What are the two primary types of infantry squads in ATP 3-21.8?

The two primary types of infantry squads as outlined in ATP 3-21.8 are the Rifle Squad and the Weapons Squad. The Rifle Squad is the basic building block of the infantry battalion and is designed to engage in close combat and maneuvering operations. It typically consists of several riflemen equipped with individual and crew-served weapons, along with a team leader, to facilitate small unit tactics effectively.

On the other hand, the Weapons Squad is organized to provide additional fire support to the Rifle Squad. This squad includes weapons like machine guns, mortars, and other heavy firepower to enhance the infantry unit's capability in engaging the enemy from a distance and suppressing fire, allowing for maneuverability and tactical advantage on the battlefield.

This distinction between the two squads emphasizes the combined arms approach within infantry operations, where each squad type has a specialized role that complements the other's capabilities during various combat scenarios. Understanding the structure and function of these squads is crucial for mission planning and execution in infantry tactics.
