Specialist E-5 Robert M Casillas enlisted in the Army in May 1967. Following basic training he was sent to Vietnam as a medical specialist. He soon faced the brutal reality of war during the Tet Offensive. Amidst the intense fighting and heavy casualties, he used his medical skills while helping to repel the relentless Viet Cong attacks. Beyond the battlefield, Robert and his team conducted vital MEDCAP missions, venturing into remote villages to provide crucial medical care to civilians cut off by the war. Robert performed similar duties elsewhere in Vietnam before returning to the states in December 1968. He became a medical instructor at Fort Sam Houston where he completed his service. His military tour earned him the Army Good Conduct Medal, Vietnam Campaign Medal with three Battle Stars, National Defense Medal, Meritorious Unit Citation, Medic Badge, and promotion to Specialist 5 (E-5).
