Brian E. Tierney
Company D, 1st Battalion, 12th Cavalry, 1st Cavalry Division (Airmobile)
21 May 1968
Republic of Vietnam
For extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam:
Specialist Four Tierney distinguished himself by exceptionally valorous actions on 21 May 1968 while serving as a radio telephone operator near Quang Tri City. Specialist Tierney and two other soldiers entered a small village to capture a Viet Cong whose position had been spotted from a helicopter. When the point man saw the enemy crouching in a thicket and ordered him to surrender, the communist started to stand up as if to give himself up, but suddenly threw a grenade that he had been concealing. Seeing the deadly missile land a few feet from himself and his companions, Specialist Tierney shouted a warning and lunged towards the grenade to shield the others from the blast. Specialist Tierney was mortally wounded when the grenade exploded, but by his selfless act he saved his companions from injury. Specialist Four Tierney’s extraordinary heroism and devotion to duty, at the cost of his life, were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
