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 Ukraine-war evidence places Leer-2 systems in Russian electronic-warfare activity from Crimea and Ilovaisk to documented full-scale-war losses.
Jamestown analysis names Leer-2 among Russian electronic-warfare systems evident during the 2014 Crimea operation and included in EW assets around Ilovaisk, while Ukrainian and defense reporting later documented Russian Leer-2 losses during the full-scale war.
Role detailsLeer-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.
Army Recognition describes selective and wideband jamming against VHF, cellular, and trunking communications systems.
Army Recognition and VPK.name describe radio-emitter reconnaissance, recording, measurement, and suppression functions.
The Tigr-M installation carries its electronic-warfare antennas on a roof platform and can operate while moving or from a static position.
Russian-language product references identify the Leer-2 developers as LLC Military Industrial Company and VNII Etalon of Vega Concern. The equipment is tied to the Tigr-M armored-car chassis, while separate reporting links early Airborne Forces deliveries to the Arzamas vehicle-production base.
VNII Etalon is named in Russian-language references for the technical-control, radio-electronic emulation, and jamming package.
VPK / Military Industrial Company is identified with the Tigr-M vehicle side of the system, and the site has a dedicated builder profile for that armored-vehicle manufacturer.
The mobile 4x4 configuration supports rapid movement near the forward edge, contrasting with larger truck- or UAV-based Russian EW systems.
Public references treat 85Ya6 Leer-2 and Tigr-M MKTK REI PP as the same baseline EW vehicle, with an export designation and a reported alternate KAMAZ-4350 truck installation.
