1-1. Tactics is the employment, ordered arrangement, and directed actions of forces in relation to each other. ADP 3-90 is the primary publication for the offense and defense at the tactical level. It is authoritative and provides guidance in the form of combat-tested concepts and ideas modified to take advantage of Army and joint capabilities. It focuses on the tactics used to employ current capabilities to prevail in combat. Tactics are not prescriptive. Tacticians use creativity to develop solutions for which enemy forces are neither prepared nor able to cope.
