Military ranks are a system of hierarchical relationships within armed forces, police, intelligence agencies and other institutions organized along military lines. Responsibility for personnel, equipment and missions grow with each advancement. The military rank system defines dominance, authority and responsibility within a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command is an important component for organized collective action.
Commander is a common naval officer rank as well as a job title in many armies. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries, this naval rank is termed as a frigate captain.
Joint Base Anacostia–Bolling (JBAB) is a 905-acre (366 ha) military installation, located in Southwest Washington, D.C., established on 1 October 2010 in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of Naval Support Facility Anacostia and Bolling Air Force Base (BAFB), which were adjoining but separate military installations into a single joint base, one of twelve formed in the country as a result of the law. The base hosts the Defense Intelligence Agency Headquarters amongst its other responsibilities. The only aeronautical facility at the base is a 100-by-100-foot helipad.
An executive officer is a person who is principally responsible for leading all or part of an organization, although the exact nature of the role varies depending on the organization. In many militaries and police forces, an executive officer, or "XO", is the second-in-command, reporting to the commanding officer. The XO is typically responsible for the management of day-to-day activities, freeing the commander to concentrate on strategy and planning the unit's next move.

In this respect, commanding officers have significant responsibilities, duties, and powers.
A group is a military unit or a military formation that is most often associated with military aviation.
