As directed by the President to identify opportunities to cut costs and rebalance priorities, Defense Secretary Robert Gates recommended that USJFCOM be disestablished and its essential functions reassigned to other unified combatant commands. Formal disestablishment occurred on 4 August 2011.
The Joint Functional Component Command for Intelligence, Surveillance and Reconnaissance was a subordinate command of the United States Strategic Command, one of the nine Unified Combatant Commands under the United States Department of Defense (DOD) and co-located with the Defense Intelligence Agency (DIA). It served as the center for planning, execution, and assessment of the United States military's global Intelligence, Surveillance, and Reconnaissance operations from 2005-2016; a key enabler in achieving global situational awareness. In 2016 JFCC-ISR was realigned to the Joint Staff.

Joint Force Headquarters National Capital Region (JFHQ-NCR) is directly responsible for the homeland security and defense of the Washington D.C. area as well as surrounding counties in Virginia and Maryland. Primarily made up of joint military units within the National Capital Region, the JFHQ-NCR assists federal and local civilian agencies and disaster response teams in the event that the capital area's security is or possibly could be breached by acts of terrorism. Officially activated on September 22, 2004, JFHQ-NCR is part of United States Northern Command.
The United States Department of Defense is an executive branch department of the federal government of the United States charged with coordinating and supervising all agencies and functions of the U.S. government directly related to national security and the United States Armed Forces.

Headquartered at the Pentagon in Arlington County, Virginia, just outside Washington, D.C., the Department of Defense's stated mission is to provide "the military forces needed to deter war and ensure our nation's security".
Purdue University's Synthetic Environment for Analysis and Simulations, or SEAS, is currently being used by Homeland Security and the US Defense Department to simulate crises on the US mainland. SEAS "enables researchers and organizations to try out their models or techniques in a publicly known, realistically detailed environment." It "is now capable of running real-time simulations for up to 62 nations, including Iraq, Afghanistan, and China. The simulations gobble up breaking news, census data, economic indicators, and climactic events in the real world, along with proprietary information such as military intelligence. [...] The Iraq and Afghanistan computer models are the most highly developed and complex of the 62 available to JFCOM-J9. Each has about five million individual nodes representing things such as hospitals, mosques, pipelines, and people."
Virginia Modeling, Analysis and Simulation Center (VMASC) is a multi-disciplinary research center of Old Dominion University. VMASC supports the University’s Modeling & Simulation (M&S) degree programs, offering M&S Bachelors, Masters and Ph.D. degrees to students across the Colleges of Engineering and Technology, Sciences, Education, and Business. Working with more than one hundred industry, government, and academic members, VMASC furthers the development and applications of modeling, simulation and visualization as enterprise decision-making tools to promote economic, business, and academic development.
The counter-terrorism page primarily deals with special police or military organizations that carry out arrest or direct combat with terrorists. This page deals with the other aspects of counter-terrorism:
The Joint Personnel Recovery Agency (JPRA) is a Chairman's Controlled Activity and is designated as DoD's office of primary responsibility for DoD-wide personnel recovery (PR) matters, less policy. JPRA is headquartered in Fort Belvoir, Virginia with schools located in Fredericksburg, VA and Spokane, WA. JPRA currently provides for commanders, forces, and individuals on joint PR activities through development and conduct of education and training courses, and specialized individual training. The agency assesses, advises, and evaluates PR curriculum and establishes Joint PR standards in collaboration with the DoD Components for formal Joint PR training, including Code of Conduct and SERE. JPRA also provides DoD Components with analytical support, technology research and integration, maintenance of databases and archives, and development of lessons learned. JPRA encourages partnerships by assisting with non-DoD agencies, multinational partners, and others, with PR-related education and training programs.
Defense Support of Civil Authorities (DSCA) is the process by which United States military assets and personnel can be used to assist in missions normally carried out by civil authorities. These missions have included: responses to natural and man-made disasters, law enforcement support, special events, and other domestic activities. A recent example of the use of DSCA is the military response to Hurricane Katrina. DSCA is the overarching guidance of how the United States military can be requested by a federal agency and the procedures that govern the actions of the military during employment.
The Deployable Specialized Forces (DSF) —formerly Deployable Operations Group— part of the United States Coast Guard that provide highly equipped, trained and organized deployable specialized forces, to the Coast Guard, United States Department of Homeland Security (DHS), United States Department of Defense (DoD) and inter-agency operational and tactical commanders. The command was formerly headquartered in Arlington, Virginia, it was established on 20 July 2007, and was commanded by a captain, the command was decommissioned by the Commandant of the Coast Guard, Admiral Robert Papp on 1 October 2013, although many of the units existed long before the 2007 commissioning. Upon decommissioning the command, the units previously assigned to the DOG were split between Coast Guard Pacific and Atlantic Area commands. The units were soon reorganized under Deployable specialized forces (DSF).
The 710th Combat Operations Squadron is a reserve unit, stationed at Joint Base Langley-Eustis, Virginia, where it has augmented the 610th Air Operations Center since its activation in March 2004. Its first predecessor was established in Alaska in 1952 as the 710th Aircraft Control and Warning Squadron and provided air defense radar coverage until inactivating in 1983. The two squadrons were consolidated in June 2004.
The Joint Theater Level Simulation (JTLS) is used to simulate joint, combined, and coalition civil-military operations at the operational level. Used for civil/military simulations and humanitarian assistance/disaster relief (HA/DR) scenarios, JTLS is an interactive, computer-assisted simulation that models multi-sided air, ground, and naval resources with logistical Special Operation Forces (SOF) and intelligence support. The primary purpose of JTLS is to create a realistic environment in which agency staff can operate as they would within a real-world or operational situation. A training audience conducts a scenario or event to practice their ability to coordinate various staff functions.
A battle lab or battle laboratory is an organization dedicated to studying changes in the military.
