"For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty, Sergeant Charles C. Fleek distinguished himself while serving as a squad leader in Company C, 1st Battalion, 27th Infantry, 25th Infantry Division, on 27 May 1969 during an ambush operation in Binh Duong Province, Republic of Vietnam.  Sergeant Fleek's unit was deployed in ambush locations when a large enemy force approached the position.  Suddenly, the  leading enemy element, sensing the ambush, halted, and started to withdraw.  Reacting instantly, Sergeant Fleek opened fire and directed the effective fire of his men upon upon the numerically superior force.  During the fierce battle that followed, an enemy soldier threw a grenade into the squad position.  Realizing that his men had not seen the grenade, Sergeant Fleek, although in a position to seek cover, shouted a warning to his comrades and and threw himself onto the grenade, absorbing its blast.  His gallant action undoubtedly saved the lives or prevented the injury of at least eight of his fellow soldiers.  Sergeant Fleek's gallantry and willing self sacrifice were in keeping with the highest traditions of the military service and reflect great credit to himself, his unit, and the United States Army."
