This manual defines the role, operational requirements, mission tasks, battlefield functions, and command and control relationships of Infantry battalions organic to the Infantry Brigade Combat Team (IBCT). Users of it must understand the elements of doctrinal literature and their relationship to each other. The commonly used terms, tactics, techniques, and procedures are both interrelated and mutually supportive. However, each term has its own usage, level of detail, and place in the hierarchy of doctrinal publications. FMs provide doctrine, tactics, and some techniques, while mission training plans (MTP) provide techniques and procedures. Procedures can also be found in publications such as unit standing operating procedures (SOP) and Soldiers’ manuals as well as others. Tactics, techniques, and procedures, in that order, become more prescriptive and require less judgment as these elements are applied. This manual is provided for use by Infantry battalion commanders and staffs, company commanders, and special platoon leaders.
