The United States Coast Guard (USCG) is the coastal defense and maritime law enforcement branch of the United States Armed Forces[6] and one of the country's seven uniformed services. The Coast Guard is a maritime, military, multi-mission service unique among the U.S. military branches for having a maritime law enforcement mission (with jurisdiction in both domestic and international waters) and a federal regulatory agency mission as part of its mission set. It operates under the U.S. Department of Homeland Security during peacetime, and can be transferred to the U.S. Department of the Navy by the U.S. President at any time, or by the U.S. Congress during times of war. This has happened twice: in 1917, during World War I, and in 1941, during World War II.[7][8]

Created by Congress on 4 August 1790 at the request of Alexander Hamilton as the Revenue-Marine, it is the oldest continuous seagoing service of the United States.[Note 1] As Secretary of the Treasury, Hamilton headed the Revenue-Marine, whose original purpose was collecting customs duties in the nation's seaports. By the 1860s, the service was known as the U.S. Revenue Cutter Service and the term Revenue-Marine gradually fell into disuse.[9]

The modern Coast Guard was formed by a merger of the Revenue Cutter Service and the U.S. Life-Saving Service on 28 January 1915, under the U.S. Department of the Treasury. As one of the country's five armed services, the Coast Guard has been involved in every U.S. war from 1790 to the Iraq War and the War in Afghanistan.[10][11]

The Coast Guard has 40,992 men and women on active duty, 7,000 reservists, 31,000 auxiliarists, and 8,577 full-time civilian employees, for a total workforce of 87,569.[2] The Coast Guard maintains an extensive fleet of 243 coastal and ocean-going patrol ships, tenders, tugs and icebreakers called "cutters", and 1650 smaller boats, as well as an aviation division consisting of 201 helicopters and fixed-wing aircraft.[12] While the U.S. Coast Guard is the smallest of the U.S. military service branches in terms of membership, the U.S. Coast Guard by itself is the world's 12th largest naval force.[13][14]

The Coast Guard carries out three basic roles, which are further subdivided into eleven statutory missions. The three roles are:

With a decentralized organization and much responsibility placed on even the most junior personnel, the Coast Guard is frequently lauded for its quick responsiveness and adaptability in a broad range of emergencies. In a 2005 article in Time magazine following Hurricane Katrina, the author wrote, "the Coast Guard's most valuable contribution to [a military effort when catastrophe hits] may be as a model of flexibility, and most of all, spirit." Wil Milam, a rescue swimmer from Alaska told the magazine, "In the Navy, it was all about the mission. Practicing for war, training for war. In the Coast Guard, it was, take care of our people and the mission will take care of itself."[15]

The eleven statutory missions as defined by law are divided into homeland security missions and non-homeland security missions:[16]

While the U.S. Coast Guard Search and Rescue (CG-SAR) is not the oldest search and rescue organization in the world, it is one of the Coast Guard's best-known operations.[18] The National Search and Rescue Plan designates the Coast Guard as the federal agency responsible for maritime SAR operations, and the United States Air Force as the federal agency responsible for inland SAR.[19] Both agencies maintain rescue coordination centers to coordinate this effort, and have responsibility for both military and civilian search and rescue.[20] The two services jointly provide instructor staff for the National Search and Rescue School that trains SAR mission planners and coordinators. Previously located on Governors Island, New York, the school is now located at Coast Guard Training Center Yorktown at Yorktown, Virginia.

National Response Center

Operated by the Coast Guard, the National Response Center (NRC) is the sole U.S. Government point of contact for reporting all oil, chemical, radiological, biological, and etiological spills and discharges into the environment, anywhere in the United States and its territories.[21] In addition to gathering and distributing spill/incident information for Federal On Scene Coordinators and serving as the communications and operations center for the National Response Team, the NRC maintains agreements with a variety of federal entities to make additional notifications regarding incidents meeting established trigger criteria. The NRC also takes Maritime Suspicious Activity and Security Breach Reports. Details on the NRC organization and specific responsibilities can be found in the National Oil and Hazardous Substances Pollution Contingency Plan.[22] The Marine Information for Safety and Law Enforcement (MISLE) database system is managed and used by the Coast Guard for tracking pollution and safety incidents in the nation's ports.

National Maritime Center

The National Maritime Center (NMC) is the merchant mariner credentialing authority for the USCG under the auspices of the Department of Homeland Security. To ensure a safe, secure, and environmentally sound marine transportation system, the mission of the NMC is to issue credentials to fully qualified mariners in the United States maritime jurisdiction.[23]

Authority as an armed service

The five uniformed services that make up the U.S. Armed Forces are defined in Title 10 of the U.S. Code:

The term "armed forces" means the Army, Navy, Air Force, Marine Corps, and Coast Guard.[24]

The Coast Guard is further defined by Title 14 of the United States Code:

The Coast Guard as established January 28, 1915, shall be a military service and a branch of the armed forces of the United States at all times. The Coast Guard shall be a service in the Department of Homeland Security, except when operating as a service in the Navy.[25]

Coast Guard organization and operation is as set forth in Title 33 of the Code of Federal Regulations.

