Expect this attorney to be the only person in the
BCT who is actively monitoring the fight to confirm that the actions of subordinate BNs comply with the LOAC and
ROE. For example, if a subordinate BN intended unilaterally to destroy a bridge, that action might not be
permissible under the ROE. The legal representative in the MCP is best poised to catch that issue and point out
to the BCT staff any disconnect with the ROE, thereby mitigating risk to the BCT commander and the brigade’s
mission.
Despite the importance of the MCP legal advisor, the current era of ever-shrinking CPs may limit the ability to
maintain a dedicated legal presence there. One potential way to maintain a consistent presence in the MCP is by
taking on a collateral duty within the cell. For example, during a recent rotation, a BLS found success in
maintaining its position within a small MCP by also managing the digital and analog common operating picture
(COP) for the BCT. The BLS was already planning to have a twenty-four-hour presence in the MCP, so managing the
COP did not pose an additional burden. In fact, performing this collateral duty helped MCP legal personnel stay
alert and actively track the battle, thereby increasing their effectiveness in advising BCT staff.31
What should you do, however, if you cannot meet the gold standard of three attorneys and a senior paralegal
NCO?32Even when a BCT is resourced with only
one attorney in addition to the BJA, success remains possible. Consider sending the junior attorney to cover the
night shift in the MCP while the senior paralegal NCO takes the day shift. This arrangement would require the
senior paralegal NCO to listen closely for legally related issues and engage you in the RCP when legal advice
becomes necessary.
There may come a time when, despite advocating for a legal presence and successfully integrating with the staff
during pre-rotational exercises,33MCP
configurations exclude a legal advisor. In such a case, you would need to work doubly hard in advance of the
rotation to train the battle staff on the LOAC and ROE and how to spot other legally significant events (LSEs)
that may require investigation, such as fratricide and civilian casualties.34
LOE 2: Paralegal Employment Apart from the BCT HQ
Paralegal employment in LSCO, known as PELSCO, is about maximizing the contributions of paralegal specialists in
a combat environment, where BN commanders and their staffs face existential threats daily. Although these senior
officers are closely familiar with how junior-enlisted paralegals support the BN’s mission in garrison—primarily
in military justice—senior officers may not be as familiar with BN paralegals’ capabilities in a LSCO setting,
where the LOAC, ROE, and administrative investigations dominate the legal space. To best empower paralegals in
this arena, CLAMO has identified PELSCO as an area of emphasis, and it offers a course dedicated entirely to
it.35Several articles addressing the topic
have also been published recently in the National Security Law Quarterly.36
PELSCO shifts the role of the 27D paralegal specialist beyond its roots as a legal clerk37to one of an educator. In many BNs, the paralegal
enters the investigation process only once it has been approved and the commander, with an attorney’s advice,
has already decided how to dispose of the misconduct. In LSCO, however, junior paralegals will need to get
involved with administrative investigations under AR 15-638far left of boom, i.e., as soon as the investigating officer (IO) has been
appointed.39

Expect a higher threshold in LSCO than in other contexts for triggering investigations of certain types of
incidents. For example, in garrison and even during combat deployments in low-intensity conflict, every death of
a Service member must be investigated.40Such
stringent investigatory requirements may not endure in LSCO, given the expected high fatality rates in such a
conflict.41Nevertheless, certain events, even
in LSCO, will require an administrative investigation, no matter how high-intensity the conflict.
For example, a civilian-casualty (CIV-CAS) or fratricide incident would likely require an investigation. For
practical reasons, these investigations must be initiated and completed quickly—the appointing authority will
want lessons learned to prevent such incidents in the future, and at a CTC, the rotation lasts only a couple of
weeks, so time is of the essence. Furthermore, BCTs sometimes experience real-world LSEs, such as when an entire
pallet of frozen food is left to melt on a sunny loading dock in the staging area. For these reasons, you must
be poised to support investigations, both scenario-driven and real-world, quickly and thoroughly.
