The MT-LB with ZU-23 anti-aircraft gun is documented in the 2014 Russia-Ukraine War through visually confirmed loss records for both Russian and Ukrainian forces. Oryx's Russian equipment-loss list records 53 Russian MT-LBs with ZU-23 AA guns, including destroyed, damaged, and captured examples, while its Ukrainian equipment-loss list records 14 Ukrainian MT-LBs with ZU-23 AA guns, also including destroyed, damaged, and captured examples.
The loss-list evidence supports fielding by both sides and shows the vehicle type appearing as battlefield materiel rather than only as a pre-war inventory item. Oryx's method is visual documentation of individual losses, so the strongest claim is that these conversions were present and lost in the war; it does not by itself identify every unit, firing mission, or tactical effect.

Dated appearances
The full-scale invasion beginning on February 24, 2022 created the period in which public loss records began separating MT-LB conversions by mounted weapon. Oryx's Russian list places the MT-LB with ZU-23 AA gun under Russian armored combat vehicle losses, and the Ukrainian list places the same conversion under Ukrainian armored combat vehicle losses.
By August 2023, Popular Mechanics described Russia and Ukraine as having fitted many MT-LBs with twin-barrel ZU-23 23 mm guns. The article summarized the Oryx-based photographic record at that point as at least 30 Russian 23 mm-armed MT-LBs destroyed or captured and eight Ukrainian examples lost, showing that the configuration had already become a visible wartime adaptation before later Oryx counts grew.

Role in the war
The conversion gave a lightly armored tracked tractor a high-volume 23 mm gun mount. Popular Mechanics described the Russian and Ukrainian ZU-23-armed MT-LBs as ersatz direct-fire combat vehicles, noting that the autocannon was more useful than machine guns at longer range and against covered personnel. The weapon's original anti-aircraft role also fits the cataloged air-defense classification, but the conflict-specific reporting most clearly supports a short-range air-defense and direct-fire support role rather than a single standardized doctrine.
The same evidence also shows the conversion's improvised character. The Oryx entries list them as MT-LBs with ZU-23 AA guns rather than as a single factory model, and the parent weapon record treats the type as a family of field and depot conversions. In Ukraine, both sides appear in the public record as operators and as loss sources, including examples captured by the opposing side.

Visual incident evidence
Conflict-specific video records add individual visual examples to the loss-list pattern, although they are less authoritative than the curated Oryx lists. Suchomimus published footage titles identifying an MT-LB with a mounted ZU-23-2 captured with a BMP-1 in eastern Ukraine in December 2022, a ZU-23-mounted MT-LB hit by an FPV drone near Zarichne in April 2023, and a drone-drop attack on a ZU-23-2-mounted MT-LB near Vodyane in April 2023.
Those videos are useful as open-source visual leads and as examples of the conversion appearing in capture and drone-strike contexts. The page's main use claim still rests on the two Oryx loss lists and the secondary synthesis, because those sources aggregate visually confirmed examples across the war.
