Assault firearms are semi-automatic (firing one bullet per trigger pull) and fully automatic (the weapon will keep on firing as long as the trigger is depressed) anti-personnel rifles, shotguns, and handguns that are designed primarily for military and law enforcement use. With muzzle velocities that are often greater than standard long guns and high-capacity ammunition magazines, assault weapons are built to kill large numbers of human beings quickly and efficiently.
Assault weapons, just like armor-piercing bullets, machine guns, and plastic firearms, are a new topic. The weapons' menacing looks, coupled with the public's confusion over fully automatic machine guns versus semi-automatic assault weapons (anything that looks like a machine gun is assumed to be a machine gun) can only increase the chance of public support for restrictions on these weapons.
Without any practice at all, how long do you think it would take you to quickly empty the 30-round magazine on your .223 sporting rifle/target rifle? Then tell me how much of a disadvantage you are compared with one that is either burst fire or full auto?
Media outlets really seem to be taking advantage of a lack of understanding here.
Been doing my best to correct terminology with people I talk to, but I feel like I'm fighting a losing battle - their minds have been made up, despite my contentions that "assault" is not an adjective, it is a verb. It only became an adjective due to a crappy translation of German.
