When playing yesterday, I was able to train machine guns without rifling researched. And I though it has no logic to have machine guns without knowing to build rifles first. Its just observation, I don't know if you intended this to be like that. So everyone had musketeers and i had a nice defence of machine guns on all of my border cities...
Just checked vanilla BtS and it's the same: machine guns require only Railroads. I agree it's funny, but I guess they did it because of balance issues.
