Geography

South Korea occupies the southern portion of the*Korean Peninsula, which extends some 1,100*km (680*mi) from the Asian mainland. This mountainous peninsula is flanked by theYellow Sea*to the west, and*Sea of Japan*(East Sea) to the east. Its southern tip lies on the*Korea Strait*and the*East China Sea.

The country, including all its islands, lies between latitudes*33°*and*39°N, and longitudes124°*and*130°E. Its total area is 100,032 square kilometers (38,622.57*sq*mi).

South Korea is divided into four general regions: an eastern region of high mountain ranges and narrow*coastal plains; a western region of broad coastal plains,*river basins, and rolling hills; a southwestern region of mountains and valleys; and a southeastern region dominated by the broad basin of the*Nakdong River.

South Korea's terrain is mostly mountainous, most of which is not*arable.*Lowlands, located primarily in the west and southeast, make up only 30% of the total land area.

Some three thousand islands, mostly small and uninhabited, lie off the western and southern coasts of South Korea.*The largest island, Jeju-do,*is about 100 kilometers (about 60*mi) off the southern coast of South Korea. With an area of 1,845 square kilometers (712*sq*mi). Jeju-do is also the site of South Korea's highest point:*Hallasan, an extinct*volcano, reaches 1,950 meters (6,398*ft)*above sea level. The easternmost islands of South Korea include Ulleungdo and Liancourt Rocks*(Dokdo), while*Marado*and Socotra Rock*are the southernmost islands of South Korea.

Climate
South Korea tends to have a*humid continental climate*and a*humid subtropical climate, and is affected by the*East Asian monsoon, with*precipitation*heavier in summer during a short rainy season called*jangma, which begins at the end of June through the end of July. Winters can be extremely cold with the minimum temperature dropping
below*-20 °C*(-4*°F)*in the inland region of the country: in Seoul, the average January temperature range is -7*to*1*°C (19*to 34*°F), and the average August temperature range is 22*to*30*°C (72*to 86*°F). Winter temperatures are higher along the southern coast and considerably lower in the mountainous interior.*Summers can be uncomfortably hot and humid, with temperatures exceeding*30 °C (86*°F)*in most parts of the country. South Korea has four distinct seasons; spring, summer, autumn and winter. Spring usually lasts from late-March to early- May, summer from mid-May to early-September, autumn from mid-September to early-November, and winter from mid-November to mid-March.

Rainfall is concentrated in the summer months of June through September. The southern coast is subject to late summer*typhoons*that bring strong winds and heavy rains. The average annual precipitation varies from 1,370 millimeters (54*in) in Seoul to 1,470 millimeters (58*in) in Busan (Pusan).

Defense Structure
The Republic of Korea (ROK) has a strong presidential form of government. The ROK president is the constitutional commander of the nation’s armed forces; he also heads the State Council (cabinet) which is the highest administrative organ and includes the minister of national defense.

The president is assisted by the National Security Council, of which he is the chairman and which includes the prime minister, the ministers of national defense, economic planning, foreign affairs, home affairs, and finance and the director of the Central Intelligence Agency. The chairman of the Joint Chiefs of Staff also participates in NSC meetings. General control over the armed forces is exercised by the Joint Chiefs of Staff, who are administratively responsible to the national defense minister.

Politico-Military Policy
The current primary objective of the Republic of Korea is to maintain its independence in the face of the ever present invasion threat from Communist North Korea. A less realistic goal is to overthrow the North Korean regime, regarded as the illegal occupier of the north, and reunite the Korean peninsula under the South Korean government. The first policy is strongly supported by the United States. The United Nations, which is pledged to defend the ROK from aggression, also supports Korea’s peaceful reunification under UN-supervised free elections.

Any such peaceful reunification seems precluded in the foreseeable future. North Korea’s independence and military strength are supported by both the Soviet Union and the People’s Republic of China. The military establishments of North and South Korea, backed by alliances with the world’s greatest powers, are poised in an uneasy deadlock which neither dares break. High level discussions between representatives of the two Korean governments are not fruitful for a variety of reasons, all rooted in the almost total distrust that each side feels for the other.

Meanwhile, South Korea seeks to increase its military and economic strength and decrease its dependence on the United States. The 1968 North Korean attempt to assassinate the ROK president, the capture of the U.S. intelligence ship Pueblo, the shooting down by North Korean aircraft of a U.S. EC-121 aircraft over international waters on April 15, 1969, caused a rapid modernization of the South Korean and American forces defending the ROK. The ROK also benefited from its contribution of 50,000 troops in Vietnam, which resulted in increased U.S. aid and promises of profitable reconstruction in South Korea.

