that's not what i mean

you would have to add your own script lines like....
spawn vehicles/tigertank.tik
then give it a targetname and origin, etc.
how i do things like this is...open the tankbattle map in radiant. copy all the tank info down on paper. so when you spawn the tank, you do it from the script instead of in the map itself

then you check out and take what you need from the tankbattle scripts to make the tanks driveable

that is...if you make the mod server-side, which it sounds like what you want to do.
