FAQ
Frequently Asked Questions
An assault rifle (e.g., M16, AK-47) fires an intermediate-power rifle cartridge and is often select-fire. A submachine gun fires lower-power pistol cartridges, making it smaller, lighter, and with less range.
Not exactly. A machine pistol is essentially a fully automatic pistol, often designed to be fired one-handed. A submachine gun is larger, often has a shoulder stock, and is designed for two-handed, controlled automatic fire. The terms are sometimes used interchangeably for compact SMGs.
The prefix 'sub-' means 'below' or 'less than.' It indicates the weapon is smaller, lighter, and fires less powerful ammunition than a full-sized, crew-served or belt-fed machine gun.
Their use has declined in frontline infantry roles, largely replaced by compact assault rifles. However, they are still used by special forces, law enforcement, and vehicle crews where a compact, high-rate-of-fire weapon is advantageous.
