I've drawn up a generic tank-engine. It looks pretty good but I need more information on scaling. I'm looking at some of the existing shp files to rob for turrets etc.
If any interested parties have top down views of rolling stock - esp armoured units but even flat cars and passenger cars would be good, I would love to see them.
Once I get a few more done, I'll post them as Icon0110.shp which remains un-used at the moment.
