THE ONLY LIGHT in the hospital-green back of a Bradley Fighting Vehicle on the move and battened down against the threat of attack is refracted through the dust on the five 6-inch-wide, 2-inch-high periscope windows. But in the gloom you can make out the junk accumulated during five months training in Kuwait and a month of fighting in Iraq: A box of instant grits, spare goggles, a cooler, an Iraqi bayonet, an officer’s laptop, and three precious cans of soda–to be drunk only when the crew are finally on their way home–rearrange themselves as the vehicle stops, starts, and twists with rollercoaster force. And through the periscope ports you can just make out groups of staring pedestrians. The noise of the engines drowns out any conversation not on the intercom. This armored personnel carrier with its deadly 25 mm cannon is part of a task force–a company of armored infantry and a tank company that this morning roared into a Northern Baghdad neighborhood.
