Both were the ‘right’ guy and ‘right’ eras just now there is more com available to the public - so perhaps there is a chance again - planning, logistics and communucation would be the areas I’d look hard at.
However, it seems to me that most of those sort of guys are busy writing about their machismo to the detriment of any real thought what would actually be involved...
You clearly have not much idea as to the capabilities of army Special Forces. Certainly they have a mission profile that involves "Direct Action." The fabled Studies and Observation Group (SOG) in the Vietnam conflict specialized in that kind of activity. Assassinations, kidnappings, extortion, sabotage, etc. But the reality is, that would be kind of like using a scalpel to mow the lawn. The true mission is raising indigenous armies, training & equipping them to overthrow a sitting government. Do you know that most SOF guys, the real operators, are sergeants?
The makeup of the average Special Forces "A-Team" is composed of ten sergeants usually in the rank of Staff Sergeant or higher. There are ten of these. A 1LT acts as the Executive Officer and a captain is the commander. In certain situations the XO can take command of half the unit and carry out specialized missions. All "A-Team" operators are cross trained in at least one other specialty so that anybody can readily replace a fallen operator in the middle of a mission.
Most have Bachelor level degrees and many have education going far beyond that. All are multilingual. These aren't your average "knuckle dragging" gorilla. They proudly refer to themselves as the quiet professionals simply because they don't spend any time preening and gathering accolades. It's just not in their nature.
The super secret army outfit called in some circles as the "CAG" for Combat Applications Group and in a more formalized title inside the army: Special Forces Operational Detachment Delta. AKA the Delta Force. I think Delta is the "new" SOG. They specialize in so called "Direct Action."
There are thousands of former Special Forces "operators" living quiet civilian lives. I know a few. Trust me, you wouldn't want to get them all riled up for any reason. Remember the mention of how Eric Rudolph managed to run the civilian police ragged trying to hunt him down? He was just a Joe Schmoe infantry private. No special skills and no real experience. How'd you like to have 800 or a thousand combat experienced former A-Team members running around in YOUR backyard looking to cause trouble? Now put all those guys next to the operators from other services like the Navy SEALs and the USMC Force Recon guys. That would be a nightmare for the purveyors of tyranny. IOW, don't be so quick to write these guys off. That's why books are written about their exploits and movies are made....
If they are telling anyone what they are doing or not doing they ain’t......just my opinion.
Stay safe !
