News Update #40: Firing High

The FLAK 38 was a 20mm cannon designed for anti-aircraft duty by the Germans in 1939. An improvement on it's predecessor, the FLAK 30, it fired a 20mm cannon shell at 220 rounds per minute and was extremely useful both in AA roles and in ground combat due to its high explosive shells.
