On Jan. 7, someone strolled into a supply room at Camp Eggers, a coalition base near the U.S. embassy in downtown Kabul, pocketed two sets of car keys and walked out undetected. Sometime over the next 24 hours, the thieves drove away with two black-painted, armored Toyota Land Cruisers belonging to the U.S. Army’s 26th Maneuver Enhancement Brigade, a unit that escorts coalition personnel around Kabul.
