Show all enemy graphic control measures in red. The red symbol represents enemy installations, equipment, and activities.

The yellow symbol represents any areas of chemical, biological, and radiological contamination.

The green symbol represents any man-made obstacles. Show all obstacles, friendly, enemy, or neutral in green.
