For my future reference, this was the paints I used:
Tamiya Matt Black undercoat
Atelier Raw Sienna Dark - leather
VJ Medium Flesh
Citadel Shade Reikland Fleshshade
Jo Sonja Olive Green - pants
VJ Oily Steel - metal
Jo Sonja Green Oxide - pant highlights
Jo Sonja Burnt Umber - sandals (impressionist)
Tamiya Flat Earth - base
Jo Sonja Yellow Deep - shield
Working within the limitations of the figures I was lucky they had not gone brittle. That allowed me to reposition the shield arm. The flesh shade worked really well which was a surprise as I didn't think the figures had much detail to be accentuated.
I'm not totally happy how the shields turned out, but they will do for now. I like the yellow and black signifying "danger" as a colour scheme.
The next thing for these guys is a Impetus size movement tray and maybe some markers for opportunity, disorder and casualties. I'm thinking green (for go), light brown (for dust) and red brown (for blood). Could just go with green, yellow and red.
Amazing - these figures are almost 50 years old.
