What is the primary function of the M203?

The M203 is primarily designed as a support weapon, allowing infantry units to engage targets at a greater distance than standard rifles. It serves to enhance the firepower of a squad without increasing the number of personnel or weapons needed. By functioning as an under-barrel grenade launcher, the M203 can deliver explosive rounds that are effective for suppressing enemy positions, creating diversions, and providing indirect fire support. The ability to launch grenades from the rifle's platform means that troops can maintain standard combat stances while gaining the advantage of versatile fire capabilities. This role is crucial in supporting the overall combat operations of ground forces, making it an essential tool for providing tactical advantage in various scenarios.
