And what is their role, specifically. Cav is like LAVs and tanks, right? I've also heard of cavalry being light air units, like Kiowas. Another question, if there is an infantry unit that is supported by a cavalry unit, how does that work? Wouldn't it take a heck of alot of LAVs to transport a battalion or even company from point a to point b? The origional push to Baghdad comes to mind. Thanks for any input.
