A term created for the 1994 "Assault Weapons Ban," which banned firearms based on appearance, brand name, and features not related to firearm function. A proper definition of this word requires the entire 1994 act, so feel free to look it up.
History:

The term "assault weapon" has no industry or military definition. It was created to give a single name to all of the firearms politicians wanted to ban in 1994. Opponents of the 1994 ban refer to it more accurately as the "Semi-Auto" ban.
