It provides the reconnaissance platoon's leaders with tactics, techniques, and procedures to exploit its reconnaissance and security capabilities, to reduce its vulnerabilities, and to enable its parent battalion to obtain the information necessary to win on the battlefield. This manual also provides guidance for employing the reconnaissance platoon or infantry platoons that conduct reconnaissance and security operations. The estimate of the situation determines how to apply the doctrine in this manual.
