Clarification on the numbers: The network of circles in green represents the major military fronts the Supreme Military Council says operate under its command. The Council provided Al Jazeera a list of names of more than 900 military units totalling around 300,000 members. The military fronts provide a cumulative count of unit members in each location. These figures exclude members of independent groups, such as Jabhat al-Nusra and the Kurdish People's Protection Units. Both these groups refuse to reveal the number of fighters in their ranks and the figures in the diagram are merely estimates provided by activists and analysts.
