FM 3-22.1Figure 7-9. Turret position indicator.Figure 7-10. Azimuth indicator.b. Target Reference Points. Leaders designate natural or manmade terrain featuresas reference points. The gunner uses these reference points to acquire targets and todetermine range during limited visibility. Predesignated TRPs must be visible to be usefulas TRPs or indirect-fire targets. The leader should always designate at least one TRP thatthe gunner can see on low magnification.(1) The commander or platoon leader designates indirect-fire targets used as TRPs sothat he can assign them target numbers. If TRPs fall within the sector of fire, the BCpoints them out and gives the gunner their designated reference numbers. Leaders shouldselect heated objects to use as TRPs so that the crew can acquire them withthermal sights.(2) Each gunner has at least one but no more than four TRPs. Because theinformation on a range card quickly gets crowded, it should only include pertinent datafor reference points and TRPs.c. Dead Space. Dead space is any area that the crew cannot observe or cover bydirect-fire systems within the sector of fire. Leaders must identify all dead spaces withinthe sector of fire, so the BC and platoon leader can plan how to use fires, such as mortars7-22
