Direct proof of use
The 152 mm ML-20 appears in the 2014 Russia-Ukraine War as a Russian legacy towed artillery piece documented during the full-scale phase of the conflict. Defense Express reported on October 9, 2025 that Ukrainian gunners from the 55th Separate Artillery Brigade destroyed a Russian ML-20 during counter-battery operations in Donetsk region.
The report identified the weapon as the Soviet 152 mm gun-howitzer model 1937 and described its battlefield appearance as a sign that Russian forces were drawing on very old artillery stocks to maintain firepower.

Narrative
The documented role was conventional tube-artillery fire support rather than a new production or transfer program. The ML-20 was a pre-Second World War Soviet heavy gun-howitzer, and its appearance in Russian service in 2025 fits the broader pattern of reserve and legacy artillery being pulled into the war.
The Donetsk-region incident is also a counter-battery record. Defense Express described Ukrainian units combining reconnaissance and fire correction to locate and destroy Russian artillery, making the ML-20's loss evidence of both Russian use and Ukrainian efforts to reduce Russian artillery firepower.
