Hi Mike

Thanks for the comments, the green is Vallejo 080 German cam bright green which I added some 017 Basic skin tone to lighten it further (I like to start with very light paint tones) then washes of Burnt umber and filters of Humbrol 62 matt chocolate toned the colours down to a bit more of a scale tone.Then came some chips and scratches using a fine brush.
Hope this helps
Lester