Nevertheless, the systems and processes that work for the BLS to support investigations in garrison often turn
moribund in “the box” (the combat training area at a CTC). For example, attorneys likely will not be able to
track down IOs to in-brief them and hand them the IO toolkit. Attorneys at the BLS often fail to appreciate how
immobile they will be, unable to leave the BCT HQ tents.42The BLS may not have its own vehicle, or if it does, there may be a force-protection
requirement that each vehicle leaving the BCT HQ footprint be escorted.43Additionally, attorneys may simply lack the time to conduct
battlefield circulation, and communications to reach IOs who are not located at the BCT main may be
unreliable.44
For these reasons, it is essential to prepare every paralegal to support administrative investigations. As a
starting point, each para-legal should carry into the box a hard-copy IO toolkit with multiple copies of “fill
in the blank” appointment orders, sworn-statement forms, rights-advisement forms, and even blank paper for IOs
to use.45Beyond carrying the forms, however,
paralegals should be prepared to in-brief IOs, walk them through the investigation as needed, and examine the
finished product once complete. This level of support constitutes administrative, not legal, advice, and thus is
appropriate for a paralegal to offer.46Nonetheless, such assistance is beyond what most paralegals do daily in garrison.
Accordingly, start preparing 27Ds early by giving them opportunities at home station to conduct in-briefings and
advise IOs well in advance of the CTC rotation.

Another way BN paralegals can add value to their units’ missions as educators is by training their formations on
the LOAC prior to the VALEX. Not only is such training a practical necessity for Soldiers heading into a CTC
rotation, it is required for Soldiers in modified table of organization and equipment (MTOE) units under Army
Regulation 350-1.47With the relevant
commander’s consent, you may employ a junior-enlisted paralegal to assist you, the ADLAW/OPLAW attorney, or the
paralegal NCO in delivering LOAC training at the Soldier level.48The three of you would have to work hard to ensure each paralegal is “trained to
train”; however, like with support to investigations, getting paralegals ready to actively assist in training
the LOAC can begin even a year in advance of the rotation. The benefit to involving BN paralegals in conducting
LOAC training is the relationship of trust they may build with their respective BN S3 sections—a relationship
which, once cemented, may provide the paralegals access to decision-makers as the BN transitions to combat
operations.
Paralegals can also provide LOAC education within the BN CP itself. In the same way that in-briefing IOs and
checking their work for formatting and completeness are perfectly acceptable tasks for a paralegal, so is
talking through LOAC issues with the BN commander and staff—short of providing legal advice, of course. Some
issues may be simple, such as fielding a question on the approval authority to crater a main supply route. Other
questions may be more complex, such as those that relate to kinetic fires in a populated area. Regardless, the
BN paralegal should always be able to point commanders and staff to the proper authority, whether in law,
regulation, or policy.
Paralegals may act as sounding boards for commanders and staff. Rather than giving a definitive opinion on a
subject, which would constitute legal advice, they might shape the conversation by asking questions. For
instance, if a maneuver BN were considering mortar fires into a village, a 27D might ask, “Have you considered
the principles of distinction and proportionality?” The paralegal could then explain what those targeting
principles comprise. “Legal advice” is not explicitly defined in Army regulation, so it is difficult to
determine its exact boundaries.49Nonetheless,
asking pointed questions and engaging in discussion about the LOAC is within the purview of all
Soldiers, not just attorneys,50so it is
completely appropriate for a paralegal to have these conversations with BN leaders, as long as all concerned
understand the paralegal is not giving legal advice.51
As discussed above, properly educated junior paralegal specialists can add significant value to a BN in aspects
that matter to LSCO. Therefore, the BN paralegal must maintain access to the BN CP. Battalion CPs across the
Army continue to grow smaller, more mobile, and, thus, more survivable.52As a result, a dedicated paralegal seat in a BN CP is rare.
To mitigate the effects of this evolution, work with the senior paralegal NCO to prepare, well in advance of the
VALEX, to ensure a paralegal presence in each BN CP. A variety of options exist to help paralegals maintain
placement in or near the BN CP, all with two goals in mind: (1) maintain access to information that will allow
the paralegal to support BN operations (as discussed above), and (2) preserve the ability to communicate with
BLS personnel at the BCT HQ cells.
One course of action is for the paralegal to get trained as a radio telephone operator (RTO) and then apply that
training as a dedicated RTO within the BN CP. That way, the paralegal will maintain access to both information
and communications.53Another approach is for
the paralegal to get assigned as the driver for the BN commander or command sergeant major. The paralegal would
then have access to relevant information as well as communications equipment inside the vehicle.
