You know Sunnyskies. He tries to mix it up. I never tried making a battle tank, so I gave it a shot. Here's prowler. It's small, but packed with features, including a modeled driver's and gunner's seat (don't expect to be able to see the road in that view), working turret with spotter camera and bridge-destroying main gun, working defensive machinegun turret, lights, a retractable antenna, and working entry hatches. I didn't feel like attempting to make actual tracks, so I stuck to what I knew. Wheels and suspension.

Here's how to work it:
AG1 engages the forward-gear. Watch your speed though, the Prowler gets tough to handle at excessive speeds.
AG2 engages reverse gear. Won't work well if your forward gear is still on.
AG3 unlocks the entry hatches, VTOL up to open them (but only do it when the turret is facing front).
AG4 turns on your headlights.
AG5 activates the machinegun turret (control it with VTOL and Trim).
AG6 unlocks the antenna (raise it up with VTOL).
AG7 is a junk slot for stuff you don't want to turn on (the lights in the cabin, and the exhaust ports). And
AG8 is what the main turret is bound to (control it and the spotter camera with VTOL and Trim). Happy hunting, tank commander!
