What is the primary 40mm grenade launcher used by Marines for close-in fire support?

Explanation:
The Marines use the M203 under-barrel grenade launcher as the primary 40mm system for close-in fire support because it stays with the rifle, delivering explosive rounds without breaking contact or slowing the shooter. That rifle-integrated design lets a Marine fire 40mm grenades and then immediately продолжить engaging targets with the rifle, which is crucial in short-range firefights. It’s lightweight and simple to operate, with a single-shot action that keeps the weapon maneuverable while still offering a range of rounds (fragmentation, smoke, illumination) for flexible missions. The other options serve different roles: the MK19 is a heavier, crew-served automatic launcher used for sustained area suppression from a distance; the M79 is an older single-shot launcher that is slower to reengage; and the M32 is a multi-shot under-barrel launcher that is not as widely standardized for close-in, rifle-integrated use. Therefore, the M203 best fits the Marines’ need for immediate, maneuverable fire support at close range.
