The closets Work of fiction I can think of that might have recreations of such training is "The Unit" It's produced by a Former Delta operator.
Okay Let's Play.
First the ground work. seeking a place too begin I would start in the Lanzhou Military Region looking for a Facility pretty much in the middle of Nowhere. I would be wanting access too the local Garrison for use in qualifications and a limited Role in training. Now Comes my first Draft, A officer in charge. I call in Officers known for being trouble shooters and good too there men. My Draft pick though must pass a bit of a Sun Tzu riddle.
I sit him down in my office and Tell Him I have a very special mission for him.
I want him too deliver a High priority package by hand, Too a Office in Taipei City. He and his unit will be air dropped into the Ocean near his destination via Y8 transport they will swim into the bay avoiding hostile patrols Infiltrate the city and make there way on foot to there destination.
Then I ask him if he has any thoughts.
If he Grins and Asks When He leaves... He's not getting the job.
If he looks at me and tells me I am an Idiot.
I think I have my man.
I ask him then how he would deliver this package. If his answer is something simple like dress as a civilian, Disguise the package as luggage and use a Regular flight too land in the city.
He just got Hired.
covert SF when they do the Job right are never heard of. When they screw up they get all the press they never wanted. PR people might want too bring them out but Covert units prefer the shadows
Now My chosen officer takes the Hot seat. His mission is too run my unit too act as recruiter and begin training.
Recruits: NCO's are my priority, People who Think for themselves and are mature enough too know what works and what does not most SF units pic Sargent and Life long Enlisted guys who will be in service a long time and will use What they are about too learn.
Selection will be hard oriented too individuals A basic PT test field marches under particular conditions rifle qual, and navigation exercises.
The last part last but not least, the most difficult of it all A gauntlet. Remember my location? A field navigation exercise I drop my recruits into the desert at night each on his own with a few days rations a basic field kit, a destination a map a compass a secret pass code and a warning one week they have a week and eight nights too avoid capture if they fail things will not be pleasant. the next morning at dawn I let my hounds out the local garrison with orders not too kill but too hunt and capture Non lethal force is allowed and a little rough treatment okay. those captured before six days are up will be subject too interrogation. If they give the pass code they are out. If they hold out or are not captured they are in.
