Direct proof of use
The TOS-2 Tosochka is tied to Russian use in the 2014 Russia-Ukraine War through Russian-state and defense reporting, followed by Ukrainian strike reporting against the system. Army Recognition reported that Russia's Ministry of Defense confirmed TOS-2 deployment in Ukraine on October 17, 2023, and said the vehicle was employed by Russian NRBC units against Ukrainian fortifications with extended-range projectiles.
Defense Express reported the same October 2023 public-visibility point from Ukrainian defense-media perspective: footage published by Russian state media RIA Novosti showed a TOS-2 claimed to fire on positions of the Armed Forces of Ukraine, while the article also noted that an earlier May 28, 2022 TASS notice had cited a military source without accompanying visual proof. TASS later reported on May 3, 2024 that Rostec chief Sergey Chemezov said Russian forces were intensively using TOS-2 heavy flamethrowers in the Russian-described special military operation.

Documented timeline
The earliest public claim in the sourced record is the May 28, 2022 TASS notice described by Defense Express and Army Recognition as a source-based report that TOS-2 had been deployed or used in Ukraine. Because those accounts emphasize the absence of visual confirmation at that point, the page treats the 2022 report as an early deployment claim rather than a confirmed filmed engagement.
The stronger public record begins in October 2023, when Army Recognition reported a Russian Ministry of Defense confirmation of deployment and Defense Express described the first public video of the system firing in Ukraine. In May 2024, TASS carried an on-record Rostec statement that TOS-2 systems were being actively used in the Ukraine operation. In February and March 2025, Ukrainian and Ukrainian defense-media reporting described the first documented loss and later FPV-drone strike reporting against a Russian TOS-2 in the Pokrovsk sector.

Battlefield role and evidence
The documented role was Russian thermobaric rocket fire support against Ukrainian positions and fortifications. Army Recognition described TOS-2 employment by Russian NRBC units against Ukrainian fortifications, while TASS presented the system as a successor to the TOS-1A with a wheeled Ural carrier, longer-range unguided rockets, automated aiming and fire control, an onboard crane, and electronic protection against precision weapons.
The conflict-use record should be read as evidence of Russian fielding and use, not as a complete order of battle. Army Recognition noted unverified Russian Telegram claims of action as early as June 2023 in the Zaporizhzhia area without photographic evidence; Defense Express similarly separated a 2022 source-based claim from the later October 2023 video. The later 2025 reporting documents Ukrainian strikes against at least one Russian TOS-2 near Pokrovsk, including a February wreckage report and a March Defense Express account attributing the destruction to Ukrainian FPV-drone pilots from the 68th Separate Jaeger Brigade.
