Within a squad, who is designated to carry the M203 Grenade launcher?

The designation of the individual who carries the M203 Grenade Launcher within a squad is the Grenadier. This role is specifically focused on utilizing the M203, which is an attachment that allows for the launching of 40 mm grenades. The grenadier is trained to understand the capabilities of the launcher, the types of grenades available, and the appropriate tactical situations for its use.

In a combat scenario, the grenadier plays a crucial role in providing indirect fire support, allowing for increased firepower beyond what standard rifles can deliver. The grenadier's ability to launch grenades can effectively engage enemy personnel and soften up enemy positions, making them an essential part of the squad's overall firepower and tactical strategy.

The other roles within the squad, while important, do not specifically carry the M203. The rifleman is typically responsible for carrying a standard-issue rifle, the automatic rifleman focuses on providing sustained fire with a light machine gun, and the corpsman is primarily tasked with medical support and does not carry weapons as part of their standard duties. This distinction highlights the unique responsibilities of each squad member, particularly that of the grenadier in relation to the M203.
