Hi Scraggle,
Good advice from Blacksheep.
The justice system works the opposite way round in the Forces, you are "Guilty" until you can prove your innocence.
Gone are the days where you were marched in, grilled until you admitted everything, thanked your lucky stars you only got six months in Colchester for breathing out of turn.
Depends what your are accused of, and what evidence you are allowed to produce, but a good lawyer will be invaluble.
Good Luck and let us know what happens.