For maneuver BNs, a recent rotation at the Joint Readiness Training Center demonstrated the effectiveness of
proactive BJA involvement. The BJA coordinated with the BN S1 officer-in-charge (OIC) to align paralegal
support—the S1 OIC could integrate the paralegal into BN operations, and the paralegal was permitted twice-daily
access to the BN CP to gain situational awareness of the battle and report digitally to the BLS.54The S1 OIC assigned the paralegal to
conduct perimeter security around the BN CP for most of each day, and the paralegal gained twice-daily access to
information and communications. In this way, the BN paralegal identified and relayed to the BLS two LSEs that
had not reached the BCT HQ through operational channels.55
One creative option is for a paralegal at a brigade support battalion (BSB) to nest with the Role 1 medical
station or the S1 personnel section.56Assigning the paralegal to work on casualty tracking or reconstitution packets would
allow swift access to information on any mass-casualty event, which could perhaps indicate a fratricide.
The discussion above assumes each BN has an organic paralegal who will actually participate in the CTC rotation.
Should that assumption be incorrect, examine the impact on each BN of not having paralegal support. Consider
asking the SJA to attach a non-organic paralegal specialist to the BCT for the rotation.57Conversely, think long and hard about where and how to assume
risk by leaving one or more BNs without legal support.

with them, SPC Cosmas assisted with area security during a lull in legal actions. (Photo courtesy of author)
LOE 3: Communications
If an attorney sends an e-mail in the forest, and there is no one with a suitable device to read it, is it
still communication?
Although this question sounds like a glib take on a classic thought experiment,58it underscores the essence of communication: There must be a
sender, a recipient, a message, and a means of transmitting that message.59It is on that last element, the means of transmission, that
BLS often stumble.
The articles mentioned above by LTCs Davis and Young and by MAJ Gattermeyer et al. describe the value of having
a communications plan at the BLS level.60Specifically, the BLS plan must spell out the primary, alternate, contingency, and
emergency (PACE) ways of communicating, with the expectation that periods of degraded communications are the
norm at CTC rotations.61
While degraded comms are sometimes caused by enemy action, they are often due simply to the friction of bringing
a large volume of high-tech systems into an austere environment. Regardless, as with the other points of CTC
preparation, it is essential for you and the senior paralegal NCO to start planning well in advance for how to
establish and execute an effective PACE plan.62
Once you have determined how legal support to the BCT HQ and BN command cells will be arrayed and who will staff
each (discussed in LOEs 1 and 2 above), you are ready to start planning how BLS members will communicate with
each other. First, talk with the brigade S6 and S3 to learn which communications platforms will predominate
throughout the BCT.63Then, identify which
platforms the attorneys and paralegals will have access to at each node; this includes not only devices but
networks as well.64
For example, if you intend to bring laptop computers to operate on a tactical secure Internet protocol router
network (TAC SIPRNet) in the MCP, confirm with the BCT S6 signal section you will have access to a SIPRNet “red
line.” Assuming you have access to both a TAC SIPRNet machine and network in the MCP, verify you will have the
same access in the RCP, and ensure the BN paralegals have access to that hardware and network in their
respective CPs as well.
If all BLS personnel have access, even borrowed access, to TAC SIPRNet, you can include it on the BLS PACE plan.
If not, however, you may still choose to bring your TAC SIPRNet computer to communicate with higher headquarters
(HHQ), assuming that mode of communication in on the HHQ PACE plan. But, of course, you will need to find other
comms platforms to use in the BLS PACE plan.
Within the BCT, you may need to field calls from BN commanders and staff and even leaders at the company level.
Before entering the box, ensure these leaders know how to reach the BLS. When briefing BN-and company-level
leaders on the ROE, consider informing them of your PACE plan and of any brigade-level requirements to report
LSEs.65
Furthermore, as discussed above with LOE 2, consider delegating IO in-briefings and investigation formatting
advice to the BN paralegals. Still, IOs may need to reach an attorney at BCT HQ for legal counsel. Therefore,
all BN paralegals should know the BLS PACE plan as well as you do, to ensure they can put someone in touch with
you at any time.
The PACE plan is just one element of an effective comms plan. In addition to PACE, make sure all members of the
BLS are trained on all platforms. For example, if WebMC—the laptop-based way to access the Joint Battle
Command–Platform (JBC-P)—is on the PACE plan, even the most junior paralegal must know how to use it.
Furthermore, establish (and enforce) a daily legal sync to drive communications. Sometimes the junior paralegals
may not have anything to say, but they still need to hear from you and the senior paralegal NCO frequently.
