The FlaK series of guns have existed since the late Weltkrieg. The most produced design was the FlaK 37, serviced just before the breakout of the second one. It is an 88mm anti-air gun designed to spray air formations with shrapnel, even those at high altitude. However, the FlaK's very high muzzle velocity also make it an excellent anti-tank gun. In fact, most contemporary German anti-tank and even tank gun development dates back to the improvised use of 88mm guns againt Soviet heavy tanks. They were even used as light artillery in the absence of actual howitzers or field guns. FlaK 37s are fairly common in Oceanyka, being used in every role imaginable which requires a shell being thrown at high speeds somewhere.