Military service is compulsory for all physically fit adult males. After completing service (thirty-three months of the army and marines and thirty-six months for the navy and air force), the individual is automatically a member of the reserve force.

Strategic Problems
South Korea’s main strategic vulnerability is the proximity of all ROK targets, including concentrated industries and population centers, to air attacks from North Korea, Communist China and the Soviet Union. The ROK is also vulnerable to ground infiltration or attack from the north. South Korea has taken energetic measures against constant North Korean infiltration and sabotage, including the forming of special counter-insurgency units, intensive coastal patrols and a home guard militia. In view of the strong anticommunism of the majority of South Koreans, and their general support of the ROK government, there is little likelihood of indigenous guerrilla warfare arising, although civil disturbances are not uncommon. With continued U.S. military commitment and the maintenance of a strong ROK defense structure, the chances of an all-out attack from North Korea are slight. Should the Korean War be renewed, there is little chance of either side mounting a quick knockout blow.

The artificial division of the Korean peninsula in 1945 left the South with the agricultural, unindustrialized portion of the country and the less educated and more unskilled part of the population. Movement from rural to urban areas subsequently increased economic problems. In recent years, however, there has been a boom in exports, which has helped to reduce the large gap in balance of payments.

Military Assistance
The ROK military forces are very dependent on U.S. aid. American military assistance from 1946 through 1977 amounted to $4.9 billion. The U.S. has improved the weapons of the ROK armed forces and enlarged and updated the ROK Air Force. The U.S. maintains military advisory groups in Korea which equip and train all four ROK services. Most of South Korea’s military units are under the operational control of the United Nations Command, which is Korea’s senior military headquarters. The UN Commander is also the commanding general of the U.S. Eighth Army

Alliances
The ROK-US alliance, embodied in the Mutual Defense Treaty of November 1954, provides that the parties will consult each other if threatened by external attack. The treaty also states that an armed attack on the Pacific territories controlled by either signatory would be dangerous to the security of the other.

Soviet and U.S. opposition has kept both Koreas out of the United Nations. The ROK is a member of the Asian and Pacific Council (ASPAC), the Economic Commission for Asia and the Far East (ECAFE), the Food and Agriculture Organization of the United Nations (FAO), and the World Heath Organization (WHO). The ROK is also a founding member of the Asian Nations Anti-Communist League.

Republic of Korea Army
The*Republic of Korea Army*(ROKA; Daehanminguk Yuk-gun), also known as the*ROK Army, is the largest of the military branches of the*South Korean armed forces*with 540,000 members as of 1995. South Korea also maintains a Regular Army Reserve of 1,400,000 men, forming 23 infantry divisions and a Homeland Reserve Defense Force of 3,300,000 men that provides a variety of replacements and internal security units

Overview
The army is structured to operate in the mountainous terrain native to the*Korean Peninsula*(70% mountainous) The current administration has initiated a program over the next two decades to design a purely domestic means of self-defense, whereby*South Korea would be able to fully counter a*North Korean*attack.

The ROK Army is organized into 3 armies: the First Army (FROKA), Second Army (SROKA) and Third Army (TROKA) Each with its own headquarters, corps, and divisions. The Third Army is responsible for the defense of the capital as well as the western section of the*DMZ. The First Army is responsible for the defense of the eastern section of the DMZ whereas the Second Army forms an operational reserve as well as guards the remainder of the country.

History
The modern Korean Army traces its lineage back to the*Gwangmu Reform, when the*Beolgyegoon*was established by Emperor Gojong*in 1881. in The 1st of every October is celebrated in South Korea as the Armed Forces Day. It commemorates the day during the*Korean War*when units of the ROK Army first crossed the 38th Parallel, thus leading the UN Coalition north into North Korean territory for the first time.

Military ranks
Officer ranks can be learned fairly easily if one sees the pattern. "So" equals small; "Jung" equals medium; "Dae" equals large.

"Jun" equals equivalent, used for Warrant Officer and 1 star general to ensure that they are regarded as officer/general, although these ranks are lower than the same grade with "So" rank.

"Won" equals principal, only used for Won-Su, General of the Army.

Each of these is coupled with "wi" equals company grade, "ryung" equals field grade, and "jang" equals general.

