  KEY BASE DEFENSE STRUCTURES
  6-59. The key base defense positions consist primarily of bunkers and towers in the base perimeter area.
  The positioning of bunkers and towers affords maximum observation and mutually supporting fires over
  the area forward of the perimeter to include the perimeter barrier and sensor system. See FM 3-34.300
  for specifics on the construction of defensive positions associated with base defense (Figure 6-8).

  BASE DEFENSE EXERCISES
  6-60. All base defense plans must be rehearsed, and should include the testing of the base defense alarm
  and communication systems. Diverse elements of the defense force must be trained to act in a coordinated
  effort. These exercises familiarize all elements of the defense force and base tenant units with their
  assignments in base defense. Exercises must be conducted frequently under various weather conditions
  during daylight and darkness. Defense exercises include the following:
  • Defense of sectors of responsibility, to include—
  (cid:131) Rehearsing counterattacks.
  (cid:131) Manning defense positions.
  • Employment of the reserve for counterattacking and for reinforcing the defense positions.
  • Coordination of supporting fires and other means of support.
  • Mass casualty exercises.
  • Coordination with other forces assigned to base that may be used in a ground defense role.
  • Command post exercises.