Finally, make sure the BN paralegals know it is their responsibility to work the PACE plan proactively. If the
primary comms platform is unavailable and the alternate method is causing trouble, the paralegal needs to (1)
get help from another Soldier who knows how to use the comms platform, (2) find a Soldier who can relay a
message to you, or (3) proceed to the contingency or emergency forms of communication. The BN paralegals must
understand how often they are expected to check in and that the comms exchange is not complete until they
receive an acknowledgment.66
LOE 4: Effective Fighting Products
A fighting product is simply “a tool that aids in the accomplishment of a task.”67 Such a tool may be graphical or documentary.68 All WfFs create and use fighting
products, which include templates, matrices, map overlays, prioritized lists, and more.69
For any staff section or WfF, the heart of the fighting products is the running estimate. Per Army doctrine, “A
running estimate is the continuous assessment of the current situation used to determine if the current
operation is proceeding according to the commander’s intent and if planned future operations are supportable.”70Each section’s running estimate includes
facts, assumptions, an assessment of current operations, and recommendations for the future, among other
elements.71Running estimates, if kept up to
date and accurate, enable the commander and staff to understand the operating environment and, thus, make
effective decisions.72
Leverage the legal running estimate to analyze BLS operations and how effectively they are supporting other
staff sections and the BCT as a whole.73The
legal running estimate may also help with analyzing the level of legal risk the commander is assuming, along
with facts, assumptions, and issues involved with legal support.74The commander may never ask to see the legal running estimate, but the analysis that
goes into building and maintaining it is essential to your ability to contribute meaningfully to the operations
process.75
The legal running estimate is especially helpful during planning. Entering the MDMP with a draft legal running
estimate will enable meaningful contributions to the planning process. As soon as the BCT receives a warning
order from HHQ, start updating the legal running estimate to reflect the new mission.76Then, with each step of the MDMP, update the running estimate
based on the new legally related dimensions of the operating environment.77The running estimate should go beyond the “what,” informing
the “so what,” and shaping the “therefore.”
Field Manual 3-84, Legal Support to Operations, provides a template of a legal running estimate.78This example incorporates trackers for
investigations, BCT orders, and other legally related data.79Many BLS at recent CTC rotations have chosen to produce trackers and graphic
organizers that are distinct from the basic legal running estimate. BLS fighting products typically include an
LSE tracker, an ROE-change tracker, a BCT-orders tracker, and an authorities matrix,80among others, that may be helpful to you and the greater
staff.81Regardless of the format, though,
doctrinally, these trackers all nest within the legal running estimate.82
It is never too early to start developing a legal running estimate. In fact, Army doctrine encourages keeping a
running estimate updated even during garrison operations.83At the latest, create it in the lead-up to the VALEX. The VALEX is the opportunity to
confirm the legal running estimate is in the right format while you still have time to make any necessary
improvements before the CTC rotation, and of course, before a real-world mission.84
Incorporating the running estimate into a broader BLS standard operating procedure (SOP) has worked for some
legal sections.85As MAJ Gattermeyer et al.
point out, such an SOP could include not only the running estimate and any attached trackers or matrices, but
also packing lists, shift-change briefing agendas, BLS-specific information requirements, wake-up criteria, and
doctrinal references.86Get junior attorneys
and paralegals involved in the run-up to the rotation by delegating the responsibility for developing most or
all of these products.
Although most BLS are accustomed to working primarily in the digital space, it is essential to carry the SOP,
running estimate, and associated trackers in analog format as well. For one reason, computers break, networks
fail, and the electricity goes out. As LTCs Davis and Young point out, “In a degraded information environment
due to jamming, lack of power, cyberattack, or other enemy means, JALS personnel will learn the importance of
planning for such situations.”87In such an
environment, analog fighting products will become essential for you and the BLS to maintain “shared
understanding.”88Additionally, consider
posting hard copies of the ROE authorities matrix and key trackers in conspicuous places in command nodes to
help other staff sections maintain awareness of legal issues when the BLS is busy or elsewhere.
Leverage the experience of the BLS of any sister BCTs that have gone through a CTC rotation recently.89Speak with your counterparts to find out
which fighting products worked well and which needed refinement. Senior paralegal NCOs ought to do the same with
their counterparts. In addition to providing advice, the sister BLS may be able to furnish valuable templates
that could subtract hours from the time required to produce the legal running estimate and BLS SOP.
