  5-18. Commanders do not delay initiating cooperation and coordination in advance of potential isolation
  incidents. This includes the potential isolation of Soldiers or civilians. They anticipate the need and do not
  allow inadequate coordination and training to limit effectiveness of recovery operations. They plan to
  compensate for differences in communications equipment, signals, training, and procedures. Commanders
  consider the makeup of the work force of potential partners.
  ISOLATION RISK IN STABILITY
  5-19. Risks impact personnel recovery operations. The most common type is accidental risk. Since military
  operations are inherently dangerous, the chance of accidents increases. Accidents often cause or contribute
  to isolation. Other types of risk include the presence of a threat from enemy forces, criminal elements, or a
  hostile environment.
  5-20. Stability tasks may not require the same level of protection as major combat operations. A
  commander and staff still conduct risk assessments to determine the probability of an isolation incident
  occurring and its potential impact on mission accomplishment. For instance, figure 5-1 demonstrates how
  the risk of a Soldier becoming isolated may be very low, but its impact on the mission may be high
  (condition A). Conversely, the probability of an isolation incident may be high but the immediate impact on
  an ongoing operation may be low (condition B). With respect to personnel recovery operations, Army
  commanders assess the risk, apply control measures, and supervise the operation.
  Figure 5-1. Risk curve
  5-21. Personnel recovery challenges commanders of stability operations to respond quickly to an isolation
  incident with sufficient forces. In most stability situations, the final assessment of risk is a judgment call by
  the commander. The commander considers not only the severity of the negative outcome but also its
  probability. (See ATP 5-19 for more detailed information on risk management.) Generally, the risk of
  isolation for the friendly force is proportional to the size of that force and the degree and distance of
  separation from other friendly forces, including recovery forces. See figure 5-2 for an illustration of the
  relationship between force size and isolation.
