Make the # to same as the mobile artillery, this will make it so you can drive the mobile turrent for a while, but so you cna't use it to attack, just deffence. Whent he mobile aritllery explodes, the turrent will hover there. And make sure the mobile artillery and turrent are suing a different ID.

I made a script mod befor mod toosl came out doing this..

And 1300 frames will make it so you can get the mobile artillery about half-way up the hill on feild.
