I don't think this would have happened in the AF to be honest (to this extent at least). One reason being the AF seemed to do a better job of retention when it came to medical staff, while, IMO, it seemed like many in the medical profession in the Army were there doing their time so the Army would pay for their training/college, and they had no desire to make a career out of the military.
Unlike the Army, a higher percentage of those exposed to combat/extreme conditions are going to be officers and middle-senior NCOs, and you can take it to the bank that this would never have happened to a group of them. Yes, it shouldn't matter if it's an E-2 or an E-6 or an O-1 that is wounded. Of course you wouldn't have large groups, because outside of a base coming under attack, the majority of those in the AF that would be injured would be few since usually you either completed your mission in one piece or you didn't come back.
It's sad, it sucks, and it shouldn't matter, but because the AF was always top-heavy with officers due to the nature of our mission and the fact that most bases were operating around the clock (things never felt like "peacetime" to me), we always seemed to have better facilities.
