The primary mission of the Infantry platoon and squad is to close with the enemy by means of fire and maneuver to destroy, capture, or repel an assault by fire, close combat, and counterattack.
In order to succeed, Infantry platoons and squads are aggressive, physically fit, disciplined, and well-trained. The inherent strategic mobility of Infantry units dictates a need to be prepared for rapid deployment in response to situations in different operational environments.
This chapter provides a brief discussion of operational environment and an operational overview of unified land operations, and the law of land warfare. It focuses on the role and organization, as well as the duties and responsibilities within the Infantry platoon and squad.
