My friends team does as there secondary uniform.
they call it UDC (urban digital camo)
it works well on gravel roads, rubble and dark corners.

I believe there are 3 difference type of Digital Grays. ACU, UDC and there is a middle grey one in-between.
Not that i have ever seen it worn, just in a street market.
oh, there's also a Dark blue version, that I'm guessing might be navy.
