U.S. Army Patrols Baghdad Neighborhoods

BAGHDAD, IRAQ - AUGUST 17: A soldier takes a retina scan during a census mission with the U.S. Army Delta Company 212 Cavalry in the Ghazaliya neighborhood, which has been used as a base for Sunni insurgents, August 17, 2007 in Baghdad, Iraq. During census missions all males between 15 and 55 have their retinas scanned, are fingerprinted and have personal information gathered for a database. Violence in the neighborhood has abated somewhat since the Army set up a Joint Security Station (JSS) with the Iraqi Army. (Photo by Spencer Platt/Getty Images)
