Regarding fences. In Israel, high quality fences were shown to be practically impenetrable. Except by trained and sophisticated soldiers of Hamas, different story!).

On the border with Egypt, there used to be thousands crossings. The fence took it down to ~10/year or less. In other 3 directions, too , Israel built fences that are pretty much blocking passage. 

Is Poland's "border wall" isn't working, it's because it's not well built enough. And I understand the forest issues. Still decent walls can be built. And you install cameras and sensors and it's pretty reliable. 

those conspiracies don't work most of the time "you can only keep a secret between two people, provided one of them is dead".

the personal risk for anyone involved + the human psychological tendency to chat and to have a hard time holding on to immortal secrets mean it's usually irrational for both organisations to do intentional cheating. 

wow. nice post. and respect!

I do not think FoI requests apply for classified military studies

Polyphasic is useless for the military IMHO.

Its not flexible. Pilots are less useful if they must be sleeping on multiple rigid times.

Its risky. Because if you lose a nap you are fucked. And this is exactly the type of screw-up the military likes least. You train people to stay functional under duress. Not to be germless lab pigs that fall like a feather missing a nap.
