Aberdeen Proving Ground, Md. – Col. Troy S. Johnson took command of U.S. Army Garrison Aberdeen Proving Ground (USAG APG) on June 6, 2025, with a clear vision: to foster open communication, strengthen partnerships, and build on a storied history of innovation and service.
As he settles into his new role, Col. Johnson brings more than three decades of Army experience—five combat tours, a breadth of leadership positions, and a steadfast commitment to teamwork—to the Army’s oldest active proving ground.
A Journey from Enlisted Soldier to Garrison Commander
A native of Wakefield, Virginia, Col. Johnson began his Army career in 1994, enlisting fresh out of high school. Eight years later, after demonstrating exceptional aptitude and leadership potential, he earned his commission as a Quartermaster Officer through Officer Candidate School at Fort Benning, Georgia. His academic achievements include a Bachelor of Science in Business Management with a Minor in Finance from the University of Maryland University College, and a Master of Strategic Studies from the U.S. Army War College—the capstone of a professional military education that also features the U.S. Army Command and General Staff College and the Combined Logistics Officer Career Course.
Over the years, Col. Johnson steadily progressed through increasingly complex roles: from platoon leader in supply and services to battalion commander, and across multiple staff assignments in divisions spanning the globe. He commanded the 54th Mortuary Affairs Company at Fort Lee, Virginia, served as Deputy Director of Logistics for U.S. Forces Japan in Tokyo, and led the Army Field Support Battalion at Fort Hood, Texas. Most recently, he served as the State Inspector General for the Maryland National Guard, where he oversaw readiness, accountability, and the welfare of Soldiers across the state.
A Leader Honored by Service
His distinguished record is reflected in a ribbon rack that includes the Bronze Star, Defense Meritorious Service Medal, Meritorious Service Medal, Joint Commendation Medal, Army Commendation Medal, and Army Achievement Medal—alongside the Air Assault and Parachutist Badges. These decorations underscore both combat valor and sustained excellence in staff and command roles.
Yet, Col. Johnson readily credits his teams. “Every assignment—from convoy operations to the complexities of mortuary affairs—taught me one thing: mission success depends on the soldiers beside you,” he says. “Their ingenuity, resilience, and unwavering dedication are what truly earn the awards.”
Looking Ahead at APG
When asked what he most looks forward to at APG, Col. Johnson’s enthusiasm is palpable.
“I am eagerly anticipating the opportunity to engage with the exceptional personnel at Aberdeen Proving Ground,” he says.
He also emphasizes the importance of community ties:
“I look forward to strengthening our partnerships with the local community.”
APG has long been a hub, not only of advanced defense research and development, but also of close collaboration with civilian stakeholders. From technology transfers to family programs and local economic impact, Garrison leadership plays a critical role in ensuring the installation’s success and its positive footprint in Harford County and beyond.
First Impressions and Surprises
Col. Johnson’s transition to APG has yielded both affirmation and surprise.
“What I find particularly commendable about APG is the strong sense of community and camaraderie among the personnel,” he notes.
He also appreciates the installation’s historic legacy:
“The shared pride in our collective mission and the commitment to excellence are truly inspiring. Furthermore, the historical significance of this site and its vital role in advancing defense technology provide a rich backdrop to our efforts here.”
The most striking aspect for the new commander has been the depth of collaboration across organizations.
“I have been pleasantly surprised by the remarkable level of collaboration that exists among the various departments and units,” he says. “The readiness of individuals to share knowledge speaks volumes about the robust culture of teamwork and innovation at APG.”
Commitment to Transparency and Dialogue
At the core of Col. Johnson’s leadership philosophy is a belief in transparent communication.
“I would like the community to know that I am profoundly committed to supporting both our military personnel and the community that surrounds us,” he says. “I value transparency and open dialogue, and I am eager to hear from both the team at APG and the residents of Aberdeen.”
A Family Rooted in Service
Behind every Army leader stands a supportive family, and Col. Johnson is no exception. He and his wife, Shanna, are the proud parents of three children: Alexis, Troy II, and Sean.
“Their sacrifices, encouragement, and patience have allowed me to serve at every level of command,” he says. “I look forward to showing them the community here and involving them in APG’s family events.”
An Open Invitation
Col. Johnson extends an open invitation:
“I would like to take this opportunity to express my enthusiasm for the chance to work alongside everyone. I look forward to fostering connections and exploring the many avenues of collaboration available to us as we uphold our mission at APG. Please feel free to reach out to share your ideas and insights; together, we can make a meaningful impact.”
With his extensive experience, steadfast commitment, and genuine passion for service, Col. Johnson is poised to lead APG into its next chapter—one defined by innovation, partnership, and shared success.
