The M167 Vulcan is a U.S.-origin towed short-range air-defense gun built around the 20 mm M168 six-barrel rotary cannon. In Yemen, Houthi forces have been documented using captured Vulcan guns on improvised vehicle mounts, giving the system a mobile direct-fire role alongside its original close-in air-defense function.
Houthi forces used captured M167 Vulcan guns during the Yemen Civil War, including examples mounted on Toyota Hilux technicals, an M54-series truck, and a BTR-152; reporting assessed their main observed use as ground fire against coalition-backed forces while retaining limited short-range air-defense utility.
ZPU-1 anti-aircraft gunSingle-barrel 14.5 mm towed anti-aircraft gunThe ZPU-1 is the single-barrel member of the Soviet ZPU family, mounting a 14.5 mm KPV heavy machine gun on a light two-wheel carriage. In Yemen Civil War sourcing it appears in the Yemeni Army inventory and in technical-mounted configurations, making it a low-level air-defense and direct-fire weapon rather than a modern radar-guided system.
2K12 Kub / Kvadrat / SA-6 GainfulTracked medium-range surface-to-air missile systemThe 2K12 Kub, exported as Kvadrat and known to NATO as SA-6 Gainful, is a Soviet tracked medium-range surface-to-air missile system built around 3M9 missiles, 2P25 launch vehicles, and the 1S91 Straight Flush radar. In recent conflict archives it appears as a legacy medium-range air-defense system, including Syrian use during the 2018 missile strikes, Armenian use in Nagorno-Karabakh, and a Houthi SA-6/Kub-family engagement that downed a U.S. MQ-9 over Yemen in 2019.
9K31 Strela-1Vehicle-mounted short-range surface-to-air missile systemThe 9K31 Strela-1, NATO reporting name SA-9 Gaskin, is a Soviet BRDM-2-based short-range surface-to-air missile system armed with 9M31 infrared-guided missiles. In the Yemen Civil War it is documented in Houthi-aligned air-defense holdings as equipment inherited from pre-war Yemeni Army stocks, a conservative indication of point air-defense capacity rather than a sourced claim for a specific engagement.
