The need for such tactics in World War II became obvious from the noticeable smoke signature produced by the use of anti-tank infantry weapons such as the M1 bazooka, Panzerfaust and Panzerschreck, and also by the various models of Nebelwerfer and Wurfrahmen 40 German barrage rocket systems.
Dozens of F-8s served as various testbeds for anti-tank armament, including the WGr.28 280 mm air-to-ground missile, probably based on the projectiles from the Nbw 41 heavy ground-barrage rocket system, and the 88 mm (3.46 in) Panzerschreck 2 rockets, Panzerblitz 1 and R4M rockets.
