The Schwerer Wehrmachtschlepper (sWS) ended up being made as a medium half-track and always transport materials to front-line troops or as a towing vehicle the light artillery. However, about the big back flat load compartment other applications have now been developed. One modification ended up being the Panzerwerfer 42 auf sWS, a 10 barreled 15 cm Nebelwerfer 42 rocket launched put over an armored ammo storage space compartment. The rocket launcher, developed as item to create smoke shows, have already been quickly used as genuine artillery in a position to introduce high-explosive ammunitions. It could shoot the rocktes with impressive and life-threatening outcomes. Initial framework of transportation car was in reality strengthened with additional shields to protect the team through enemy fire and from undesireable effects of rocket launcher.
