Leading, Planning & Conducting Tactical Operations This is the second revised edition of The Small Unit Tactics SMARTbook (SUTS2), featuring the full scope of new material and Doctrine 2015 updates to include ADP/ADRP 3-90 Offense and Defense, ADP/ADRP 5-0 The Operations Process, ADP/ADRP 6-0 Mission Command and more than 20 additional references. Chapters and topics include tactical mission fundamentals, the offense, the defense, stability and counterinsurgency operations, tactical enabling tasks (security, reconnaissance, relief in place, passage of lines, encirclement, and troop movement), special purpose attacks (ambush and raid), urban and regional environments (urban, fortified areas, desert, cold region, mountain, and jungle operations), patrols and patrolling. This second printing of SUTS2 features updated "lay-flat" binding with spine in place of the original plastic-comb binding. Tactics is the employment and ordered arrangement of forces in relation to each other. Through tactics, commanders use combat power to accomplish missions. The tactical-level commander uses combat power in battles, engagements, and small-unit actions. Establishing a common frame of reference, doctrine provides a menu of practical options based on experience. It provides an authoritative guide for leaders and Soldiers but requires original applications that adapt it to circumstances. The Small Unit Tactics SMARTbook translates and bridges operational-level doctrine into tactical application -- in the form of tactics, techniques and procedures -- and provides the "how to" at the small-unit level, providing a ready reference at the battalion, company, platoon, squad and fire team level.
