Fooey. And here I was thinking this was going to be about not sillouhuetting your profile along a hill side or a wall, picking a hide that would not be an obvious hide position if you were the enemy looking for your hide. Using things like netting to mask your image inside a room, knocking holes through walls to shoot through instead of sticking your pumpkin head up above a wall like a do do bird. Covering your rifle and helmet head so they look more like objects in nature and not obvious helmets and rifles. General basic stuff like that. We are stuck on the forward roll for some reason as the only maneuver or the perfect maneuver or something. It works a lot in Hollywood fights so it must be great.
One of the phases of my training was in judo type moves and the forward roll is a basic judo and jiu jitsu move. For the proper way to execute this look up the word Ukemi. You never roll directly over your spine.
