FIRST SERGEANT DONALD M. BIGGIN, JR., received the Distinguished Service Cross for his extraordinary heroism in action on 18 March 1969 during a reconnaissance-in-force mission in Binh Duong Province, Vietnam. Then a member of the 11th Armored Cavalry his unit’s armored vehicles attempted an on-line assault on an enemy bunker complex, but were stalled by antitank fire. Observing that the unit’s weapons were not effectively neutralizing the bunkers, Sergeant Biggin dismounted and engaged two hostile bunkers with an M-72 rocket launcher, destroying them completely. While supervising the evacuation of his wounded men, he noticed a fire burning in one of the tracks and rushed to assist the wounded crew members who were trapped. Placing the casualties on his armored personnel carrier, he proceeded out of the combat zone to an established landing zone. Enroute, an enemy ambush element waylaid the vehicle, wounding all but him and the medic. Sergeant Biggin returned fire, killing one of the enemy, took the driver’s position and drove out of the ambush to the evacuation point. After insuring that the injured were evacuated on the extraction helicopter, he returned to the battle and reorganized his men into an effective fighting force. Platoon Sergeant Biggin’s extraordinary heroism and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
