"Camouflage, concealment and deception
Full spectrum camouflage for combat clothing encompasses the ultraviolet, visible, (0.4 to 0.8 micron) near infra red (0.8 to 1.2 micron), and thermal far infra-red (2.0 to 5.6 and 8 to 14 micron)"[1]

Military Recognition of the Ultraviolet Sensor Threat
"Observation in the visual region, either by the eye, or by photography, remains the primary means of military surveillance and target acquisition. However, modern battlefield surveillance devices may operate in one or more wavebands of the electromagnetic spectrum, including the ultraviolet (UV), Near Infra Red (NIR), Far Infra Red (FIR). and millimetric or centimetric radar wavebands."[2]

The world's militaries have acknowledged the need for camouflage in the near-ultraviolet. For decades, NATO has mandated a highly ultraviolet-reflective white paint as ultraviolet camouflage for all vehicles used in snow conditions.
A 2012 study from Iran noted:

With development of the battlefield surveillance devices that operate in various waveband of electromagnetic spectrum, camouflaged munitions of soldiers should be protected not only in visible range but also should be concealed in wide spectral ranges, including ultra violet (UV), infrared (IR), radar, and so forth.[3]

The U.S. Army's "Soldier's Manual of Common Tasks - Skill Level 1" requires the soldier to learn to camouflage himself and his equipment from ultraviolet sensors and the U.S. Army Field Manual covering "Camouflage, Concealment, and Decoys" - FM 20-3 - warns the infantryman that ultraviolet sensors are a threat to guard against.

MIL-C-53004B, the U.S. Army military specification for camouflage systems requires UV camouflage, which only UVRC can provide.

Ultraviolet camouflage is necessary because of the variability of ultraviolet albedo - the percentage of ultraviolet light reflected from the soldier's immediate environment. Green foliage absorbs ultraviolet light, reflecting 7% percent or less, while the majority of the camouflage patterns, both for personnel and equipment, are significantly more reflective. Sandy turf, depending upon the silicates involved, may reflect as little as 3.3%, while many of the tans and grays used in camo are reflecting 50%+.
