The Defense Information Systems Agency (DISA), known as the Defense Communications Agency (DCA) until 1991, is a United States Department of Defense (DoD) combat support agency composed of military, federal civilians, and contractors. DISA provides information technology (IT) and communications support to the President, Vice President, Secretary of Defense, the military services, the combatant commands, and any individual or system contributing to the defense of the United States.
The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, which advises the president of the United States, the secretary of defense, the Homeland Security Council and the National Security Council on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of a chairman (CJCS), a vice chairman (VJCS), the chiefs of the Army, Marine Corps, Navy, Air Force, Space Force, and the chief of the National Guard Bureau. Each of the individual service chiefs, outside their JCS obligations, works directly under the secretaries of their respective military departments, e.g. the secretary of the Army, the secretary of the Navy, and the secretary of the Air Force.
The United States Fleet Forces Command (USFFC) is a service component command of the United States Navy that provides naval forces to a wide variety of U.S. forces. The naval resources may be allocated to Combatant Commanders such as United States Northern Command (USNORTHCOM) under the authority of the Secretary of Defense. Originally formed as United States Atlantic Fleet (USLANTFLT) in 1906, it has been an integral part of the defense of the United States of America since the early 20th century. In 2002, the Fleet comprised over 118,000 Navy and Marine Corps personnel serving on 186 ships and in 1,300 aircraft, with an area of responsibility ranging over most of the Atlantic Ocean from the North Pole to the South Pole, the Caribbean Sea, Gulf of Mexico, and the waters of the Pacific Ocean along the coasts of Central and South America.
The Goldwater–Nichols Department of Defense Reorganization Act of October 4, 1986 made the most sweeping changes to the United States Department of Defense since the department was established in the National Security Act of 1947 by reworking the command structure of the U.S. military. It increased the powers of the chairman of the Joint Chiefs of Staff and implemented some of the suggestions from the Packard Commission, commissioned by President Reagan in 1985. Among other changes, Goldwater–Nichols streamlined the military chain of command, which now runs from the president through the secretary of defense directly to combatant commanders, bypassing the service chiefs. The service chiefs were assigned to an advisory role to the president and the secretary of defense, and given the responsibility for training and equipping personnel for the unified combatant commands.
United States Space Command is a unified combatant command of the United States Department of Defense, responsible for military operations in outer space, specifically all operations 100 kilometers and greater above mean sea level. U.S. Space Command is responsible for the operational employment of space forces that are provided by the uniformed services of the Department of Defense.
The United States Strategic Command (USSTRATCOM) is one of the eleven unified combatant commands in the United States Department of Defense. Headquartered at Offutt Air Force Base, Nebraska, USSTRATCOM is responsible for strategic nuclear deterrence, global strike, and operating the Defense Department's Global Information Grid. It also provides a host of capabilities to support the other combatant commands, including integrated missile defense; and global command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR). This command exists to give "national leadership a unified resource for greater understanding of specific threats around the world and the means to respond to those threats rapidly".
The United States European Command (EUCOM) is one of the eleven unified combatant commands of the United States military, headquartered in Stuttgart, Germany. Its area of focus covers 21,000,000 square miles (54,000,000 km2) and 51 countries and territories, including Europe, The Caucasus, Russia and Greenland. The Commander of the United States EUCOM simultaneously serves as the Supreme Allied Commander, Europe (SACEUR) within NATO, a military alliance. During the Gulf War and Operation Northern Watch, EUCOM controlled the forces flying from Incirlik Air Base.
Network-centric warfare, also called network-centric operations or net-centric warfare, is a military doctrine or theory of war that aims to translate an information advantage, enabled partly by information technology, into a competitive advantage through the computer networking of dispersed forces. It was pioneered by the United States Department of Defense in the 1990s.
A unified combatant command, also referred to as a combatant command (CCMD), is a joint military command of the United States Department of Defense that is composed of units from two or more service branches of the United States Armed Forces, and conducts broad and continuing missions. There are currently 11 unified combatant commands, and each is established as the highest echelon of military commands, in order to provide effective command and control of all U.S. military forces, regardless of branch of service, during peace or during war time. Unified combatant commands are organized either on a geographical basis or on a functional basis, e.g., special operations, force projection, transport, and cybersecurity. Currently, seven combatant commands are designated as geographical, and four are designated as functional. Unified combatant commands are "joint" commands and have specific badges denoting their affiliation.
NetOps is defined as the operational framework consisting of three essential tasks, Situational Awareness (SA), and Command & Control (C2) that the Commander (CDR) of US Strategic Command (USSTRATCOM), in coordination with DoD and Global NetOps Community, employs to operate, manage and defend the Global Information Grid (GIG) to ensure information superiority for the United States.
Joint Task Force-Global Network Operations (JTF-GNO) was a subordinate command of United States Strategic Command whose mission was to: direct the operation and defense of the Global Information Grid (GIG) across strategic, operational, and tactical boundaries in support of the US Department of Defense's full spectrum of war fighting, intelligence, and business operations.
Allied Command Transformation (ACT) is a military command of the North Atlantic Treaty Organization (NATO), formed in 2003 after restructuring.
The Command and Control Research Program (CCRP) was an active DoD Research Program from 1994 to 2015. It was housed within the Office of the Assistant Secretary of Defense (NII) and it focused upon (1) improving both the state of the art and the state of the practice of command and control (C2) and (2) enhancing DoD's understanding of the national security implications of the Information Age. It provides "Out of the Box" thinking and explores ways to help DoD take full advantage of Information Age opportunities. The CCRP served as a bridge between the operational and technical communities and enhanced the body of knowledge and research infrastructure needed for future progress.
Area of responsibility (AOR) is a pre-defined geographic region assigned to Combatant commanders of the Unified Command Plan (UCP), that are used to define an area with specific geographic boundaries where they have the authority to plan and conduct operations; for which a force, or component commander bears a certain responsibility. The term may also be used in other countries worldwide but it originated within the United States Armed Forces. This system is designed to allow a single commander to exercise command and control of all military forces in the AOR, regardless of their branch of service.
The United States Atlantic Command was a Unified Combatant Command of the United States Department of Defense. In 1999, U.S. Atlantic Command was renamed and given a new mission as United States Joint Forces Command.
Within the United States Department of Defense, the Joint Capability Areas (JCA) are a standardized set of United States military definitions that cover the complete range of military activities. The system was initially established in May 2005 by the United States Department of Defense Joint Staff with input from each of the services, designed to begin "a new framework that paves the way for side-by-side comparisons of service contributions to joint warfighting and a tool that will assist decision-makers in deciding whether to move resources between service budgets."
The United States Department of Defense (DoD) has a complex organizational structure. It includes the Army, Navy, the Marine Corps, Air Force, Space Force, the Unified combatant commands, U.S. elements of multinational commands, as well as non-combat agencies such as the Defense Intelligence Agency and the National Security Agency. The DoD's annual budget was roughly US$496.1 billion in 2015. This figure is the base amount and does not include the $64.3 billion spent on "War/Non-War Supplementals". Including those items brings the total to $560.6 billion for 2015.
JEFX, or Joint Expeditionary Force Experiment, was the periodic US Air Force-led operational experiment created to evaluate new technologies and war fighting concepts in a simulated wartime battle environment. It was an outgrowth of the C4I Initiative mandated by the Goldwater-Nichols Act of 1986. It was monitored by the Air Force senior leadership and each event culminated with a report for the Chief of Staff of the Air Force.
A battle lab or battle laboratory is an organization dedicated to studying changes in the military.
The Joint Deployable Analysis Team (JDAT) is part of the J6 Directorate of the Joint Chiefs of Staff.
