Verlinden 120mm British Paratroopers Arnhem - Colors?

Greetings.

The Verlinden figure set is of the British paratrooper carrying a wounded comrade.   It is one of those kits I wanted to wait until I had enough experience in painting faces before I ever tried to build it.   I have never attempted british uniforms before and want to get it right.   All the pics I have seen of this set seem to show the healthy paratrooper in a camo jacket and non camo trousers.   His wounded comrade seems to be in a khaki? battledress and trousers.   What colors should I use for the above?   I am open to either acrylic or enamel.   Also is there available any tutorials on the british patrooper camo style.

 Thanks

Steve
