  PROTECTION
  8-175. BCT activities associated with executing security operations (see FM 3-90-2), physical security (see
  ATP3-39.32), antiterrorism (see ATP 3-37.2), and operations security (see FM 3-13) tasks enhance the
  security of the command within an areaof operations. In large part, the measures within these four tasks are
  the same or complementary. Stability-focused operations closely resemble BCT activities for these tasks
  during the conduct of offensive- and defensive-focused operations though the BCT generally works closer
  with civilian inhabitants. (See ATP 3-91 for additional information.)
  Establish and Maintain Security
  8-176. The BCT conducts security operations to ensure freedom of movement and action and to deny the
  enemy the ability to disrupt operations. Commanders combine offensive, defensive, and stability operations
  tasks, and information collection means to protect friendly forces, populations, infrastructure, and activities
  critical to mission accomplishment. The BCT integrates with partner military, law enforcement, and civil
  capabilities to establish and maintain security. The ability to establish control is critical to consolidating gains
  in the wake of successful military operations.
  8-177. Security operations prevent surprise, reduce uncertainty, and provide early warning of enemy
  operations. Warning of enemy operations provides forces with time and maneuver space with which to react
  and develop the situation. Security operations prevent enemies from discovering the friendly plan and protect
  the force from unforeseen enemy actions. Security elements focus on preventing the enemy from gathering
  EEFI. Security is a dynamic effort that anticipates and thwarts enemy collection efforts. When successful,
  security operations allow the BCT to maintain the initiative within the stability environment.
  8-178. Protection is a continuous activity; it integrates all protection capabilities to safeguard bases, secure
  routes, and protect forces. Effective physical security and antiterrorism measures, like any stability measure,
  overlap and are employ in-depth. For example, planners determine how military police support enhances unit
  physical security and antiterrorism capabilities by performing area security operations inside and outside an
  echelon support area or consolidation area. Military police also conduct response force operations to defeat
  LevelII threats against bases or critical assets and delay Level III threats in an echelon support area until a
  tactical combat force can respond. (See ATP 3-39.11 for information on military police special reaction
  teams.)
  8-179. The BCT commander pays attention to physical security and antiterrorism operations throughout the
  stability environment. This is especially true when subordinate units conduct noncontiguous operations, as
  the success of the BCT mission may depend on protecting support areas from enemy attacks. The
  commanders must address the early detection and immediate destruction of enemy forces attempting to attack
  support or consolidation areas. Enemy attacks against sustainment and other facilities can range in size from
  individual saboteurs to enemy airborne or air assault insertions targeted against key military and civilian
  facilities and capabilities. These enemy activities, especially at smaller unit levels, may even precede the
  onset of large-scale combat and be almost indistinguishable from terrorist acts. The BCT implements
  operations security and other information protection measures to deny the enemy force information about
  friendly dispositions.
  Note. Within the stability environment, deploying battalions and higher echelons should have a
  trained Level II antiterrorism officer assigned. An assigned antiterrorism officer works to ensure
  that security considerations are integrated in base designs and unit operations. These individuals
  guide their units in conducting threat assessment, criticality assessments, and vulnerability
  analysis to determine each unit’s vulnerability to terrorism. (See ATP 3-91 and ATP3-37.2 for
  additional information.)
