A [b]submachine gun[/b] or SMG is a carbine-length, pistol-caliber [[gun|firearm]] that is capable of fully automatic fire. Early SMGs such as the [[MP18]] have rifle-like appearance. While more modern models do have features like [[folding stock]], pistol grip and a fire selector. The term "submachine gun" was coined by [[Thompson submachine gun|John T. Thompson]], to describe its design concept as an automatic [[weapon]] with notably less firepower than a [[machine gun]] (hence the prefix "sub-"). 

A subset of submachine gun is dubbed [b]machine pistol[/b], which are often used to describe a handgun with automatic fire capability (e.g. Glock 18C), or compact SMGs with [[handgun]]-like ergonomics (e.g. Micro Uzi).
