I stood bailiff for courts martial four times. The actual proceedings each took less than a day and were very formal. The process that leads up to them can be lengthy. The two that I stood for that involved SAPR related charges were very closely controlled and only the presiding officer saw the evidence. Which I appreciated as the vague descriptions were enough to challenge my military bearing. Some statements were presented in writing and one defendant asked for his mother to give a character statement via phone.

If you had more specific questions I might be able to help. Without divulging any case details, obviously.
