  * The defending force may not gain a timely, accurate picture of the attacking enemy force’s
  locations and dispositions required by the striking force to execute the main effort.
  * The decentralized operations required in a mobile defense may increase potential for friendly fire
  incidents.
  Command and control systems improve the ability of the friendly force to gain and maintain a COP, which
  reduces the risk associated with this type of defense. Figure 10-1 depicts a mobile defense.

  10-5. Just as in an area defense, commanders of a mobile defense consider how their operations impact the
  civilian population within the assigned area. The impact of the population is of more concern during a mobile
  defense than it is during an area defense because the scope of maneuver and tempo of operations is much
  larger. Civilian attempts to avoid advancing enemy formations and locations where combat occurs will
  impede the ground maneuver of defending units unless commanders account for their presence and provide
  alternative routes for dislocated civilians. Units communicate these routes to the civilian population using
  various means to ensure they receive the information. Ideally, local nation civilian or military organizations
  provide civilian traffic regulations and immediate essential services along those civilian evacuation routes
  (along with the other five primary stability tasks). However, if the local nation cannot perform these tasks,
  the defending unit will have to perform them. Screening of civilians by units is necessary in this case to
  preclude enemy agents from using these routes to infiltrate friendly defensive positions. At all times,
  commanders must meet legal obligations to local civilian populations.
  ORGANIZATION OF FORCES FOR A MOBILE DEFENSE
  10-6. Units organize the main body into two principal groups: the fixing force and the striking force. In a
  mobile defense, reconnaissance and security, reserve, and sustaining forces accomplish the same tasks as in
  an area defense. Units adjust their task organization before committing subordinate units to combat. Figure
  10-2 illustrates the organization of forces for a mobile defense.
