Space/Click In 2032 we got the I-2 Mustang Tank. It sucked. A lot. So in 2033 we made the I-3 Cobra. The I-3 was much better than the I-2, but still had some issues. It's color wasn't the best and it's machine gun was mid. So, in 2034, it's time to make the I-4 Top Speed: 55 MPH (I-3 Top Speed: 50 MPH) 30 ft long barrel 120mm heavy cannon 25mm machine gun Advanced Composite Armor 300 Mile Range Cost: $3,100,000 USD per unit (not for sale yet though) The I-3 will not be retired like the I-2, but will be available to purchase ($3,012,000 USD per I-3)
