Algodoo

A tank killer with four tires, a 94mm cannon, and a 7.8 millimeter machine gun.

It runs well, and has not failed me yet. It can go up a 25 degree slope easily. There's simple rough terrain to the left to test the suspension, and if I get a request for it, I'll add a tower to shoot.

The vehicle is actually pretty small (only about 2m tall), so it's not perfectly realistic, but it's close.
