Core Army Analytic Techniques 18 August 2014 ATP 2-33.4 5-29 Figure 5-19. Pattern analysis plot sheet example FACTS 5-115. In the example shown in figure 5-19, six enemy ambushes occurred in the first part of the month between 1800 and 1900. However, later in the month, two ambushes occurred between 1900 and 2000. This could indicate a shift in threat tactics, techniques, and procedures. Further analysis is needed to determine if that is correct. For example, a change in friendly operations may be the cause for the shift. The pattern analysis plot sheet is an effective tool in visualizing timeframes and types of enemy activity, but it must be used in conjunction with other intelligence to aid logical conclusions.
