Hello X, I'm not a frequent user of this cite but I thought you fellas would gat a kick out of this! Okay context: Both of my parents where in the military. Both were well respected and highly experienced. Sometimes my dad would let slip his knowledge of 'Military secrets' like one time we were taking care of a neighbor's dog and my dumb ass somehow managed to leave the key on the inside of the door and lock myself out. so my Dad hops over and pics the lock. He told me never to tell anyone because he learned it in the special forces or something. he later on a drive one night told me that he was an honorary member of a club that I'm not allowed to know the name of. these events sparked my curiosity for years. sometimes when a little tipsy he would tell me more. 
(Sorry for long context)
I can't remember what it was sparked by but one day we got into the topic of 'Secret battlefield Healing techniques' I asked Him to elaborate and all he would say was 'Well you know how you can tell someone is watching you even if you can't see them?'. he would not explain the correlation and refused to elaborate further. You guys have any clue how those two concepts connect? I've been wondering for years. 
Pic unrelated sorry.

>'Well you know how you can tell someone is watching you even if you can't see them?'

This comes from the unease in ccertain cituations, soilders (especially good ones) are taught to sniff out certain scenarios where enemies could be hiding. Ive read through my great grandad's journal (Im a bit of a historian and he fought in WW2) and most 'gut instincts' come from stuff that just feels off, couple with military training. See an empty road in enemy territory with no barracades? Shits gotta be filled with landmines and vehicle traps, that or its an open door to an ambush. See a broken branch is woods you havent been? You have someone watching you. Even after war, these soilders remember techiques they used as a 'third eye' that alerts them to danger. 

Grandfather (who served in Veitnam) always would sit next to a wall, so no one could sneek up on his blind spot. He hated leaves with a passion (as they were used to cover spike pits) and would rake up every single one from his lawn. They still have that shit engrained in their muscle memory, its not a stretch to think they have a handle on combat scinarios.
