Direct proof of use
Armament Research Services documented the AM-50 Sayyad in the 2014 Yemen Civil War on December 1, 2015, after assessing social-media images that appeared to show a Houthi fighter armed with the Iranian AM50, also identified as the Sayyad-2. Small Arms Defense Journal later republished the ARES report with the same Yemen-specific finding.
The evidence supports Houthi-aligned fielding of the rifle in Yemen, but it does not establish a precise engagement, unit inventory, casualty effect, or verified number of rifles. The source identifies the weapon in the hands of a fighter rather than documenting a separate firing incident.

Timeline
The dated public milestone for the Yemen record is the ARES publication on December 1, 2015, during the first high-intensity year after the Saudi-led coalition intervention. The source does not date the underlying images beyond describing them as recent at the time of publication.
Small Arms Defense Journal republished the ARES article on August 9, 2023, preserving the Yemen identification and technical summary. That later publication is useful corroboration of the ARES finding, but it does not add a new battlefield date.

Narrative
In Yemen, the AM-50 Sayyad appears as a Houthi-aligned heavy sniper and anti-materiel rifle. ARES identifies the weapon as an Iranian state-produced, single-shot, bolt-action rifle chambered for 12.7 x 99 mm, and Conflict Armament Research separately describes the AM-50 as an Iranian anti-materiel rifle derived from the Steyr HS .50 pattern.
ARES treated the supply route as an assessment rather than a confirmed delivery record. The report said direct material support from Iran was the most likely avenue for the AM-50's presence in Yemen, while also noting that movement of Shi'a fighters from other conflict zones could account for the weapon. This page therefore records Houthi-aligned use and Iranian weapon origin, not a verified transfer chain for the specific rifle shown.
