The Behelfs-Schützenmine S.150 was an anti-personnel mine that was developed by Germany and used by the Wehrmacht during World War II.

The body was cylindrical in shape and was made from pressed steel or aluminium and contained an explosive charge of powdered picric acid.

[1] The igniter was aluminium and contained a glass ampoule, half-filled with sulphuric acid, and surrounded by potassium perchlorate flash powder.

[2] A weight of 16 kg (35 lb)[3] crushed the igniter, broke the glass ampoule and allowed the acid to mix with the flash powder.

Disarming one was a fairly simple procedure of unscrewing the igniter near the base, avoiding the fragile top.
