Why there's different banners

[Martok]

It took me only a minute to figure it out once I really *looked* at the screenshots, but I did finally realize what the different-shaped banners mean.

Horizontal rectangle= Cavalry
Vertical rectangle= Infantry
Triangular= Missiles (Archers, Javelins, etc.)

That's pretty neat. It's a nice, simple way to see at a quick glance approximately what units are on the battlefield--both yours and your enemies'. Nice touch, CA!

That's cool. Maybe each faction (or at least culture) got their own warhorns as well.
