Section III. OPERATION UNDER UNUSUAL CONDITIONS
2-4. OPERATING UNDER UNUSUAL CONDITIONS.
Operation under unusual conditions includes deployment in inclement weather and retrieval in
emergency conditions. When operating in unusual conditions it may be necessary to use longer
stakes to accommodate soil or other varying conditions. Additional stake NSNs can be found in
Appendix E, Additional Authorization List.
WARNING
When using an ULCANS multi-screen configuration (of 8 ft high or
more), camouflage screens can be blown down when winds exceed 46
miles per hour. Damage to equipment may result. When winds in
excess of 46 miles per hour are expected, screens shall be lowered and
secured.
When heavy freezing rain, sleet or snow is expected or occurring, screens shall be
lowered and secured.
CAUTION
In desert environments, the support poles and metal stakes left in direct
sunlight can become extremely hot to touch. Wear gloves to prevent
burns.
a. Inclement Weather.
(1)
When high winds in excess of 46 miles per hour are occurring or are expected,
the ULCANS should be lowered and secured. During gusty windy conditions
frequent checks should be made to ensure that stakes and tiedown points remain
secure to prevent billowing and sagging.
(2)
When heavy freezing rain, sleet or snow is expected or occurring, screens shall
be lowered and secured. During inclement weather conditions such as snow,
rain, and sleet, more frequent checks should be made for signs of stress or
strain.
b. Emergency Retrieval:
(1)
Remove camouflaged item(s)/vehicle from underneath ULCANS prior to retrieval
when possible. If removal is not possible and separation of multiple screens is
not required, then support poles and shape disrupters should be removed from
underneath and away from camouflaged item(s)/vehicle to prevent damage or
injury to personnel during retrieval. Remove all ground stakes. On large
vehicles such as trucks, tanks, Patriot Missile system, or Stinger Man-Pads, etc.
it may be easier to keep ULCANS pre-attached, rolled, and secured to the top or
side of vehicle.
