Leer-2 electronic warfare system

Also known as
  • 85Ya6 Leer-2
  • 85Я6 Леер-2
  • Tigr-M MKTK REI PP
  • MKTK REI PP Leer-2
  • Leer-2E

The Leer-2 is a Russian mobile electronic warfare system installed on a Tigr-M 4x4 armored vehicle and built for radio reconnaissance, signal emulation, and jamming of enemy communications. Open sources describe a compact two-operator mission system with roof-mounted antennas, while Ukrainian reporting documents a Russian Leer-2 detected and destroyed in the Donetsk direction in November 2023.

Mission Equipment

Leer-2 combines an armored Tigr-M vehicle with a compact electronic-warfare package for finding radio emitters, measuring and recording signals, emulating radio-electronic systems, and jamming selected communications bands. Public descriptions emphasize mobility and short exposure near the front rather than a stand-off trailer or fixed-site layout.

Electronic attack role

Army Recognition describes selective and wideband jamming against VHF, cellular, and trunking communications systems.

Emitter intelligence

The same profile lists search-direction finding, recording, and parameter measurement for standard VHF, cellular, and trunking radio signals.

Mobile antenna fit

The Tigr-M installation carries its electronic-warfare antennas on a roof platform and can operate while moving or from a static position.

Variants

Public references treat Leer-2 as a Tigr-M-mounted EW system, with an export designation and a reported alternate KAMAZ-4350 truck installation.

Specialist references describe the main Leer-2 package as electronic-warfare equipment integrated into the Tigr-M armored vehicle, with roof-mounted antennas and onboard technical-control, electronic-intelligence, countermeasures, communications, power, and software equipment.

Open reporting describes it as a phased-array artillery reconnaissance system on a BAZ-6910-025 8x8 chassis, built to track incoming shells or rockets and calculate artillery firing positions for counter-battery fire. Russian state-linked reporting announced its use with Russian artillery units in Ukraine in January 2024, while Ukrainian military, government-linked, and independent news coverage later documented the destruction of multiple Russian Yastreb-AV systems.
