It was astonishing how quickly we reached a state of "bored adrenaline". By the second day, we were preparing our breakfast and not even looking outside when we heard (real) gunfire or airsoft pellets striking our shack. I remember sitting down, very tired and bored, thinking about nothing, but my hands still trembling from the adrenaline.
The ways that I naturally felt like moving (I think I'll lean on the wall of this shack for a while and watch the street, I think I'll lean against the wall and keep a hand on my gun) I eventually realized were the same poses I've seen civilians take in pictures of war zones.
That is, perhaps, the hedonic treadmill [1].
What a privilege to live in a stable part of the world!
It's no privilege: if these pictures show us one thing is that it was a hard earned right. These men paid the price. Freedom is never granted, it is earned.
