The 28 and
32 cm rockets could also be fired from their packing cases (Packkiste) which had short hinged legs to adjust elevation. They could also be mounted in groups of four on wooden (schwere Wurfgerät 40 - heavy missile device) or tubular metal (schwere Wurfgerät 41 (sWG 41)) launch frames. The external dimensions of the packing cases were identical so no adapter was needed for the smaller rockets. The packing cases could also be mounted on schwere Wurfrahmen 40 (sWuR 40) frames attacked to the sides of Sd.Kfz. 251/1 half-track armored personnel carrier or various captured French tracked vehicles. The sWuR 40 was nicknamed the Stuka-zu-Fuß (Stuka on foot).
