D-27: Drawing an Observation Post Sketch

Previous: D-26: Manning and Equipment at the Observation Post

D-27. Once the leader has established the observation post he prepares a sketch. This sketch is similar to a fighting position sketch but with some important differences. Figure D-5 (page D-12) shows an example observation post sketch. At a minimum, the sketch should include:

  • A rough sketch of key and significant terrain.
  • The location of the observation post and alternate observation post.
  • The location of the hide position
  • Routes to the observation post and fighting positions.
  • Sectors of observation.
  • Direct and indirect fire control measures.
