The mission of USFK is to support theUnited Nations Command (UNC) and Combined Forces Command by coordinating and planning among U.S. component commands, and exercise operational control of U.S. forces as directed byUnited States Indo-Pacific Command. In addition, USFK is responsible for organizing, training and equipping U.S. forces on the Korean Peninsula, as well as executing ancillary functions such asnon-combatant evacuation operations.
TheU.S. military presence in South Korea is extensive, including at least 24,234 active-duty soldiers, sailors, airmen, and marines as well as nine major bases.[1]
While USFK is a separate organization fromUnited Nations Command (UNC) andROK/US Combined Forces Command (CFC), its mission is to support both UNC and CFC by coordinating and planning among US component commands and providing US supporting forces to the CFC. As such, USFK continues to support the ROK-US Mutual Defense Treaty.
In response to the North Korean attack against South Korea on 25 June 1950, the United Nations Security Council (UNSC) established the UNC as a unified command under the US in UNSC Resolution 84 on 7 July 1950. The UNC mission was to assist South Korea to repel the attack and restore international peace and security in Korea. Throughout the war, 53 nations provided support to the UNC; 16 nations provided combat forces and five sent medical and hospital units. After three years of hostilities, the commanders of both sides signed the Armistice Agreement on 27 July 1953.
Hostilities today are also deterred by this bi-national defense team that evolved from the multi-national UNC. Established on 7 November 1978, theROK/US Combined Forces Command (CFC) is the warfighting headquarters. Its role is to deter, or defeat if necessary, outside aggression against the ROK.
The following is a partiallist of border incidents involving North Korea since theArmistice Agreement of 27 July 1953, ended large scale military action of theKorean War. Most of these incidents took place near either theKorean Demilitarized Zone or theNorthern Limit Line. This list includes engagements on land, air and sea but does not include alleged incursions and terrorist incidents that occurred away from the border.
Many of the incidents occurring at sea are due to border disputes. The North claims jurisdiction over a large area south of the disputed western maritime border, the Northern Limit Line in thewaters west of the Korean Peninsula. This is a prime fishing area, particularly for crabs, and clashes commonly occur. In addition, the North claims its territorial waters extend for 50 nautical miles (90 km) from the coast, rather than the 12 nautical miles (22 km) recognized by other countries. According to the 5 January 2011Korea Herald, since July 1953 North Korea has violated the armistice 221 times, including 26 military attacks.[8]
16 February 1958: North Korean agents hijack a South Korean airliner to Pyongyang en route from Pusan to Seoul; one American pilot, one American passenger, two West German passengers and 24 other passengers were released in early March, but eight other passengers remained in the North.[9]
May 1962: Pvt.Larry Allen Abshier abandoned his post in South Korea in May 1962 when he crept away from his base and crossed the DMZ into North Korea. Abshier was the first to defect. Also in May 1962,Cpl.Jerry Parrish crossed the DMZ into North Korea. His reasons for defecting, according to Jenkins' autobiographyThe Reluctant Communist, were "personal, and [Parrish] didn't elaborate about them much except to say that if he ever went home, his father-in-law would kill him."[10]
Aug 1962:James Joseph Dresnok was aPfc. with aU.S. Army unit along theKorean Demilitarized Zone. Soon after his arrival he found himself facing acourt martial for forging signatures on paperwork that gave him permission to leave base and which, ultimately, led to his beingAWOL (Absent Without Official Leave).[11] Unwilling to face punishment, on 15 August 1962, while his fellow soldiers were eating lunch, he ran across aminefield in broad daylight into North Korean territory, where he was quickly apprehended by North Korean soldiers. Dresnok was taken by train toPyongyang, the North Korean capital, and interrogated.[12]
1964: North Korea creates an underground group: Revolution Party for Reunification. This group is ground down and eliminated by South Korean authorities by 1969[13]
Jan 1965:Charles Jenkins, the most notable case, defected to North Korea. In South Korea he was assigned to night patrols. As a result of fears that he would be transferred to combat duty inVietnam, he grew depressed and anxious, and started drinking alcohol. On the night of 4 January 1965, after reportedly drinking ten beers, he set off on his nightly patrol of the Demilitarized Zone. In the early morning he told his patrol that he was going to investigate a noise.[14] He subsequently crossed into North Korea and surrendered to forces there, in hopes of being sent to Russia and then, through prisoner exchange, eventually returned to America. Shortly thereafter North Koreanpropaganda declared that a U.S. sergeant had defected, and broadcast statements allegedly made by thedefector, reportedly in stilted English. The U.S. Army claimed Jenkins wrote four letters stating his intention to defect (an allegation Jenkins denies); however, the original letters are reportedly lost. His relatives maintained throughout his absence that he was abducted.[14]
