The Panzerfaust at home; Sweden was desperately requiring additional anti-tank capability especially seeing how advance tank warfare has become post-war and thus the Pansarskott was born.
It's basically a Panzerfaust with a safety. Pull the safety pin, aim, then fire. Backblast is evil.
There are M/46 and the M/50, which the M/50 has a better penetration and so forth as an improvement to the old M/46.
