the Korean War, South Korea established a joint military partnership with the United States, termed the ROK-U.S. Alliance, as outlined by the Mutual Defense Treaty. During the Vietnam War, the ROK Army and ROK Marines were among those fighting alongside South Vietnam and the United States. In the 1970s, through the Park Chung-hee Administration's "Yulgok Plan(율곡사업)", South Korea began to build up self-reliant, national defense capability. During South Korea's period of rapid growth in the 1980s, the military modernized, benefiting from several government-sponsored technology transfer projects and indigenous defense capability initiatives. In the 1990s, "South Korean industries provided about 70 percent of the weapons, ammunition, communications and other types of equipment, vehicles, clothing, and other supplies needed by the military." Today, the South Korean armed forces enjoy a good mix of avant-garde as well as older conventional weapons. Its capabilities include many sophisticated Western weapon systems, complemented by a growing and increasingly more advanced indigenous defense manufacturing sector. For example, by taking advantage of the strong local shipbuilding industry, the ROK Navy has embarked on a rigorous modernization plan with ambitions to become a blue-water navy in the 2020s. Future The ROK military forces are undergoing some preparation for assuming wartime operational control of the ROK's defenses. Several cutting-edge military systems are currently being inducted. Based on the Moon Jae-in Administration's 'Defense Reform 2.0(국방개혁 2.0)' and in line with the overall troop drawdown scheme, the number of generals and admirals will be reduced by 17 percent from the current 436 to 360 by 2022 to reduce the bloated top command apparatus. This means the removal of 66 general-level positions for the Army and five each for the Navy and Air Force. At the same time, the ROK Armed Forces will see a reduction in active duty personnel from 640,000 to 517,000, and the length of compulsory military service will also be reduced to 18 – 22 months by 2022. 'Defense Reform 2.0' is also intended to make the ROK military more independent to prepare for the ROK military retaining operational control authority in wartime (OPCON transfer), rather than American general taking command. Initial operational control capability was verified in 2019, with full operational capability planned for 2021, and full mission capability planned for 2022.
