Direct proof of use
The 2S5 Giatsint-S is documented in the 2014 Russia-Ukraine War on both sides of the conflict. A 2020 historical account by Mikhail Zhirokhov states that Ukrainian 2S5 batteries from the 26th Artillery Brigade were sent to the Donbas in summer 2014 and used during the early campaign, while an Armament Research Services annex published in November 2014 documented a Ukrainian army 2S5 captured by separatists near Amvrosievka.
For the full-scale invasion period, Oryx lists visually documented Russian 152 mm 2S5 Giatsint-S losses and Ukrainian 2S5 losses in its equipment-loss databases. Incident reporting also documents specific battlefield use: Gwara Media reported a Russian 2S5 position destroyed in the Kupiansk sector on November 27, 2023, and Defense Express reported on May 10, 2026 that Ukraine's 24th Brigade had restored a captured Russian 2S5 and fired it against Russian positions near Chasiv Yar.

Timeline
The earliest sourced 2014 milestones place Ukrainian Giatsint-S batteries in the Donbas by June 2014, followed by summer losses and captured materiel as the front expanded. Those 2014 accounts support Ukrainian use and separatist capture of at least one Ukrainian 2S5, but they do not establish a complete inventory or firing record for every gun.
After Russia's February 2022 full-scale invasion, visually documented loss lists and incident reporting show the system continuing to appear on the battlefield. Russian examples were recorded destroyed, damaged, or captured, while Ukrainian records include both legacy Ukrainian 2S5 losses and later use of a captured Russian gun restored by Ukrainian artillery crews.

Operational narrative
In Ukrainian service, the Giatsint-S filled a long-range 152 mm self-propelled artillery role inherited from the Soviet inventory. The Fraza account describes the system as scarce in Ukrainian service, with the available 2S5s concentrated in the 26th Artillery Brigade and committed to the Donbas in batteries during 2014. It also describes Ukrainian withdrawals from direct participation after the Minsk arrangements, which is consistent with the system's role as heavy artillery rather than a ubiquitous front-line vehicle.
Russian employment is visible in later open-source loss records and strike reporting rather than in a single official order of battle. Oryx records dozens of Russian 2S5 losses in the full-scale invasion, and the Gwara Kupiansk report identifies a Russian 2S5 position found by Ukrainian special forces and destroyed after HIMARS fire was adjusted onto it. These sources support fielding and battlefield exposure of Russian Giatsint-S guns without proving every listed loss was actively firing when struck.
Captured equipment forms a distinct part of the record. The 2014 ARES annex documents a Ukrainian 2S5 captured near Amvrosievka, while Defense Express reports the reverse pattern in 2026: Ukrainian artillery crews from the 24th Brigade restored a captured Russian Giatsint-S, nicknamed Kraken, and used it near Chasiv Yar. That report directly supports operational Ukrainian use of a captured Russian 2S5 rather than mere possession.
