The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Second Lieutenant [then First Sergeant] Jettie Rivers, Jr. (MCSN: 0-1300239), United States Marine Corps, for extraordinary heroism as Company First Sergeant while serving with Company D, First Battalion, Ninth Marines, THIRD Marine Division (Reinforced), Fleet Marine Force, in the Republic of Vietnam on 14 and 15 May 1967. While engaged in search-and-destroy operations against units of the North Vietnamese Army, Company D became engaged with an estimated reinforced enemy company and Second Lieutenant Rivers, a member of the company command group, was wounded. Realizing that the enemy had forced a gap between the command group and one platoon and the two rear platoons, he immediately informed the company commander. At dusk the enemy fire and mortar barrages intensified, and as casualties mounted, the two separate elements set up a hasty perimeter of defense. Second Lieutenant Rivers expertly directed his men’s fire, placed personnel in strategic positions, and personally participated in repelling the enemy assault. Observing a number of enemy soldiers maneuvering toward the perimeter, he mustered a small force of Marines and personally led them to meet the enemy, killing several of the enemy soldiers. When evacuation of the wounded was completed, Second Lieutenant Rivers requested permission to take the point in an attempt to link up the smaller element with the other two platoons. A short distance from the perimeter, the group encountered withering machine-gun fire which instantly killed the platoon sergeant and seriously wounded the platoon leader. Second Lieutenant Rivers immediately took command of the situation, aiding the wounded and personally pinning down the enemy machine gun while the casualties were removed. Now under complete darkness and subject to continuous enemy crossfire and sporadic mortar barrages, Second Lieutenant Rivers assisted in joining the two units. Discovering that all of the platoon leaders had become casualties, he assisted the company commander in setting up an effective perimeter and personally supervised the medical evacuation preparations. Presently a deadly mortar barrage precipitated an all-out enemy assault on the company. Second Lieutenant Rivers was everywhere-encouraging the men, directing fire, assisting the wounded, and distributing ammunition to critical positions. Wounded himself, he continued this pace until late in the afternoon when relief arrived. By his initiative, devotion to duty, and aggressive leadership, he served to inspire all who observed him and was instrumental in saving the lives of many Marines. His great personal valor reflected great credit upon himself, the Marine Corps and the United States Naval Service.
