  1-53. Site exploitation supports the locate task. Systematic examination of the last known location of an
  isolated person or group offers the opportunity to gather information and material that may lead to finding
  those isolated or determining what happened to them. Isolated persons leave visible and invisible evidence
  of their presence. They abandon equipment, scratch names and dates, write notes, or leave fingerprints,
  hair, or body fluids. These clues can lead to forensic analysis and identification. Interviewing persons with
  knowledge of the event or area, including members of the local population, contributes to information
  collection. Site exploitation not only provides a recovery force with tactical information to assist an
  ongoing recovery mission, but it may also lead to the discovery of information with operational or strategic
  value. ATTP 3-90.15 describes a systematic and comprehensive approach to obtain information of value.
  1-54. Enemies know Army forces will attempt to recover isolated persons. Therefore, Army forces
  consider whether an enemy is luring friendly forces into an ambush based on its knowledge of the isolating
  event. ISG must contain near and far recognition signals and means to determine if the communication
  from isolated persons is genuine and the location accurate. Authentication is not just a single action.
  Recovery forces authenticate isolated persons and verify location as many times as necessary. Effective
  operations require authenticating the report and determining the precise location of isolated persons. Once
  the locate task is completed, forces determine how to support isolated persons.
  Support
  1-55. The support task involves providing aid to the isolated person and to the isolated person’s family as
  determined by operational objectives. The command provides all support necessary to enable isolated
  persons to survive until recovered. Commanders ensure the forces selected to support isolated persons
  know the objectives and can achieve them. Decision makers must properly assess and mitigate risks to
  complete the support task successfully.
  1-56. Support for isolated persons often requires physical security to keep an enemy force from finding and
  capturing them. This support can be fire support or diversionary attacks against an enemy to divert its
  attention from isolated individuals or groups. Support items may include food, shelter, clothing,
  communications equipment, locator beacons and other position-locating equipment, medical supplies,
  protective equipment, weapons, ammunitions, and maps. Units can air drop these items to the isolated
  person.
  1-57. If able, isolated persons inform the supporting force of their needs. While providing support, the
  recovery force obtains information from isolated persons and combines it with available intelligence to
  determine appropriate recovery actions. The recovery force adds appropriate information to the report of
  isolation. Information requirements during this exchange include—
  * An understanding of the ISG.
  * Physical condition (wounded, sick, tired, exhausted, or unable to move).
  * State of morale.
  * Presence of the enemy.
  * Equipment and supply status.
  * Distance to closest friendly unit.
  * Cause of the isolation.
  * Ability to self-recover.
  * Ability to escape and evade.
  * Recognition of the individual’s own situation.
  * Capability to signal or otherwise communicate with friendly and recovery forces.
  * Availability of terrain suitable for access to the location by air, ground, or waterway.
  1-58. The support task extends to the home front. The Army provides casualty assistance after the
  member’s status is determined. Army senior commanders make a decision on the timing of notification of
  next of kin. Guided by Army notification policy, the owning unit and supporting home station installation
  provide the next of kin with accurate status updates of their family member. Further, they provide the
  spiritual, moral, medical, financial, and administrative support the family needs to endure the crisis. The
  Army does not task family, friends, or private groups to provide support or to act as a substitute for the
