What role does the grenadier play in an Infantry Squad?

The grenadier is primarily responsible for providing indirect fire support within an Infantry Squad. This role is crucial because the grenadier utilizes grenade launchers to engage targets at a distance, especially those that are difficult to reach with standard infantry weapons. The ability to deliver explosive ordnance over a range helps to suppress enemy positions or destroy specific threats without exposing the squad to direct fire. Indirect fire support from grenade launchers can significantly enhance the squad's capabilities in both offensive and defensive operations, making the grenadier's role critical in achieving fire superiority and mission success.

In contrast, commanding the squad falls under the responsibilities of the squad leader, who oversees tactical maneuvers and decision-making. Maintaining the radio is typically the duty of a designated communication specialist within the squad, ensuring effective communication with higher command. Tactical movements are led by the squad leader or designated team leaders, focusing on the group's overall strategy and execution on the battlefield.
