The Army provides readily available and trained regionally aligned and globally responsive forces to prevent conflict, shape the security environment, and win wars. Army forces maintain proficiency in the fundamentals of decisive action, and possess capabilities to meet specific geographic combatant command requests. Regionally aligned forces provide combatant commanders with an Army headquarters tailored to missions from tactical level to joint task force capable. (See FM 3-94.) The Infantry battalion of the Infantry brigade combat team shapes the security environment and wins across the range of military operations. ATP 3-21.20 addresses the tactical application of techniques associated with the offense, the defense, and operations focused on stability. ATP 3-21.20 does not discuss defense support of civil authorities.