On 25 November 2002, the Homeland Security Act was signed into law by U.S. President George W. Bush, designating the Coast Guard to be placed under the U.S. Department of Homeland Security. The transfer of administrative control from the U.S. Department of Transportation to the U.S. Department of Homeland Security was completed the following year, on 1 March 2003.[26][27][28]

The U.S. Coast Guard reports directly to the Secretary of Homeland Security. However, under § 3 as amended by section 211 of the Coast Guard and Maritime Transportation Act of 2006, upon the declaration of war and when Congress so directs in the declaration, or when the President directs, the Coast Guard operates under the Department of Defense as a service in the Department of the Navy.

As members of the military, Coast Guardsmen on active and reserve service are subject to the Uniform Code of Military Justice and receive the same pay and allowances as members of the same pay grades in the other uniformed services.

The service has participated in every major U.S. conflict from 1790 through today, including landing troops on D-Day and on the Pacific Islands in World War II, in extensive patrols and shore bombardment during the Vietnam War, and multiple roles in Operation Iraqi Freedom. Maritime interception operations, coastal security, transportation security, and law enforcement detachments have been its major roles in recent conflicts in Iraq.

On 17 October 2007, the Coast Guard joined with the U.S. Navy and U.S. Marine Corps to adopt a new maritime strategy called A Cooperative Strategy for 21st Century Seapower that raised the notion of prevention of war to the same philosophical level as the conduct of war.[29] This new strategy charted a course for the Navy, Coast Guard and Marine Corps to work collectively with each other and international partners to prevent regional crises, man-made or natural, from occurring, or reacting quickly should one occur to avoid negative impacts to the United States. During the launch of the new U.S. maritime strategy at the International Seapower Symposium at the U.S. Naval War College in 2007, Coast Guard Commandant Admiral Thad Allen said the new maritime strategy reinforced the time-honored missions the service has carried out in the United States since 1790. "It reinforces the Coast Guard maritime strategy of safety, security and stewardship, and it reflects not only the global reach of our maritime services but the need to integrate and synchronize and act with our coalition and international partners to not only win wars ... but to prevent wars," Allen said.[29]

Authority as a law enforcement agency

The drugs were seized in three separate busts near Central America. The offload included approximately 38,000 pounds of cocaine seized in the largest cocaine bust in maritime history.

Title 14 USC, section 2 authorizes the Coast Guard to enforce U.S. federal laws.[30] This authority is further defined in § 89, which gives law enforcement powers to all Coast Guard commissioned officers, warrant officers, and petty officers.[31] Unlike the other branches of the United States Armed Forces, which are prevented from acting in a law enforcement capacity by § 1385, the Posse Comitatus Act, and Department of Defense policy, the Coast Guard is exempt from and not subject to the restrictions of the Posse Comitatus Act.[32]

Further law enforcement authority is given by § 143 and § 1401, which empower U.S. Coast Guard active and reserve commissioned officers, warrant officers, and petty officers as federal customs officers.[33][34] This places them under § 1589a, which grants customs officers general federal law enforcement authority, including the authority to:

(1) carry a firearm;
(2) execute and serve any order, warrant, subpoena, summons, or other process issued under the authority of the United States;
(3) make an arrest without a warrant for any offense against the United States committed in the officer's presence or for a felony, cognizable under the laws of the United States committed outside the officer's presence if the officer has reasonable grounds to believe that the person to be arrested has committed or is committing a felony; and
(4) perform any other law enforcement duty that the Secretary of Homeland Security may designate.

The U.S. Government Accountability Office Report to the House of Representatives, Committee on the Judiciary on its 2006 Survey of Federal Civilian Law Enforcement Functions and Authorities, identified the Coast Guard as one of 104 federal components that employed law enforcement officers.[36] The report also included a summary table of the authorities of the Coast Guard's 192 special agents and 3,780 maritime law enforcement boarding officers.[37]

Coast Guardsmen have the legal authority to carry their service-issued firearms on and off base. This is rarely done in practice, however; at many Coast Guard stations, commanders prefer to have all service-issued weapons in armories when not in use. Still, one court has held in the case of People v Booth that Coast Guard boarding officers are qualified law enforcement officers authorized to carry personal firearms off-duty for self-defense.[38]

Title 14 USC, section 2, 14 U.S.C. § 89, 18 U.S.C. § 1385 and the case of People v. Booth mentioned above all served to codify what had been long standing informal practice during the Coast Guard's long residence in the Department of Transportation. During this period USCG commissioned, chief petty and petty officers occasionally served as Law Enforcement officers at several levels with arrest authority both on and off duty and also enforced border and immigration law within a maritime context. By moving to Homeland Security, members of the Coast Guard were effectively made into one of the more powerful law enforcement officials simply because of the broad range of their legal mission and authority.
