S-mine
This Anti-Personnel mine is the most widely known and most deadly of all. It is about 6 in. high and 4 in. in diameter, usually fitted with the 3-pronged “S” Mine igniter 35. The mine is buried in the ground with Just the prongs of the igniter above ground.
When stepped on, the igniter sets off a booster charge which pops the mine, out of its metal case about four feet in the air where it explodes, scattering 350 steel balls in all directions, deadly up to at least 100 yards.
