Three. That’s how many times Sgt. 1st Class Alwyn C. Cashe entered the burning carcass of his Bradley Fighting Vehicle after it struck an improvised explosive device in the Iraqi province of Salahuddin on Oct. 17, 2005. Cashe, a 35-year-old Gulf War vet on his second combat deployment to Iraq since the 2003 invasion, had been in the gun turret when the IED went off below the vehicle, immediately killing the squad’s translator and rupturing the fuel cell. By the time the Bradley rolled to a stop, it was fully engulfed in flames. The crackle of incoming gunfire followed. It was a complex ambush.
