Catchy name don't you think? No, TSD is not going to make or sell clothing. Tried that when we sold Woolrich and 5.11 and it is too much drama for what it is worth. The matter at hand arose this last weekend when we held the Small Unit Tactics class in Kingman, AZ.
We had twenty guys attending. Some wore the very popular and effective Multicam camouflage. A couple of guys wore some derivatives of MARPAT, ACU, and various other "Green" camo. And we had several that were wearing civilian outdoor clothing, but in what I would term "muted earth tones". These were various shades of drab green, gray, brown and tan. Nothing blue or red - nothing white or black. And the tans were more brown than sand...so they were not "light".
This is not Urban camo to blend into groups. The objective is to sport a drab colored image based on shades of grey, brown, green, tan. Nothing blue...nothing red...nor any derivatives such as bluish grey or pinkish salmon. The idea is that the clothes blend into the woods/weeds, yet can go into the city as well. The wood/weeds takes precedence over the city in terms of colors.
Patterns would also be contraindicated unless there are plaid plants or stripped trees in your AO.
In any case we had students do a walk back from 100 to 350 yards as the other students watched them for contrast, effectiveness in blending with the area, and how easy it was to see them. Not scientific I suppose, but good enough for what our purposes where.
Anything moving is easy to see as nothing moves like a man. As well, a human head is distinctive and different from anything in nature. But aside from that what the class saw was that the Hippy Earthtones difused light and allowed the wearers to be nearly as "camouflaged" as the multicam wearing guys. Don't believe me? Ask they guys in class that saw what I am writing about.
The advantage of the Hippy Earthtones over the Multicam is this. If it is probable that one may need to go from rural weeds to city streets and back, the multicam would be contraindicated as while it would camouflage well in one zone, it would call attention to the wearer in another. The Hippy Earthtones would work well in both.
