Direct proof of use
The 2S7 Pion is documented in the 2014 Russia-Ukraine War from the early Donbas period through the full-scale invasion. Armament Research Services reported in November 2014 that Ukraine was restoring multiple 2S7 Pion self-propelled artillery systems from storage, citing Ukrainian Ministry of Defence material and describing their intended use against separatist targets while remaining outside the Minsk buffer zone.
Later sources document operational use by both sides. Radio Free Europe/Radio Liberty published battlefield footage and reporting in October 2022 showing Ukrainian 2S7 Pion artillery pieces engaging Russian forces in Donetsk region, while a U.S. Army T2COM operational-environment article described Russia fielding 2S7 Pion heavy artillery in Ukraine for long-range fire support and counterbattery work.

Timeline
The sourced record begins in November 2014, when ARES documented Ukraine's return of stored 2S7 Pion guns to service during the Donbas war. During the full-scale invasion, Russian firing claims appeared in June 2022 in reporting based on Russian Ministry of Defense video, Ukrainian firing was documented in Donetsk region in October 2022, and satellite-imagery research later identified two Russian 2S7 systems and support vehicles near occupied Marianivka, Donetsk Oblast, on September 2, 2022.
Loss records provide another recurring indicator of fielding. Oryx lists visually documented Russian 203 mm 2S7(M) Pion/Malka losses and Ukrainian 203 mm 2S7 Pion losses during the full-scale invasion, separating those loss records from the more specific firing and deployment reports.

Operational narrative
Ukraine's documented use centers on heavy long-range artillery fires from a scarce Soviet-inherited system. The 2014 ARES article connected Ukraine's restoration effort to the weapon's ability to fire from outside the buffer zone, and the 2022 RFE/RL report described Ukrainian crews using the Pion's 37.5 km range against enemy artillery, command posts, ammunition depots, electronic-warfare stations, and other important targets in Donetsk region.
Ukrainian 43rd Artillery Brigade material reported by Defense Express shows the system remaining in service despite ammunition constraints. The outlet described 43rd Artillery Brigade use of 2S7 Pion guns and reported that Ukrainian crews were using U.S.-supplied 203 mm projectiles with local propellant-charge adaptations, while also identifying 43rd Brigade imagery of a Pion firing at Russian positions on the left bank of the Dnipro in Kherson region on November 11, 2022.
Russian use is documented through fielding analysis, official-video reporting, satellite imagery, and loss records. T2COM assessed that Russia was pulling 2S7 systems from storage, modernizing them, and placing them into ground-forces artillery units for the Ukraine conflict. Newsweek reported a Russian Ministry of Defense video showing 203 mm Pion guns firing in Ukraine, and Contested Ground identified two Russian 2S7 systems and support vehicles in satellite imagery southwest of occupied Marianivka in Donetsk Oblast on September 2, 2022.
The open-source record separates use from losses. Oryx's Russian list places 2S7(M) Pion/Malka systems among visually documented Russian equipment losses, and its Ukrainian list separately records Ukrainian 2S7 Pion losses. Those entries support battlefield fielding and attrition on both sides, while the firing reports and satellite-imagery report provide more specific evidence of operational use and deployment.
