Direct proof of use
The An-26's documented role in the Syrian Civil War was battlefield logistics. Oryx described Abu al-Duhur airbase as cut off from government-held territory and wrote that the Syrian Arab Air Force mainly used An-26s and Mi-8/17 helicopters to resupply the base with food, weapons, and other cargo before rebels captured the site in September 2015.
A January 2015 crash near Abu al-Duhur provides a dated incident record. UPI identified the aircraft as a Syrian military An-26 and reported that it was carrying soldiers, food, and ammunition to the besieged airbase; VOA and Reuters/DefenceWeb separately reported an army cargo aircraft carrying food and ammunition, with state media blaming weather and the Nusra Front claiming a shootdown.

Abu al-Duhur logistics role
Abu al-Duhur was a government-held airbase in Idlib province under a long siege by anti-government forces. Oryx's post-capture account placed An-26 flights inside the Syrian Arab Air Force resupply effort rather than in a bombing or close-air-support role, and linked the aircraft type to the garrison's ability to receive food, weapons, and other supplies after ground access was cut.
The January 2015 crash accounts describe the same logistics context. UPI reported that the aircraft was trying to land at Abu al-Duhur, while DefenceWeb's Reuters report and VOA both recorded competing explanations for the crash: Syrian state media attributed it to bad weather or heavy fog, and Nusra claimed it had shot the plane down. The direct use claim does not depend on resolving the crash cause; the supported point is that a Syrian army cargo aircraft, identified by UPI and DefenceWeb as an An-26, was being used for airlift to the besieged base.

Russian allied operations
The type also appears in Russia's Syria deployment, which supported the Syrian government from 2015. Al Jazeera reported that a Russian Antonov-26 transport aircraft crashed at Khmeimim airbase in Latakia province on March 6, 2018, killing 39 Russian military personnel, and said the Russian Defense Ministry reported no fire against the aircraft.
The Aviation Safety Network record identifies the aircraft as a Russian Air Force Antonov An-26, registration RF-92955/52, on a military flight from Kuweires Air Base to Latakia-Khmeimim Air Base. That record supports treating the 2018 loss as a military transport operation inside the Syrian theater, separate from the Syrian Arab Air Force's Abu al-Duhur resupply flights.

Conflict role
The supported conflict role is mobility and logistics. The sources document cargo, food, ammunition, soldiers, and military personnel transport, plus the loss of An-26 aircraft during approach or landing at Syrian airbases.
The available direct sources do not support describing the An-26 as a strike platform in this conflict-use record. The crash-cause claims around Abu al-Duhur remain attributed to the reporting parties because open reporting recorded conflicting government and Nusra accounts.
