PRE-MOBILIZATION TRAINING ASSISTANCE ELEMENT (PTAE) 1. Select an OP. a. The site selected for an OP should provide— (1) Maximum observation of the desired area (specified by the platoon leader). (2) Cover and concealment for the occupants of the OP. (3) Concealed routes to and from the OP. b. Observation is the best way to determine whether the above conditions exist at a site. c. Usually, the best location for an OP is on or near the military crest of a hill. Topographical crests should be avoided because of the possibility of being skylined. It may be appropriate to establish the OP well down the forward slope when observation is restricted by the terrain.
