This is not movie specific but aimed at all close quarters gun fights against hoardes of zombies/monsters. If one individual of the attacking hoard can be killed by one shot from a pistol, a man standing in a doorway, hallway, or corridor with an assault rifle CANNOT have his position overrun unless his weapon jams or he needs to reload. Secondly, no trained unit is going to allow that man to reload without someone taking his place and returning fire.
Also if a unit has to cross a barrier (like a hedge or something), I'm pretty sure the last man will have someone watching his back as he tries to cross. He won't just turn his back and get attacked by surprise.
Another thing, the conservative use of explosives, poisons, electric shock, etc., against attacking hoardes is inexcusable. (This is why I always choose to use 'special' weapons in video games. If the game gives you a rocket launcher USE THE fukkN ROCKET LAUNCHER.)
when they started the whole "don't feed the animals campaigns." We take it for granted now, but wasn't always like parks are today.
nah nah my fault if I came off like that lol. My uncles all served though and I'm around current and former members of the military 24/7.
