Cossack Invasion for WFAS

[MadScotsman]

I had this idea while playing WFAS with a couple of mates, i already have the class ideas.

Duelist OR Pirate: Uses: Pistols, Swords and has lighter armor
Infantry: Exactly like NI but doesn't use as many shields.
Grenadier: Has Grenades but only a dagger to defend himself, has more heavier armors than the Duelist but less than an Infantry
NEED A NAME: Uses more primitive weapons like bows and can run faster

Any ideas? Throw them at me i'll add to it!
