Getting “busted down to black sleeves”, or reduced in rank to Recruit, isn’t the career killer for Orions that it would be in most Terran militaries.

The individual has to pass Basic Training again, but given that they still possess their education and training, they should rise fairly quickly to their level of competence. It is not uncommon for service members to reach a higher rank than before.

However, member of the Imperial family are prone to being invited to explore other trades when they screw up that badly.
