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.
