Limey is correct... the early Soviet NVDs (gen I/II) image/light intensifiers used a mesh or grid style photoctahode. After a few years they caught up to western microchannel plates and cathodes that used coatings instead of mesh. This made the night camo parka and pants stand out like a fart in church.
I bought a parka, liner and pants for $20US in Kentucky back in 1993. That surplus dealer had a tractor trailer full of them. They are a little more expensive now i think.
A boonie was also made in the pattern; they're very hard to come by. I saw a BDU-style jacket and pants set a little while back (made by Cal-Pacific Mfg.), but those may well be a commercial item as the NSN listed on both the jacket and the pants were for the six color desert pants.
I had a set of those issued to me when I did peackeeping duty in the Sinai in 1986.
Sometime ago I read a story that some US soldiers actually put this theory of their effectiveness to the test during the 1992 Gulf War. They got hold of some Iraqi NVDs (Soviet Aid) and discovered that this grid-matching stuff was a load of crap. They said that guys wearing these night parkas were actually MORE visible through the NVDs than if they were wearing day desert uniforms.
