Key Resolve , previously known as Reception, Staging, Onward Movement, Integration ( RSOI ) which was previously known as Team Spirit even earlier, is an annual command post exercise (CPX) held by United States Forces Korea with the Republic of Korea Armed Forces . It is conducted between February and April and focuses on United States Pacific Command OPLANs that support the defense of South Korea . Additionally, US units are moved to Korea from other areas and they conduct maneuvers and gunnery exercises. ROK units also conduct maneuvers with some acting as the Opposing force (OPFOR). Since 2001, Key Resolve combined with the annual combined field training exercise (FTX) Foal Eagle .
28-695: Doctrinally, RSOI is detailed in FM 100-17-3 , the field manual for RSOI. This exercise, like the Ulchi-Freedom Guardian (UFG) exercise, regularly leads to accusations by North Korea that it is a prelude to an invasion by the United States and South Korea. Japan supports the joint drills of South Korea and the US, considering it to be a deterrent power in the Asian-Pacific region. After
56-414: A clear, unified command structure is essential. In Bosnia and Herzegovina , during Operation Deny Flight, a confusing dual-key coordination structure provided inadequate authority and resulted in air forces not being given authority to assist in key situations; Second, to avoid a "perpetual patrol problem", states must know in advance their policy objectives and the exit strategy for no-fly zones; Third, that
84-413: A crisis over successful North Korean missile tests and strong rhetoric by U.S. President Trump . The U.S. manpower contribution for the exercise was reduced from 25,000 in 2016 to 17,500. South Korean media reported that the U.S. had cancelled plans to deploy strategic assets in the exercise, such as aircraft carriers, nuclear-powered submarines or a B1 bomber . U.S. Forces Korea did not comment on
112-401: A military power over which certain aircraft are not permitted to fly. Such zones are usually set up in an enemy power's territory during a conflict for humanitarian or military reasons without consent of the enemy state, similar in concept to an aerial demilitarized zone , and usually intend to prohibit the enemy's military aircraft from operating in the region. Military action is employed by
140-556: Is generally not considered a form of aerial blockade due to its more limited scope compared to an aerial blockade. No-fly zones are a modern phenomenon established in the 1990s. They can be distinguished from traditional air power missions by their coercive appropriation of another nation's airspace only, to achieve aims on the ground within the target nation. While the Royal Air Force (RAF) conducted prototypical air control operations over various contentious colonies between
168-630: Is subject to the rules of armed conflict under international humanitarian law . Following the 1991 Gulf War , the United States along with other Coalition nations established two no-fly zones in Iraq. US and Coalition officials stated that the northern no-fly zone was intended to prevent attacks against the Kurdish people by the Iraqi regime of Saddam Hussein , and that the southern no-fly-zone
196-415: Is the name (as of 2015 ) of the military exercise previously known as Ulchi-Focus Lens , a combined military exercise between South Korea and the United States . The exercise is the world's largest computerized command and control implementation, involving 50,000 South Korean troops alongside 17,500 U.S. troops in 2017, and mainly focuses on defending South Korea from a North Korean attack. The exercise
224-565: The 32nd parallel , but was extended to the 33rd parallel in 1996. By 1999, over 1,800 bombs had reportedly been dropped on Iraq. This military action was not authorised by the United Nations . The Secretary-General of the United Nations at the time the resolution was passed, Boutros Boutros-Ghali called the no-fly zones "illegal" in a February 2003 interview with John Pilger for ZNet . In 1998, France withdrew from
252-480: The Banja Luka incident , the shooting down of at least four of a flight of six Serbian jets, occurred; the engagement was not only the first combat engagement of the operation, but also the first combat engagement in the history of NATO. NATO later launched air strikes during Operation Deny Flight and during Operation Deliberate Force . As many as 400 NATO aircraft participated in the air campaign. As part of
280-625: The Donetsk People's Republic claimed that Russia would establish a no-fly zone over the Donbas region of Ukraine. A 2004 Stanford University paper published in the Journal of Strategic Studies , "Lessons from Iraq and Bosnia on the Theory and Practice of No-fly Zones", reviewed the effectiveness of the air-based campaigns in achieving military objectives. The paper's findings were: First,
308-731: The North Korea–United States Hanoi Summit in February 2019, the United States Department of Defense announced that the United States and South Korea "decided to conclude the Key Resolve and Foal Eagle series of exercises". They were replaced by the Dong Maeng joint military exercise in 2019. Ulchi-Freedom Guardian Ulchi-Freedom Guardian (을지 프리덤 가디언, Eulji peurideom gadieon)
SECTION 10
#1732779962004336-658: The 2011 military intervention in Libya, the United Nations Security Council approved a no-fly zone on 17 March 2011. The resolution includes provisions for further actions to prevent attacks on civilian targets. On 24 March, NATO agreed to take control of the no-fly zone. Shortly thereafter, several NATO members proceeded to mount an aerial offensive campaign, in which numerous Libyan government positions would be intentionally bombed. Some NATO members did not contribute or did little to participate in
364-527: The Gulf War of 1991, it had not been possible to perform nuanced attacks against transitory, difficult-to-reach targets, and air power thus lacked the ability to produce decisive political effects short of total war. However, the demise of the Soviet Union and technological advances in aerospace capabilities made no-fly zones viable in both political and military contexts. Enforcement of a no-fly zone
392-590: The Military Demarcation Line (MDL). No fly zones was also established along the DMZ to ban the operation of drones, helicopters and other aircraft from coming within 10 to 40 km away from the MDL. In August 2019, a similar but scaled down exercise under an undisclosed name was carried out, mainly using computer simulations. The main scenario was South Korea taking over from the U.S. 90 days after
