The battlefield isn't a workplace, and taking a lunch break is almost a criminal luxury for soldiers who carry their heads strapped to their belts. You see, during intense combat, all physiological activities—sleeping, eating, urination—must give way to fighting. Peeing in one's trousers and holding in a bowel movement for an entire day are, indeed, no exaggeration. Even during the trench standoff phase, going to the bathroom requires a group outing, partly to prevent peeping (in a thick fog) and partly to guard against enemy scouts. Getting captured with your pants down or stepping on a booby trap while squatting is just too stupid, no matter how you think about it. To avoid such situations and allow your comrades to relieve themselves peacefully, it is all too common to stand guard at the restroom door with a rifle slung over your shoulder and a grenade tucked in your belt.
