Solothurn S-18/1000

The Solothurn S18-1000 20 mm was a German anti-tank rifle designed and manufactured in Switzerland and used during the Second World War. It was a variant of the earlier S-18/100 with modifications for a higher muzzle velocity, as well as a larger cartridge size. The more powerful ammunition resulted in significant recoil, which was problematic for the gunner, and its size made portability difficult.