On the subject of documents, you are responsible for producing the legal-support tab, commonly known as the
“legal annex.” This document is appended to the BCT operations order, Annex F (Sustainment), Appendix 2
(Personnel Service Support), Tab C (Legal Support).90Although not a fighting product, per se, this supplement explains to the BCT
how the BLS will provide legal support to commanders, staff, and warfighters alike.91Delegate the first draft of the legal-support tab, as well as
the authorities matrix and other products, to an NCO or junior attorney as a valuable developmental experience.
LOE 5: Training the Force
In the half-century since the end of the Vietnam War and the initiation of the Department of Defense Law of War
Program in the mid-1970s, the legal advisor in the brigade CP has gone from being non-existent to being as
normal as green spots on camouflage.92In
fact, the United States recognizes as customary international law the requirement that a legal advisor be made
available to every operational commander.93During the two decades of the Global War on Terrorism (GWOT), it was typical for a
commander above the BN level to have a JA present, and even concurring, every time the commander authorized a
lethal kinetic strike.94The constant presence
of the CP legal advisor was due to the demand for near-perfect decisions in counterinsurgency or
counterterrorism environments95and the fact
that our enemies in the GWOT usually were unable to target our CPs, thereby allowing for spacious working
environments.96
Such luxuries will not exist in LSCO.97As
noted above in LOE 1, there may be times when space limitations keep legal advisors out of the MCP. Nonetheless,
a BLS at a recent CTC facing this reality still found success in setting the table for principled, LOAC-driven
decisions on the part of commanders and staff.
Proximity alone does not equal influence, as MAJ Dane Rockow and CPT Karolyn Kerwin have pointed out.98And that is a good thing, because in LSCO,
it is inevitable that commanders and staff members at the brigade level will need to apply the LOAC on their own
without steady legal advice to guide them.99Preparing the BCT for LSCO, therefore, requires training the entire team on the LOAC
and the ROE before entering the fight.100The BLS can multiply itself and extend its influence exponentially by equipping
commanders and staff members within the BCT with practical knowledge of the LOAC and ROE they can apply
without legal counsel in real time.101
In preparing for decisive action, distinguish between two training audiences: trigger-pullers and shot-callers.
The LOAC is for everyone, including trigger-pullers; thus, every Soldier in an MTOE unit needs to be trained on
it,102and certainly before the VALEX and
CTC rotation. The principles of LOAC are relatively static and set the foundational ground rules for the ethical
application of lethal force in combat.103
Network early and often with the BCT S3 section and the corresponding S3 sections of the subordinate BNs. Get on
their training calendars months ahead of the VALEX to reach the maximum audience with the LOAC message. As
discussed above with LOE 2, you and the senior paralegal NCO should empower the BN paralegals with the LOAC
expertise required to deliver these briefings at the BN and company level effectively.
That said, LOAC training will have its greatest effect when the BCT commander emphasizes its importance and uses
the training to convey command philosophy and tolerance for risk on the battlefield to the BCT staff and
subordinate commanders.104The Judge
Advocates General of the Army in recent years have emphasized the importance of vignette-based training, driven
by the commander, to help subordinates think through how the LOAC applies in a variety of settings.105Such training is important not only to
help these commanders and staff members understand the BCT commander’s appetite for risk, but also to give them
the confidence to shoot when the situation requires it.106
The full ROE, on the other hand, need to be briefed only to the shot-callers, i.e., the decision-makers, in
LSCO. The ROE contextualize the LOAC, turning static principles into dynamic, policy-driven rules for the
application of force.107In LSCO, ROE inform
commanders and staff members who (what level of command) may approve the use of which weapon
systems and the engagement of what kinds of targets.
Although the ROE are rooted in the LOAC, they constitute policy, so you will not be able to train the
shot-callers on the ROE until you receive them from HHQ.108For a CTC rotation, that opportunity likely will not come until you have arrived at
the CTC. Nonetheless, begin planning as early as you can to identify a time to brief the shot-callers on the ROE
before entering “the box,” i.e., the maneuver training area. The target audience should include BCT and BN
commanders and staff members, as well as company commanders and first sergeants.
