Since June 14, 1775, the United States Army has been a symbol of courage, discipline, and dedication. As the nation celebrates the Army’s 250th “birthday,” the Georgia Tech Research Institute (GTRI) proudly honors its own team members whose careers transitioned from the frontline to the “frontlines” of research.

GTRI's mission to "serve national security" resonates with these veterans, whose military experiences now shape their innovative approaches to technology and research.

In a special episode of the Georgia Tech Research podcast, four GTRI professionals who are Army veterans share their personal journeys, reflections on Army history, and insights on how military service has informed their current roles. Each GTRI soldier’s story highlights how the Army's timeless values and methodologies enrich GTRI's mission-driven culture.

The interviews are conducted by Mike Curtis, a GTRI Research Associate and U.S. Marine, assisted by Christopher Weems, a GTRI Communications unit writer and civilian. This podcast episode stems from their keen respect for the U.S. Army.

Paul Arnold, Project Director, Cyber & Information Security

Paul Arnold’s path exemplifies disciplined transition. His Army tenure involved managing complex cybersecurity operations essential to national defense. Post-service, Arnold translated this expertise into a key leadership role at GTRI. His Army-imbued commitment to rigorous security frameworks and strategic planning now fortifies GTRI's critical cybersecurity projects, protecting the integrity of defense networks and systems.

On Army values: “Part of the Ranger creed is 'I'll never leave a fallen comrade.' We said it every day, but living it was entirely different. I always felt these guys would never let me down. They were brothers in arms."

On the lasting impact the Army has had on him: “Even today, I can't leave the house without making my bed—not in a crazy way, but it sets the tone. Start each day positively, doing your best. That discipline is Army, through and through."

Charles (Chuck) Eassa, Senior Research Associate, Strategic Capabilities Office

With over three decades of service, including crucial roles in Operation Iraqi Freedom and NATO information operations, Chuck Eassa brought a keen strategic mind to complex battlefield scenarios. At GTRI, his expertise now informs projects supporting the Department of Defense (DoD) Strategic Capabilities Office, particularly in Europe. Eassa's experience and insights on combined arms operations and strategic communications significantly bolster GTRI’s role in anticipating and addressing modern military challenges.

On what was the most pivotal event in U.S. Army history: "It's not just one event—it's those critical seven years from 1938 to 1945, when the Army grew from a small, ill-equipped force to an eight-million-strong powerhouse. Those same people set the conditions for the peace we've enjoyed."

On why he joined the U.S. Army: "I wanted to take care of the guy on my right and on my left. I didn't want to be a banker or businessman—I wanted to be part of a high-performing team. That's exactly what the Army offered."

Jeremy Flight, Director of Strategic Engagements - Europe

Jeremy Flight leverages his extensive Army leadership experience, including his tenure as executive officer of the historic 2nd Cavalry Regiment, to lead GTRI’s advanced systems research from Wiesbaden, Germany. His understanding of multinational operations directly translates into strategic insights for testing sensor, avionics, and cyber systems—key capabilities that sustain operational superiority and preparedness. Also, Jeremy is an avid military historian.
On what was the most pivotal period in U.S. Army history: "The Revolutionary War showcased discipline, grit, resilience, and adaptiveness—core components still in our doctrine today. Without those traits, we wouldn't have the United States as it is today."
On what he is most proud of from his Army service: "There's no stronger bond than knowing the person to your right and left has your back. We raised our hands because we believed in preserving our fragile democracy. That purpose is what makes me most proud."

Zachary Hartzell, Research Engineer, Applied Systems Laboratory (ASL)

Zachary Hartzell’s dual role as a GTRI systems engineer and an active Army Reservist underscores how GTRI employees can “cross-train” for military precision and technical innovation. His seven years of Active Duty, notably supervising Patriot missile air defense operations, ingrained a meticulous approach to systems integration. Today, Hartzell continues serving the nation, bridging tactical excellence and technical mastery to develop resilient and adaptive defense solutions at GTRI.
On what was the most pivotal period in U.S. Army history: "World War I was pivotal because it marked the U.S. Army becoming a truly global fighting force. That moment shaped our operational identity across the entire world."
On what Army lesson he has brought to GTRI: "You can learn from everyone. My soldiers taught me things and challenged me to think differently. I've brought that same openness to collaboration here at GTRI."

The Army's values—Loyalty, Duty, Respect, Selfless Service, Honor, Integrity, and Personal Courage—are repeated often in these interviews as these soldiers say they still apply these values at GTRI. This podcast is a salute to the integration of military ideology and scientific innovation. As we reflect on 250 years of the U.S. Army, these interviews highlight how its legacy continues in every corner of the Institute.
