The old M-1975 is the upgrade of the Field Gun, 150mm, Model 1945, making this the Grande Dame of the artillery, delivering the heaviest punishment to the enemy from far, far away. Due to its size, the field gun has to be towed by an external power - while horses are possible, trucks are usually preferred. The SDF-Army is looking for a replacement.
