FILE - In this Saturday, Sept. 19, 2009 file photo, U.S. Army Sgt. German Gomez, 23, from Houston, Texas, of the 118th Military Police Co., based at Fort Bragg, N.C., stands guard during a training session for Afghanistan National Police at their combat outpost in the Jalrez Valley in Afghanistan's Wardak Province. Hundreds of soldiers have been detained or removed from the Afghan National Army in 2012 after a surge in insider attacks against foreign forces who are their supposed partners in the fight against Taliban insurgents and other militants. The Afghan officials say they are re-vetting soldiers to stem the attacks that threaten to unravel the international community's alliance with the fragile government trying to stand on its own as foreign troops withdraw.(AP Photo/Maya Alleruzzo, File)
