I kinda like detachment B-52 of Delta. Something about resorting to treating special-operators like a triple slung load under a huey and the unfortunate consequences when the cargo doesn't quite make it into the straps.
(or the whole list of everything that can go wrong)
Projects Gamma (B-57)* and Sigma (Bravo-5-6)** were also things.
Also, hardest moment to watch of BAT*21:
"I say again, is it the pilot?"
*In 1969, the intellegence-gathering network had been compromised, extensive burn-notice throughout Cambodia... huge rescue-affair and assasination mission ensued. Buzzword that followed in a Senate inquiry: "Terminate with extreme prejudice" / "You have failed me for the last time" > You are in command,
Admiral.
Then there's the "Regional/Popular Forces" AKA: "Ruff-Puffs", ARVN militia. Mid-war,
the USMC tended to implement a few men per platoon with some success. Despite the average grunt only recieving ten days of training in the vietnamese language (causing
plenty of communication barriers, amonst other problems).
-PFs were intended to be purely defensive, having some sort of occupation precluding them from actual deployment, but trained more-or-less as minutemen. This changed for the worse towards the end of the war.
-RFs were closer to 3rd-line national-gaurd with WW2 era equipment and scavenged stuff, patroling rear areas "of strategic importance" (such as some wealthy landowner rubber-plantation).
How they were treated by the VC is pretty straightforward.
