This wonderful and weird disposable "RPG" was developed and produced in the late 70s/80s in Czechoslovakia and is still in use today by the Armies of the Czech Republic and Slovakia. It is similar both in use and function to the American M72 LAW.
This model was created in 3DS Max, textured in Substance Painter. There was also a bit of photogrammetry used for the trigger mechanism and the paper stickers. It was created for the mod RHS: Green Forces.
