Well, there's always plenty of photos to look at on the Muttpage, but sometimes....a bit of useful information is welcome.
On this page, by popular request, we have a complete description of the US Military's 4-colour MERDC camouflage pattern schemes. These patterns were introduced in 1975 and continued until the introduction of the 3-colour "NATO" pattern in 1990.

As far as I am concerned, the 4-colour system was much more interesting and versatile than the 3-colour system in use now, but make your own mind up....................
