  • Distributed Common Ground System-Army (DCGS-A): DCGS-A is the
  ISR fusion and processing system for the future, as part of the
  overarching DOD-directed DCGS-A surface system family of systems.
  It will bring national and joint ISR capabilities down to JTF level,
  corps and division levels and BCT level to provide leaders with NRT
  information and visualization of threat, weather, and terrain
  information and intelligence. DCGS-A consolidates the capabilities of
  the following current-force ground processing systems:
   All-Source Analysis System (ASAS).
   Counterintelligence and Human Intelligence (CI/HUMINT) Single-
  Source Workstation.
   Tactical Exploitation System (TES).
   Guardrail Information Node (GRIFN).
   Guardrail Common Sensor (GRCS) Intelligence Processing Facility
  (IPF).
   Prophet Control.
   Joint STARS Common Ground Sensor (CGS).
  7-7. For more information on Intelligence Reach, see FM 2-33.5/ST.
  SOURCE-SPECIFIC RESEARCH
  7-8. Source-specific research is done immediately prior to questioning the
  source. The HUMINT collector may have to respond spontaneously in the
  case of a walk-in source in tactical operations, or if the HUMINT collector
  has advanced warning as in the case of a planned meeting with a source, a
  long-term debriefing, or an invitational source. Areas of research include but
  are not limited to––
  • Screening Reports, KBs, Other Reports: Reports about the source not
  only can provide specific information about the type of information the
  source can provide to answer specific collection requirements but also
  can give the HUMINT collector extensive background information
  about the source. This background information can give clues to
  information the source might possess and to possible approach
  techniques. Information contained in screening reports and KBs may
  provide insight into––
   Geographic Area: This area may show information about the source’s
  ethnic background, political affiliation, religion, and customs.
  Information can be obtained from databases, locally registered vital
  statistics, and residence registries.
   Languages: Determining the languages and dialects spoken, written,
  and understood by a source can provide valuable insights into that
  source’s geographic and ethnic or tribal background, education, and
  social status. This determination of languages and dialects can be
  facilitated by the use of “flash cards” specific to the battlefield.
   Other Reports: This can include other reports collected from this
  source at other echelons or reports from other sources from the same
  unit or location as the source. It can also include reports or
  documents published by the ACE at your request.
