I think I am going to play around with the stats for the spear using units this morning. Reducing their abilities in forests.

I was trying to think of what types of units would have difficulty in snow. I suspect all classes would be equally affected negatively by snow. I wonder if snow is an additional modifier over forest and scrub. We can have forest and snow simultaneously.

I was still wondering about the definition of scrub. So I opened up some scrub TGA files in the data\battlefield\vegetation file. It includes some tree and bush images. So I am guessing scrub are the maps with small trees and bushes that we have all seen from time to time.
