United States Army

Sean Baker, a native of Lawrenceburg, Kentucky, is a United States Air Force veteran and former member of the Kentucky National Guard, who served during the first Gulf War, and as a member of the 438th Military Police at Guantanamo Bay.

In January 2003, Baker was ordered by an officer at Guantanamo to pretend to be a prisoner in a training drill. As per instruction, Baker wore an orange prison jumpsuit over his uniform and crawled under a bunk in a cell, so an "internal reaction force" consisting of four (possibly five) US soldiers could practice extracting an uncooperative inmate from his cell. The soldiers in the reaction force were operating under the impression that he was a genuine detainee that had assaulted a sergeant.
