Ruppert Leon Sargent (January 6, 1938 – March 15, 1967) was a United States Army officer and a recipient of America's highest military decoration—the Medal of Honor—for his actions in the Vietnam War.

[2] On that day, while in Hậu Nghĩa Province in the Republic of Vietnam, Sargent threw himself on two enemy hand grenades, sacrificing himself but saving the lives of two men nearby.

[5] Lieutenant Sargent's official Medal of Honor citation reads:[6] ...For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty.

He and his demolition man moved in to destroy the booby trap and cover which flushed a Viet Cong soldier from the tunnel, who was immediately killed by the nearby platoon sergeant.

By his courageous and selfless act of exceptional heroism, he saved the lives of the platoon sergeant and forward observer and prevented the injury or death of several other nearby comrades.
