Which type of weapon is the M203 considered to be?

The M203 is considered a grenade launcher, which is a weapon designed specifically to launch grenades at targets from a platform, typically mounted to a rifle. It allows for the delivery of explosive projectiles at a distance, enhancing the firepower of infantry units. The design of the M203 permits it to be attached to various rifles, most commonly the M16 or M4 series, providing versatility on the battlefield.

This functionality distinguishes it from other types of weapons. Unlike rifles, which fire bullets, or pistols, which are shorter-barreled firearms intended for close-range engagements, the M203's primary role is to project grenades, making it crucial for indirect fire support. Additionally, it is not classified as a rocket launcher, which is a different category of weapon that typically utilizes self-propelled munitions. Thus, identifying the M203 as a grenade launcher accurately reflects its capabilities and intended use in military operations.
