Direct proof of use
The KS-19 is documented in Ukrainian service during the full-scale phase of the 2014 Russia-Ukraine War. Task & Purpose reported on April 2, 2023 that Ukrainian forces had put several KS-19 anti-aircraft guns into the field, with video showing guns aimed low and firing 100 mm rounds for artillery use against Russian ground forces.
Later reporting showed Ukrainian units turning the same legacy gun into mobile improvised artillery. Business Insider, summarizing a Daily Beast report, said the artillery battery of Ukraine's 241st Brigade mounted Soviet-era KS-19 guns on trucks and had received four KS-19s in March 2023. UNITED24 Media then reported from near Pokrovsk that the 111th Territorial Defense Brigade mounted a KS-19 on a used MAN truck and used the gun as a self-propelled artillery unit.
Defense Express independently described the MAN-mounted KS-19 as one of four guns received by the 111th Territorial Defense Brigade from old storage and said the unit used the improvised system on the Pokrovsk axis in eastern Ukraine to repel Russian infantry assaults.

Timeline
The public record begins in early 2023 with video-based reporting of Ukrainian KS-19 guns firing at low elevation as artillery. Business Insider's November 2023 report, citing the Daily Beast, placed four KS-19 guns with the 241st Brigade from March 2023 and described a three-month effort to rebuild them onto mobile platforms.
By July 2024, UNITED24 Media reported from the Pokrovsk direction with a Ukrainian crew operating a KS-19 that had been mounted on a MAN truck. In October 2024, Defense Express gave the same 111th Territorial Defense Brigade context and described the MAN-mounted KS-19 as part of the unit's improvised artillery work on the Pokrovsk axis.

Battlefield role
In Ukrainian service, the KS-19 appears as expedient fire support rather than as a modern anti-aircraft weapon. Task & Purpose described Ukrainian crews firing the 100 mm guns at low elevation and loading UOF-412 rounds, while UNITED24 Media and Defense Express described use against ground targets, enemy positions, light vehicles, and infantry assaults.
The sources also distinguish storage, recovery, and use. UNITED24 Media reported that Ukraine had just under 200 KS-19s in warehouses at Balakliia, that Russian forces occupied the town in 2022, and that Ukrainian soldiers found most of the guns after the Kharkiv region was liberated. That storage and recovery context explains the available legacy inventory, but the direct conflict-use claims come from the reported firing, brigade use, and truck-mounted artillery accounts.
The truck-mounted conversions addressed the limits of a heavy towed gun close to the front. UNITED24 Media reported that the 111th Territorial Defense Brigade added mobility by mounting the gun on a MAN truck, while Defense Express emphasized mobility and camouflage against drones and counter-battery fire. The cited material supports a role as improvised towed and self-propelled artillery for Ukrainian ground-fire missions, not a standardized production self-propelled gun.
