It discusses the theater army's responsibilities to support the combatant commander's theater campaign plan across the GCC's area of responsibility (AOR), referred to as the theater army's AOR-wide support responsibilities. It also discusses the theater army's role in theater opening, including reception, staging, onward movement, and integration (RSOI) of Army and joint forces provided to the joint force commander (JFC) in joint operations areas (JOA) opened within the AOR, and the theater army's dominant role in sustaining Army and joint forces, as directed, across the AOR.

The Army believes that the U.S. will continue to be engaged in an era of ¿persistent conflict¿ -- a period of protracted confrontation among states, non-state, and individual actors increasingly willing to use violence to achieve their political and ideological ends. This manual is a revolutionary departure from past doctrine. Commanders will employ offensive, defensive, and civil support operations simultaneously as part of an interdependent joint force to seize, retain, and exploit the initiative, accepting prudent risk to create opportunities to achieve decisive results. This ed. will take us into the 21st century urban battlefields among the people without losing our capabilities to dominate the higher conventional end of the spectrum of conflict.

FM 3-94, "Theater Army, Corps, and Division Operations," provides Army doctrine for the theater army, corps, and division.

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).
