I'll answer in english, as internet translation may yield not so good results...
What do you mean with complete ?
The german flecktarn BDU has
Boots
Socks in grey or olive
Tshirt - olive
Feldbluse (Jacket)
Feldhose (Trousers)
Feldmütze (Cap)
Koppelgürtel (belt)
If you want more (like the complete webbing and combat equipment)
Flakwest (Splitterschutzweste)
Webbing (Koppeltragegestell) with
- NBC Mask with filter - (M65)
- Bottle
- Shovel
- Stuff you need to eat in the wild (Spoon, Knife, Fork, Esbit cooking kit, etc.)
Helmet
Gloves
Backpack
Sleeping Bag
Sleeping pad (Isomatte)
Tent
Flashlight
Raingear (Goretex)
Parka (Cold weather jacket)
This list is way from complete, but contains much of the stuff you requested.
For ordering such stuff, it is getting complicated.
You can go to
www.raeer.com or
www.ranger-shop.de
both offer international shipping into GB, but the sites are in german only...
Hope I could help.
