PMN-1/2/4

Also known as
  • PMN
  • PMN-1
  • PMN-2
  • PMN-4
  • Protivopekhotnaya Mina Nazhimnaya
  • Black Widow

The PMN-1/2/4 family covers Soviet and Russian pressure-activated antipersonnel blast mines used to deny foot movement and injure personnel at close range. PMN-1 and PMN-2 are Soviet designs, while PMN-4 is a later Russian circular plastic-cased mine; conflict-use records now connect PMN-family mines to Ukraine, Libya, Nagorno-Karabakh-related minefields, and disputed PMN-2 incidents along the Thailand-Cambodia border.

Role in Conflicts

Side
Russia

Russian forces have used PMN-family antipersonnel blast mines in Ukraine, including PMN-4 mines cleared in Sumy Oblast in April 2022 and PMN-2 mines documented in occupied residential areas of Kherson Oblast.

Role details
Role in conflict
Antipersonnel area denial

PMN-2 antipersonnel blast mines were documented in southern Tripoli after the 2019-2020 fighting, with Human Rights Watch reporting Russian-made PMN-2 mines claimed as used by mercenaries supporting LAAF forces and later found by mine-action groups.

Role in conflict
Antipersonnel minefield and area denial

Post-2020 Nagorno-Karabakh-related mine reporting documented PMN-2 antipersonnel mines among Armenian-attributed mines found on territories and supply roads in 2022. Landmine Monitor noted the Azerbaijani claims and Armenia's denials, with confirmation limits outside Azerbaijani sources.

Role in conflict
Border-area antipersonnel mine hazard

Landmine Monitor and Reuters documented PMN-2 antipersonnel mines tied to the 2025 Thailand-Cambodia border crisis. Thai authorities attributed newly found mines to Cambodian forces, while Cambodian officials denied laying new mines; Reuters-cited specialists assessed photographed PMN-2 mines as likely newly laid but did not independently identify who emplaced them.

PMN Family Comparison

The three designations are grouped because public conflict reports often name the family while technical sources separate the generations by size and explosive fill.

DesignationDocumented distinguishing pointsConflict-use context in this record
PMN-1Early Soviet pressure blast mine, about 112 mm diameter with roughly 200 g pressed TNT.Included for family identity and technical context; the current direct conflict rows center on PMN-2 and PMN-4 examples.
PMN-2Later Soviet pressure blast mine, about 120 mm diameter with a 100 g TNT/RDX charge.Directly documented in Libya, Nagorno-Karabakh-related mine reporting, and disputed Thailand-Cambodia border mine incidents.
PMN-4Later Russian pressure-fired blast mine, about 95 mm diameter with about 55 g TG-40 explosive.Directly documented in 2014 Russia-Ukraine War mine-clearance reporting.

Timeline

PMN-1/2/4 Key Events

  1. PMN-1 generation

    The PMN-1 branch is described in the record's technical sources as the late-1950s Soviet pressure blast mine generation with the largest explosive fill in this grouped entry.

  2. PMN-2 generation

    The PMN-2 branch followed as a later Soviet pressure blast mine and is the variant directly documented in Libya, Nagorno-Karabakh-related reporting, and the Thailand-Cambodia border crisis.

  3. PMN-4 Russian generation

    The PMN-4 branch represents the later Russian member in this entry; U.S. Army ODIN lists its smaller body and TG-40 explosive fill.

  4. PMN-4 mines cleared in Sumy Oblast

    Human Rights Watch documented PMN-4 antipersonnel mines cleared in Sumy Oblast during the 2014 Russia-Ukraine War.

  5. PMN-2 border incidents reported

    Thailand reported PMN-2 mines during the 2025 Thailand-Cambodia Border Conflict; Reuters later published specialist assessments that photographed examples were likely newly laid, while attribution remained disputed.

MON-series anti-personnel mine, Directional fragmentation anti-personnel mine family, Infantry WeaponsInfantry WeaponsMON-series anti-personnel mineDirectional fragmentation anti-personnel mine familyThe MON series is a Soviet/Russian family of directional fragmentation anti-personnel mines, including MON-50, MON-90, MON-100, and MON-200 patterns that project preformed fragments across a defined sector. Monitoring groups identify the family in Russian mine warfare in Ukraine and in Russian-linked Tripoli minefields in Libya, while the Nagorno-Karabakh record is narrower and rests on postwar MON-50 clearance reporting.
MON-50, Directional fragmentation antipersonnel mine, Infantry WeaponsInfantry WeaponsMON-50Directional fragmentation antipersonnel mineThe MON-50 is a Soviet directional fragmentation antipersonnel mine broadly comparable in role to the M18 Claymore, with a plastic body, folding legs, and a forward fragmentation pattern. It can be command-detonated or configured with tripwire and other fuzing, making it a compact infantry obstacle and ambush munition. Direct monitoring sources document MON-50 use by Russian or Russian-aligned forces in eastern Ukraine, the full-scale Russia-Ukraine War, and the 2019-2020 Tripoli fighting in Libya.
POMZ-2, Stake-mounted antipersonnel fragmentation mine, Infantry WeaponsInfantry WeaponsPOMZ-2Stake-mounted antipersonnel fragmentation mineThe POMZ-2 is a Soviet stake-mounted antipersonnel fragmentation mine built around a serrated cast-iron body, TNT charge, and pull-fuze tripwire. Its simple above-ground layout made the mine a persistent legacy hazard: cataloged use now spans Soviet mine warfare in Afghanistan, Vietnamese forces in the 1955 Vietnam War, Nagorno-Karabakh stockpiles and defensive minefields, and a limited 2011 Syrian Civil War indication tied to Syrian government forces.
MON-90, Directional fragmentation antipersonnel mine, Infantry WeaponsInfantry WeaponsMON-90Directional fragmentation antipersonnel mineThe MON-90 is a Soviet-designed directional fragmentation antipersonnel mine and the 90 m member of the MON family between the smaller MON-50 and larger MON-100. Technical references describe a plastic-bodied, tree-spike-mounted mine with about 2,000 steel fragments, two M-10 threaded fuze wells, and command or tripwire initiation depending on setup. Direct monitoring sources place MON-90 mines in Russian use in Ukraine after the 2022 invasion and in Russian-linked Tripoli mine contamination during the Second Libyan Civil War.
