The German recipe's a bit of a word salad comment, so edited here for clarity: Prime with Vallejo Field Grey primer, drybrush Stone Grey over jackets and such.
Basecoat skin with AP Topaz Skin, bread bags and StG ammo pouches with VJ Khaki, water bottles with VJ Flat Earth, gas mask containers and mess tins in VJ Camo Olive Green, and any pack rolls with US Dark Green.
Rifles and wood with VJ Beige Brown, black leather and boots with VJ Black Grey, then brown leather straps and slings with VJ German Camo Black Brown.
Helmets with VJ German Grey.
White cloth basecoated in VJ Ivory, and finally black bits on weapons painted VJ Black.
Wash the whole thing in Sonic Tonic (link below), and highlight faces with GW Cadian Fleshtone then GW Kislev Flesh, highlight white cloth with either fresh VJ Ivory or VJ Off-White, and job's done.
