  * The establishment of specific levels of alert within the unit. The commander adjusts those levels
  based on the factors of METT-TC.
  * The establishment of stand-to times. The unit standard operating procedure details the unit
  activities during the conduct of stand-to.
  4-78. Passive local security measures include but are not limited to―
  * Camouflage and concealment.
  * Movement control.
  * Noise and light discipline.
  * Proper communications procedures.
  * The employment of available ground sensors.
  * The use of night vision devices and daylight sights to maintain surveillance over the area
  immediately around the unit.
  * The incorporation of emission control to prevent the enemy from detecting, identifying, and
  locating friendly forces.
  TACTICAL COMBAT FORCE
  4-79. A tactical combat force is a rapidly deployable, air-ground mobile combat unit, with appropriate
  combat support and combat service support assets assigned to and capable of defeating Level III threats
  including combined arms (JP 3-10). The TCF is task-organized to the MEB commander when it is required
  to defeat Level III threats throughout the support area. An infantry battalion, Stryker battalion, or a combined
  arms battalion can be assigned as the TCF for the support area commander’s AO. The TCF size, composition,
  and response time is based on mission requirements.
  PERSONNEL RECOVERY
  4-80. Army personnel recovery refers to the military efforts taken to prepare for and execute the recovery
  and reintegration of isolated personnel (FM 3-50). Personnel recovery is the overarching term for operations
  that focus on recovering isolated personnel before captivity. Isolation refers to a tactical situation that requires
  isolated personnel to evade or operate in captivity as an extension of the battlefield. Every unit must have
  procedures in place to recover personnel.
  4-81. Commanders must integrate personnel recovery throughout operations. This requires an understanding
  of the complex, dynamic relationships between friendly forces, the enemy, and the operational environment.
  This understanding helps commanders visualize and describe their intent for personnel recovery and assists
  them in developing focused isolated Soldier guidance. Personnel recovery guidance is contained in various
  parts of the order, including the base order, appropriate annexes, appendixes, tabs, and exhibits. For additional
  information on personnel recovery, see FM 3-50.
  AIRSPACE MANAGEMENT
  4-82. The MEB is staffed with an air defense airspace management cell that is responsible for planning,
  coordinating, integrating, and controlling air defense and airspace management to integrate brigade airspace,
  including AMD. The MEB staff coordinates with the division joint air ground integration center as required
  to deconflict and integrate the airspace within the support area. See FM 3-52 and JP 3-52.
  Note. The air defense airspace management cell capabilities resident in a MEB does not have the
  full brigade aviation element or United States Air Force Tactical Air Control Party found in
  maneuver brigades.
