Direct proof of use
Russian Ministry of Defence-linked reporting in January 2024 directly placed Sobolyatnik crews with Russia's Western Group of Forces on the Kupyansk axis. RIA Novosti reported that UAV operators and Sobolyatnik radar crews identified Ukrainian positions and passed target coordinates to artillery units, and Army Recognition separately described Russian Armed Forces deployment of 1L277 Sobolyatnik portable ground-reconnaissance radar stations in Ukraine.
Ukrainian and open-source loss documentation also places the radar in the conflict. Ukraine's Ministry of Internal Affairs reported on September 4, 2023, that aerial-reconnaissance groups of the National Guard's 27th Pechersk Brigade destroyed one 1L227 Sobolyatnik radar during operations on the Lyman, Donetsk, Kherson, and Melitopol axes. UNIAN reported a separate Tavriia-direction statement by Brigadier General Oleksandr Tarnavskyi that Ukrainian forces destroyed a small portable Sobolyatnik radar, while Oryx lists one Russian Sobolyatnik 1L277 portable ground reconnaissance radar as photo-documented destroyed.

Timeline
The earliest dated public loss claim used for this record is the UNIAN report from July 30, 2023, which attributed a Tavriia-direction Sobolyatnik destruction claim to Tarnavskyi. Ukraine's MVS then published a September 4, 2023 National Guard report covering the previous week, naming one 1L227 Sobolyatnik among equipment destroyed by aerial-reconnaissance groups.
On January 10, 2024, RIA Novosti published the most explicit Russian operational-use account, saying Sobolyatnik crews and UAV operators on the Kupyansk axis detected Ukrainian positions and sent coordinates for artillery attack. Army Recognition's same-day conflict report summarized the deployment as Russian use of 1L277 Sobolyatnik ground reconnaissance radars in Ukraine, and Armeyskiy Standart's January 23, 2024 article described front-line use of the radar in Russia's Ukraine operation.

Battlefield role
The documented role was surveillance and targeting support rather than direct fire. Russian reporting described Sobolyatnik crews working with UAV operators, detecting Ukrainian positions, relaying coordinates to artillery units, tracking projectile trajectories, and supporting fire correction or counter-battery work. Armeyskiy Standart described preferred targets during the operation as reserves, movement routes, armored vehicles, rocket artillery, troop concentrations, and UAV operators.
The published evidence does not show Ukrainian operation of the 1L277; the source-backed side for this usage page is Russia. Ukrainian sources and Oryx primarily support destruction or loss claims, while Russian and defense-industry reporting support fielding, front-line employment, and the radar's reconnaissance and artillery-support functions in the war.
