Direct proof of use
Russian state reporting placed the 2S35 Koalitsiya-SV on the Ukraine front in December 2023. Rossiyskaya Gazeta, citing TASS and a source close to the Russian military department, reported that single examples were already being used in the operation and identified counter-battery fighting as their main task; the same article said the first vehicles had fired on the line of contact against Ukrainian artillery.
Reuters reporting carried by RFE/RL on December 27, 2023 added operator and delivery context. Rostec chief Sergei Chemezov said that the Koalitsiya-SV had completed testing, that mass production had started, and that the first pilot batch would be delivered by the end of 2023 for use against Ukrainian forces. RFE/RL also noted the earlier TASS report that single Koalitsiya-SV howitzers had already been deployed to the Ukrainian front line.

Battlefield role
The documented role is Russian long-range tube artillery, especially counter-battery fire. The December 2023 Russian report described limited use by single vehicles and framed the system as intended to affect counter-battery warfare rather than as a widely fielded artillery fleet. Army Recognition's specialist summary used the same role framing and described the deployment as limited in number while noting that official confirmation was still pending.
Rostec's technical and production statements explain why Russian sources tied the weapon to that role. The company described a 152 mm automated self-propelled artillery gun intended to engage artillery and mortar batteries, armored vehicles, personnel, air-defense assets, command posts, and fortifications; Chemezov specifically connected the Koalitsiya-SV's expected Ukraine deployment to a claimed range advantage over Western artillery.

Public record
The open record does not resemble the loss-and-capture documentation available for older Russian artillery systems in the same war. A Canadian Army Journal article noted that earlier Russian state-media claims of 2S35 use in Ukraine were unsubstantiated by credible sources at the time of writing and stated that the system had not yet entered combat. The later December 2023 reports therefore remain the central public basis for this conflict-use entry.
The public record does not include an independently verified loss list, captured-vehicle image, or location-specific battlefield report showing broad Koalitsiya-SV combat service. The system's documented conflict use is limited Russian fielding and reported counter-battery employment from late 2023 rather than large-scale deployment.
