Direct proof of use
The documented conflict role for 81 mm mortar bombs in the 2014 Russia-Ukraine War is transfer and fielding for Ukrainian forces rather than a named public firing incident. U.S. Department of Defense assistance releases in 2023 and 2024 listed 81 mm mortar rounds among capabilities provided to Ukraine, and a U.S. reprogramming document separately identified replacement 81 mm high-explosive M889A2 mortar rounds as rounds that had been transferred to Ukraine.
Other donor records show the same caliber entering Ukrainian stocks from allied inventories. Norway announced in June 2024 that it had donated 81 mm mortar ammunition valued at about NOK 480 million and stated that the ammunition could be used by Ukraine in existing weapons. Canada's Ukraine support ledger records over 2,000 rounds of 81 mm mortar smoke donated from Canadian Armed Forces inventory and delivered in September 2024.

Timeline
In March 2023, the United States announced a drawdown package that included 81 mm and 60 mm mortar systems and mortar rounds. In April 2023, a separate U.S. package again listed 120 mm, 81 mm, and 60 mm mortar rounds along with 120 mm and 81 mm mortar systems.
By the FY 2023 reprogramming documentation for Ukraine replacement funding, the U.S. Army listed replacement procurement for 81 mm high-explosive M889A2 mortar rounds transferred to Ukraine. Later U.S. packages continued the supply line, including an 81 mm mortar-round listing in June 2024 and 60 mm and 81 mm mortar rounds in November 2024.
Norway and Canada added separate donor records in 2024. Norway announced 81 mm mortar ammunition for Ukraine in June 2024, while Canada records its 81 mm mortar smoke ammunition as delivered in September 2024.

Narrative
The 81 mm mortar-bomb record fits the wider ammunition-sustainment pattern of the war: Ukraine received mortar systems and compatible rounds from multiple partners as part of repeated artillery and infantry-fire-support packages. The available official sources identify transfer, donor country, caliber, and in some cases munition type, but they generally do not name front-line units, locations, or individual fire missions.
The clearest munition-type detail comes from U.S. and Canadian records. The U.S. reprogramming document names 81 mm high-explosive M889A2 mortar rounds that had been transferred to Ukraine, while Canada's public support ledger identifies 81 mm mortar smoke rounds from Canadian Armed Forces inventory. Norway's announcement emphasizes that its donated 81 mm mortar ammunition was intended for Ukraine's existing weapons, supporting fielding by Ukraine without specifying the exact round model.
