text: Support Area Responsibilities
  Critical Asset Security
  4-48. Critical asset security is the protection and security of personnel and physical assets or information
  that is analyzed and deemed essential to the operation and success of the mission and to resources required
  for protection (ADP 3-37). Critical assets can be people, property, equipment, activities, operations,
  information, facilities, or materials. For example, important communications facilities and utilities, analyzed
  through criticality assessments, provide information to prioritize resources while reducing the potential
  application of resources on lower-priority assets. Stationary weapons systems might be identified as critical
  to the execution of military operations and, therefore, receive additional protection. The lack of a replacement
  may cause a critical asset to become a top priority for protection.
  4-49. The MEB staff must use criticality, threat vulnerability, and threat probability to prioritize identified
  critical assets. Once the staff determines which assets are critical for mission success, it recommends
  protection priorities and establishes a protection prioritization list for the support area (see annex A). The
  protection prioritization list helps the MEB commander identify or assess assets that require protection
  prioritization within the support area. Not all assets listed on the protection prioritization list receive
  continuous protection. Some critical assets only receive protection assets based on available resources. It is
  the responsibility of the MEB staff to provide the assessment and recommended prioritization list to the
  commander for approval. The corps and division information operations elements are responsible for
  integrating and synchronizing information-related capabilities that support and complement critical asset
  protection against bypassed regular forces, irregular forces, and hybrid threats in the support area. The
  electronic warfare operations is responsible for synchronizing electronic attack against Level II and Level III
  threats. Coordination between the information operations/operations security (OPSEC) officers and the signal
  officer emphasizes electromagnetic signature masking through terrain and directional antenna usage. The
  protection prioritization list is continuously assessed and revised throughout each phase, transition, or major
  activity of an operation. See ADP 3-37 for additional information on critical assets and the protection
  prioritization list.
  Node Protection
  4-50. Command posts and operations centers are often protected through area security techniques that
  involve the employment of protection and security assets in a layered, integrated, and redundant manner.
  This can often keep hostile threats at a distance by maximizing the standoff distance from explosive effects,
  while keeping the protected asset outside the range of enemy or adversary direct-fire weapons and
  observation. CBRN sensors may be emplaced around critical nodes to provide early warning to friendly
  forces of incoming enemy CBRN strikes, particularly at static sustainment areas and command and control
  nodes.
  High-Risk Personnel Security
  4-51. High-risk personnel are personnel who, by their grade, assignment, symbolic value, or relative
  isolation, are likely to be attractive or accessible terrorist targets (JP 3-26). When units identify a significant
  risk based on a verified threat from an intelligence source to selected personnel, the local commander has the
  ability to organize security details from internal resources. Special precautions are taken to ensure the safety
  and security of these individuals and their family members. Commanders must ensure that any security details
  are properly trained and equipped and may request additional protective detail support if needed. See
  ATP 3-39.35 and DODI O-2000.22.
  Movement Corridor
  4-52. A movement corridor is a designated area established to protect and enable ground movement along a
  route (ADP 3-37). Units establish a movement corridor to set the conditions to protect and enable movement
  of traffic along a designated surface route. Units conduct synchronized operations within the movement
  corridor, such as reconnaissance, security, mobility, and information collection for forces that require
  additional command and control, protection, and support to enable their movement. See ADP 3-37 for
  additional information on the establishment of a movement corridor.
