This has now been further developed into “transitional” environments and has become the third environment to match within the Phase IV Army program. These were two versions of tigerstripe and an older design of Rhodesian Brushstroke. MARPAT did exceptionally well in their wet uniform test when viewed with night vision while illuminated with IR, where normally patterns appear as a solid.
F This adds cost to the fabric and in some cases it works until washed, then you have a uniform that is worse in the NIR then it would have been had the NIR coating not been applied in the first place, I won’t name which country this occurred to.
