There are no easy days in the desert of the National Training Center (NTC), especially for
commanders. The NTC’s Box is an unforgiving environment that tests our ability to fight and lead through
constant contact and incomparable demands for our time, our authority, and our direct and organizational
leadership. We fail to manage our sleep cycles in an attempt to sprint the entire fourteen days of simulated
large scale combat operations during the force on force and live fire periods, insecure of where to best
place ourselves before and during the fight, and frustrated that our staff cannot turn our guidance into
fighting products faster. We look back over our shoulders with guilt that we failed to progress as far as we
wanted in our collective training plans at home station. We experience frustration that our operational
readiness rate is not as high as we had hoped, due to a combination of long lead time parts and mismanaged
service programs, and we are equally frustrated about the significant personnel turnover right before our
rotation. We are confused, angry, and disillusioned by the role our higher headquarters should have, did, or
did not play in our path to the rotation. I have heard all the justifications and am equally complicit,
having said and believed a version of these same words myself. Then, over two years ago, in February 2023, I
was tested, falling short many times during rotation 23-05 with the Spartan Brigade of the 3rd Infantry
Division. If I could give myself advice before that rotation on how to better prepare myself, my leaders,
and my organization with the knowledge and lessons that I have now…this is what I would say: “As the
commander, I will.”
“The first step to awesomeness is acknowledging where you suck.”
- Former COG
This is for commanders, from a commander. The following thoughts are my observations and
recommendations informed by my own failures, grounded in doctrine, and enabled by others coaching me as I
continue to learn alongside incredible leaders training to conduct large scale combat operations. First, the
desert does not care (and neither do our adversaries). We are deployed to the NTC to lead our Brigade Combat
Team in the crucible of ground combat with the team we brought, the team we are still developing, and the
team that deserves our best. Second, the leadership factory of the high Mojave Desert will expose us by
combining the unforgiving physical environment and a world class sparring partner in the Opposing Force
(OPFOR) who will employ all nine forms of contact, never cheating, but doing their best to make every fight
unfair. Finally, there is no magic formula to ‘win’ at the NTC. Presence, toughness, and fundamentals in
training are a great start but do not guarantee anything. Commanders must be aggressive by leaving nothing
at rest, fight to generate combat power, and make multiple forms of contact with the enemy constantly,
especially when synchronizing brigade efforts to dominate the close fight. The article is commander-centric,
using the framework of the Army operations process: plan, prepare, execute, and assess, as well as the
commander activities: understand, visualize, describe, direct, lead, and assess to train commanders so they
can fight better, period.

Plan
As the commander, I will remember that I am the most experienced staff officer in my formation
and while I am not on the staff anymore, I still owe the staff my time. My experience helps us abbreviate
for efficiency and effectiveness. If I am upset at the staff because they are not giving me the product I
want as fast as I want, I bear the responsibility to fix it. This is where I understand, visualize, describe
and direct with the staff and subordinate commanders.
“We do these things, not because they are easy, but because they are
hard” - General (Retired) Stanley McChrystal
I will lead through the Majors and subordinate commanders with
simple, clear guidance and priorities:
- The Executive Officer will control time and a battle rhythm that integrates the
staff so they do the work in the main command post as well as the admin and logistics operation center:
maintain staff running estimates, generate the required inputs and outputs of battle rhythm events, and
help the commander think by thinking for and like the commander.
- The Operations Officer will synchronize the plan in time and space: ensuring all
capabilities and warfighting functions are accounted for and focused where the commander directs
domination in the close fight, building a battlefield framework that allows focus and tempo with
prioritization, and creating the minimum executing products required to fight.
- The battle rhythm will allow us to plan the next operation while executing the
current one so planners develop a plan that is grounded in reality.
- I will not project how good I was on my last
day as a Company/Battalion Commander or Battalion/Brigade Field Grade onto my leaders. I will
coach them. I am their trainer.
- I will specify responsibilities and
authorities at echelon as well as the minimum number of execution products the staff must develop
for planning and for fighting. Leaders two levels down are my
primary customer.
- I will not be an observer of the Military
Decision-Making Process (MDMP) because I will drive the 1/3 to 2/3 rule by developing and issuing my
own planning guidance, my commander’s intent, and by directing the course of action.
