These are from the Flames of War British Parachute Company but I'm not a history buff and I'm doing my best with the colors I have to approximate their uniforms.
Pants - VMC German Camo Pale Brown
Smock - VGC Khaki
Webbing / Gators / Helmet - VMC German Camo Bright Green
Boots / Gun and Helmet Straps / Metal Gun Bits - VMC Basalt Grey
Rifle Stock - VMC Leather Brown
Skin - VMC Basic Skin Tone
Everything was washed with a 50/50 mix of Pro Acryl Brown Wash and GW medium. On the first batch of these models I did this twice.
Pants and Webbing etc. were highlighted by mixing the base color with VMC Stone Grey.
Smock was highlighted the VMC Stone Grey.
Skin was highlighted with the base color.

The black bits weren't highlighted.
The metal bits of the guns were painted with VMetalC Gunmetal Grey.
