The Steyr AUG is documented in the 2011 Syrian Civil War through open-source arms identification and reporting from opposition-held northern Syria. Profil reported in April 2015 that detailed photographs from Syria showed Liwa Tawhid rebel fighters in Aleppo with AUG assault rifles, and said the weapons' markings and older muzzle devices pointed to Austrian-produced export rifles rather than Australian or Austrian army service weapons.
Armament Research Services later documented one Steyr AUG offered for sale in north-western Syria in late April 2021. ARES wrote that AUG rifles had first been documented in Syria in early 2013 and that some had reportedly been supplied to opposition forces in northern Syria via Turkey, with Saudi-origin rifles a likely explanation for at least some examples.

Timeline
ARES places the earliest public documentation of Steyr AUG rifles in Syria in early 2013 and links some rifles to reported supply to northern opposition forces through Turkey. Profil's April 2015 reporting then identified Liwa Tawhid fighters in Aleppo with AUG rifles and described removed serial numbers and other physical features visible in the photographs.
By April 2021, ARES recorded an AUG offered for sale in north-western Syria, showing the rifle's continued presence in the opposition-held arms economy years after its first documented appearance.

Narrative
The documented Syria role for the Steyr AUG is as an opposition-held 5.56 mm self-loading rifle rather than a major system with a clear order of battle. The available sources support rebel possession and field presence in Aleppo and north-western Syria, while ARES and Profil both point to older export-pattern AUG rifles and likely Saudi-linked supply pathways.
The sources do not support a precise quantity, a full recipient chain, or a named engagement in which a specific AUG was fired. They do, however, directly place AUG rifles with Syrian rebel forces and in the north-western Syria arms market during the conflict, which supports the catalog's opposition-side conflict-use row.
