I agree with the fact this is the most requested thing. Hopefully some day someone will make it, since they have homing projectile scripts now. Missile battery Anti-Air vehicles can be possible, this would be amazing for servers. A simpler tank shell styled artillery would also be very nice. Try and get a hold of some vehicle modders, i'm sure you'll get someone to do this. That and more tanks, Blockland lacks realistic tanks (that are released).
