Investigation initiated following discovery of a CD during an office clean-up in Afghanistan, containing numerous pictures of American soldiers posing with pistols and M-4 rifles pointed at the heads and backs of hooded and bound detainees. The photographs were taken by a number of soldiers from the Second Platoon of the 22nd Infantry Battalion while stationed at Fire Base Tycze, Dae Rah Wod. Numerous soldiers admitted to posing in the pictures and taking and downloading the photographs as "mementos" of their time in Afghanistan. The investigation found probable cause to believe that eight soldiers committed the offense of Dereliction of Duty, but not the more serious charge of Aggravated Assault. Most of the soldiers interviewed stated that they were not aware of any set policy on the treatment of detainees, and did not realize at the time that their actions were wrong. A sergeant stated that he had also seen pictures on Army computers of detainees being kicked, hit or inhumanely treated while in U.S. custody. The photographs also included pictures of soldiers "PUC'ing" (Person Under Control) each other, a platoon ritual in which soldiers would be bound and hooded like detainees by other platoon members, and have water thrown on them.
