  campaign plans that address potential threats that put one or more national interests at risk in ways that
  warrant military operations. Contingency plans anticipate the possibility that campaign activities during
  competition could fail to prevent aggression, a need to respond to instability in a key state or region, or
  response to natural disasters. (See JP 5-0 for more information on contingency planning.)
  4-68. The theater army commander and staff assist

  plans, including developing subordinate plans for of a general defense plan to ensure focused
  Army forces as required. Theater army planners preparation for conflict, particularly with regard to
  routinely review and update contingency plans to actions friendly forces take when conflict is

  time-phased force and deployment data (TPFDD).
  This relationship is covered in detail under force
  tailoring in paragraph 4-71. Army corps and divisions that are regionally aligned to a specific combatant
  command may develop subordinate plans as directed. Army corps and divisions train for and rehearse these
  plans in Joint Chiefs of Staff-directed exercises, Army Mission Command Training Program exercises, and
  other training events. (See ADP 5-0 for doctrine on Army planning.)
  4-69. Theater army and select subordinate organizations prepare for operations that could occur in the rear
  areas identified during OPLAN development. Planning and preparing for rear area operations facilitates
  consolidation of gains during armed conflict. Where possible, the theater army should involve the rear area
  command posts of regionally aligned corps and divisions in the development and refinement of plans dealing
  with rear areas likely to be part of those units’ AOs. Regionally aligned units that primarily operate in the
  rear area must be included in planning and exercises whenever possible.
  4-70. Army formations coordinate, rehearse, and support host-nation execution of stability and security
  missions. These efforts help minimize the diversion of combat power from other priorities. Civil affairs units
  have expertise for analyzing potential civil networks to execute these missions. They identify potential civil
  networks through civil preparation of the environment and the civil network development and engagement
  process. Civil preparation of the environment is the continuous development of civil knowledge within an
  area of operations to help commanders identify capabilities within civil society that can be integrated with
  operations for stability and security activities (FM 3-57). This minimizes the requirement for Army forces in
  the rear area and facilitates the maintenance or restoration of host-nation governance and legitimacy.
  Force Tailoring
  4-71. Force tailoring is the process of determining the right mix of forces and the sequence of their
  deployment in support of a joint force commander (ADP 3-0). It involves selecting the right force structure
  for a joint operation from available units within a combatant command and from the Army force pool.
  Commanders then sequence forces into an AO as part of force projection. JFCs request and receive forces
  for each campaign phase, adjusting the quantity of Service component forces to match the effort required.
  TPFDD documents contain both force composition and force flow requirements, and they are the primary
  method by which JFCs tailor their inbound forces. Theater armies tailor forces to meet land force
  requirements as determined by JFCs, and they recommend a deployment sequence to meet those
  requirements. Force tailoring is continuous. (See JP 3-35 for more information on force tailoring and TPFDD
  development.)
  THEATER ARMY ASSIGNED FORCES
  4-72. Each theater army has assigned or allocated theater-level forces that provide additional support across
  the CCDR’s AOR and help the theater army achieve its objectives. Different theaters have different
  subordinate forces with distinct command and support relationships based on theater requirements and force
  availability. The units listed in paragraphs 4-73 through 4-87 are common theater-level formations that
  facilitate operations during competition.