To bring the discussion full circle with LOE 1, do not neglect to train your own “force,” i.e., the BLS, on
finer points of the LOAC that will apply during the CTC rotation. By serving as the BCT’s subject-matter experts
on the LOAC, attorneys and paralegals will foster a specialized skillset that will help them integrate into the
staff. Begin by opening up Field Manual 6-27,The Commander’s Handbook on the Law of Land Warfare,109and assigning it to the BLS as required
reading. Branch into other topics such as the distinction between the United States and international legal
regimes surrounding cluster munitions (such as the dual-purpose improved conventional munition, or DPICM),
landmines, and command-detonated devices like the M18 Claymore and M7 Spider.110Help the attorneys and paralegals understand the legal
framework for the treatment and detention of captured persons,111and make sure they grasp the basics of the targeting process.112
Conclusion
As COL Kristy Radio and her co-authors state, “It’s hard to overprepare for LSCO.”113Preparing along the five LOEs described above, however, is
a good start toward getting ready for a CTC rotation.
Just like with training for an AFT, success at a CTC will come only by preparing well in advance. Whether it be
positioning people in the BLS in the appropriate spots, preparing paralegals to maximize value to their BNs,
planning for breakdowns in communications, developing effective fighting products, or training the force
correctly, you will get out of the CTC experience what you put into it.
The “real world,” with its justice actions, investigations, and ethics opinions, always beckons. But just as you
need to do PT several times a week to prepare for an AFT, you need to make time for CTC preparation.
Although a rotation may not feel “real” when it is still several months out, the more prepared you are upon
arrival, the more effectively the CTC will prepare you, the BLS, and the whole BCT for the day when the mission
itself is “real world.” TAL
Notes
1. This article focuses on preparation for the maneuver, or
"dirt," CTCs, including the Joint Readiness Training Center (JRTC) at Fort Polk, Louisiana, the National
Training Center (NTC) at Fort Irwin, California, and the Joint Multinational Readiness Center (JMRC) in
Hohenfels, Germany. The Mission Command Training Program, based at Fort Leavenworth, Kansas, represents a
different type of CTC that trains divisions, corps, and other Army and joint units. See U.S. Dep't
of Army, Regul. 350-50, Combat Training Center Program para. 1-5(e) (2 May 2018).
2. A well-known shift in focus away from counterinsurgency
and counterterrorism, toward large-scale combat operations (LSCO), makes the division "the Army's principal
tactical warfighting formation." U.S. Dep't of Army, Field Manual 3-0, Operations para. 2-98 (21 Mar. 2025)
[hereinafter FM 3-0]. Nonetheless, the brigade combat team (BCT) remains "the Army's primary combined arms,
close-combat maneuver force." Id. para. 2-99. Although dirt CTCs conduct "division in the dirt"
rotations occasionally, their most-frequent training audience, by far, remains the BCT. For that reason,
this article focuses on a BCT-level rotation.
3. Ideally, as the brigade judge advocate (BJA), you would
start exercising tactical systems and processes as soon as you take the seat.

about Command and Control in Large-Scale Combat Operations, Mil. Rev., Mar. 2023, at 10, 13.
11. This article uses the term "MCP" to refer to the TOC
or CUOPS cell, and "RCP" to refer to the FUOPS cell.
12. Current Army doctrine, now four-to-five years old,
reserves the term RCP for the division and corps level, while affording BCTs only an MCP and a tactical CP
(TAC). See U.S. Dep't of Army, Field Manual 6-0, Commander and Staff Organization and Operations
para. 7-29, tbl. 7-1 (16 May 2022); U.S. Dep't of Army, Field Manual 3-96, Brigade Combat Team paras. 4-42,
4-227 (19 Jan. 2021) [hereinafter FM 3-96]. Nonetheless, doctrine allows the BCT CDR flexibility in
structuring CPs "to meet changing situations," with "CP survivability . . . vital to the success of the BCT
mission." FM 3-96, supra, paras. 4-41, 4-225. CTCs have routinely seen BCTs fight with an RCP or
FUOPS cell in addition to a small MCP and TAC. Compared to 2021–2022, when FMs 6-0 and 3-96 were released,
BCTs are favoring smaller, more dispersed nodes to keep their staffs alive.
