The President of the United States of America, authorized by Act of Congress, July 9, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Distinguished Service Cross to Captain (Infantry) Clyde J. Sincere, Jr., United States Army, for extraordinary heroism in connection with military operations involving conflict with an armed hostile force in the Republic of Vietnam, while serving with Company B, 5th Special Forces Group (Airborne), 1st Special Forces. Captain Sincere distinguished himself by exceptionally valorous actions during the period 8 through 11 November 1966, while serving as Special Forces Senior Advisor to a Vietnamese Company engaged in search and destroy operations near Plei Trap. On 8 November, Captain Sincere personally led his forward element in an attack on two anti-aircraft guns. His men killed four insurgents, and captured their weapons and 35 packs of information concerning future enemy operations. On the night of 10 November, while Captain Sincere was separated from his company, it received an attack from a large Viet Cong force. When the acting commander was seriously wounded, and the unit’s ammunition was nearly exhausted, Captain Sincere flew into the ravaged landing zone to bring supplies and to lead the force out of the enemy circle. He jumped from the helicopter before it touched down and fearlessly ran, through a tremendous outburst of fire, toward the nearest cover. Insurgents hidden at this position wounded him, but he was able to evade further fire and reached his own lines. Captain Sincere took command of the defenses, and again entered the bullet-swept field with a small group to retrieve the critical supplies. Upon returning to his own lines, he distributed the ammunition, called in air and artillery strikes, and enabled the company to break contact with the Viet Cong the next day. His fearless actions under intense hostile fire gave his men the leadership and inspiration to work as an effective fighting force. Captain Sincere’s extraordinary heroism and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, and the United States Army.
