Oryx documented BTR-60s fitted with AML-90 turrets under armored fighting vehicles in its September 2015 inventory of pre-war Yemeni Army fighting vehicles. The same article defines its scope as equipment in Yemeni Army service before the Houthi takeover of Yemen in 2014 and 2015, and says the inventory clarifies what military equipment was available to Yemeni parties on the battlefield.
The evidence supports conflict-context fielding and availability from former Yemeni Army stocks, but it does not identify a named later unit, a specific battlefield incident, or which Yemeni party operated each converted vehicle after the state inventory fragmented.

Timeline
The conversion was documented publicly on 20 September 2015, after the Houthi takeover of Sanaa and after the Saudi-led coalition intervention had widened the war. Oryx's article treats the listed vehicles as pre-war Yemeni Army equipment rather than new wartime acquisitions or production.
The cataloged timeline is therefore limited to documented inventory status and conflict availability. It does not establish a first combat firing date for the 90 mm gun or a loss, capture, or transfer event for a specific vehicle.

Narrative
The BTR-60 with AML-90 turret was an improvised Yemeni armored-vehicle conversion: a Soviet BTR-60PB wheeled armored personnel carrier hull fitted with the turret from a French Panhard AML-90 armored car. In the Yemen war context, that made the vehicle a direct-fire armored fighting vehicle rather than a standard APC.
Oryx's inventory places the conversion among other Yemeni armored fighting vehicles available during the civil war, alongside AML-90s and another AML-90 turret conversion on an M113 hull. The documented role is best described as improvised fire support from inherited Yemeni Army stocks, with post-takeover operator attribution remaining unresolved in the open sources used here.
The broader conflict context matters because Yemen's regular military inventory split across rival forces after the Houthi takeover and the 2015 coalition intervention. The source-backed claim for this vehicle stops at documented availability and fielding in that conflict environment; it should not be read as proof of a specific battle, front, or faction-level employment beyond the compact catalog side assignment.
