Article Photos: General's battle with PTSD leads him to the brink 2/5

In this undated photo provided by Maj. Gen. John Cantwell, front, the general walks along with other soldiers in Tarin Kot, Afghanistan. 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
