MON-50

Also known as
  • MON 50
  • МОН-50
  • Mina oskolochnaya napravlennogo deystviya

The 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.

Role in Conflicts

Side
Russia

Russian forces and Russian-backed armed groups have used MON-50 mines in Ukraine across both phases of the war. Landmine Monitor 2015 cited Spartak Battalion emplacements with MUV fuzes and tripwires near Marinka, while Human Rights Watch and current Landmine Monitor reporting list MON-50 among Russian-used antipersonnel mines since the February 2022 full-scale invasion.

Role in conflict
Tripoli antipersonnel mine emplacement

Human Rights Watch and Landmine Monitor identify Russian-origin MON-50 directional fragmentation mines, including examples with MUV-series tripwire fuzes, among the antipersonnel mines used or emplaced around Tripoli in 2019-2020 by Russian mercenaries backing Hiftar-aligned forces.

Variants

Public technical references distinguish the MON-50 mainly by its preformed-fragment load rather than by separate model designations.

Timeline

MON-50 Key Events

  1. MON-50 emplacements reported near Marinka

    Landmine Monitor 2015 cited a Russia 1 report showing Russian-backed Spartak Battalion members emplacing MON-50 mines with MUV fuzes and tripwires near Marinka in Donetsk province.

  2. Full-scale invasion expands Russian mine use

    Human Rights Watch and Landmine Monitor list MON-50 among Russian-used MON-series antipersonnel mines documented after Russia's full-scale invasion of Ukraine.

  3. HRW documents Tripoli MON-50 contamination

    Human Rights Watch reported that post-2019-2020 Tripoli clearance materials included MON-50 directional fragmentation mines among Russian-origin antipersonnel mines found after Hiftar-aligned forces withdrew.

Fragmentation And Initiation

MON-50 reporting often identifies the mine together with tripwire or MUV-series fuzing, so the body, fragment load, and initiation context are useful to read separately.

AreaSourced detailReader context
Directional bodyODIN and other technical references describe a hand-emplaced directional fragmentation antipersonnel mine with a plastic body and folding support legs.The shape and supports make the MON-50 a small placed munition rather than a buried pressure mine.
Fragment optionsPublic references list either about 540 steel balls or about 485 chopped steel rods as the preformed fragment payload.The two fragment loads explain why variant descriptions usually describe internal fragment fill, not a separate external model name.
Initiation contextConflict reporting identifies MON-50 mines with command or tripwire-capable initiation, including MUV-series fuzes in Ukraine and Libya evidence.That dual-use initiation is central to the antipersonnel-mine concern when the mine is configured for victim activation.

MON-100, Directional anti-personnel fragmentation mine, Infantry WeaponsInfantry WeaponsMON-100Directional anti-personnel fragmentation mineThe MON-100 is a Soviet/Russian directional anti-personnel fragmentation mine in the larger end of the MON family. Technical references describe a circular metal-bodied, stake- or fixture-mounted mine with a 2 kg TNT charge, roughly 400 steel fragments, and command or tripwire-capable initiation. Monitoring groups identify MON-100 use by Russian forces in the 2014 Russia-Ukraine War and by Russian mercenaries around Tripoli during the 2014 Second Libyan Civil War.
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-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.
