What are mentors? Who assigns them? Are inter-flotilla and/or division training allowed, and if so, who are the mentors?

The flotilla commanders or their designee (FSO -MT or FSO-OP ) assign mentors to trainees. If inter-flotilla and/or division training is offered with mentors from other flotillas, the flotilla commanders (FC 's) need to give their approval of the mentors who will be signing off their members. This keeps the FC's "in the loop" in knowing who is signing off their member
