The document discusses how Al-Qaeda has changed from a hierarchical organization directed from a central base, to a more decentralized structure. It has devolved into several "tracks" including main Al-Qaeda forces, designated organizations in different regions, financed groups, self-radicalized individuals and cells, and a hybrid mixture. This makes the group's order of battle, or organizational structure, more difficult to determine than when it was a centralized organization led by Bin Laden and Zawahiri.
