Mapping Syria’s Armed Opposition: Rebel Groups by Theater

Syria’s conflict is arguably one of the most complex and dynamic armed conflicts in the world, involving the national militaries of dozens of countries and thousands of domestic and foreign armed groups, all intertwined in a fractious myriad of coalitions and alliances. Perhaps the most complicated and difficult to understand are the armed groups participating in the rebellion against the government of Syrian President Bashar al-Assad, which transitioned from mass protests to armed rebellion in the second half of 2011. One of the most challenging and difficult problems for policymakers is mapping these groups - which adhere to a wide variety of ideologies — and understanding their relative strengths. But without doing so, devising policies that seek to empower and strengthen certain elements of the armed opposition is tremendously difficult. I seek here to provide a rough breakdown of Syria’s armed rebellion, not including the Islamic State group (ISIS, ISIL) or the YPG-led Syrian Democratic Forces (SDF), using publicly available estimates and basic arithmetic. For obvious reasons, this list is subject to change, and some estimates are certainly disputable. Some liberties were taken with regards to manpower estimates of smaller groups when numerical estimates have proven unavailable, roughly in line with media presence

Overall, there are likely somewhere between 120–125k fighters that belong to armed groups participating in Syria’s rebellion. Nationally, 54800 (44.7%) of these belong to armed groups vetted by the CIA and provided (at some point) with TOW Anti-Tank Guided Missiles. The CIA’s vetting program involves interviews with commanders and intercepts of their communications as a means of ascertaining their political acceptability, and is arguably the closest thing to a measure of political moderation. In addition, there are approximately 12000 fighters (9.8%) belonging to moderate Islamist groups that have not been vetted by the CIA. Nationalist Salafist groups — jihadist groups which don’t possess aspirations beyond Syria’s borders — comprise some 28250 fighters (23%), while transnationalist jihadist groups like Al Qaeda’s Syrian affiliate Jabhat al Nusra comprise roughly 18850 fighters (15.4%). A large number of small and generally highly-localized armed groups comprise the remainder, roughly 10000 fighters (~8%).

Below is a rough breakdown of these statistics, divided into three theaters: the north (Aleppo, Idlib, Hama and Latakia governates), the capital Damascus and its suburbs, and southern Syria (Deraa and Quneitra governates). A rebel-held pocket in northern Homs province may contain something like 5000 fighters split amongst FSA and Islamist groups, but information is difficult to gather, and I have declined to address the Rastan pocket accordingly.
