  the AO. In order to accommodate the differences in the screening audience
  and location, different types of source screening operations are employed.
  • Tactical Screening. Tactical screening is conducted in support of
  combat or contingency operations. It can include the screening of
  EPWs or detainees at the point of capture, the screening of refugees, or
  the screening of local civilians in cordon and search. At the tactical
  level, there is no time for elaborate approach techniques so the degree
  of cooperation becomes a prime concern. Tactical area screening is
  characterized by rapidly changing requirements, the need to evacuate
  noncombatants and detainees to a secure area, and the need to collect
  priority tactical information while operations are in progress. Although
  the most lucrative type of source is often the detainee, all available
  sources should be screened for priority tactical information. In tactical
  screening, the HUMINT collector normally accompanies the maneuver
  force (OPCON or DS). If the HUMINT collector establishes that the
  source has information of value during screening, he immediately
  questions the source. Information collected is passed to the maneuver
  commander, normally via SALUTE reports. The HUMINT collector
  may recommend to the commander that individual sources be further
  detained for additional questioning. Screening must be done accurately
  in order that a commander can make a decision to detain or release
  possibly hostile personnel, based on the recommendation of a HUMINT
  collector.
  • Checkpoint Screening. Checkpoints are often established to screen the
  local populations as they transit through and within the AO or to
  screen large numbers of individuals such as refugees or DPs as they
  enter the AO. Screening checkpoints can be static or mobile. HUMINT
  collectors must pay particular attention to refugees leaving the area
  ahead of friendly forces (AO or AOI). It is likely that refugees can
  provide information of tactical value more quickly and easily than
  detainees. Refugees know the area and may be able to identify for the
  collector anything that is out of the ordinary, such as insurgent or
  terrorist activities.
  • Local Population Screening. This refers to the screening of the local
  population within their own neighborhoods. When HUMINT collectors
  move into a new area, they must observe the local population and
  determine who may be able and willing to provide the information they
  have been tasked to collect. Once this determination is made, the
  collectors must engage those individuals in conversation to assess their
  level of knowledge.
  • Collection Facility Screening. Screening is conducted as a normal part
  of HUMINT collection operations at collection facilities such as theater
  interrogation and debriefing facilities and refugee camps. Screening is
  coordinated with the unit, normally an MP unit that is responsible for
  the operation of the facility.
  • Local Employee Screening. CI personnel periodically screen local
  employees to determine possible security risks. Concurrently, local
  employee screening may identify sources who can provide information
  to answer the CCIRs. Close coordination between HUMINT and CI
  collection assets is a must in local employee screening.
