text: Base Camp and Base Cluster Security and Defense
  within the protection warfighting function in ADP 3-37 and the associated defensive tasks detailed in
  FM 3-90-1, including—
  * Comprehensive. Base camp and base cluster protection is an all-inclusive utilization of
  complementary and reinforcing protection tasks and systems available to base camp commanders
  to preserve the force.
  * Integrated. Base camp and base cluster protection is integrated with other activities, systems,
  efforts, and capabilities associated with base camp missions to provide strength and structure to
  the overall effort. Integration must occur vertically and horizontally throughout the process.
  * Layered. Base camp and base cluster protection capabilities are arranged using a layered approach
  to provide strength and depth. Layering reduces the destructive effect of a threat or hazard.
  * Redundant. Base camp and base cluster protection efforts are often redundant anywhere that a
  vulnerability or point of failure is identified. Redundancy ensures that specific activities, systems,
  efforts, and capabilities that are critical for the success of overall base camp protection have a
  secondary or auxiliary effort of equal or greater quality.
  * Enduring. Ongoing base camp and base cluster protection activities maintain the objectives of
  preserving combat power, populations, partners, essential equipment, resources, and critical
  infrastructure throughout the base camp life cycle.

  E-22. Base camp and base cluster security and defense capabilities are employed using a layered approach
  to provide strength and depth. Layering reduces the destructive effect from any single attack or hazard
  through the dissipation of energy or the defeat of the attacking force. A layered defense slows threat attacks
  and provides time for friendly defensive forces to assess, decide, and respond. Obstacles, such as barbed wire
  fences, jersey barriers, T-walls, berms and ditches, bastion barriers, networked munitions, and direct-fire
  positions and elements are deployed in depth, in a concentric fashion, to provide maximum protection.