420-606: The air campaign, leading to public criticism from US Secretary of Defense Robert Gates . The NATO no fly zone was terminated on 27 October after a unanimous vote by the UNSC , despite requests made by the Libyan National Transitional Council for its mission to be extended to the end of the year. A no-fly zone was declared by the Tobruk -based LNA over the country's south during its offensive in
448-561: The alliance rejected the request on account of risking further escalation and direct military confrontation with Russia . There were also questions over the effectiveness of implementing such a zone for the purpose of protecting the Ukrainian settlements, which have been subject to heavy and indiscriminate attacks from Russian artillery and other largely ground-based forces. On 18 March, the Russian-backed separatist government of
476-461: The drills in South Korea. North Korea routinely denounces the exercise as preparation for war. On 20 August 2012, the exercise began between South Korea and the United States over the objections of North Korea. North Korea alleged that the drill was a precursor to a war planned against them. The North Korean foreign ministry stated that "the prevailing situation requires us to bolster up
504-493: The enforcing state and, depending on the terms of the NFZ, may include preemptive attacks to prevent potential violations, reactive force targeted at violating aircraft, or surveillance with no use of force. Air exclusion zones and anti-aircraft defences are sometimes set up in a civilian context, for example to protect sensitive locations, or events such as the 2012 London Olympic Games , against terrorist air attack. A no-fly zone
532-494: The no-fly zone but did not take action against violators of the resolution. In response to 500 documented violations by 1993, including one combat violation, the Security Council passed Resolution 816 , which prohibited all unauthorized flights and allowed all UN member states to "take all necessary measures ... to ensure compliance with [the no-fly zone restrictions]." This led to Operation Deny Flight , during which
560-752: The operation, with French Foreign Minister Hubert Vedrine saying that "there is no basis in international law for this type of bombing". The United Nations reported that in 1999 alone, 144 civilians had been killed during Coalition bombing efforts. An internal UN Security Sector report found that, in one five-month period, 41% of the victims were civilians. In 1992, the United Nations Security Council passed United Nations Security Council Resolution 781 , prohibiting unauthorized military flights in Bosnian airspace. This led to Operation Sky Monitor , where NATO monitored violations of
588-431: The outbreak of a war to carry out stabilization operations after North Korea has been neutralised. For the first time a South Korean General led the exercise. North Korea complained that the exercise violated U.S. President Donald Trump 's promise to halt major war games. No fly zone A no-fly zone , also known as a no-flight zone ( NFZ ), or air exclusion zone ( AEZ ), is a territory or area established by
SECTION 20
#1732779962004616-627: The reason. In 2018, the South Korean government cancelled that year's exercise. However, joint US-South Korean military exercises resumed again on November 5, 2018, though on a small scale compared to previous exercises. A buffer zone had been established across the Korean Demilitarized Zone on November 1, 2018 to prohibit both Koreas from conducting live-fire artillery drills and regiment-level field maneuvering exercises or those by bigger units within 5 kilometers of
644-515: The region in 2018. It was later re-implemented for 10 days in 2019 as the LNA established control over oil fields in the region. The LNA declared another no-fly zone across the country's west during the 2019 Western Libya offensive . Shortly after the start of the Russian invasion of Ukraine in February 2022, the Ukrainian leadership repeatedly urged NATO to enforce a no-fly zone over Ukraine, but
672-528: The two World Wars , no-fly zones did not assume their modern form until the end of the Gulf War in 1991. During the Cold War , the risk of local conflict escalating into nuclear showdown made military intervention as a tool of United States statecraft unappealing. Furthermore, air power was a relatively blunt instrument until the operational maturation of stealth and precision-strike technologies. Before
700-466: The war deterrent physically and goes to prove that it was entirely just when we determined to fully reexamine the nuclear issue." The United States Department of State countered, saying that North Korea must refrain from "bellicose statements." General James D. Thurman , added on, stating that Ulchi Freedom Guardian is "a key exercise in strengthening the readiness of Republic of Korea and U.S. forces." The 2017 exercise took place August 21–31, during
728-537: Was changed to Ulchi Yeonseup (을지연습, Ulchi Exercise) in the following year. In 1976, it was integrated with ROK-US Combined Forces Command 's military training, Focus Lens, into Ulchi-Focus Lens . The name of the exercise was changed again in 2008 to Ulchi-Freedom Guardian . The exercise has on occasion included contingents from Australia, Britain, Canada, Colombia, Denmark, the Netherlands and New Zealand. In 2022, thousands of protesters demonstrated against
756-535: Was initiated in 1976 and is conducted annually during August or September. The word 'Ulchi' comes from the name of a famous Korean general called Eulji Mundeok , who was the Commander-In-Chief of the army of Goguryeo . The origin of the exercise is Taeguk Yeonseup (태극연습, Taeguk Exercise), which began after the Blue House Raid by North Korean special forces in 1968. The title of the exercise
784-609: Was intended to protect Iraq's Shia population . On 16 March 1988, the Iraqi Air Force deployed chemical weapons against Kurdish civilians during the Halabja chemical attack , killing roughly 5,000. This air-to-ground event served as part of the motivation used by Coalition Forces in order to extend and expand the NFZs, as well as citing parts of Article 42 within the U.N. Charter . The southern no-fly zone originally extended to
