The German Waffentrager (weapon carrier), was formulated by the artillery and technical supply department at the end of 1942. It was assumed that two main types of carriers would be developed in parallel. The first one could be considered light and was supposed to mount a 75 mm PaK 40L/70 anti-tank gun, a 105 mm FH 18/40 howitzer, or a 37 mm FlaK anti-aircraft gun. The second type of carrier was intended for the more powerful 88 mm PaK 43 L/71 gun, the 150 mm FH 43 howitzer, and the 128 mm K43 gun.
The Schwere Geländegängiger Lastkraftwagen 4.5t Mercedes-Benz L4500A als Flakwagen was a self-propelled anti-aircraft gun (SPAAG) used by the German military during World War II. It was built by converting a standard Mercedes-Benz L4500A heavy-duty truck into an anti-aircraft vehicle by mounting either a 2 cm, 3.7 cm, or even a 5 cm anti-aircraft gun on the truck’s bed.
