Direct proof of use
The clearest public evidence for the Steyr AUG in the 2014 Yemen Civil War comes from Jamestown Foundation reporting on Yemen's wartime arms trade. In October 2016, Jamestown reported that Steyr AUG assault rifles, described as used by and provided by Saudi Arabia, had become abundant in Yemen's arms markets. In June 2017, the same publication again identified Steyr AUG rifles used by Saudi forces as part of the Yemen-war small-arms glut.
This record treats the AUG's Yemen role as Saudi-linked small-arms use and provision rather than a verified single battlefield firing incident. The sources directly connect the rifle to the Yemen conflict and to Saudi forces or Saudi provision, but they do not name a specific Saudi unit, Yemeni partner unit, front line, or engagement where an individual AUG was fired.

Timeline
Saudi Arabia's military intervention began on 26 March 2015, after Houthi-Saleh forces advanced toward Aden and Yemen's internationally recognized government fled. By August 2015, Washington Institute analysis described Saudi and UAE ground-force involvement around Aden and noted that Saudi Arabia was sending arms and vehicles over the border to bolster anti-Houthi forces in Marib and al-Jawf.
The AUG appears in public Yemen-specific reporting in October 2016, when Jamestown described a large supply of Steyr AUG rifles in Yemen and attributed them to Saudi use and provision. Jamestown's June 2017 arms-market article then placed the rifle inside a wider Saudi- and UAE-backed flow of weapons to anti-Houthi militias and government-aligned forces, many of which were leaking into local markets.

Narrative
Within the Yemen catalog, the Steyr AUG is best described as a coalition-linked infantry small arm. The available sources support Saudi use or provision and subsequent circulation in Yemen, especially through markets and poorly controlled transfer channels. They do not support assigning the rifle to Houthi forces as an original supply item, nor do they support a specific count or order of battle.
Jamestown's reporting frames the AUG as less sought after than anti-tank guided missiles and other advanced weapons, but still part of a conflict economy saturated with small arms. That distinction matters for role classification: the AUG entry is not evidence of a decisive system in a named battle, but it is direct evidence that this Austrian-origin rifle family was present in the Yemen war through Saudi-linked forces and supply.