17 January 1968: In an incident known as theBlue House Raid, a 31-man detachment from theKorean People's Army secretly crossed the DMZ on a mission to kill South KoreanPresidentPark Chung Hee on 21 January, nearly succeeding. The incursion was discovered after South Korean civilians confronted the North Koreans and informed South Korean authorities. After enteringSeoul disguised asSouth Korean soldiers, the North Koreans attempt to enter theBlue House (the official residence of the President of South Korea). They are confronted bySouth Korean police and a firefight ensued. The North Koreans fled Seoul and individually attempted to cross the DMZ back to North Korea. Of the original group of 31 North Koreans, 28 were killed, one was captured and two are unaccounted for. Additionally, 68 South Koreans were killed and 66 were wounded, the majority of whom were soldiers and police officers. Three American soldiers were also killed and three were wounded.[17]
23 January 1968: TheUnited States Naval ship theUSSPueblo is boarded and captured, along with its crew, by North Korean forces in thewaters east of the Korean Peninsula. The entire crew of 83 is captured, with the exception of one sailor killed in the initial attack on the vessel, and the vessel was taken to a North Korean port. All the captives were released on 23 December of the same year via theBridge of No Return at the DMZ. The USSPueblo is still in North Korean possession and is docked inPyongyang and is on display as amuseum ship.[18]
30 October 1968: From 30 October-2 November 120–130 North Korean commandos land on the northeast shore of South Korea, allegedly to establish a base in order to wage a guerrilla war against the South Korean government.

Number of U.S. soldiers stationed in South Korea by year
Each year the ROK, the US and a selection of Sending States from the United Nations Command participate in multiple defense-oriented, combined and joint training events designed to defend the Republic of Korea, protect the region, and maintain and increase stability on the Korean peninsula.
A U.S. Air Force B-52 Stratofortress conducted a low-level flight in the vicinity of Osan Air Base, South Korea.
Ulchi-Freedom Guardian (UFG) is an annual simulation driven, command transformation-oriented Command Post Exercise (CPX). Elements of the ROK and US governments participate, as well as ROK and US forces from on and off the Korean peninsula. UFG integrates the annual ROK government exercise "Ulchi", which focuses on procedures for transitioning to war, government support. Ulchi also emphasizes ROK procedures for coordination between government and military organizations from the national to local level. UFG typically incorporates the following components: a Crisis Management Exercise focused on strategic and operational decisions needed to defuse a crisis, or posture the command for successful execution of the appropriate OPLAN if the enemy actions dictate; a Senior Leader Seminar (SLS) designed to foster senior-level discussion on a variety of topics related to crisis management and war-fighting; and a two-week Computer Assisted Exercise that exercises the transition to war, defense, and counteroffensive phases of the war-fight. The exercise culminates in detailed senior leader level After-Action Reviews (AARs).
Key Resolve (KR) is over the course of a two-week-long CFC and ROK crisis management and war-fighting exercise. It provides invaluable opportunities to evaluate, train, and improves combined and joint coordination, procedures, plans and systems necessary for the conduct of contingency operations by ROK and US forces. It is a simulation driven Command Post exercise that exercises the defense of the ROK and the ability of the US to bring forces into the Theater of Operations to participate in that defense. The exercise culminates in detailed senior leader level AARs.
Foal Eagle (FE) is a series of component-sponsored joint and combined Field Training Exercises (FTX) that support training of OPLAN related tasks via participation of selected off-peninsula units. FE demonstrates US power projection and rapid deployment capabilities and is conducted concurrently, but not linked to, the KR CPX. Tactical units are the primary FE FTX training audience exercising all aspects of CFC's mission; rear area security, support operations, RSOI, special operations, ground maneuver, expeditionary operations, air combat operations, and maritime operations.
