The Free Syrian Army is the main armed opposition and consists of several "brigades," "battalions," and "companies." The strength of each unit runs from as few as 15 fighters to the Khaled bin Walid Brigade in the area of Homs, which boasts 3,000 combatants in five battalions. The leadership of the FSA is in Turkey, and most units act with a high degree of autonomy. There is some coordination between adjacent units, but the FSA essentially operates as a cellular guerrilla network rather than a regular army.
The FSA lacks regular supplies of ammunition and appropriate weapons, notably antiarmor missiles.
