The Alvis Saladin is documented in the 2014 Yemen Civil War through pre-war Yemeni Army inventory evidence. Oryx listed the Saladin under armored fighting vehicles in its September 2015 handbook of pre-war Yemeni fighting vehicles, a list it described as covering equipment in Yemeni Army service before the Houthi takeover in 2014 and 2015 and clarifying what military equipment was available to Yemeni battlefield parties.
That evidence supports Saladin fielding as legacy armored materiel in the conflict environment. It does not identify a dated Saladin sortie, a particular front, a vehicle loss, or a confirmed operator after the army's stocks fragmented.

Timeline
The relevant sequence begins with the Houthi takeover of Sanaa in 2014, which split state institutions and pushed the war toward a broader contest over Yemeni military stocks. CFR describes the war as beginning when Houthi forces took control of Sanaa in 2014, followed by the January 2015 seizure of the presidential palace and a Saudi-led intervention beginning in March 2015.
Oryx published its pre-war vehicle handbook on September 20, 2015, after the Saudi-led intervention had begun. Its Saladin listing therefore documents the type as part of the legacy Yemeni Army armored inventory available during the opening phase of the post-2014 conflict, rather than as a newly supplied coalition system.

Narrative
In Yemen, the Saladin's public evidence is narrower than its designed reconnaissance and direct-fire role. Army Guide describes the FV601(C) Saladin as a 6x6 armored car armed with a 76 mm L5A1 gun, coaxial and anti-aircraft machine guns, and smoke grenade dischargers, and lists Yemen among operators. Those characteristics explain why the vehicle belongs in the armored-fighting-vehicle inventory, but they do not by themselves prove use in any Yemeni battle.
The conflict-use claim therefore rests on Oryx's Yemen-specific inventory record: Saladins were present in the pre-war Yemeni Army armored vehicle pool that became available to battlefield parties after the 2014-2015 takeover. The page treats the vehicle as documented legacy materiel in the 2014 Yemen Civil War and avoids assigning a specific post-takeover user, location, or combat effect beyond what the sources directly support.
