FM 3-90, ARMY FIELD MANUAL: TACTICS (04 JUL 2001)
FM 3-90, ARMY FIELD MANUAL: TACTICS (04 JUL 2001)., FM 3-90 introduces the basic concepts and control measures associated with the art of tactics. It cannot be read in isolation. To understand FM 3-90, the reader
must understand the operational art, principles of war, and links between the
operational and tactical levels of war described in FM 3-0, Operations. He should
understand how the activities described in FM 3-07, Stability Operations and
Support Operations, carry over and affect offensive and defensive operations and
vice versa. He should understand the operations (plan, prepare, execute, and
assess) process described in FM 6-0, Command and Control, and how that
process relates to the military decision making process and troop-leading
procedures described in FM 5-0, Army Planning and Orders Production. FM 3-90
also refers to joint publications (JPs). Reviewing referenced JPs will also aid in
understanding FM 3-90.
FM 3-90 focuses on the tactics used to employ available means to win in combat.
Those tactics require judgment in application. The ability to seize and secure
terrain, with its populations and productive capacity, distinguishes land forces
conducting decisive offensive and defensive operations. FM 3-90 provides a com-
mon discussion of how commanders from the battalion task force level through
the corps echelon conduct tactical offensive and defensive operations and their
supporting tactical enabling operations. It is not prescriptive, but authoritative.
Tactical fundamentals do not change with the fielding of each new piece of
equipment. However, the integration of new equipment and organizations
usually requires changes in related techniques and procedures. FM 3-90 provides
guidance in the form of combat-tested concepts and ideas modified to exploit
emerging Army and joint capabilities.