I will develop and approve the essential fire support tasks with my senior
fire supporter, the concept and priorities for sustainment with my senior sustainer, and approve
priorities across the warfighting functions with the subject matter expert. I will endeavor to
leverage information and make first contact with something that is not a human.
- I will direct the senior non-commissioned
officers (NCOs) to hold the unit accountable with clear authorities that get results.
The Operations Sergeant Major will ensure the command post and staff have the
infrastructure and resources to plan for the next fight while executing the current fight from a
standardized common operational picture that remains current, is common at echelon, and enables me
to command and to control. The Command Sergeant Major (CSM) will move to my specified points of
friction that ensure we are generating combat power today and preparing for tomorrow. These tasks
could include: observing the arrival and download of combat vehicles or throughput of Multiple
Integrated Laser Engagement System (MILES) installation to confirm prioritization and resource
allocation, the execution of maintenance operations in an assembly area of the main effort unit, and
ensuring the reception and integration of non-organic units and task organization changes.

Prepare
The major activity where a commander identifies and mitigates risk through presence and
interaction with leaders across the organization using deliberately planned battlefield circulation,
directing rehearsals, and ensuring the right amount of detail and control exist within the plan. This is
where I continue to improve my understanding, visualization, and description. I increase the strength of my
directing and leading while assessing through back briefs, battlefield circulation, and feedback from the
CSM.
- I will give clear guidance for
rehearsals: type, sequence, and expectations of leaders in execution.
Sustainment is the foundation and run by the Brigade Combat Team Executive
Officer (BCT XO) in coordination with the Brigade Support Battalion (BSB) Commander. The Squadron
Commander and Fires Support Coordinator run the information collection and fires to shape the
environment, and the Brigade S3 runs the combined arms rehearsal to confirm decisions,
intent, risk, and triggers (DIRT). The Brigade Engineer Battalion Commander ensures we are integrating
the protection warfighting function throughout the battlefield framework.
- I will communicate what fighting products will
be used and the Brigade XO will ensure they are validated during the execution of rehearsals by
specifying what conditions must be set before critical event execution or decisions are made.
- I will conduct battlefield circulation to
ensure my intent is understood at echelon, to further ensure subordinate execution of MDMP and troop
leading procedures (TLPs) and to improve my understanding of what the staff is briefing from their
staff running estimates. I will endeavor to conduct commander
visualization and dialogue on key terrain if possible.
- I will drive the execution of rehearsals not
as a measure of performance but a measure of effectiveness, with multiple repetitions of friction
points and transitions as required. I will ensure we can
maneuver the network to command and control at distance, anticipate sustainment requirements at
scale, protect critical capabilities, and exploit opportunities through disciplined initiative
thanks to detailed control measures and simple, clear intent that is understood at echelon.
- I will direct the Operations Sergeant Major to
ensure the terrain model provides the scale, the terrain relief, and the control measures required
for an effective rehearsal while enabling the Headquarters and Headquarters Company (HHC) Commander
and 1SG to develop the command post (CP) transition plan. The
CSM will conduct pre-combat inspections of critical task execution and commodity preparation. These
tasks could include: observing subordinate breach and non-standard casualty evacuation rehearsals
and ensuring mine plows and rollers are mounted, operational, and the crews are proficient, as well
as medical node critical equipment and personnel readiness. The CSM’s pre-combat checks help assess
our readiness to execute the start point (SP) and / or the line of departure (LOD).

Execute
The major activity where a commander struggles the most to place themselves and where we learn
if our command post is conducting the six command post functions effectively. Observations from the
Russo-Ukraine conflict often drive us to emphasize survivability over functionality, at our own peril. The
commander must be able to communicate in order to command and control with the clear emphasis on directing,
leading, and assessing. Work to function first, and then survive.
Figure 4. Daily Questions, Diven 23-05 (Graphic by author)
- I will ensure the required
conditions are set before executing critical tasks and actions, noting that the time may be sooner
than expected and with less conditions set than expected. Not
having all the conditions set is simply risk and I will determine what is prudent and
acceptable.
- I will not be the Battle Captain nor the Chief
of Operations (CHOPS) as the XO runs the MCP. I will fight from
my command post because that is where the information is relevant through the staff’s running
estimates, updated on the common operational picture and good reporting in accordance with our
standard operating procedures (SOPs) and my approved commander’s critical information
requirements.
