Are there lots of prior Navy in the CG? Are they allowed to keep their rank when they transfer? Which job in the CG involves the most MIO/VBSS? How hard is it to get into a LE Det? I'm a Small Arms Marksmanship Instructor in the Navy, and I'm considering crossing over to the CG if I can't get orders to a command where I'll be doing MIO/VBSS.
