The article reads like some articles I got from my hema buddies years ago.
I never was into Harnischfechten since it's more a thing for chaotic battles while I always were more the one-on-one guy and the forearms as well as the head are about the most important thing there since they are usually the only parts in range of your opponent. Every piece of armour is slowing you down as hell while evasion is always the better way with or without armour.
monkeydelarge: The ancient Celts would discourage their enemies with their private parts. Seriously. They were some crazy mother fuckers.
Maighstir: Playing bagpipes like the scots may also work... of course, they're largely descendants of the celts.
Only that the Scots were about the last culture to include the bagpipes, they are more a symbol of the middle east and Europe (especcially France) when it comes to tradition. The only reason why bagpipes are associated with Scotland today is the military.
