Radar and terrain

[Blammo]

Change the way radar works so that it is based on line of site to the radar tower (as it would be in reality).  That would allow terrain to server some other purpose than eye candy.  Mountains, valleys, etc, would all effect what radar could see.

I don't know how many missions in R/L relied on the ground features to obscure their approach from Radar. But they were plenty.

I can see this making a patrol much more useful.
