interesting how soldiers modified the bdu jacket by taking off the bottom pockets, adding velcro, slanting the pockets. Hell some people even rigged a sort of mandarin collar by adding velcro to the collar tips.
Then these features were added to the modern army combat uniform(ACU)
Guess it was tested as the CCU first though...
EDIT: this thread should help clarify, find pictures of the ACU/CCU yourself
