AREA5

Anchor Points: This symbol requires three anchor points. Points 1 and 2 define the endpoints of the semicircle's opening. Point 3 defines the end of the arrow.

Size/Shape: Points 1 and 2 determine the diameter of the semicircle and point 3 determines the length of the arrow. The tip of the arrowhead will be at the center point of the semicircle's diameter and will project perpendicularly from the line between points 1 and 2. The default tic length should be the same as the text height of the echelon field (B). Spacing between the tics should also be the height of B. Users should be provided a facility to allow them to manually alter the height of B, which in turn should affect the tic length and spacing accordingly.

Orientation: The opening typically faces enemy forces.
