First Sergeant Otis L. Harbuck

Over the course of a remarkable 38-year career, First Sergeant Otis L. Harbuck embodied the steadfast spirit, resilience, and unwavering dedication that define the Texas Army National Guard. From his enlistment in 1956 to his retirement in 1996, 1SG Harbuck served as a cornerstone of the Guard’s transformation across decades of organizational change, technological evolution, and operational readiness.
Beginning his service with Company A, 386th Engineers in Lufkin, Texas, Harbuck answered the call of duty early in his career when his unit was mobilized during the Berlin Crisis as part of Operation Iron Dragon. His leadership and composure under pressure would become hallmarks of his service. Promoted to Platoon Sergeant in 1963, he assumed duties as the full-time Administrative Supply Technician (AST) for the Lufkin unit—a position he would hold with distinction for the next 31 years.
Throughout his career, 1SG Harbuck guided his unit through five major reorganizations, each of which demanded not only technical and tactical transition, but also mentorship, stability, and vision. Whether transitioning from engineers to armor, from armor to artillery, or integrating new platforms such as the M48A1 tank or the M728 Combat Engineer Vehicle, Harbuck’s ability to lead Soldiers through change became a defining aspect of his leadership legacy. His deep institutional knowledge, hands-on involvement in training, and quiet professionalism ensured mission readiness while maintaining the esprit de corps of the unit.
In 1972, the Lufkin unit—then Company C, 112th Armor—earned an "Award of Commendation" following a superior rating by the Inspector General of the Fifth U.S. Army. True to form, 1SG Harbuck took the opportunity to publicly promote the unit and the Guard by sharing news of the recognition and its newest equipment with the local press. This passion for community engagement became a recurring theme: whether organizing vehicle displays at local fairs, parades, and schools, or representing the Guard at civic events, Harbuck was a tireless ambassador for the Texas Army National Guard.
His leadership was not confined to traditional boundaries. Even as reorganizations brought new challenges, such as converting artillery troops into combat engineers—or vice versa—1SG Harbuck remained a constant presence, cultivating proficiency and pride in his Soldiers. During one of the final reorganizations to Battery C, 1/133rd Field Artillery, he served as both First Sergeant and full-time unit administrator, roles that demanded both long-range focus and day-to-day commitment to the welfare of his troops.
A consummate professional, Harbuck pursued ongoing education throughout his service. He completed the 14th CBRN Enlisted Course, Personnel & Administration Course, Senior NCO and First Sergeant Courses, and graduated with honors from the Admin Supply Technician program. He was known as a mentor and teacher, always willing to share his experience with junior Soldiers and new leaders.
Among his many honors, 1SG Harbuck received the Legion of Merit, the Army Achievement Medal with two oak leaf clusters, and the Army Reserve Components Achievement Medal (5th award). His state decorations include the Lone Star Distinguished Service Medal, Texas Medal of Merit, Adjutant General’s Individual Award, Texas Faithful Service Medal (7th award), Texas Federal Service Medal, and the Army National Guard Recruiting Badge.
Even in retirement, he continued to mentor officers, NCOs, and enlisted personnel, building camaraderie and offering guidance in informal but meaningful ways. His legacy earned him a brevet promotion to Sergeant Major.
