text: Operations During Competition Below Armed Conflict
  in regions of strategic competition to promote interoperability, build partner conventional warfighting
  capacity, and set conditions for contingency operations. (See ATP 3-96.1 for additional details on the SFAB.)
  CORPS ROLES DURING COMPETITION
  4-90. When a corps is present in a CCDR’s AOR, it provides the C2 linkage between subordinate tactical
  echelons and theater strategic echelons. For example, V Corps oversees theater-assigned units such as the 2nd
  Cavalry Regiment, 12th Combat Aviation Brigade, and the 41st Field Artillery Brigade, and it oversees the
  employment of the MDTF assigned to U.S. European Command. During competition, it is also normal for
  the corps to have an expeditionary sustainment command, operational fires command, expeditionary military
  intelligence brigade, and a medical brigade in general support.
  4-91. During exercises to prepare for large-scale combat operations, the corps fills one of three roles. The
  corps can be designated as tactical land headquarters employing multiple divisions. It may also assume the
  role of a joint task force headquarters or land component command headquarters during a contingency
  operation or training event, after it undergoes the necessary training and joint augmentation. When the corps
  is the land component command headquarters, it also serves as the ARFOR. (See FM 3-94 and ATP 3-92 for
  more information on the corps.)
  DIVISION ROLES DURING COMPETITION
  4-92. Divisions are often the primary interface with various unified action partners during competition. When
  regionally aligned, a division with a tailored package of subordinate brigades and other enablers—both
  Regular Army and Reserve Component—is allocated to a CCDR to help execute the CCP. Examples of
  additional enablers include maneuver enhancement brigades and civil affairs, military intelligence, military
  police, CBRN, psychological operations, explosive ordnance disposal, and engineer units.
  4-93. A regionally aligned division normally works with multinational partners to conduct security
  cooperation over extended periods. By establishing habitual relationships, divisions help assure allies, build
  trust with partner nations, and build interoperability with them and other unified action partners. Divisions
  help partners build shared situational understanding and partner capacity. They also deter conflict through
  the conduct of various activities such as exercises, training, equipping, education, conferences, and military
  staff talks. Division support to security cooperation helps shape regional stability by—
  (cid:122) Building defense relationships that promote U.S. security interests.
  (cid:122) Developing friendly military capabilities for self-defense and multinational operations.
  (cid:122) Providing the division and other U.S. forces with peacetime and contingency access to host nations
  to prevent and deter conflict.
  (cid:122) Improving readiness to incorporate allied or partner formations.
  4-94. Division headquarters provide direct C2 of the brigades tasked to conduct specific operations
  supporting security cooperation and interoperability development with partners. They provide training
  resources and oversight to brigades at home station. Division headquarters are responsible for leader
  development down to the battalion level. They continuously improve the readiness of Army forces over
  which they have influence, protecting their time and ensuring that demanding, realistic training is the first
  priority.
  4-95. Division headquarters provide subject matter expertise to assist brigades as they prepare for missions
  or capstone training exercises, to include awareness of NATO or American, British, Canadian, Australian,
  and New Zealand (known as ABCANZ) interoperability standards when forces from those nations are
  involved. Low density military occupation specialties or specialized units may benefit from the division
  consolidation of training events. Divisions have subject matter experts in low density specialties who
  develop, implement, execute, and evaluate training programs across several echelons. (See FM 3-94 and
  ATP 3-91 for a further discussion of division roles and responsibilities.)
  BRIGADE COMBAT TEAMS DURING COMPETITION
  4-96. BCTs provide CCDRs with a combined-arms, close combat force that can operate as part of a division
  or a joint task force. During competition, they focus on perfecting tactical tasks in preparation to execute
