You're not picking up what I'm putting down. This is all for informational purposes, but you may wanna refrain from commenting on Air Force shyt if you're unfamiliar with how the AF rolls.
There are almost no specially assigned high-speed support billets like the ones you've mentioned, outside of a few medical ones (including some SOFMEs). Remember, most AF personnel don't even maintain weapons quals year round: TACP/ALO, SOWT/SR, CCT/STO, PJ/CRO, SF, and perhaps EOD are exceptions to this. The AF, even AFSOC, is not the Marines where everyone is a rifleman first and a cook or band member second.
The percentage of the career fields we're talking about is so small it would be pointless to discuss it in this context; unless somebody ITT ends up at one of a handful of AF bases, they wouldn't even be part of those units.
Furthermore, a lot of that is again redundant. You don't need an SF cook if you're being assigned to a Ranger unit that already has cooks (Ranger TACP). You prolly don't even need a SOF medic if you're already bringing a PJ who has those same SABC capabilities. Those physical therapists aren't going outside the wire; the medical folks involved in PR and CASEVAC are specially trained but are not SOF like that (research CCATT and you'll see regular ass people, not operators).
Security Forces has selections for a few different billets similar to 'enabler selection', but a new airman would not get selected right out of tech school to go do DAGRE or the like (you'd have to prove you're squared away and can actually do your job before they'd let you try).
^This should be common knowledge to anyone in the AF and isn't guarded knowledge. I've also been part of AFSOC units, and I'm certainly not finna be kicking down doors nor did I go to Airborne training.
The question about fatbodies is already answered because the fat fukks stay home while the Special Tactics guys go do their thing; they aren't sitting there rucking in an undisclosed location.
