What would happen if a A330 of a civilian airline had the similar incident. I suspect the captain would be lucky if he ever flew an aircraft again or even a desk. If the airline did not sort it out then the regulator may step in, and also imagine the passengers response to the captain's brief once they recognised his name. Not many would fly with that airline again.
You'll generally find (decent UK airlines) that if the culprit put his hands up straight away, the outcome will be proportionate. Depending on the type of incident, it can range from a quiet word post ASR through an interview (hat on variety) to retraining and possible loss of command.
The front door generally only appears in the process if anyone has tried to cover anything up or for extreme stupidity. Even then, there is generally an invitation to open the front door for yourself first.
