Direct proof of use
The Sakr-6 appears in the 2014 Yemen Civil War record through Oryx's Houthi missile, rocket, and drone inventory. In the multiple-rocket-launcher section, Oryx lists a 122 mm Sakr-6 with Houthi-held systems and identifies it as inherited from pre-war Yemeni Army stocks.
That evidence supports Houthi-aligned possession or fielding of the launcher during the war. The cited public sources do not identify a specific Sakr-6 firing incident, target, battlefield location, or operator unit.

Timeline
Oryx's pre-war Yemeni fighting-vehicle inventory listed 122 mm Sakr-6 launchers among Yemeni Army multiple rocket launchers before the war expanded. The later Houthi inventory then listed the same launcher type among Houthi-held multiple rocket launchers in the continuing conflict.
The documented pathway is inherited stock rather than a new wartime transfer. The available open-source record is therefore stronger on custody and inventory provenance than on battlefield employment by incident.

Operational context
The Sakr-6 is a light six-tube 122 mm multiple rocket launcher associated with Egypt's Sakr/Grad-compatible rocket-artillery family. Forecast International describes the broader Sakr 122.4 mm family as including mobile launchers for Sakr rockets and Russian-pattern Grad rockets used by the BM-21 system, while the public Sakr-6 record in Yemen is limited to inventory imagery and identification.
In Yemen, the Sakr-6 should be read as part of the wider Houthi-aligned stock of inherited unguided rocket artillery rather than as a separately documented strike system. Its cataloged role is captured or inherited rocket-artillery materiel available to Houthi-aligned forces.
