> Is there data on how much real service one might be doing?
Not really ‘data’ but the last time I was in a combat zone there were mortars/rockets flying in on a daily basis, usually around chow time.
Also ‘safe’ jobs weren’t a guarantee. We were going out on a convoy mission and the reservists unit escorting us was short handed so just found a warm body to ride in the gun truck in the form of an office girl in the Air Force who had been in country three weeks and probably hadn’t touched a weapon since basic training.
Mission takes priority and if you need a body you find a body.
Also my last ‘real’ deployment was in a reserve unit and I wouldn’t recommend that to anyone. Zero discipline and we were a transportation unit so mobile enough to get into all sorts of trouble. We got out of there before things got really bad (our mission was over so they just sent us home) so there’s that.
