Иногда статью по какому-нибудь специфически прикладному вопросу так и тянет классифицировать как funny paper

The science of firearms muzzle flash has been dominated by three perspectives: 1) Does the muzzle flash reveal friendly positions to naked eye observers so as to draw fire from enemy combatants? 2) Can flash signatures be recognized by electronic surveillance with sufficient accuracy to identify source firearms? 3) Is the muzzle flash so bright as to diminish the night vision of friendly forces during a firefight? This paper addresses a fourth question: Does the muzzle flash of a specific cartridge provide sufficient duration and intensity of illumination with visible light to allow observers to positively identify a shooter's face?
