This SPG is heavily inspired by the SU-5-1 and has a large howitzer as a main gun, this weapon is capable of penetrating many heavy tanks, heck, the gun alone weighs 4 tons, all the while having thick armor. With it's weight distrubution, the handling on this thing can be more like a car than a tank at times, not to mention it's overpowered engine from heavier SPGs. But all this handling and acceleration comes at a price, the SPG doesn't stop turning right away without brakes, this however applies only if you are moving and turning at the same time, and the lack on horizontal movement on the main gun means that you can miss your shot by a few feet, so it is recommended that you brake when you stop turning. Keep in mind you need tracks 2 to use this, I will be coming out with a non modded version that uses wheels instead. Vtol controls the howitzer elevation while trim + group 3 opens the seat compartments. In order to aim the gun you have to move the entire SPG. group 4 activates the machinegun, group 2 activates the winch, group 1 the magnet, and 5 the headlights, for night movement of course.
