  potential sources of information. Local national and third-country national
  employees can be a prolific source of information about local attitudes and
  events, particularly in a restrictive environment where US contact with the
  local population is curtailed. Their information can also be significant in a
  force protection role. The HUMINT collector must register these individuals
  with the J/G2X. While the HUMINT collector is assessing the local national
  employee as an intelligence source, CI agents are assessing the same source
  pool as potential security risks.
  5-19. Coordination between HUMINT collectors and CI elements is essential
  for deconfliction and to avoid duplication of effort. If the HUMINT collector
  identifies an employee that may be of CI interest, he should immediately
  notify the appropriate CI unit.
  Displaced Personnel and Refugees
  5-20. DPs and refugees are excellent sources of information about denied
  areas and can be used to help identify threat agents and infiltrators. The
  degree of access HUMINT collectors have to DPs is dependent on the
  OPORDs, ROE, and SOFAs in effect. HUMINT collectors can work with CA
  or other programs dealing with DPs or refugees.
  5-21. DPs and refugees are normally considered one-time sources but may be
  incorporated into other long-term collection programs if their degree of
  knowledge warrants this. In this case, adherence to the restrictions involving
  source operations is necessary. Those restrictions can be found in AR 380-10,
  AR 381-100 (S//NF), DIAM 58-11 (S//NF), DIAM 58-12 (S//NF), and other
  publications as well as existing ROE and SOFAs.
  US Forces
  5-22. US forces have many opportunities to interact with the local population
  in the normal course of their duties in operations. This source perhaps is the
  most under-utilized HUMINT collection resource. Some US forces, such as
  combat and reconnaissance patrols, are routinely tasked and debriefed by the
  appropriate level G2/S2. Others, such as medical teams or engineers who
  have extensive contact with the local population, should also be debriefed.
  5-23. Commanders and staff members who serve as liaison with the local
  population and local government officials can be fruitful sources of
  information. CA, PSYOP, MP, and other elements also have legitimate
  reasons to conduct liaison with local authorities and should be debriefed as
  appropriate. The friendly force debriefing effort can succeed only with
  command emphasis.
  5-24. HUMINT collection elements need to coordinate with local units to
  identify those individuals who would be most profitable to debrief and to
  further coordinate with them for time to conduct the debriefing. Although the
  S2 and S3 can and should task their soldiers to conduct collection tasks
  during the course of their normal duties, HUMINT collectors must ensure
  that their friendly force debriefing effort does not interfere with the primary
  mission accomplishment of the soldiers being debriefed. HCTs should ensure
  that the necessary staff S2s and S3s are aware of the HUMINT collection
