Hi Rick,
Nice work. You seem to have finished the figure as a CSgt but used the Officers Head and Cap which doesn't seem right unless the RA SNCOs were different to the rest of the British Army.
He'll work as an ordinary soldier if you use a different head.
As far as I can remember only the badges of rank would be worn on the Greatcoat. Divisional signs etc were for Battle Dress Only.
I'd agree though it's a nice generic type figure with several uses.
Now someone can jump in and prove me wrong

Cheers
Al
