A directorate is roughly equivalent to a military wing. Each directorate is composed of a number of divisions and typically has at least three support divisions in addition to its research divisions. The Operations and Integration Division provides the directorate with well-conceived and executed business computing, human resource management, and business development services while the Financial Management Division manages the financial resources and the Procurement Division provides an in-house contracting capability. The support divisions at any given location frequently work together to minimize overhead at any given research site. Each division is then further broken down into branches, roughly equivalent to a military squadron.
