Direct proof of use
The 9K111 Fagot is documented on both sides of the 2014 Russia-Ukraine War, especially after Russia's full-scale invasion in February 2022. RUSI's early-war study of Ukrainian combat capabilities reported that the Ukrainian Armed Forces had more than a thousand Fagot and Metis anti-tank guided weapons, with several thousand missiles, in addition to Western-supplied and Ukrainian-produced anti-tank systems.
For Russian use, Army Recognition reported in July 2023 that Russia had formed specialized light anti-tank units using all-terrain vehicles equipped with AT-4 Spigot systems, the NATO designation for the 9K111 Fagot. The same report described Russian Ministry of Defense video footage showing the units' anti-armor role against Ukrainian vehicles.

Timeline
By the beginning of February 2022, Ukrainian forces retained a large stock of legacy Fagot and Metis anti-tank guided weapons alongside newer Stugna-P, Corsar, Barrier, Javelin, and NLAW systems. RUSI treated these weapons as part of the anti-tank capability available to Ukrainian ground forces in the opening phase of the full-scale invasion.
On 1 June 2022, Army Recognition listed 9K111 Fagot and 9K111M Fagot among anti-tank weapons used by Ukraine's army in the war. On 8 June 2023, according to Army Recognition's reporting on a Russian Ministry of Defense announcement, Russian forces publicized new high-mobility anti-tank units equipped with AT-4 Spigot systems. In August 2025, Defense Express reported that Ukraine's Kara-Dag 15th National Guard Brigade was training with the Fagot system for use against Russian armor.

Battlefield role
The Fagot's role in Ukraine is the same broad role for which it was designed: infantry anti-armor fire from a man-portable or light-vehicle-mounted launcher. It is not the longest-ranged or most modern anti-tank guided missile in Ukrainian service, but RUSI's inventory context shows that legacy Fagot-family missiles helped widen Ukraine's available anti-tank pool at the start of the full-scale invasion.
Ukrainian use is best supported at the force-capability level rather than through a single confirmed public strike in the sources used here. RUSI grouped Fagot with other short-ranged anti-tank guided weapons available to existing Ukrainian ground forces, while Army Recognition's June 2022 article listed 9K111 and 9K111M Fagot among the anti-tank weapons used by Ukraine's army.
Russian use is documented through fielding rather than a detailed independent battle-damage record. Army Recognition reported Russian AT-4 Spigot-equipped all-terrain anti-tank units in 2023, describing an ambush and rapid-repositioning role against Ukrainian armored vehicles.

Continued Ukrainian service
Defense Express reported in August 2025 that soldiers of Ukraine's Kara-Dag 15th National Guard Brigade were conducting live-fire training with the Fagot / AT-4 Spigot system. The article described the weapon as still useful for Ukrainian defense against Russian armored vehicles despite its Soviet-era design, with the brigade emphasizing training for first-shot accuracy under battlefield-like conditions.
