  command post for oversight, coordination, and synchronization of administrative and logistics support for
  assigned, attached, or OPCON units of the tactical command post.
  MAIN COMMAND POST
  4-26. The main command post is deployable and is the corps primary command post. The main command
  post controls current operations, performs detailed analysis, and plans future operations. The functions
  performed in the main command post enable the success of subordinate units in the close area. The main
  command post directs tasks that occur in the close, deep, and support areas. It must plan and synchronize the
  employment of capabilities across all warfighting functions. Commanders can employ the main command
  post to—
  * Control every aspect of the overall mission.
  * Plan operations, including branches and sequels.
  * Integrate intelligence into current operations and plans.
  * Synchronize the targeting process, including target development to joint standards.
  * Plan and synchronize sustaining operations.
  * Assess the overall progress of operations.
  * Receive reports for subordinate units and prepare reports required by higher echelon headquarters.
  4-27. The main command post includes the command group and most of the coordinating, special, and
  personal staffs. It is staffed to organize into five functionally focused cells (including intelligence, movement
  and maneuver, fires, protection, and sustainment) with broad responsibilities for coordinating these
  warfighting functions across the corps. The movement and maneuver cell, augmented by subject matter
  experts from across the staff, organizes into the three integrating cells: the current operations integration cell,
  future operations cell, and plans cell. The movement and maneuver cell also includes several specialized
  elements, including the airspace element. It also receives USAF elements structured to support the
  headquarters’ assigned role. As a tactical headquarters, the corps receives a corps tactical air control party.
  As a joint force land component command in limited contingency operations, it receives a joint air component
  coordination element. Because there is no command and control functional cell, staff elements responsible
  for command and control tasks either receive direction and priorities from the chief of staff or work in an
  integrating cell. Liaison elements from higher echelon, adjacent, and subordinate units locate at the main
  command post. If provided, the special operations forces coordinating element also locates here.
  4-28. The main command post is significantly larger than the other command posts, and it is less mobile.
  Although it does have some limited mobility, it requires additional support from a truck company for full
  mobility. The main command post is capable of 24-hour operations indefinitely, and it needs to only pause
  operations to displace. The main command post is the only command post that can perform all of the functions
  of the headquarters without the other command posts functioning. Threat forces can find the main command
  post more easily than the other command posts due to its size and electronic signature. Commanders and
  staffs plan for placement of the main command post to mitigate vulnerability to threat targeting capabilities.
  TACTICAL COMMAND POST
  4-29. The primary role of the tactical command post is as the alternate command post of the corps. It provides
  a place from which the commander can exercise command and control while the main command post deploys
  or displaces. In a high-threat situation, the tactical command post may offset from the main command post
  to provide redundancy in the event of an attack on the main command post. Commanders can also employ it
  as—
  * A task force headquarters.
  * The controlling command post for a specific task within a larger operation such as a gap crossing,
  a passage of lines, a relief in place, or an air assault operation.
  * The controlling headquarters for the decisive operation or a specific shaping operation.
  * A forward-positioned headquarters during deployment.
  * The controlling headquarters for a JSA.
