Thanks for the quick reply and the link. I tried adding your chief.ini file but I still get a CTD @ 70%

what you put into your chief.ini is correctly done..... BUT I noticed that there are certain vehicle types which cannot be added to a column....

I have noticed that. However the cars I added were copy/pastes from other columns that work so I don't see the problem there. Wait...could it be that you can't mix Red and Blue vihicles? Is it possible to add a Blue ZIS truck?
In the chief.ini file the ZIS5_AA is coded:

ZIS5_AA ai.ground.ChiefGround 1 icons/car.mat

Could I add:
ZIS5_AA ai.ground.ChiefGround 2 icons/car.mat

to this file? Or would that be a conflict?
