Russian Sappers Use Smart Mines to Tackle Ukrainian Forces at Avdeyevka Front Line

"A crew of the advanced Zemledeliye (lit. Agriculture) remote mine-laying engineering system has laid smart minefields in the Avdeyevka area.

Equipped with seismic sensors and electronic chips, the mines [used by Zemledeliye] can detect the type of approaching target and are only triggered by strictly programmed targets, be it military equipment or a passing person.
Zemledeliye, which operates as a multiple-launch rocket system, is capable of firing 122mm rockets containing anti-personnel, or anti-tank mines, at a distance of up to 15 kilometers away. A single salvo from Zemledeliye can transform several thousand square meters of land into a deadly minefield." Sputnik
