What roles are included in the Infantry Squad?

The correct choice accurately reflects the organizational structure of an Infantry Squad as outlined in Army Training Publication 3-21.8. An Infantry Squad typically consists of a Squad Leader, who is responsible for leading and managing the squad's actions and training. The squad is divided into two teams, each led by a Team Leader. This structure allows for effective command and control in combat situations.

Additionally, the squad is further equipped with specialized roles, including Grenadiers who provide indirect fire support with grenade launchers and Automatic Riflemen who carry and operate the squad’s automatic weapons, offering suppressive fire capabilities. The combination of these roles creates a balanced team capable of performing various missions effectively, emphasizing firepower, maneuverability, and adaptability in different combat scenarios.

Other options do not align with the expected structure of an Infantry Squad. For example, mentioning roles such as Designated Marksmen or Support Gunners without corresponding to the correct number of personnel to maintain an effective fighting unit deviates from the established organization detailed in ATP 3-21.8. This understanding of roles ensures that the squad is operationally effective and prepared for tactical engagements.
