Shouting
Dont make me laugh - Mil studies, DW!
Most junior officers can just about get away with spelling their own names, let alone pen a well written letter. Most AA will have either done the AACMT pt 1 and/or 2 which gives them a far better understanding of DW, and in my experience the SNCOs do far more admin type stuff than your average junior O anyway.
Getting back to the thread of the topic, that leaves Mil studies. Hmm lets see, by Mil studies what exactly do you study at IOT that you cant pick up from a good book from a good book shop (and a few bad ones no doubt)
Im not trying to down-play the IOT thing, but lets get real, it is a commonly held beleif that AA training is far harder than IOT anyway, a fact born out by the vast majority of AA that are tempted to the dark side!
