Oryx documented an M113 fitted with an AML-90 turret in its September 2015 handbook of pre-war Yemeni fighting vehicles. The article defines its scope as vehicles in Yemeni Army service before the 2014-2015 Houthi takeover and says the list was meant to clarify military equipment available to Yemeni battlefield parties.
A September 2022 thread by Yuri Lyamin on a Houthi parade in Hodeidah identified another improvised vehicle on an M113-variant chassis with a turret from the AML-90 or Ratel-90 family. Together, the sources support a conflict-use record for fielding and Houthi-aligned display of the conversion pattern, but they do not document a specific firing incident or named combat engagement.

Timeline
The relevant sequence begins with the Houthi takeover of Sanaa in September 2014 and the Saudi-led coalition intervention in March 2015, which made pre-war Yemeni Army stocks part of the conflict's battlefield-equipment record. Oryx published the M113-with-AML-90-turret listing on September 20, 2015, after the war had widened.
On September 2, 2022, Lyamin's Hodeidah parade thread described an M113-variant chassis carrying an AML-90 or Ratel-90-family turret among Houthi parade equipment. That later imagery provides the clearest public operator context for the conversion pattern.

Narrative
The vehicle was not a standard factory M113 variant. It combined an M113 tracked armored personnel carrier hull with a turret associated with the Panhard AML-90 armored car family, turning a troop-carrier chassis into an improvised direct-fire armored vehicle.
In the Yemen war context, the evidence points to legacy Yemeni Army stocks and local conversion practices rather than a newly supplied system. Oryx placed the vehicle alongside other armored fighting vehicles available from pre-war stocks, while the Hodeidah parade imagery tied a similar M113-variant conversion to Houthi-aligned forces years later.
The documented role is therefore limited to armored fire-support fielding and public display. The sources used here do not establish how many were converted, whether the pictured 2022 vehicle was the same hull listed by Oryx, or where the 90 mm weapon was fired in combat.
