B-36. A TRP is a recognizable point on the ground leaders use to orient friendly forces, and to focus and control direct fires. In addition, when leaders designate TRP as indirect fire targets, they can use the TRP when calling for and adjusting indirect fires. Leaders designate TRP at probable enemy locations and along likely avenues of approach. These points can be natural or man-made. A TRP can be an established site. For example, a hill or a building, or an impromptu feature such as a burning enemy vehicle or obscurants generated by an artillery round can be designated as a TRP. Friendly units also can construct markers to serve as TRP. (See figure B-4.) Ideally, TRP should be visible in three observation modes (unaided, passive-infrared, and thermal) so all forces can see them. Examples of TRP include the following features and objects:
- Prominent hill mass.
- Distinctive building.
- Observable enemy position.
- Destroyed vehicle.
- Ground-burst illumination.
- Obscurants round for immediate engagements only; this is the least preferred method.
