As a point of real-world reference for "military prisons," Leavenworth is where most of the notorious spies are held, regardless of whether they were John Walker (USN) or Aldritch Ames (CIA). As a secondary point, MCAS Miramar also holds a high security "military" prison that regularly gets used for certain non-military convictees and as a ICE transfer point on the way to deportation, as well as military courts martial convictees.
As to Madcap? Whose that below the mask? Are we sure that it's the same person a Assault? (When "cops 'n robbers" rules apply, else, yes, he'd have a shitload of police assault, accessory to, and conspiracy to charges.)
