Documented Use

Direct proof of use

The 2S12 Sani family is directly tied to the 2014 Russia-Ukraine War through OSCE Special Monitoring Mission reports from the Donbas phase and later full-scale-invasion evidence. On 4 March 2018, an OSCE mini-UAV observed four 2B11 Sani 120 mm mortars in firing positions about 2 km south-east of Vesela Hora, a non-government-controlled area north of Luhansk, with military trucks nearby that the mission assessed as carrying mortar ammunition crates.

The OSCE recorded another non-government-controlled sighting on 27 July 2018, when a mini-UAV spotted three probable 2B11/2S12 Sani mortars in firing positions on the southern edge of Donetskyi, west of Luhansk. The mission also documented a Ukrainian-side case on 12 August 2019, when a mini-UAV spotted a 2B11 Sani 120 mm mortar in government-controlled Hnutove.

Full-scale invasion evidence

After Russia's February 2022 full-scale invasion, the system appeared in capture, loss, and production-supply records. ArmyInform, an outlet of Ukraine's Ministry of Defense, reported on 4 October 2022 that Ukrainian troops captured a Russian 2B11 mortar from the modernized 2S12A Sani complex during a counteroffensive, along with mortar ammunition; the report noted that the related transport vehicle had not been confirmed captured in that case.

Oryx's visually confirmed Russian equipment-loss list separately records thirteen destroyed 2F510 transport vehicles for the 2S12 Sani mortar on the Ural-43206 chassis. In July 2024, Rostec announced new deliveries of upgraded 2S12A Sani systems and 2B11 mortars to Russia's Ministry of Defence, while Army Recognition described the delivery as going to Russian forces in Ukraine and placed the system in the Ukrainian-conflict context.

Role in the conflict

The documented cases place the 2S12/2B11 family in a conventional fire-support role. The pre-2022 OSCE reports treated 2B11 and probable 2B11/2S12 Sani mortars as heavy weapons observed in violation of withdrawal lines, including firing-position sightings in non-government-controlled Luhansk-region areas and a government-controlled Hnutove sighting.

The later evidence is strongest for Russian-side full-scale-invasion use and attrition. ArmyInform's October 2022 report describes a captured Russian 2S12A/2B11 mortar, Oryx records destroyed Russian 2F510 transport vehicles tied to the Sani system, and the 2024 Rostec delivery was reported in explicit Ukraine-war context by Army Recognition.

