Korea's military history spans thousands of years, beginning with the ancient nation of Gojoseon and continuing into the present day with the countries of North Korea and South Korea, and is notable for its many successful triumphs over invaders.
During the Cold War, South Korean troops actively participated in the Vietnam War, contributing the second largest foreign military contingent after the United States.[17] North Korea also contributed soldiers, military equipment and advisors to several conflicts during the Cold War in support of the Communist bloc, including the Yom Kippur War, Ethiopian Civil War, and Ugandan Bush War.[18][19][20]
Today, both North Korea and South Korea field some of the largest and most lethal armies in the world. On one hand, North Korea is widely suspected of having nuclear weapons, as well as other weapons of mass destruction. South Korea, for its part, is equipped with a sophisticated conventional military with state-of-the-art weapons. South Korea currently serves in several UN peacekeeping missions around the world. The South Korean military enjoys military alliances with other countries, particularly the United States.

"Then, in 371, Paekche struck northward into the Koguryŏ domain as far as Pyŏngyang, killing the Koguryŏ king, Kogugwŏn, in the course of the campaign. Paekche thus came to hold sway over a sizeable portion of the Korean Peninsula, including all the modern provinces of Kyŏnggi, Ch'ungch'ŏng, and Chŏlla, as well as parts of Hwanghae and Kangwŏn. Furthermore, King Kŭn Ch'ogo solidified his international position by making overtures to the Eastern Chin state in the Yangtze river region and to the Wa people in Japan."

Chinese histories record that Liu was victorious and forced the king of Silla to sue for peace, while Korean historians report the defeat of the Chinese armies. The fact that the Tang government found it necessary to withdraw the headquarters of its Korean protectorate to the Liao River valley in the early months of 676 suggests that the Korean version is probably closer to the truth. Silla was left in uncontested control of almost the whole of the Korean peninsula, and there was no great Tang campaign to recover what had been won with such difficulty and so quickly lost."

"Using his official position and his immense military influence, Jang Bo-go amassed substantial wealth by controlling maritime trade between Silla, Tang and Japan. The famous American scholar of Asian history, Edwin O. Reischauer hailed Jang Bo-go as the trade prince of the maritime commerce empire. As Jang emerged as a formidable force in the sea, high-ranking officials in the Silla capital, Gyeongju, could no longer ignore him. Jang Bo-go ruled his domain with absolute political, military and economic autonomy."
