Anyway, the video demonstrates one of the major idiosyncrasies of Star Trek. It has to do with those phasers. Formidable weapons, yes? Depending on the settings, they can stun, kill, or even vaporize large objects in a matter of tenths of seconds. They come in convenient hand-held, and incredibly powerful starship-sized varieties. According to the manual, they are a directed energy weapon (no messy projectiles like bullets required) emitting "nadion" particle beams.
