  units. Within an assigned AO, the designated support area land owner may keep centralized control of some

  * Locating, isolating, and containing the incident.
  * Isolating danger or hazard areas.
  * Mitigating personnel and material losses.
  * Reestablishing security.
  * Assessing the situation and damage.

  LOCAL SECURITY
  4-75. Local security is low-level security activities conducted near a unit to prevent surprise by the enemy
  (ADP 3-90). Local security provides immediate protection to friendly forces and is typically performed by a
  unit for self-protection, but it may also be provided by another unit when the security requirements are greater
  than the unit security capabilities. Local security may include countermobility and survivability activities.
  Area security activities take advantage of the local security measures performed by all units (regardless of
  their location) in an AO, and all local security activities should be linked to the broader area security activities.
  4-76. Local security includes any local measure taken by units that protect against enemy actions. It involves
  avoiding enemy detection or deceiving the enemy about friendly positions and intentions. Local security
  prevents a unit from being surprised, and it is an important part of maintaining the initiative. The requirement
  for maintaining local security is an inherent part of all operations. Units use active and passive measures to
  provide local security.
  4-77. Active local security measures include but are not limited to―
  * Observation posts.
  * Patrols.
  * Unmanned aerial systems.
