CoClasses and Classes Description
FEGraphic A cached graphic that symbolizes a point based military object (feature or force element).
TacticalGraphic A cached graphic that symbolizes a point, line, or polygon based tactical military object (feature or tactical element).

Remarks

MOLE force element and point tactical graphics support direction information.  This information can be used to draw direction of movement modifiers/indicators for those kinds of cached graphics.

Direction is a value from 0 - 360 and when direction is drawn/displayed as an indicator the direction is assumed to be a compass/navigational direction (0 is north, 90 is east, 180 is south, 270 is west).
