  OTHER ANALYSIS TOOLS
  12-40. Pattern analysis is the process of deducing the doctrine and TTP that
  threat forces prefer to employ by careful observation and evaluation of
  patterns in its activities. This technique is based on the premise that threat
  COAs reflect certain characteristic patterns that can be identified and
  interpreted. Pattern analysis can be critically important when facing a threat
  whose doctrine is unknown and it is necessary to create new threat model
  and doctrinal templates. Three additional tools that can help the analyst to
  determine operational patterns and create and update their threat model are
  the coordinates register, pattern analysis plot sheet, and OB factors.
  Coordinates Register
  12-41. The coordinates register, or incident map, is one type of pattern
  analysis tool (Figure 12-5). It illustrates cumulative events that have
  occurred within the AO and focuses on the “where” of an event. The analyst
  may use multiple coordinates registers that focus on a different subject or
  blend subjects. Normally, the coordinates register includes additional
  information such as notes or graphics. The analyst should use the
  coordinates register in conjunction with the pattern analysis plot sheet.
