I don't know what the standard procedure is, but it would probably depend on the branch of service and whether or not the person is enlisted or an officer.

I know of two different situations where the people commited the same crime and received different punishments. One, a Navy Petty Ofcr 1st Class, got thrown in the brig overnight, had to appear in military court. Since he got caught driving off base, he also had to go through punishment through District Court -- 14 week alcohol assessment class, suspension of license for a year, and a hefty fine.

Another friend, a LT, was demoted and had to attend a special alcohol education class on base in addition to the punishments he received through District Court.
