Theater Army, Corps, and Division Operations (FM 3-94 / FM 3-92 / FM 3-93)

FM 3-94, "Theater Army, Corps, and Division Operations," provides Army doctrine for the theater army, corps, and division. FM 3-94 explains the organization of the theater army, corps, and division headquarters and their respective command posts. It establishes the roles for each headquarters, including their respective contributions to joint operations. It discusses subordinate units and each headquarters' organization of its units, establishment of command and support relationships, and conduct of operations. The unique and crucial role of the Army is to provide landpower to the geographic combatant commanders. Landpower, as ADP 1 notes, is "is the ubiquitous tool of the joint force-often decisive, sometimes indirect, but indispensable." FM 3-94 examines the employment of Army forces within a geographic combatant command. It describes how the Army supports the combatant commander across the range of military operations in that area of responsibility (AOR).
