Would it be feasible if we do what what the USA ROTC program whereby formalise the UOTC, URNU and UAS as when you;ve graduated from uni and done the required training weekends, summer camps, specialist courses and get a reserve commission (in TA its 3 weeks at Sandhurst for the commissioning course) then transfer to regular commission.
But then again our system of having to go through OASC, AIB, AOSB then Cranwell for half a year, Dartmouth and Sandhurst for a year has ben working for the last century or so.
IIRC majority of the officer corps in the USAF, USA, USN, USMC are ROTC graduates as opposed to Colorado Springs, West Point, Annapolis.
