9K111 Fagot
The 9K111 Fagot, known to NATO as the AT-4 Spigot, is a Soviet man-portable SACLOS wire-guided anti-tank missile system built around the 9P135 tripod launcher and 9M111 missile family. Its compact launcher, vehicle-mount compatibility, and 2 to 2.5 km range kept it relevant for legacy users, including Russian anti-tank teams documented in the Russia-Ukraine War.

9K114 ShturmRadio-command anti-tank guided missile systemThe 9K114 Shturm is a Soviet radio-command anti-tank guided missile system built around the 9M114 Kokon missile and known to NATO as AT-6 Spiral. Designed by KBM Kolomna for attack helicopters and the MT-LB-based 9P149 Shturm-S carrier, it combines SACLOS guidance, a fast missile, and a roughly 5 km baseline range. In the Russia-Ukraine War, Russian 9P149 vehicles have been captured or displayed as battlefield trophies, while Ukrainian units have shown Shturm-S use and modernization efforts to keep the system relevant for anti-armor missions.
9K115 MetisMan-portable anti-tank guided missile systemThe 9K115 Metis is a Soviet/Russian man-portable, wire-guided anti-tank guided missile family developed for company-level infantry anti-armor fire. The original AT-7 Saxhorn system emphasized a light launcher and short-range portability, while the later 9K115-2 Metis-M and Metis-M1 variants use larger 130 mm missiles, tandem HEAT or thermobaric warheads, and ranges up to 2 km. In the Russia-Ukraine War, Russian forces have been documented using the upgraded AT-13 Saxhorn-2 / Metis-M variant against Ukrainian armor.
9M113 KonkursSACLOS wire-guided anti-tank guided missileThe 9M113 Konkurs, NATO reporting name AT-5 Spandrel, is a Soviet wire-guided anti-tank guided missile family built for infantry launchers and vehicle mounts such as BMP-series vehicles and the BRDM-2-based 9P148. Its SACLOS guidance, 135 mm missile body, and 4 km class engagement range kept it useful after the Cold War, including documented employment in the Russia-Ukraine War by Ukrainian-aligned forces and Russian units.
9M133 KornetLaser beam-riding anti-tank guided missile systemThe 9M133 Kornet is a Russian heavy anti-tank guided missile system using laser beam-riding guidance and tandem HEAT or thermobaric warheads. Developed by KBP as a portable and vehicle-integrated ATGM family, it appears in the Russia-Ukraine War as a Russian-origin system documented with pro-Russian forces and also captured by Ukrainian troops.
BGM-71 TOWHeavy anti-tank guided missileThe BGM-71 TOW is a U.S. heavy anti-tank guided missile built around tube launch, optical tracking, and command guidance through a wire or later radio-frequency link. Developed by Hughes and now produced and upgraded by Raytheon, it can be fired from dismounted launchers, HMMWVs, Bradley and Stryker vehicles, light armored vehicles, and helicopters, giving infantry and vehicle crews a long-range precision anti-armor weapon. In the Russia-Ukraine War, U.S. security assistance packages sent TOW missiles to Ukraine as part of the anti-armor mix used to offset Russian armored forces.
FGM-148 JavelinAnti-tank guided missileA portable anti-armor missile known for top-attack profiles and fire-and-forget guidance. It became a symbol of early international military support to Ukraine.Sources
