For heroism in connection with military operations against a hostile force: Captain Casey distinguished himself by heroic actions on 3 September 1969, while serving as the S-3 Officer with Headquarters and Headquarters Company, 2nd Battalion, 22nd Infantry in the Republic of Vietnam. When elements of Company C came in contact with a large enemy force, Captain Casey was flying over the action in an observation helicopter. As the battle progressed, effective leadership was needed by the ground unit. Immediately, Captain Casey directed his pilot to land in the battle area. Having assumed command of the company, Captain Casey quickly reorganized the element and directed evacuated of the wounded men. With complete disregard for his own safety, Captain Casey exposed himself to the hail of fire as he led his men in an assault on the enemy stronghold. His valorous actions contributed immeasurably to the success of the mission and the thwarting of the hostile force. Captain Casey’s bravery and devotion to duty are in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit, the 25th Infantry Division and the United States Army.
