Direct proof of use
The Leopard 2 is documented in the 2011 Syrian Civil War through Turkish Leopard 2A4 use during Operation Euphrates Shield. A SETA operational study describes a December 21, 2016 attempt to take the hospital region on Akil Hill west of al-Bab by a company of about 150 Turkish troops with Leopard 2A4 tanks and ZMA-15 vehicles, under heavy Islamic State fire.
Bellingcat later geolocated multiple damaged or destroyed Leopard 2A4 tanks west of al-Bab by cross-referencing Islamic State imagery with DigitalGlobe satellite imagery from February 7, 2017. Its conclusion identified at least eight Leopard 2A4 tanks damaged or destroyed during the western al-Bab offensive by Euphrates Shield forces.

Timeline
Turkey launched Operation Euphrates Shield on August 24, 2016, sending ground forces, tanks, aircraft, and Turkish-backed Syrian opposition fighters into northern Syria against Islamic State and Kurdish militia objectives. Leopard 2A4 documentation becomes specific in the al-Bab phase, which SETA dates from December 21, 2016 to March 30, 2017.
On December 21, 2016, SETA says Turkish troops with Leopard 2A4 tanks and ZMA-15 vehicles took the Akil Hill hospital region at night but were exposed to mortar, ZU-23, and anti-tank fire, followed by a bomb-laden armored BMP-1 attack and the loss of 15 armored vehicles in the first al-Bab attempt. By February 2017, Bellingcat had geolocated Leopard 2A4 wrecks and damaged tanks from the same western al-Bab battle area.

Narrative
The Syrian Civil War Leopard 2 record centers on Turkey rather than Syrian government, opposition, or Islamic State ownership of the tank. The documented operator was the Turkish Armed Forces during Operation Euphrates Shield, a Turkish cross-border campaign fought with Turkish-backed Syrian opposition forces against Islamic State positions in northern Syria.
At al-Bab, the Leopard 2A4 served as part of Turkey's armored assault package. SETA places the tanks with Turkish troops in a night operation against the hospital region west of the city and describes the force becoming vulnerable to heavy fires and a vehicle-borne explosive attack after taking the area. Jamestown's campaign summary separately identifies the Aqil Mountain and al-Bab hospital area as a key frontline in the offensive.
The clearest loss evidence comes from open-source imagery rather than a full official Turkish inventory. Bellingcat matched Islamic State drone footage, still images, and satellite imagery to several Leopard 2A4 locations west of al-Bab, including destroyed tanks near al-Aqil hill and damaged tanks near the hospital area. Its analysis did not attribute every tank loss to a single cause; for some vehicles it noted possible anti-tank guided missile hits, suicide vehicle-borne improvised explosive devices, or later Turkish airstrikes against abandoned equipment.
