The President of the United States of America takes pleasure in presenting the Silver Star to Lieutenant Robert MacQueen Ballinger, United States Navy, for conspicuous gallantry and intrepidity on the morning of 23 September 1964 in action against enemy aggressor forces while serving as Advisor to the 21st River Assault Group, Vietnamese Navy. When the boats of his assault group were subjected to intense automatic weapons and recoilless rifle fire from a Viet Cong force hidden along both sides of the Ben Tre River in Kien Hoa Province, Lieutenant Ballinger promptly and skillfully manned and operated an 81-mm. mortar, delivered accurate and devastating fire on the enemy positions. Following his example, the assault group brought all their fire to bear on the Viet Cong and succeeded in routing the attackers and inflicting numerous casualties. By his outstanding leadership and cool courage in the face of hostile fire, Lieutenant Ballinger upheld the highest traditions of the United States Naval Service.
