Article Photos: General's battle with PTSD leads him to the brink 4/5

In this undated photo provided by Maj. Gen. John Cantwell, left, the general talks with an unidentified injured man at an undisclosed location in Afghanistan. Cantwell could see the ridges and calluses of the skin, and the pile of desert sand that had swallowed the rest of the Iraqi soldier. The troops Cantwell was fighting alongside in the Gulf War had used bulldozing tanks to bury the man alive. This hand - so jarringly human amid the cold mechanics of bombs and anonymous enemies - was about to wedge itself, the Australian man would write decades later, "like a splinter under the skin of my soul." It would lead, along with other battlefield horrors, to the splintering of his mind and to a locked psychiatric ward. (AP Photo/Maj. Gen. John Cantwell, Sergeant Neil Ruskin) EDITORIAL USE ONLY