Related Weapons by Role

Drone-dropped fragmentation grenade, Improvised grenade-drop tactic using a commercial UAV, Aircraft & UAVsAircraft & UAVsDrone-dropped fragmentation grenadeImprovised grenade-drop tactic using a commercial UAVDrone-dropped fragmentation grenade is a field-adapted strike method that uses commercial quadcopters or similar small UAVs to release hand grenades or comparable fragmentation charges. Reporting from Ukraine and Gaza ties the method to improvised battlefield use by multiple sides, while a 2025 U.S. Army test with a Skydio X10D, an Audible dropper, and an M67 grenade shows the same concept moving into formal experimentation.
120-PM-38, 120 mm towed heavy mortar, ArtilleryArtillery120-PM-38120 mm towed heavy mortarThe 120-PM-38, also known as the M1938, is a Soviet 120 mm smoothbore heavy mortar designed under B. I. Shavyrin and built for infantry fire support. Its large bomb, two-wheel transport arrangement, and roughly 5.7 km range made it a durable regimental mortar design; OSCE monitoring documented PM-38 mortars in Donbas heavy-weapons holding and storage records during the 2014 Russia-Ukraine War, while Oryx listed M-1938 heavy mortars in Yemen's pre-war army inventory.
2S23 Nona-SVK, 120 mm wheeled self-propelled gun-mortar, ArtilleryArtillery2S23 Nona-SVK120 mm wheeled self-propelled gun-mortarThe 2S23 Nona-SVK is a Russian 120 mm self-propelled gun-mortar that adapts the Nona artillery system to a BTR-80 8x8 armored chassis. Its rifled 2A60 weapon can provide direct or indirect fire with mortar bombs, artillery projectiles, and selected guided ammunition, giving motorized units a compact battalion-level fire-support vehicle. The type was reported in Chechnya during Russian service testing and later appeared in 2014 Russia-Ukraine War battlefield reporting, including visually confirmed Russian losses and captured vehicles.
2S40 Floks, 120 mm wheeled self-propelled howitzer/mortar, ArtilleryArtillery2S40 Floks120 mm wheeled self-propelled howitzer/mortarThe 2S40 Floks is a Russian 120 mm wheeled self-propelled gun-mortar developed by Burevestnik under the Nabrosok artillery program and mounted on an armored Ural-4320 6x6 chassis. Open reporting ties it to Russian battlefield use in Ukraine from October 2023, where Ukrainian drone units documented strikes against newly fielded systems while Rostec and defense references describe the platform's combined mortar, howitzer-style indirect-fire, and direct-fire roles.
2S5 Giatsint-S, 152 mm tracked self-propelled gun, ArtilleryArtillery2S5 Giatsint-S152 mm tracked self-propelled gunThe 2S5 Giatsint-S is a Soviet 152 mm tracked self-propelled gun built for long-range corps- and army-level fire support. Its open rear-mounted 2A37 gun gives it greater reach than many older Soviet 152 mm systems, while its tracked chassis and stabilizing rear spade support shoot-and-move artillery work. Sources document 2S5 use or fielding context from Afghanistan and Grozny through the 2014 Russia-Ukraine War, where Russian units use the system and Ukrainian troops have restored at least one captured example for combat use.
2S35 Koalitsiya-SV, 152 mm tracked self-propelled howitzer, ArtilleryArtillery2S35 Koalitsiya-SV152 mm tracked self-propelled howitzerThe 2S35 Koalitsiya-SV is a Russian 152 mm tracked self-propelled howitzer developed as a highly automated successor to the 2S19 Msta-S, pairing a 2A88 gun, automated loading, digital fire-control features, and a T-90-derived chassis for long-range tube-artillery missions. Russian and specialist reporting placed small numbers near the 2014 Russia-Ukraine War front from late 2023, but the direct conflict record remains source-limited and centered on counter-battery claims rather than verified large-scale fielding.
2S43 Malva, 152 mm wheeled self-propelled howitzer, ArtilleryArtillery2S43 Malva152 mm wheeled self-propelled howitzerThe 2S43 Malva is a Russian 152 mm wheeled self-propelled howitzer that places a 2A64 gun on a BAZ 8x8 chassis for faster road moves and lower operating demands than tracked turreted artillery. Developed through the Nabrosok wheeled-artillery program, it entered Russian deliveries in 2023 and has since been documented with Russian forces in Ukraine, including reconnaissance sightings, Ukrainian strike reports, and visually confirmed losses.
M107 155 mm high-explosive projectile, 155 mm high-explosive projectile, ArtilleryArtilleryM107 155 mm high-explosive projectile155 mm high-explosive projectileThe M107 is a conventional 155 mm high-explosive projectile with a forged-steel body, TNT or Composition B fill, and deep- or normal-cavity variants for different fuze fits. U.S. Army ammunition records list it as an operations-and-sustainment item, Modern War Institute reporting places the M107 family in Ukraine's 155 mm ammunition mix, and U.S. emergency-sale notices document M107 deliveries to Israel during the 2023 Israel-Hamas War.
2S4 Tyulpan, 240 mm self-propelled heavy mortar, ArtilleryArtillery2S4 Tyulpan240 mm self-propelled heavy mortarThe 2S4 Tyulpan is a Soviet 240 mm self-propelled heavy mortar built around a large breech-loaded 2B8 mortar on a tracked chassis. Its unusually heavy bombs, guided and special-purpose ammunition options, and low rate of fire make it a siege and bunker-attack weapon rather than a conventional rapid-fire howitzer. Russian forces used it in Chechnya and have fielded or lost examples in Ukraine, where its size and firing signature make it a high-value counter-battery target.
DShKM heavy machine gun, 12.7 mm heavy machine gun, Infantry WeaponsInfantry WeaponsDShKM heavy machine gun12.7 mm heavy machine gunThe DShKM is the Soviet postwar Model 38/46 modernization of the DShK 12.7 mm heavy machine gun, retaining the DShK family's anti-aircraft, infantry-support, and vehicle-mount roles while replacing the earlier feed system. Sources document the DShK-1938/46 in Vietnam War anti-aircraft use, DShK-M capture and employment in the Soviet-Afghan War, DShK-M use by Ukrainian defenders, and DShK/DShKM variants in Islamic State's Iraq-and-Syria arsenal.
W85 heavy machine gun, 12.7 mm heavy machine gun, Infantry WeaponsInfantry WeaponsW85 heavy machine gun12.7 mm heavy machine gunThe W85 is a Chinese 12.7x108 mm heavy machine gun associated with Norinco export channels and the QJC-88 vehicle-mounted variant. It is lighter than many older DShK-pattern heavy machine guns and can be used from tripod, pintle, vehicle, or improvised pickup mounts. Conflict reporting documents W85-family guns with ISWAP-linked forces in Nigeria, Ukrainian mobile anti-drone teams, YPG/SDF improvised armor in Syria, Iraqi PMU militias, and Wagner-linked imagery from Mali, while sources caution that export paths and quantities are often unclear.
122 mm artillery round, 122 mm artillery ammunition, MunitionsMunitions122 mm artillery round122 mm artillery ammunitionThe 122 mm artillery round is a family-level label for Soviet-origin medium-caliber artillery ammunition used by D-30-type towed howitzers and 2S1 Gvozdika self-propelled howitzers. Manufacturer and military references describe separate-loading HE projectiles with full or reduced propelling charges, while U.S. security-assistance reporting documents 122 mm artillery rounds among ammunition committed to Ukraine and TWZ reporting describes a pair of 122 mm rounds as a standard AQ-400 Scythe payload.