13. See U.S. Dep't of Army, Techs. Pub. 6-0.5,
Command Post Organization and Operations para. 1-23 (1 Mar. 2017) [hereinafter ATP 6-0.5]. Some BCTs staff a
fourth node, the administrative and logistics center (ALOC), which is dedicated to sustainment support and
is typically located further to the rear than the RCP. Resist being placed in the ALOC. Although legal
support is doctrinally part of the sustainment Warfighting Function (WfF), the BLS has a role in all six
WfFs in a way most staff sections do not. See U.S. Dep't of Army, Field Manual 3-84, Legal Support
to Operations para. 2-54 (1 Sep. 2023) [hereinafter FM 3-84]. A recent CTC rotation demonstrated that when
the BJA and other BLS members were relegated to the ALOC, they were disconnected from the fight, which
limited their ability to advise on BCT operations.
14. See FM 3-84, supra note 13, para.
3-61.
15. See Gattermeyer et al., supra note
8, at 5. Recent CTC experience shows that bringing three attorneys (including you, the BJA) increases the
total training value. With three attorneys, each has more flexibility to integrate with and learn from the
planning staff and digest the information they are learning about the operations process. Furthermore, with
three attorneys present, they have more opportunities to engage with enablers, such as civil affairs and
psychological operations, on legally related issues arising from their respective activities. If you arrive
with only one other attorney, however, you may find yourselves struggling to keep your heads above water.
16. See FM 3-84, supra note 13, para.
3-27.
17. As Gattermeyer et al. advise, get the SJA involved
early in a manning problem. See Gattermeyer et al., supra note 8, at 8. Help the SJA see the long-term value
to the division and the greater JAG Corps to sending a third attorney. See id.; see also
Colonel Andrew McKee & Lieutenant Colonel Jason Elbert, Embrace the Crucible Experience: An
Intentional Approach to Training Opportunities, Army Law., no. 2, 2022, at 9 (explaining why
division SJAs should engage early in preparing for a CTC rotation) ("[L]eaders within the JAG Corps must
approach training requirements such as . . . [CTC] rotations and Warfighter Exercises (WfX) with
intentionality, devoting serious thought and their own time into ensuring every member of the team gets the
most they can out of these opportunities. . . . [SJA] preparation for these events should start well in
advance of execution.").

20. A VALEX is a BCT-level exercise at home station that
serves as a final rehearsal before the CTC rotation. It is typically controlled by the division staff, with
the division chief of national security law playing the division SJA. As its name implies, the VALEX is
where the BCT staff, including the BLS, seeks to validate its systems and processes prior to traveling to
the CTC.
21. The term "fight night" refers to a period of intense
combat activity, typically at night. During a CTC rotation, expect the BCT to face at least one "fight
night" on defense and one on offense.
22. For example, the ROE may withhold the authority to
employ a certain weapon system to the division commander. If the BCT commander wants that authority, the BCT
staff must prepare an ROE-change request with your advice and then route it to the division commander
through operational channels.
23. See FM 3-84, supra note 13, paras.
3-49 to 3-51.
24. Davis & Young, supra note 6, at 18 ("BLS
and OSJAs can do a couple of things to posture for success: 1) set the dial on risk tolerance and LOAC
compliance in the targeting process; 2) advocate for physical space and staffing; and 3) develop training
objectives aligned with the BLS state of readiness, OSJA guidance, and any follow-on mission with redundant
and analog fighting products to ensure readiness for an austere environment."); see Chairman, Joint
Chiefs of Staff, Instr. 3160.01D, No Strike and Collateral Damage Estimation Methodology glossary (21 May
2021) (defining collateral damage).
25. See FM 3-84, supra note 13, tbl.
3-2 (listing battle-rhythm events requiring legal support).
26. These engagements may be part of the exercise.
27. Recent articles in The National Security Law
Quarterly (NSLQ) emphasize the importance of staff integration and how to accomplish it. Some
articles are written from the division perspective, but their concepts transfer easily to the BCT level. See
Colonel Kristy Radio, Major Wesleigh Cochrane, Captain Javier Diaz, & Captain Jason Vickers, LOAC in
LSCO: Transitioning a Division in the Dirt, Nat'l Sec. L.Q., no. 1, 2025, at 37 (discussing how to
integrate with the staff WfFs); Major Uilisone Tua, The Role of the Judge Advocate in Division Fires
During LSCO, Nat'l Sec. L.Q., no. 4, 2024, at 28 (describing the role of the legal advisor in
supporting deliberate and dynamic targeting); Captain Trevor Deakin, Earn Your Seat, Nat'l Sec.
