S-Mine

The S-mine was a German bounding anti-personnel mine used from 1935 to 1945, with more than 1.93 million produced. When triggered, a small propellant charge threw the mine roughly a meter into the air before it detonated at about waist height, scattering around 360 steel balls and fragments in every direction, a design meant to maim rather than simply kill. German forces relied on it as a core part of Wehrmacht defensive minefields in occupied territory, North Africa, and Italy, where more than 23,000 were laid in that country defense alone, and Allied troops who called it the Bouncing Betty or the frog mine came to regard it as one of the most feared devices of the war; several other armies later copied its design.
