There should only be one legal system to make rulings, nothing secret, nothing private. The only exception is that private councils or mediators should be opt-out, no strings attached, no questions asked, in order to easily gain access to a real court. This may be unpopular, and I've never been part of the military, so I don't know the drill there, but just as secret courts for the likes of Snowden, there is no place for a military tribunal. And just like a normal court has to rule on parking tickets and serial murders, it shall also rule on war crimes. Think Den Hague as somewhat of an example. I'm perhaps repeating myself, but a secret court nobody can discuss, attend or scrutinize, does not exist in the real world and is something else misusing the existing name (court). I think of it as good marketing for a system that wants to get rid of dissidents and is basically no different than any other show trial under dictatorships. If you cannot defend yourself properly, it's not a trial. If you're sure you're in the right, you have no justification to hide behind closed doors whose existence is denied as well.
