Note: The pro-Syrian government National Defence Forces have an active branch in al-Hasakah Governorate, but have refused to fight alongside the SDF against Turkish-led forces. This is motivated by animosity of local NDF troops toward the SDF, as well as internal leadership disputes that have paralyzed al-Hasakah's NDF. In addition, the General Intelligence Branch 330 is known to be active in northern Syria.[44]
