CAMP LEJEUNE, N.C. — A Marine who pleaded guilty Wednesday to urinating on a dead Taliban fighter in ­Afghanistan will probably be demoted one rank under a plea agreement, although a military judge called for a much harsher sentence.

Staff Sergeant Edward W. Deptola pleaded guilty to multiple charges at court-martial, including dereliction of duty for desecrating remains, posing for photographs with corpses, and failing to properly supervise junior Marines.
