What happens if an ordinary soldier without connections fails to return from leave

If you were a kid without any connections, you son of a bitch, are you freaking crazy wanting to go to the stockade? Get your ass back here right now, you piece of shit. Are you trying to kill me? You little bastard. Don't give me that bullshit about needing surgery; just get back here. If you come back, you're dead~~~ Get back here immediately, you bitch!
And once you're in, I don't give a damn if you're hurting, you'll just get hit with a shot. You're going to get chewed out like crazy.
