maybe NEM will see MS officers chopped at the end of the level 9 year as a new method of outflow!?
I've definitely seen a Powerpoint slide somewhere that shows promotion to Sqn Ldr giving service to 38, Wg Cdr to 44, and Gp Capt to 55. Up or out... can't remember what the 'codename' for it is, but it's on the table somewhere!
