- US Coast Guard
For over two centuries the U.S. Coast Guard has safeguarded our Nation’s maritime interests in the heartland, in the ports, at sea, and around the globe. We protect the maritime economy and the environment, we defend our maritime borders, and we save those in peril. This history has forged our character and purpose as America’s Maritime Guardian — Always Ready for all hazards and all threats.
Today’s U.S. Coast Guard, with nearly 42,000 men and women on active duty, is a unique force that carries out an array of civil and military responsibilities touching almost every facet of the U.S. maritime environment.
The Coast Guard's motto is Semper Paratus, meaning "Always Ready."
- U.S. Navy
The mission of the Navy is to maintain, train and equip combat-ready Naval forces capable of winning wars, deterring aggression and maintaining freedom of the seas.
What you will find here is a series of organizational charts designed to show the chain of command and the relationship of the three principal components of the Navy Department. The site map at the right demonstrates the paths you may follow.
You can select the chart you wish to go to by selecting from the map. Or, from the Overview, you can select the organizational chart for the Office of the Secretary of the Navy, the organizational chart for the Office of the Chief of Naval Operations, the organizational chart of the Shore Establishment, or the organizational chart for the Operating Forces.
At the top of each page is an explanation of the chain of command as it relates to that chart.
- U.S. Air Force
The mission of the United States Air Force is to fly, fight and win … in air, space and cyberspace.
To achieve that mission, the Air Force has a vision of Global Vigilance, Reach and Power. That vision orbits around three core competencies: developing Airmen, technology to war fighting and integrating operations. These core competencies make our six distinctive capabilities possible.
Air and Space Superiority
With it, joint forces can dominate enemy operations in all dimensions: land, sea, air and space.
Because of technological advances, the Air Force can attack anywhere, anytime and do so quickly and with greater precision than ever before.
Rapid Global Mobility
Being able to respond quickly and decisively anywhere we're needed is key to maintaining rapid global mobility.
The essence lies in the ability to apply selective force against specific targets because the nature and variety of future contingencies demand both precise and reliable use of military power with minimal risk and collateral damage.
The ability of joint force commanders to keep pace with information and incorporate it into a campaign plan is crucial.
Agile Combat Support
Deployment and sustainment are keys to successful operations and cannot be separated. Agile combat support applies to all forces, from those permanently based to contingency buildups to expeditionary forces.
The Air Force bases these core competencies and distinctive capabilities on a shared commitment to three values: Integrity first, Service before self, and Excellence in all we do.
- U.S. Army
The United States Army's Mission is:
-To provide protection for the United States and its interest by securing its airspace, land, and sea interest and jurisdictions.
-To provide support to civil authorities in order to provide the protection and support needed to sustain the United State's national interest and stability.
-To provide support during national emergencies by assisting civil authorities in maintaining emergency preparedness throughout the nation.
-To work in concert with the three other major branches of the US military—the Navy, the Marine Corps, and the Air Force. Navy ships transport Army troops, equipment, and supplies to bases overseas.
- U.S. Marines
The Marine Corps serves as a versatile combat element, and is adapted to a wide variety of combat operations. The Marine Corps was initially composed of infantry combat forces serving aboard naval vessels, responsible for security of the ship, its captain and officers, offensive and defensive combat during boarding actions, by acting as sharpshooters, and carrying out amphibious assaults. The Marines fully developed and used the tactics of amphibious assault in World War II, most notably in the Pacific Island Campaign.
