In this May 20, 2010 photo, U.S. Army Stryker vehicles kick up dust as they roll across a rocky road to pick up troops from Charlie Company, 1st Battalion, 17th Infantry Regiment of the 5th Stryker Brigade who were on patrol in the Shah Wali Kot district of Afghanistan's Kandahar province. Twenty-two men in the U.S. Army's 1st Battalion, 17th Infantry Regiment of 800 died in a yearlong Afghan tour ending this summer. Most were killed last year in the Arghandab, a gateway to the southern city of Kandahar. About 70 were injured, all but two in bomb blasts. (AP Photo/Julie Jacobson)
