Finland has a great martial tradition, but keep it very quiet. Correct me if I'm wrong but, basically, during WW2, Finland was at war with the whole world. She originally defended herself against the Russia/Germany alliance but when Russia joined the Allies, Finland refused to allow Russia any part in the Alliance. No Russian was allowed in Finland. It was a very brutal war using avalanches as weapons.

For those reasons, if my info is correct, I'd suggest the Cameron's as the last official kilt of WW2.
