The People’s Republic of China (PRC), often called the pacing threat of the United States of America, remains focused on its aspirations for dominance in the INDOPACIFIC region. The PRC’s overall growth and persistent actions in all domains against the U.S. and our allies pose significant challenges in the area, so much so that it is the focus of the U.S. National Defense Strategy (NDS) and National Security Strategy (NSS). The Island of Guam is the most strategically located U.S. Territory in the INDO-PACIFIC region. It is in the second island chain in the Pacific Ocean and, since 1945, has provided the U.S. with a location to project land, air, and sea power. Guam is home to about 170,000 American citizens from all branches of military service, including family members, DOD civilians, and most importantly, the indigenous people who call Guam home. For the safety and security of U.S. possessions and its people and to prepare the most significant Army footprint on the island for Large Scale Combat Operations (LSCO) against a formidable threat, the National Guard Bureau needs to support the immediate force structure implementation for air defense and cyber capabilities for the Guam Army National Guard (GUARNG) to support the defense of Guam and the Marianas, force modernization, and increased readiness in a multi-domain environment in the INDO-PACIFIC region.

The Guam Army National Guard leadership has great aspirations as the primary defenders of our island. From an ethical, moral, and legal view, our obligations to the U.S. Constitution and the oath we swore to protect America from our enemies are paramount to us as a people and as Soldiers from Guam. We hold the safety and security of our island and people close to our hearts, and we know the needs of the U.S. do not outweigh the needs of our island. We want to be known as the generation who did the most to protect our land, culture, traditions, and people in case of conflict. In the NDS, Guam is specifically mentioned numerous times under the topic of Homeland Missile Defense, stating that if Guam or any other U.S. Territory is attacked, it is considered an attack on the homeland, and the U.S. will respond appropriately.

Additionally, Guam is an essential operating base, home to crucial regional power projection platforms and logistical nodes. Finally, the buildup of Guam’s missile defense will be a crucial component of integrated deterrence and bolster U.S. strategy in the region (U.S. Department of Defense, 2022). Convincing the Army to support force structure changes to our organization directly supports the NDS if GUARNG can gain air defense and cyber capabilities. Our largest unit is an Infantry Battalion, which is authorized 685 positions over five units and has never met 100% of the assigned strength. It is currently at about 90% filled, including Soldiers who are pending discharge or under a category called NOVAL, which identifies Soldiers who have not attended drill assemblies for over nine periods. By consolidating Soldiers from the five units into three infantry units, gaining an air defense artillery unit, and refocusing recruiting efforts against the new unit, our organization would significantly improve our overall posture to defend the island against a potential attack by the adversary. In a Congressional Review of the Air Defense Artillery force structure in 2020, the Army has proposed that the Army National Guard receive three Indirect Fire Protection Capability (IFPC) units to defend against fixed and semi-fixed assets at the corps and division levels (Feikert, 2020).

Furthermore, the Army Structure Memorandum 2025-2029 (ARSTRUC) published on February 27, 2024, indicated the activation of four Active-Duty Indirect Fire Protection (IFP) battalions and one Patriot/ IFPC composite battalion amongst other units in support of the defense of Guam (U.S. Department of the Army, 2024). Since the Patriot unit is activating in Guam, an argument can be made that creating these positions under the Guam Army National Guard force structure makes more sense. Recruiting the patriotic residents of Guam into those positions could save time, money, and logistics for the military. Guam National Guard Soldiers would not be required to rotate in and out of Guam as the unit would be organic to Guam. Again, residents of Guam would proudly serve in this unit, knowing they would play a crucial role in the defense of Guam.

Regarding missile defense, specifically the Iron Dome, Total Army Analysis already supported efforts to acquire more missile defense capabilities, namely, the Iron Dome, of which the U.S. has already received two from Israel. One Iron Dome was deployed and tested in 2021 in Guam by the 2-43 Air Defense Artillery Battalion out of Fort Bliss. Although the Iron Dome test was met with some pushback by the community, the capabilities displayed by the defense system proved that Guam would ultimately be protected more than if they had to rely on just the THAAD battery currently stationed in Guam. The Iron Dome was tested to validate successful integration into THAAD architecture to make it work towards a more layered defense (Olson, 2022). Guam is a patriotic land rich in America’s beliefs of freedom and prosperity. Guam has some of the highest recruiting numbers per capita across all services, and this pride in serving our island and country extends into the Marianas Islands. Specifically, to the Guam Army National Guard, recruiting on Saipan, an island in the Commonwealth of the Northern Marianas Islands (CNMI) with a population of about 44,000, has been gaining momentum since reopening the recruiting efforts there with 52 recruits since May 2022. This point offers that creating an ADA force structure in the GUARNG could soften the “tyranny of distance” issue when transporting something like the Iron Dome from Texas to Guam. Transporting it by plane could take 10-12 hours, which gives the enemy much time to inflict damage. Imagine the response time if the GUARNG had a force structure to recruit against and gain Soldiers who were qualified to operate the Iron Dome, and it was already prepositioned in Guam. In this scenario, they may have a chance to survive a missile attack as the most likely course of action from the PRC or any enemy.

Guam previously had signal capabilities, starting with a Signal detachment from 1991 to 2007. 2009, the 721st Signal Company served the Guam National Guard as a competent network and tactical signal systems unit. The unit remained at 100% strength during most of its existence before finally inactivating in March 2016. Once the unit was inactivated, Soldiers who decided to stay in the organization were reassigned to other units, mainly in the infantry battalion. Most Soldiers who ended up in a career field outside of signal left the organization either to active duty or some other reserve component or branch of service with available signal positions. For 25 years, the GUARNG remained semi-relevant in this domain. In this operating environment, cyber has become a priority by Army doctrine, the NDS, NSS, the NCS, and the GUARNG. A cyber and signal company or detachment is another capability the GUARNG leadership brings up nationally.

The Guam Army National Guard is a proud organization. Every Soldier, from the private who recently returned from basic training and advanced individual training to The Adjutant General, understands it is a critical time and place in the region. One day, the GUARNG will be forced to defend its home from those who do not share the same views as the U.S. to maintain a free and open INDO-PACIFIC region. With an updated force structure to include air defense and cyber capabilities to help defend the homeland, GUARNG can remain a ready and relevant force. We are the first responders to a crisis or conflict in Guam. The National Guard Bureau must support the immediate force structure concerns to support the Guam Army National Guard’s readiness and modernization. We will ultimately be able to defend Guam, its people, and the Marianas.
