The mujahideen were fragmented politically into a handful of independent groups, and their military efforts remained uncoordinated throughout the war. The quality of their arms and combat organization gradually improved, however, owing to experience and to the large quantity of arms and other war matériel shipped to the rebels, via Pakistan, by the United States and other countries and by sympathetic Muslims from throughout the world. In addition, an indeterminate number of Muslim volunteers—popularly termed “Afghan-Arabs,” regardless of their ethnicity—traveled from all parts of the world to join the opposition.
