BAGHDAD, Iraq (CNN) -- Army Staff Sgt. Antonio Gonzales points his weapon across the Tigris River, keeping a close eye on a bridge that was cracked in half by an insurgent attack a few months ago.
He's 31 and on his second tour in Iraq. His survival and that of the men he serves with rely on an instinctive ability to spot hidden threats. A pile of trash, an odd formation of wires, a cart seemingly left innocently by the side of the road -- all could mean death.
"If you don't come out here, then you really have no clue," says Gonzales, a member of Task Force Justice, which is operating in northern Baghdad. "They don't understand what it is driving down the road and to wonder if you are going to get blown up or not."
