Warrant Officer Carl D. Gray, Vinita, Okla. , from C Troop, 3d Squadron, 17th Cavalry, was piloting LOH over the enemy-infested jungles of War Zone C, 14 miles northwest of Tay Ninh , on a typical early morning reconnaissance for the 1st Brigade. Passing over a stream bed he spotted a figure clad in black pajamas leaning against a tree by the bank. “I called for clearance to open fire and was beginning my gun run when I saw that he was an American,’’ said Gray. 25thida
