Spc. Brandon Trentham, Bravo Co., 1-17 Infantry, prepares to leave COB Outlaw in the Argandab valley in Kandahar, Afghanistan. The company generally rotates out to another FOB a kilometer away every five days, always on foot. He estimates that his bag weighs around 50 lbs. - and with his 240 and body armor, he's probably carrying at least his body weight in gear. "You kinda get used to it," he said.
