If anyone could shed some light for me, I just want to confirm that I am on the right track here. So YO's are recruited, in September, and commissioned (IC) as a 2Lt from day one. Phase one then lasts 15.5 (or 15?) months (attaining the Green Lid 32 weeks into 15 months?) before being appointed Troop Commander. Troop commander for 12 months is Phase 2 After this, Officer is promoted to Lt and is now free to specialise. 3 Years as a Lt, and the Officer is promoted to Capt (without exception?) This is the rank most Officers leave the RM at. How many years served as a Capt (minimum) are required to qualify to be promoted to Major? If the YO has not dropped out in the first 6 months(with 14 days notice) then the minimim Return of Service is up to the time of Captain promotion. So ROS = 5 years ish (+ 3 months, 15months P1 2Lt, 12months P2 2Lt, 3 years as Lt )? Is this the right of it? Thanks alot in advance for any advice you can give me.
