POMZ
The POMZ, POMZ-2 and POMZ-2M (ПОМЗ, ПОМЗ-2, ПОМЗ-2М) are three types of Soviet-made stake mounted anti-personnel fragmentation mine. The POMZ mine was used during the Second World War. It was superseded by the POMZ-2, and later by the improved POMZ-2M. These mines (and copies thereof) have been used in numerous conflicts, including the Vietnam War and the Korean War.
