Assault rifles are most commonly defined as fully-automatic rifles firing intermediate rounds, that is, bullets sized in-between those of a pistol (which in a full-auto long arm would be a submachine gun) and "full-size" rifle cartridges (which would be a battle rifle or larger). Though a relatively new concept compared to other firearm classifications - the first weapon to fit all of the stipulations (and the one for which the name "assault rifle" was coined) came about during World War II, and weapons with similar capabilities only date back about 20 years earlier - they have quickly become the most common weapon among armed forces for their balance of power, range, and utility compared to most other weapon types.
