F or conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as a fire team leader
with Company K, in operations against the enemy. L/Cpl. Jimenez' unit came under heavy attack by North Vietnamese soldiers concealed in well camouflaged emplacements. L/Cpl. Jimenez reacted by seizing the initiative and plunging forward toward the enemy positions.
He personally destroyed several enemy personnel and silenced an antiaircraft weapon.
Shouting encouragement to his companions, L/Cpl. Jimenez continued his aggressive forward movement.
He slowly maneuvered to within 10 feet of hostile soldiers who were firing automatic weapons from a trench and, in the face of vicious enemy fire, destroyed the position. Although he was by now the target of concentrated fire from hostile gunners intent upon halting his assault, L/Cpl. Jimenez continued to press forward. As he moved to attack another enemy soldier, he was mortally wounded.

L/Cpl. Jimenez' indomitable courage, aggressive fighting spirit and unfaltering devotion to duty upheld the highest traditions
of the Marine Corps and of the U.S. Naval Service.
