I think 21C had a Russian woodland camo uniform in a figure that didn't get wide release. There was a thread recently that mentioned it, try searching forum. It's more than likely extremely hard to find. Don't know of any other available.
Armoury produced a very nice woodland flecktarn uniform on one of their modern German figures. It's long out of production and quite rare, you might try searching the eBay vendors listed on the forum for loose pieces or a boxed set.
You'll have better luck with finding this. There are a few sets of the Crye around, some with boots, weapons, body armor, etc. Again try the eBay vendors that are listed in the forum. Ironcrosshunter lists one for instance.
