Panzerkampfwagen 38 für 2 cm Flak 38 (Sd.Kfz.140) Ausf.L ‘Flakpanzer 38(t)’

As in the later years of the Second World War, the Luftwaffe (Eng. German Air Force) began losing control over the sky and the German ground forces were subjected to increased Allied ground attack raids. Panzer divisions were especially affected by the lack of air fighter cover as they were always at the center of the most intense fighting. While the Germans already had copious amounts of half-tracked SPAAGs of different calibers and weights, they had a significant flaw of being themselves vulnerable to the planes they were meant to hunt. A tank-based anti-aircraft vehicle, a Flakpanzer (Eng. Anti-aircraft tank), could solve this problem, as it would have the armor to resist most aircraft armament. By 1943, the Flakpanzer IV was developed. Due to their rather slow development, the Germans were forced to introduce a temporary solution. This would lead to the creation of the Flakpanzer 38(t) in November 1943.
