Small arms are portable, individual or crew-served firearms designed for personal use in military, law enforcement, or civilian applications. They typically include handguns (pistols, revolvers), rifles, carbines, submachine guns, shotguns, and light machine guns.

✅ Key Characteristics of Small Arms:
Man-portable: Can be carried and operated by an individual or a small team.
Caliber: Usually below 20mm (e.g., 5.56mm, 7.62mm, 9mm, .50 caliber).
Uses: Infantry combat, self-defense, law enforcement, and sport shooting.
Small arms are distinct from heavy weapons, which require vehicles, crews, or mounting systems for operation, such as heavy machine guns, mortars, and artillery.
