  expeditious and effective C2 headquarters for the C2 of EAB engineer structure task-organized across the
  division.
  Supporting collective tasks of an AO include terrain management, information collection, movement
  control, area security in support or consolidation areas, base security and defense, area damage control, and
  stability. The MEB is a brigade headquarters capable of providing C2 of a joint security area for a JFLCC. It
  conducts support area and maneuver support activities for corps and divisions. The MEB is specifically
  designed as an AO controlling brigade to enable BCTs to focus primarily on combat operations. The MEBs
  are only in the Reserve Component. If MEB capabilities are required to deploy early in mission cycles,
  engineer brigades are capable of fulfilling the MEB mission with augmentation of a support control team,
  communications teams, and intelligence analysts. However, taking on a multifunctional role will risk the
  functional brigade’s capability and capacity to C2 functional engineer missions. Figure 6-2 depicts a way to
  task organize for C2 over mobility corridors. See ATP 3-90.4 for a full discussion of planning considerations
  for mobility corridors.
