Direct proof of use
Houthi-aligned forces used technicals in Yemen as mobile fire-support vehicles. The War Zone documented Houthi Toyota Hilux-based technicals armed with 20 mm Vulcan cannon mounts, including imagery tied to operations against Saudi-led coalition or coalition-supported local forces in Lahij Governorate and a January 2017 video showing a Vulcan-armed technical in action in Taiz.
The same reporting said those Vulcan-armed trucks were part of a wider Houthi pattern of technical use, alongside more common vehicles carrying heavy machine guns, light automatic cannons, heavier guns, and rocket launchers. Reuters also documented Houthi fighters manning a machine gun mounted on a military truck during a July 2020 gathering near Sanaa.

Government-aligned front-line use
Technicals and similar armed pickup trucks were not limited to Houthi forces. During the 2021 Marib battle, Associated Press reporting from the Kassara front described government fighters and tribesmen defending the government stronghold against Houthi attacks, with most battalions relying on Kalashnikov rifles and machine guns mounted on pickup trucks.
Reuters imagery from March 2021 separately documented a Yemeni government fighter firing a vehicle-mounted weapon at a front-line position during fighting against Houthi fighters in Marib. Together, those sources support the role of truck-mounted weapons as front-line fire support for government-aligned forces around Marib.

Role in the conflict
In Yemen, the technical's conflict role was practical rather than standardized: a civilian or light truck chassis gave fighters mobility, while the mounted weapon turned the vehicle into a support-fire platform for local fronts, parades, and defensive positions. The Houthi Vulcan examples show the upper end of this improvisation, where captured or repurposed anti-aircraft cannon were mounted on unarmored trucks for ground fire support.
The evidence also separates possession from use. The War Zone attributed the source of Houthi M167 Vulcan systems to former Yemeni military stocks or coalition members but did not identify a single confirmed supply path. Small Arms Survey separately documented Houthi reuse of barrels from M167 Vulcan Air Defense Systems in locally produced 20 mm weapons, supporting the broader Houthi practice of repurposing heavy weapon components in Yemen.
