ULTRALIGHTWEIGHT CAMOUFLAGE NET SYSTEM (ULCANS)
ULCANS is the camouflage system designed for use with all military materiel including tactical vehicles and aircraft. ULCANS is the only camouflage screen system employed by aviation units to camouflage aircraft. It is intended to increase vehicle survivability by countering visual, wide band radar, near infrared and thermal detection capabilities. During high winds and heavy snowfalls, ULCANS should be checked frequently. A great accumulation of snow or ice should not be allowed to accumulate on screens. Snow or ice must be removed from the screens as soon as they begin to sag or show signs of stress or strain due to the extra weight.
