For conspicuous gallantry and intrepidity at the risk of life above and beyond the call of duty. As a platoon leader in the 1st Cavalry Division (Airmobile), 1st Lt. Marm demonstrated indomitable courage during a combat operation. His company was moving through the valley to relieve a friendly unit surrounded by an enemy force of estimated regimental size. 1st Lt. Marm led his platoon through withering fire until they were finally forced to take cover. Realizing that his platoon could not hold very long, and seeing four enemy soldiers moving into his position, he moved quickly under heavy fire and annihilated all 4. Then, seeing that his platoon was receiving intense fire from a concealed machine gun, he deliberately exposed himself to draw its fire. Thus locating its position, he attempted to destroy it with an antitank weapon. Although he inflicted casualties, the weapon did not silence the enemy fire. Quickly, disregarding the intense fire directed on him and his platoon, he charged 30 meters across open ground, and hurled grenades into the enemy position, killing some of the 8 insurgents manning it. Although severely wounded, when his grenades were expended, armed with only a rifle, he continued the momentum of his assault on the position and killed the remainder. His selfless actions reduced the fire on his platoon, broke the enemy assault, and rallied his unit to continue toward the accomplishment of this mission. 1st Lt. Marm's gallantry on the battlefield and his extraordinary intrepidity at the risk of his life are in the highest traditions of the U.S. Army and reflect great credit upon himself and the Armed Forces of his country.