NCO rank is same as officer. "Ha" (?) equals lower; "Jung" equals medium; "Sang" equals high; "Won" equals principal, because this title is named after Won-Su, to ensure that this rank is higher than Sang-sa.

Each of these is coupled with "Sa" equals sergeant, although actual 'sergeant' rank is "Byeong-jang".
This system is due to the*hanja*or*Sino-Korean*origin of the names.

Republic of Korea Air Force

The*Republic of Korea Air Force*(ROKAF;**Daehanminguk Gong-gun), also known as the*ROK Air Force, is under the South Korean Ministry of National Defense. The ROKAF has about 450 combat aircraft.

History
Early years
Shortly after the end of*World War II, the South Korean Air Construction Association was founded on August 10, 1946 to publicize the importance of air power. Despite the then-scanty status of Korean armed forces, the first air unit was formed on May 5, 1948 under the direction of Dong Wi-bu, the forerunner to the modern South Korean*Ministry of National Defense. On September 13, 1949, the*United States*contributed 10*L-4 Grasshopper observation aircraft to the South Korean air unit. An Army Air Academy was founded on January, 1949, and the ROKAF was officially founded on October, 1949.

Korean War
The 1950s were a critical time for the ROKAF as it expanded tremendously during theKorean War. At the outbreak of the war, the ROKAF consisted of 1,800 personnel but was equipped with only 20 trainer and*liaison aircraft, including 10*North American T-6 Texan advanced trainers purchased from*Canada. The North Korean air force*had acquired a considerable number of*Yak-9*and*La-7*fighters from the*Soviet Union, dwarfing the ROKAF in terms of size and strength. However, during the course of the war, the ROKAF acquired 110 aircraft: including 79 fighter-bombers, forming three fighter squadrons, and one fighter wing. The first combat aircraft received were*North American F-51D Mustangs, along with a contingent of*US Air Force*instructor pilots under the command of Major*Dean Hess, as part of*the Bout One*Project. The ROKAF participated in bombing operations and flew independent sorties. After the war, the ROKAF Headquarters was moved to Daebangdong,*Seoul. Air Force University was also founded in 1956.

1960s
To counter the threat of possible North Korean aggression, the ROKAF underwent a substantial capability enhancement. The ROKAF acquired*T-28*trainers,*F-86D*night- and all-weather interceptors,*F-5*fighters and*F-4D*fighter bombers. Air Force Operations Command was established in 1961 to secure efficient command and control facilities. Air Force Logistics Command was established in 1966, and emergency runways were constructed for emergency use during wartime. The Eunma Unit was founded in 1966 to operate*C-46*aircraft used to support*Republic of Korea Army*and*Republic of Korea Marine Corps*units serving in South Vietnam during the*Vietnam War.

1970s
The ROKAF was posed with a security risk, with an increasingly belligerent North Korea throughout the 1970s. The South Korean government increased its expenditure on the ROKAF, resulting in purchase of*F-5E*fighters in August 1974 and F-4E fighter bombers. Support aircraft, such as*C-123s*and*S-2s*were also purchased at the time. Great emphasis was placed in the flight training program; new trainer aircraft (T-41*and*T-37) were purchased, and the Air Force Education & Training Command was also founded in 1973 to consolidate and enhance the quality of personnel training.

1980s
The ROKAF concentrated on qualitative expansion of aircraft to catch up to the strength of North Korean Air Force. In 1982, Korean variants of the F-5E, the were first produced. The ROKAF gathered a good deal of information on the North Korean Air Force when Captain Lee Woong-pyeong, a North Korean pilot, defected to South Korea. The Korean Combat Operations Information center was soon formed and the Air Defense System was automated to attain air superiority against*North Korea. When the1988 Seoul Olympics*was held in*South Korea, the ROKAF contributed to the success of this event by helping to oversee the entire security system. The ROKAF also moved its headquarters and the Air Force Education & Training Command to other locations. Forty*F-16 Fighting Falcon*fighters were purchased in 1989.

1990s
South Korea committed its support for coalition forces during the*Persian Gulf War, forming the "Bima Unit" to fight in the war. The ROKAF also provided*airlift*support for peacekeeping operations in*Somalia*in 1993. The increased participation in international operations depicted the ROKAF's elevated international position. Over 180*KF-16*fighters of*F-16 Block 52*specifications were introduced as part of the Peace Bridge II & III program from 1994.

The South Korean variant the of*F-15E*were named the F-15K*Slam Eagle*due to their capability to launch the*SLAM-ER*missiles and Harpoon missiles.
