Hi guys. I noticed that if you sigh up for sega's "warroom" you will get access to the 10th Hussar unit (available for Britain). They cost 860 and gamewise, they are like mounted chassuers. They do have 125 range but don't expect any wonders as their accuracy is rubbish (35) and the reload is even worse. Considering their melee stats, you're better off getting dragoons. On the other hand, you don't have to fork out $$ for the dlc's sega trying to get you to buy in order to get extra units.
Anyway, you just need to sign up for the warroom (just the email needs to be a real one) and they will send you a code after you activate your account via email.