In June 2018 the South Korea and the US claimed they are ready to stop the conducting of military drills in order to create significant opportunities for the negotiations with DPRK.[36]
A shield-shaped embroidered device3+1⁄8 inches (7.9 cm) in height and2+1⁄2 inches (6.4 cm) in width overall blazoned: azure, in chief four mullets bendwise argent, all above a stylizedAmerican bald eagle, issuant from sinister base volant to dexter chief; the eagle's body gules surmounted by two bendlets, wider at base, of the second throughout; head of the second, eyed of the field, leg and talons of the second grasping a laurel branch and seven arrows or. The entire shield shape is edged with a1⁄16-inch (0.16 cm) white border. Attached above the device is a designation band in scarlet inscribed "USFK" in white letters. The entire device is edged with a1⁄8-inch (0.32 cm) blue border.
The shield shape reflects the United States Forces Korea's steadfast commitment to help defend the sovereignty of South Korea. The abbreviation "USFK" stands for United States Forces Korea which activated on 1 July 1957. The four stars symbolize the service and contributions of the United States Army, United States Navy, United States Air Force, and the United States Marine Corps. The stylized American bald eagle represents cohesion and unity among the services. The laurel sprigs and arrows depict the mission of the United States Forces Korea to defeat aggression if necessary. Red, white, and blue are the colors of the flag of the United States of America. Red symbolizes hard work and honor, white represents innocence and purity, and blue refers to justice and perseverance. Yellow signifies wisdom and intuition.
Gwangju convinced a new generation of young [Koreans] that the democratic movement had developed not with the support of Washington, as an older generation of more conservative Koreans thought, but in the face of daily American support for any dictator who could quell the democratic aspirations of the Korean people. The result was an anti-American movement in the 1980s that threatened to bring down the whole structure of American support for the ROK. American cultural centers were burned to the ground (more than once in Gwangju); studentsimmolated themselves in protest ofReagan's support forChun [Doo-hwan].[39]
Fundamental to this movement was a perception of U.S. complicity in Chun's rise to power, and, more particularly, in theGwangju massacre itself. These matters remain controversial. It is clear, for example, that the U.S. authorized the Korean Army's 20th Division to re-take Gwangju – as acknowledged in a 1982 letter to theNew York Times by then-Ambassador Gleysteen.
[GeneralWickham], with my concurrence, permitted transfer of well-trained troops of the twentieth R.O.K.A. Division from martial-law duty in Seoul to Gwangju because law and order had to be restored in a situation that had run amok following the outrageous behavior of the Korean Special Forces, which had never been under General Wickham's command.[40]
However, as Gwangju Uprising editors Scott-Stokes and Lee note, whether the expulsion of government troops left the situation lawless or "amok" is very much open to dispute.
An expansion ofCamp Humphreys later in the decade served as a catalyst for theDaechuri Protests, drawing thousands of South Korean citizens,[42] resulting in occasional violent clashes and arrests.[43] Following a series of large protests against the U.S. and Republic of Korea governments' plan to expand Camp Humphreys and make it the main base for most U.S. troops in South Korea, residents of Daechuri and other small villages near Pyeongtaek agreed to a government settlement to leave their homes in 2006 and allow the base's expansion.[44][45] Compensation for the land averaged 600 million won (about US$600,000) per resident.[46]
With the relocation of the new USFK and UNC headquarters toCamp Humphreys (inPyeongtaek) on 29 June 2018, the USFK command and the majority of its subordinate units have officially moved out of the city of Seoul; headquarters are now 35 km (22 mi) further south.[47]
During theCOVID-19 pandemic, members of USFK, and other foreign nationals were reported to have no-mask parties atHaeundae Beach inBusan for theIndependence Day of 2020,[48] and theMemorial Day of 2021, despite local social distancing restrictions.[49] They engaged in unruly behavior, which included playing loud music, heavy drinking, and the shooting of firecrackers at locals.[50]
Despite its controversies, the USFK continues to maintain strong support from South Korean Citizens, who have voiced their support for U.S. Military presence within the country citing China and North Korea as major factors. Many South Korean Citizens have additionally voiced support on social media for Nuclear Armament if the U.S. were to withdraw its troops from the Peninsula.[51]
