66th Division (Syria)


The 66th Division of the Syrian Army, established between March and April 2025, under the Syrian Transitional Government, is responsible for the eastern border region of Syria, which includes Al-Bukamal, and Deir ez-Zor, covering a sector of more than 250 kilometers. Most of the division's personnel are former members of Ahrar al-Sharqiya and the Zubair bin al-Awam Brigade of Hay'at Tahrir al-Sham, a Sunni Islamist paramilitary group.
The division is tasked with securing and monitoring Syria’s eastern border areas, maintaining control over key crossings and transport routes.

History

The deployment of the division to the eastern Syria area began in mid-April, but it appeared to be incomplete due to an ongoing shortage of personnel.
The division engaged in sporadic fighting with SDF forces along the Euphrates contact line in 2025.

The division is commanded by Ahmad al-Muhmad, originally from Tabqa in the Raqqa region.
