Well, there isn't really a 'retire' move, other than being an advance in the direction other than toward the enemy. It is use of English, not a description of a specific manoeuvre. So, you 'retire' by moving away from the enemy. You can't move 'closer' to the enemy without making a CMT... which is difficult enough but even harder for a fragged unit. So, basically a heavy foot BG (for example) would have to turn around one turn, and then move away from the enemy in the next turn (if they are still alive).

I think so, so long as they pass the CMT. I don't have my rules handy, but I think you're right yes.

Well, that's one option... the other option would be to expose thy rear with some nice friends in between
