  Tenant-Unit Commanders
  E-42. Tenant-unit commanders actively participate in base camp defense planning. Tenant units normally
  provide for their own security and contribute personnel to the protection mission. These assigned or attached
  forces fall under the base camp commander’s TACON. This relationship may not necessarily exist at all
  contingency locations. Regardless, tenant-unit commanders should ensure that provided personnel are
  properly equipped and trained. Key tenant-unit concerns include training, rehearsals, coordination, and
  competing requirements between security and operational tasks. Tenant-unit commander responsibilities
  include—
  * Participating in the preparation and execution of base camp defense plans.
  * Providing for unit internal security.
  * Conducting individual and unit training to ensure readiness for assigned defense tasks.
  * Providing an appropriate share of facilities, equipment, and personnel for the BDOC.
  * Advising the base camp commander on operational concerns specific to their units.
  * Sustaining and administering unit forces.
  * Providing unit requirements for common-user communications systems to the base camp
  commander’s communications element.
  Protection Working Group
  E-43. A working group approach should be used to develop the base defense plan and protection measures
  and to manage protection operations. To interact efficiently, team members should understand the concepts,
  roles, and capabilities of other members. A working-group approach facilitates protection plan development,
  intelligence sharing, and coordination between tenant units.
  BASE CAMP THREATS
  E-44. In most cases, base camps are located where the risk of Level III threats have been eliminated or
  effectively mitigated by the designated AO commander. During large-scale combat operations, base camps
  often become focal points for bypassed or reconsolidated Level III threats. The support area commander must
  be prepared to conduct defensive and offensive tasks by deploying the TCF to repel a Level III attack when
  the threat assessment indicates the possibility of a Level III threat in the support area, regardless of whether
  the element of decisive action/simultaneous activities is currently dominant. Preparations may involve
  significant increases in area denial measures; offensive actions; hardening, dispersal, and other protection
  measures; and immediate reaction to hostile actions.
  E-45. On initial occupation of the base camp site, friendly forces take offensive actions to identify levels of
  enemy presence and eliminate enemy threats in the immediate area, if required. Once the area is cleared and
  the necessary elements of the base camp defense have been established, the base camp commander continues
  managing area security tasks to provide an early warning and to mitigate the risks of threat elements operating
  within the base camp AO. The base camp commander and staff identify gaps in security and requirements
  for additional support or assets. The base camp commander, supported by the staff, coordinates with the AO
  commander to fill identified capability gaps.
  E-46. Base camps are purposely designed and constructed to be resistant to enemy attack and to recover
  quickly so that they can continue to operate. The ability to quickly recover from an enemy attack is enhanced
  through detailed planning and rehearsals of procedures. Base camps must be prepared to defend in any
  direction through flexible base camp defense plans that include the use of dedicated initial-response forces
  positioned to respond to the widest possible range of contingencies.
