El 9K111 Fagot, conocido por la OTAN como AT-4 Spigot, es un sistema soviético portátil de misil antitanque guiado por cable SACLOS construido en torno al lanzador de trípode 9P135 y la familia de misiles 9M111. Su lanzador reutilizable, la compatibilidad posterior del 9P135M con el 9M113 Konkurs y su alcance de 2 a 2,5 km mantuvieron su relevancia para usuarios heredados, con apariciones documentadas desde Ucrania hasta Gaza y Karabaj.

9M113 Konkurs, SACLOS wire-guided anti-tank guided missile, Infantry WeaponsInfantry Weapons9M113 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, BMP-series vehicle mounts, and the BRDM-2-based 9P148 carrier. Its SACLOS guidance, 135 mm missile body, and 4 km class engagement range kept the family useful after the Cold War, while the Konkurs-M modernization added tandem-HEAT and thermobaric options and remains in Russian export and Indian BDL production context.

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 5 km baseline range, with later missile variants reaching 6-7 km. In the 2014 Russia-Ukraine War, Russian 9P149 vehicles have been lost or captured, while Ukrainian units have shown Shturm-S training and Shturm-SM modernization work using domestic sights and RK-2P missiles.

Iran Press describes it as an Iranian reverse-engineered Konkurs-derived system used from ground and vehicle launchers, while Iran Watch links Tosan-1 production to the Aerospace Industries Organization. Conflict documentation ties Towsan-1 to Hezbollah's 2006 anti-armor inventory and Tosan missiles to Houthi-linked arms-flow and stockpile evidence in Yemen.

The original AT-7 Saxhorn used a lightweight launcher and 94 mm missile for short-range engagements, while the Metis-M and Metis-M1 upgrades moved to larger 130 mm missiles with tandem HEAT and thermobaric options. Its documented conflict use spans Russian and Ukrainian Metis-M fielding in Ukraine, Houthi use in Yemen, Syrian rebel use, and Hezbollah's anti-tank missile threat in the 2006 Lebanon War.
