Gator,
I am sure of this. Info came from a Marine I know that was part of the group that was looking into what type of cammo pattern to use for the uniform.
From how he explained it to me, the Army had been doing research into digital cammies before the Marines, but scrapped the idea cuz they couldn't get it to work well. When the Marines started looking for a look distinctly their own, after looking at several patterns, someone came across the discarded Army research and got it to work. The pattern they came up with is the one the Marines ar wearing now.
When the Army saw that the Marines got it to work, they went off of that. Developing their own pattern of course, but piggy backed off of what the Marines did to make the design work. The Army used a different colors and color ditribution scheme. The basic principle, however, is the same.
Not saying the Marines didn't get some help from the Canadians... but from my understanding, the basic idea came from some old US Army research that had been put out to pasture.
