Air Forces Special Operations Units

Due to my unemployed state I’ve been working on my book more than normal. But I need a little help. For aircraft and army units its easy to find what I need but I can’t get much information on ground forces attached to various Air Forces. I’m just trying to pick some reasonable antagonists since due to the plot the countries involved havent been chosen yet. I need some proper combat units, not groups like the USAF PJs or more conventional units like the RAF Regiment. I’m looking for units in a similar vein to the way US Navy has the SEALs. Its just to provide some different antagonists than you normally find in novels and films because the British Parachute Regiments Pathfinder Platoon are already included. I’m trying to make it as realistic equipment, units and tactically accurate as possible. I know we are oriented to stuff with engines but I was hoping a few of you know some of the different units incorporated into your airforces. This is an Air Force discussion forum so a discussion of things other than aircraft should be included anyway. If you do well I may start naming a few characters after you 😀
