The one I have always assumed is Maniac could be Angel or Hunter, its impossible to tell as the resolution is so small, plus there are extra wing pilots in the briefing room, it might be one of the other wings? When you pick into it, it wouldn't make a whole lot of sense for characters to be in the rec room for you to talk to, then immediately asleep in the barracks.
Its interesting that on Academy TV the cadets have individual or double berths, there is no barracks that we see; maybe its a bit like the local fire station where the beds are for wings that are 'on call' as first response (If you were under attack, presumably you'd get up and get to your fighter, instead of pulling a 'Flash', but it'd take time if you are off duty in the berths)
