I got my self a box of 40 Soviet soldiers and the army book for the Soviets and I have painted a test models after looking for some colour choices of the Soviet uniforms.

These are my three steps when painting this model;

1. Base colours
Uniform - Grey Khaki
Wood - Deathclaw Brown
Bedroll etc. - Flat Earth
Gun barell - Adeptus battlegrey

2. Highlights
Added a mix of base colour and white mix of a 1:1 ratio.

3. Wash
Uniform & Bedroll etc. Wash - Quickshade Strong
Gun barrell Wash - Heavy Badab black
Wood - Baal Red
