Well....as far as I can tell this year is supposed to start the regulations that allow transgender service members to transition while on active duty. Unfortunately I don't know when they begin, and in what branches it is being instituted. I am also fairly certain that certain MoS's will not allow certain genders to serve in that capacity, but this may be going away.
As to your specific command, I would suggest going to your Squad Leader, LT, or Cpt. and talk with them about your situation. Maybe involve a chaplain, and possibly your therapist. Do you use a Military Therapist? According to the last regulation I read on the subject, they can't discharge you or hold this against you, but they could make you choose between transitioning and service.
Again the regulations are supposed to be changing/have changed to allow it, I just don't know when they were to start.
