You actually have the Canadians to thank for the new duds. The US Army gave up on digital camouflage almost 30 years back and no one was really considering it again until the Canadian Forces adopted the CADPAT digital camouflage in 1997-1998, the US Marines lifted it and changed it slightly to MARPAT (although they denied it was a copy) in 2000. Since it was cool, now everyone is starting to use it.
