RALEIGH, N.C. (AP) — Prosecutors argue that serious injuries to two soldiers who searched for Army Sgt. Bowe Bergdahl in 2009 show that he endangered his comrades by leaving his post in Afghanistan.

The motion filed this month lays out how prosecutors plan to tie the injuries into arguments that Bergdahl is guilty of misbehavior before the enemy. It’s a relatively rare charge that carries up to a life sentence.

One of the soldiers suffered brain injuries when he was shot in the head and uses a wheelchair now.

Defense attorneys, meanwhile, filed a separate motion on Wednesday arguing that the general overseeing the case has had improper contact with prosecutors rather than relying on an intermediary.
