In the later stages of the Second World War, the Germans lost control over the skies, and their ground forces had to endure extensive enemy air attacks that decimated German logistics. The use of self-propelled anti-aircraft guns based on half-track chassis offered some way to fight back, but these were themselves highly vulnerable, as they lacked proper armor protection. Because of this, armored anti-aircraft vehicles based on a tank chassis were desirable. Starting from 1944, the German focus was on producing such vehicles based on the Panzer IV chassis, which led to the development of the Flakpanzer IV 2 cm (0.78 in) Flak 38 Vierling, known as the Wirbelwind (Whirlwind). Its 3.7 cm (1.45 in) armed Ostwind (Eastwind) cousin sacrificed a higher rate of fire for a heavier punch.

![Kit Bashing Down Under | Matilda Frog, Matilda Dozer and Matilda Hedgehog in Australian Service
In a recent video, we covered the history of the British-built Matilda II infantry tank in Australian service. Arriving in mid-1942, the 200 tanks imported straight from the British Empire made up the core of the Australian armored forces until the end of World War II, and were praised for their compact size and extraordinary durability in the face of enemy fire. But fighting in the Pacific theater was anything but conventional, and required both new tactics and new equipment to be rapidly developed and rushed to the front lines. Today, we’ll be discussing the three major variants of the Matilda II design that emerged from this environment; the Matilda Frog, the Matilda Hedgehog, and finally the Matilda Dozer.
