What type of weapon is the M4 classified as?

The M4 is classified as a rifle, which is a type of firearm designed for accurate shooting at long ranges. Specifically, the M4 is a lightweight, air-cooled, gas-operated, magazine-fed carbine that is often used by military personnel due to its versatility and effective range. It is designed to fire a high-velocity cartridge, providing enhanced accuracy and terminal performance compared to other weapon types. The rifle classification encompasses firearms that have rifled barrels, allowing for improved projectile stability and accuracy over distances. Other options such as pistol, shotgun, and submachine gun each represent different characteristics and uses for weapons that do not align with the M4's design or intended functionality.