- I will not abandon the main command post
because I want to move forward in a tactical command post (TAC) or mobile command group (MCG) so I
can better ‘see’ the fight. If I don’t want to fight from my CP
it is likely because the CP is not functional. The TAC exists as a temporary node that enables the
commander to command and control through a transition period or a discrete event; it is not
enduring. The TAC maintains the people, the processes, and platforms the commander needs to fight
for 6-12 hours at most. The MCG enables battlefield circulation.
- I will use the fighting products validated
during the execution of rehearsals until conditions change to the extent we transition to the next
phase or we conduct the rapid decision making and synchronization process. The XO ensures the staff maintains
updated running estimates and continues to
plan for the transition to the next phase while the S3 ensures timings, triggers, and
synchronization of the current fight.
- I will hold the Operations Sergeant Major
accountable for the COP remaining current, the duties and responsibilities of the CP are being
executed, and the HHC Commander and 1SG are prepared to execute the CP transition plan.
The CSM will move to specified friction points to ensure transitions occur as
planned. These tasks could be: ensuring mission or combat configured loads are prepared to
move to their designated location according to planned triggers, forward logistics elements and medical
nodes are moving or postured as planned, or inspect coordination and risk mitigation efforts between two
converging elements.
Assess
The major activity where a commander must trust and use judgment. We must trust in subordinate
reporting, weighing heavily when a subordinate commander reports their own assessment of the situation. The
commander synthesizes the inputs and information provided by the staff and applies judgment in decision
making. Sometimes a commander must trust their own instinct, leveraging the coup d’oeil or inward eye that
Clausewitz talks about where commanders develop absolute clarity in battle and execute or adjust the plan
accordingly. The emphasis is rightly on assessing but also how the commander’s assessment then feeds back
into the other commander activities as a continuous process.
Figure 5. Spartan Brigade tanks fire during the live-fire portion of the NTC rotation (Photo by author)
- I will incorporate reporting
from higher headquarters, subordinate units, and the staff to update my own commander’s running
estimate.
- I will expect commanders to report their
assessments with relation to being on or off plan and on or off time to understand our operational
tempo and if prioritization needs to change. I will expect
commanders to solve problems through their assessments, that are often transparent to me.
- I will expect commanders and staff to make
recommendations to maintain shared understanding, seeking opportunities, and conducting risk
management throughout execution.
- I will share my assessment vertically and
horizontally because our brigade is fighting as part of a division, amongst Special Operations
Forces, and in support of Joint and Multinational Forces.
- I will hold the Operations Sergeant Major
accountable for maintaining combat power, readiness, and endurance across the staff and in the
command posts in coordination with the Executive Officer. The
CSM will provide candid feedback of the operational tempo and stress on the force to help
assess where to consolidate and reorganize as a planned or unplanned transition. The CSM will also
provide an assessment of how we are taking care of our casualties and regenerating combat power through
the evacuation process, mortuary affairs, and replacement processes.

So What
We (brigades and commanders) understand the importance of establishing an operational tempo
but are challenged to execute the current fight while simultaneously planning and preparing for the next
one. We struggle to describe specific conditions required for execution across the warfighting functions to
truly combine arms in time and space. We continue to experiment with command post configuration by balancing
survivability with functionality. We are getting better at visualizing our sustainment as the foundation of
our operations with anticipation and not as an afterthought. We try to enable command and control by
maneuvering the network across a multi-channel Primary, Alternate, Contingency, Emergency (PACE). We see the
need for simple fighting products, that enable commanders to conduct commander activities and employ senior
enlisted leaders to drive action. We see the need to find the enemy and make contact using a non-human
first, and maneuver to employ all-domain fires. We should be happy with our intent and efforts to improve
and fight better, but never satisfied.
The NTC remains focused on warfighting and developing leaders in the most stressful and
realistic environment in preparation for future combat. There are no easy days in the desert and this is a
leadership factory where one cannot help but be better after a rotation. Our observations are intended for
professional development, to inform home station training, and most importantly to prepare leaders for the
challenges of large-scale combat operations by preparing us to not only win the first fight, but dominate
our adversaries through the last fight.
This article reflects the sweat, the parts hung, the caked dust, and the orders issued over
the net at the high Mojave desert that builds leaders, builds readiness, and is helping to transform our
Army. The embedded products are not the answer, but “a way” to help leaders drive the operations process and
fight better. The NTC and Operations Group exists to Train the Force. We must Lead, Train, and Win. Now,
let’s go fight.
