What roles typically comprise a Fire Team?

The correct answer identifies the fundamental roles that constitute a Fire Team within an Infantry Rifle Platoon. A Fire Team typically consists of a Team Leader, who is responsible for the tactical direction and leadership of the team; a Grenadier, who provides indirect fire support with grenade launching capabilities; a Rifleman, who engages with the enemy using a standard rifle and supports the team in direct fire; and an Automatic Rifleman, who uses a light machine gun to deliver sustained fire and enhance the team's firepower.

These roles are specifically designed for ground combat scenarios where teamwork, fire support, and flexibility are essential. Each member's responsibilities complement each other, allowing the Fire Team to operate efficiently and effectively in various combat situations, whether it be in offense or defense.

The other options listed reflect different roles and organizational structures not associated with a standard Fire Team. While some may have roles relevant to military operations, they do not fit the specific makeup of a Fire Team as described in ATP 3-21.8.
