The Stockmine ("stick mine"), also Betonmine ("concrete mine"), was a German anti-personnel stake mine used during the Second World War.
It consisted of a cylindrical concrete main body on top of a short wooden stake.
The concrete head contained a small TNT bursting charge, and was embedded with a number of metal fragments.
A number of copies of the mine were produced after the war by different countries including the Cuban PMFC-1, the Czechoslovakian PP-Mi-Sb, and the Yugoslavian PMR-2 which is found in Bosnia and Croatia.
