Direct proof of use
The M114A1 was publicly documented in Ukrainian service in April 2025, when UNITED24 and Militarnyi reported that Ukrainian forces had begun fielding the U.S.-origin 155 mm howitzer after footage appeared from a Ukrainian serviceman. Those reports described the weapon as being in active use, not merely in storage or pledged for transfer.
A later Frontliner field report placed an M114 with artillerymen of Ukraine's 152nd Jaeger Brigade in Donetsk region on October 15-16, 2025. The report described the crew at a position near the Pokrovsk front and documented the gun firing after a fire order, giving the strongest source-backed example of observed combat use.

Timeline
Transfer reporting preceded public combat-use imagery. In May 2022, Army Recognition reported that Portugal had approved sending five M114 155 mm towed howitzers to Ukraine, citing Portuguese newspaper reporting; Defense Express later described that Portuguese batch as earlier aid and reported a Greece-Czech channel for additional M114A1 howitzers.
Public battlefield confirmation came later. On April 23-24, 2025, UNITED24, Militarnyi, and Defense Express reported the first public appearance of M114A1 howitzers with Ukrainian forces. By October 2025, Frontliner documented a 152nd Jaeger Brigade crew operating an M114 in Donetsk region.

Narrative
The M114's role in Ukrainian service was conventional tube-artillery fire support. UNITED24 characterized the system as able to support indirect-fire missions despite its age, while Frontliner described a Ukrainian crew using the gun against Russian forces from a camouflaged frontline position.
The available sources separate transfer from observed use. Portugal was reported to have approved five M114 howitzers for Ukraine in 2022, and Greek stocks were reported through Czech-mediated assistance in 2024, but the public sources do not identify the exact donor origin of every gun later seen in Ukrainian service.
The system's battlefield value was bounded by its legacy design. Defense Express and UNITED24 both noted the 155 mm caliber and roughly 14.6 km maximum range; Frontliner's account showed a crew using it under persistent drone threat, with camouflage, short firing windows, and manual ammunition handling shaping its employment.
