Story time, boys and girls.

When I joined the Army and went to basic training, one of the first things they did was show us how to stand at attention, at-ease, right face, left face, and about face. Then they turned the training unit and marched off.

And then stopped and screamed at us for marching like Nazis.

Turns out, you don't see US soldiers marching like that because it's stupid as hell, and you can't do it for twenty miles with a rucksack. The US military for all their many, many faults, is real good at war, and marching like a toy soldier doesn't help you do war.

So we learned how to march like Americans, which is much more casual. The only thing you've gotta do is make sure you match the stride length of the soldier in front of you, but even that is more of a suggestion than a hard rule. We got good, though, because we were assholes.

We would ease out behind someone who was walking somewhere and roughly the same height, and step slightly faster than the person in front of us, until we were close behind them. Then you perform a little skip at the last second to get back to the same stride and close the last few inches. The end result is that your chest is hovering about an inch from their back, your nose is an inch from the back of their head, and your hands are swinging right behind theirs. While walking at full speed.

You haven't had a jump scare until you've marched two blocks, turned your head, and glimpsed someone's face an inch from your own.
