Chapter 5
Equipment Symbols

This chapter describes equipment, weapon, ground vehicle, and aerial vehicle symbols. It describes procedures for creating composite weapon system symbols and the procedures for text labeling to provide necessary details.

The use of the symbol frames shown in Chapter 4 is optional for equipment and recommended only for ships, aircraft, and aerial vehicles.

Orientation of the symbols shown in this chapter is extremely important. All manual and automated displays and overlays should show the symbol oriented the same as the actual equipment. The "Q" field will show the orientation of moving equipment symbols.

Blue or black will represent friendly equipment on color displays and red will represent enemy or hostile equipment. Monochrome displays will use the color available.


Figures 5-1 through 5-4 show the placement of unit labeling fields around the different symbol frames. Figure 5-5 is a table defining the labeling fields. See Appendix A for examples of fully labeled unit and equipment symbols.
