Likely you're not playing at all, but are a true right wing idiot.
You nitwits have been asking th esame brainless question for weeks. A definition is easily found, yet you nitwits pretend it's a hard thing to identify.
It isn't. You're an idiot.
""An assault rifle is a selective fire (either fully automatic and/or burst, and semi-automatic as well) rifle that uses an intermediate cartridge and a detachable magazine. It should be distinguished from the US legal term assault weapons. Assault rifles are the standard service rifles in most modern armies. Assault rifles are categorized in terms of using an intermediate cartridge power that is between light machine guns firing full power cartridges, which are intended more for sustained automatic fire in a light support role, and submachine guns, which fire a lower powered pistol cartridge rather than a rifle cartridge. Fully automatic fire refers to an ability for a rifle to fire continuously until the magazine is empty and no rounds remain; "burst-capable" fire refers to an ability of a rifle to fire a small yet fixed multiple number of rounds with but one press of the trigger; in contrast, semi-automatic refers to an ability to fire but one round per press of a trigger. The presence of selective fire modes on assault rifles permits more efficient use of rounds to be fired for specific needs, versus having but a single mode of operation, such as fully automatic, thereby conserving ammunition while maximizing on-target accuracy and effectiveness.""
What is an "assault" rifle?
Children's descriptions don't count. Neither do Diane Feinstein's.
