Flakpanzer

A flakpanzer is like a big vehicle with lots of guns on it that can shoot down planes and other things that fly in the sky. It's like a special tank with lots of metal bullets that come out really fast and can hit airplanes or anything else that is up in the air. So, if there are bad guys flying planes or dropping bombs, the flakpanzer can shoot back and protect the people on the ground. It's like having a big gun on wheels that can move around and shoot in any direction.
