Notes: This is the standard South African self-propelled howitzer, and is also in service with Oman and the United Arab Emirates. It is a standard NATO-pattern 155mm howitzer on a wheeled chassis, as wheeled vehicles use less fuel than tracked vehicles. The G-6 uses the same howitzer as the G-5 towed howitzer. The G-6 has a fire control computer that takes into account weather and other variables. The G-6 is able to compute a firing solution without an FDC. The driver sits at the front between the two front wheels, and the rest of the crew is in the turret. The turret has two hatches on the roof and a door on the right rear of the turret, and two firing ports on each side of the turret. The G-6 is equipped with a 34kW APU to power the systems when the engine is off. A modified version of this vehicle has an L/52 gun for added range.
