PTM-4M

Also known as
  • ПТМ-4М
  • КБ ПТМ-4М
  • KPTM-4M

The PTM-4M is a Russian modernized PTM-4-family scatterable anti-vehicle mine with magnetic-influence fuzing and selectable self-destruct, designed for remote minefield emplacement from dispenser canisters and mine-laying systems. Human Rights Watch documented a PTM-4M-marked delivery canister in Kharkiv Oblast in May 2022, and OSMP later cataloged PTM-4M reports from Ukraine in 2023.

Role in Conflicts

Design Notes

The PTM-4M sits inside a remote-mining workflow rather than a normal hand-emplaced mine lane. The useful distinction is between the mine body, the canister that carries it, and the launcher or dispenser system that lays the minefield.
