The German 88mm anti-aircraft gun mounted on a prime mover. It was the most effective all purpose artillery of the war. It was an excellent anti-aircraft gun but unlike others of its kind in Allied armies, it also could fire at 0 angle, allowing it to engage ground targets. It was ideal for dealing with tanks and other vehicles and caused much trouble for the allies, destroying 1000s of vehicles. It's range far exceeded any opposing gun. The gun was also mounted on tanks. It was unstoppable.
