Though I'd better make a note of this before the grey matter looses the info:
Skin was 'flat flesh', washed with some thinned down very old citadel purple ink. highlighted 'flat flesh' & ' light flesh'.
The webbing was base coated 'Russian tank crew' or 'Russian uniform', and highlighted with 'khaki', then washed with 'olive green', the respirator bags were washed with 'Luftwaffe green'.
The battle dress was 'English uniform' shaded with 'German.cam black/brown'.Highlighted with 'English uniform' & 'khaki'.
The smocks where 'dark sand' with a little 'red leather' then a very thin wash of 'red leather'.
The green blotches were a mix of approx 60% 'olive green' & 40% 'ocher brown'.
The brown blotches were roughly 50/50 'hull red' & 'German cam. medium brown'
Pretty much the whole thing, uniform & webbing was dry brushed with 'khaki'.