L.Q., no. 1, 2025, at 44 (highlighting the importance of engaging outside the legal practice area and not
bunching up in one command node).
28. See U.S. Dep't of Army, Field Manual 5-0,
Planning and Orders Production para. 5-10 (4 Nov. 2024).
29. See FM 3-84, supra note 13, paras.
3-25, 3-50.
30. See Radio et al., supra note 27, at
41; McKee & Elbert, supra note 17, at 9–10 (underscoring the importance of integrating with the
battle staff very early and "baking in" LOAC considerations). "In combat, the pace of battle will move too
quickly for on-the-spot legal advice. Success will require LOAC considerations during planning, a deep
understanding of the commander's targeting philosophy, and iterative war game discussions that involve legal
considerations." McKee & Elbert, supra note 17, at 9.
31. The notion of JAs taking on collateral duties outside
their legal responsibilities may be controversial, for, at first blush, the practice appears to be
prohibited by AR 27-1. The regulation states, "JAs will perform only professional legal duties for which
they are trained. They should not perform any nonlegal duties." U.S. Dep't of Army, Regul. 27-1, Judge
Advocate Legal Services para. 3-6(c) (24 Jan. 2017) [hereinafter AR 27-1]. Nonetheless, fulfilling a
collateral duty within the MCP to maintain a seat there does not create a conflict of interest, and, as
explained above, doing so may actually enhance your ability to provide legal advice. See id. para.
3-4(a). Therefore, do not fear accepting collateral duties, but accept only those that enable or enhance
your ability to perform core legal functions.
32. But see Davis & Young, supra
note 6, at 17 ("Failing to fully staff a CTC rotation with legal personnel sends an implicit message
that providing legal services in LSCO is not as important as our home-station mission, undercutting an
effort to show the importance of legal personnel regardless of the type of conflict.").

Kerwin, Judge Advocates on the Loop, Nat'l Sec. L.Q., no. 1, 2025, at 29, 31 ("JAs will add the
most value before conflict by educating commanders and understanding how the unit intends to fight. This
allows for anticipation of legal issues and resolving those issues in advance . . . .") See also

confident in their ability to conduct a LOAC analysis without a JA and have confidence that their
subordinates can do the same. This confidence can only be achieved by engaging in debates about the LOAC and
sharing ideas up, down, and across echelon.").
51. Although paralegal specialists are not authorized to
practice law, they are expected "to primarily perform duties of a legal nature," which may include
discussions about what the law means and requires. FM 3-84, supra note 13, para. 3-29.
52. See Beagle, Berger, & Einhorn, supra

53. See Gattermeyer et al., supra note
8, at 7–8.
54. This agreement meant the paralegal could not be
pushed out to the BN forward line of own troops (FLOT).
55. In contrast to this experience at JRTC, a reported
trend at NTC is that paralegals are assigned to BN S1 sections in combat trains command posts (CTCPs), which
are usually 10-20 km back from the forward line of own troops (FLOT), closer to the brigade support area.
This practice generally makes it impossible for paralegals to have much involvement in the fight. For this
reason, work to keep paralegals out of CTCPs.
56. See FM 3-84, supra note 13, para.
3-29 ("Battalion paralegal Soldiers are assigned to the S-1 section of each subordinate battalion.").
57. Bear in mind, however, if you face an uphill battle
convincing BNs to allow their own paralegals to perform legally related duties in LSCO, the struggle will be
even harder to get them to employ non-organic paralegals on anything but perimeter security or basic Soldier
tasks.

from SIPRNet-based systems, toward a "secure but unclassified–encrypted" (SBU-E) environment. See Lauren C.

66. An example from a recent rotation is typical of comms
challenges: A BN paralegal was unable to use an assigned comms platform. He found a buddy in the BN S4
section and climbed into his truck. The paralegal duly borrowed the Soldier's Joint Battle Command–Platform
(JBC-P) device to send a message to the BLS at the BCT HQ. The BLS did not have its own JBC-P device, but
another BCT HQ staff member relayed the message to the BLS several minutes later. Nevertheless, by the time
the BLS was able to respond to the BN S4's user name, the paralegal had already climbed out of the truck.
The BN S4 Soldier either did not know whom the message was intended for or did not want to be bothered, so
the communication failed, and neither the BLS nor the paralegal knew what had happened until the final
after-action review.
