Federal Bureau of Investigation
The FBI is organized into branches and the Office of the Director. This office contains most administrative offices. An executive assistant director manages each branch. Each branch is then divided into offices and divisions. Each division is headed by an assistant director. The various divisions are further divided into sub-branches. Each sub-branch is led by deputy assistant directors. Within these sub-branches there are various sections headed by section chiefs. Section chiefs are ranked analogous to special agents in charge.
