I was a Security Policeman many many many many years ago. I recall I recall going to work (this is no Korea), you got you thermal underwear, fatigues, field jacket liner, flack vest, parka, furlined flightpants on. You get on post and then..ya gotta take a whiz...this is where you find out just how good a "shot" you are.
This was something they never covered in Security Police school.
This is true. You've got to consider the "shrinkage factor" too.
