What could go wrong with camouflage? Well, something very specific could go wrong as it turns out. There’s a restriction about camouflage and its uses in the military, specifically within the United States Army. The U.S. Army regulation says wearing camouflage is a no go in any weather situation below -10°F. Evidently, it works too well. The camouflage hides cold-weather injuries (think frostbite).
