Direct proof of use
Direct public evidence places the 2A65 Msta-B in Ukrainian frontline use during the full-scale phase of the war. Reuters identified a Ukrainian serviceman firing a 2A65 Msta-B toward Russian troops on a Zaporizhzhia-region frontline on January 5, 2023, and Voice of America published a February 6, 2023 image caption identifying members of Ukraine's 3rd Separate Assault Brigade firing a 152 mm 2A65 Msta-B near Bakhmut in Donetsk region.
Russian use is documented through visually confirmed loss tracking and later strike reporting. Oryx's Russian equipment-loss list for the full-scale invasion records 136 Russian 152 mm 2A65 Msta-B howitzers as destroyed, damaged, abandoned, captured, or damaged and captured. Ukrinform separately reported on August 29, 2025 that a Ukrainian FPV-drone pilot destroyed a Russian Msta-B in the Lyman sector and described the system as actively used by Russia in the war.

Battlefield role
The 2A65 Msta-B appears in the war as conventional towed 152 mm tube artillery. The weapon is a Soviet-designed split-trail howitzer, and U.S. Army ODIN describes the Msta-B, also designated 2A65, as a 152 mm towed howitzer developed toward the end of the Cold War.
On the Ukrainian side, the Reuters and Voice of America captions document the gun being fired from frontlines in southern and eastern Ukraine during the winter fighting of 2023. Those examples show the weapon in the same fire-support role as other Soviet-caliber artillery still present in Ukrainian service after the full-scale invasion.
On the Russian side, the evidence is strongest as a fielding and attrition record. Oryx lists Russian 2A65 Msta-B losses and captures during the invasion, while Ukrinform's Lyman-sector report describes a Russian Msta-B hidden in a shelter and destroyed by a Ukrainian FPV drone. Oryx's separate Ukrainian equipment-loss list also records Ukrainian 2A65 Msta-B losses, reinforcing that the howitzer remained present on both sides rather than appearing only as prewar inventory.
