Camp Pendleton, California (CNN) -- A U.S. military judge sentenced a Marine squad leader charged with alleged war crimes in Iraq to a maximum of 90 days in prison and a reduction in pay and rank. But because of a plea deal with prosecutors, Staff Sgt. Frank G. Wuterich won't serve any time in the brig. The military judge was obligated to abide by the plea arrangement between prosecutors and the defense. In the end, Wuterich's sentence amounts to a reduction in rank -- to private -- and a pay cut. A final adjudication will be made by Lt. Gen. Thomas Waldhauser, commander of Marine Corps Forces Central Command, but he cannot increase Tuesday's sentence, a Marine spokesman said. The commander can reduce it, though, the spokesman said.
