  Main Body
  6-137. The bulk of the BCT’s combat power is in the main body. The main body follows the advance guard
  and keeps enough distance between itself and the advance guard to maintain flexibility. The movement
  formations and movement techniques maneuver battalions/squadrons and subordinate companies/troops (see
  figure 6-16) use when part of the main body are always METT-TC dependent, keeping in mind the elements
  of the main body must be responsive to the actions of the advance guard. The BCT commander may designate
  a portion of the main body as the reserve.
