Background and overview

The history of the Korean Peninsula division

In 1876, Korea (the name was changed to the Korean Empire, commonly known as Korea), which was concluded by the Japanese pressure under the Japan-North Korea Treaty of Inequality, was raised over the control of the Korean peninsula in 1904. After the Russo-Japanese War, the inequality treaty was compelled by Japan in three steps, and in 1910 it was finally completely merged with Japan. The so-called annexation of Japan and Korea is the beginning of the “36-year history of the Japanese Emperor” that is often spoken by Koreans.
Japan's colonial era continued until 1945 when Japan was defeated in World War II. At this point, South Korea had an opportunity to become independent, but in the chaos of post-war processing over the new world order, the northern peninsula was supported by socialist camps such as the Soviet Union and China (Democratic People's Republic of Korea) The South was divided into South Korea supported by the liberal state camps such as the United States, and became a divided state within the framework of the East-West Cold War structure.

The outbreak of the Korean War and the truce

Then, on June 25, 1950, North Korea, which had a military advantage, launched a surprise attack on South Korea across the border, aiming for unification of the north and south by armed forces. The beginning of the Korean War, also known as the Korean upheaval.
At that time, there were many first-class tanks such as the T-34 on the North Korean side, but on the contrary, the Korean army did not have tanks or sufficient anti-tank weapons. This is due to the fact that the United States has not provided enough equipment to the Korean army, thinking that a North-South collision on the Korean Peninsula would be impossible for the time being. Also, the US military in Korea was not enough in terms of military power and equipment, and eventually the Korean side was pushed unilaterally and gradually caught up in the southern peninsula.
The US government decided to introduce the US military stationed in the occupation of Japan, the so-called advance military force, and the formation of UN troops (not official UN troops as defined by the UN Charter), including Australia, Britain, Turkey, Brazil and South Africa. Countries participated. The general commander of the US military and the UN military was Marshal Douglas MacArthur, commander of the US military stationed in Japan.
The U.S. and UN troops made a surprise attack on Incheon in the middle of the peninsula on September 15, 1950 and pushed behind the enemy's main force, thereby changing the flow of battle and driving the North Korean army close to the Chinese border succeeded in.
In response to this, China introduced the “Chinese People's Volunteer Army”, which was called a volunteer soldier, to push the UN troops back to the 38th line. The battle then went back and forth across the 38th line, but here MacArthur strongly asserted a nuclear weapon attack against the Chinese army and mainland China, was dismissed in opposition to President Truman, Ridgeway The general took over.
After all, in the ceasefire negotiations held at the Panmunjom store on July 27, 1953, a ceasefire was established by setting a military boundary along the 38th north latitude line. The truce is still ongoing. In other words, the Korean War is simply a “ceasefire”, there are virtually no borders, and the ceasefire line is merely a temporary “border”.

The threat of North Korea and the possibility of system collapse

After that, North Korea did not give up the north-south integration by armed forces, digging a number of secret tunnels (so-called southward tunnels) to cross the demilitarized zone (DMZ) set with a width of 4 km north-south along the military boundary, On January 21, 1968, an operative was introduced to attempt a guerrilla attack on the Cheong Wa Dae, South Korea's Cheong Wa Dae.
In addition, while conducting numerous terrorist acts, such as the Korean Aircraft Bombing and Rangoon Bombing, alleged nuclear weapons development, forced tepodon and nodon missile launch experiments and deployment, repeated submarine and suspicious ship intrusion cases, It has always been a fire and threat in Far East Asia, such as the abduction of Japanese people.
After the end of the Cold War, with the death of President Kim Il Sung in July 1994, his son, Kim Jong Il, succeeded the leader. In South Korea, Kim Dae-Jung, who had been a symbol of the anti-government movement, became the president, taking a reconciliation policy called the “sun policy” by turning away from the previous conflict.
From this time on, North Korea began to suffer from devastating agricultural production due to the collapse of the planned economy, floods, droughts, etc., making food shortages serious and becoming a famine. In contrast, the international community, including Japan, began to send rice and other relief supplies as humanitarian aid, but these have not reached the general public. For example, rice is considered to be resold and incorporated into the government budget, or alcoholized and used as fuel for power plants and tanks. At the same time, hunger refugees crossing China and South Korea and asylum seekers rushing to foreign diplomatic missions in China are rapidly increasing and becoming an international issue.
North Korea's system is now on the verge of collapse, and the possibility of the “unification” of the Korean Peninsula that North Korea has been aiming for is far away except when some troops runaway. There is also a view that there is not. However, even if the North Korean side gets stuck and begins to take a flexible route toward unification, the South Korean side cannot easily meet the unification.
Once the East and West Germany were united in October 1990, the German economy was forced to suffer huge economic losses to save the old East German citizens who suffered from poverty, and left a negative legacy of unemployment and worsening security. If the same thing happens between North and South Korea, there is concern that South Korea, which has not recovered sufficiently from the Asian economic crisis, can support it.

The Korean Peninsula as seen from China

China is the largest “friendly country” for North Korea, partly because it supported North Korea, the same socialist country, in the Korean War. In addition, the length of the border line with North Korea is the longest in the neighboring countries because it is in contact with the land. In addition, many Koreans live in the area along the North Korean border in Jilin and Liaoning provinces, and the number is said to be 20 million. Naturally, they have been actively engaged in trade activities with both the North and South Korea, both official and informal.
On the other hand, as in the case of exiles rushing to the Japanese Consulate General in Shenyang, there have been a series of exile cases in foreign diplomatic missions such as Beijing, Shanghai, and Shenyang. May have the same intimacy with the North Korean leadership who has no way of neglecting or doing this.
Also, if North Korea collapses and is unified in a way that is simply absorbed by South Korea, China has provided assistance to North Korea and special economic zones such as Shin-Yizhou. Not only will the investment be exposed to Korea, it will also lose the “buffer zone” of North Korea. China's anxiety and dissatisfaction with the dominance of the world by the great power of the United States is considerable, and if North Korea disappears and the United States military is stationed in South Korea after the unification, It will also be confronting the army directly. Furthermore, there is a high possibility that the borderline problem will be ignited over the continental shelf resources, etc. with Korea after the unification. After all, the current border between China and North Korea is set along the Kamo River and the Tumen River, but the area where Koreans actually live is more extensive.

Possibility of China moving when North Korea collapses

Neither South Korea, Japan nor the US has a clear vision regarding what schemes should be taken when North Korea collapses. On the other hand, China has a history of having the Korean peninsula as a member country for many years, and unexpectedly, it may happen that it will run into a North Korean annexed policy that it is easy to control. A common assumption regarding tensions between the North and South Korea is that it is common sense that the suffocating North Korean side will abandon the South to the South. However, the assumption of annexation of North Korea as depicted here is an ultra-C scenario, but it is a scenario that cannot be denied.
In that case, the moment when the US military strength in the Far East region declines is dangerous. The US military has recently declared abandonment of a system capable of coping with massive wars that occur simultaneously in two parts of the world. Therefore, when a big war that some US forces participate in somewhere in the world and the US forces in the Far East are rushed out, this possibility becomes a reality.

North Korea annexed and blocked unification

Scenario status settings

North Korea (Democratic People's Republic of Korea) has been revolting in the region, even with troops that have been preferentially allocated food, due to the long-standing economic crisis and food shortages. These were relatively small and were soon repressed. However, several sources said that the collapse of the country is nearing now that the military control that is the foundation for maintaining the power of the Korean Labor Party in the one-party dictatorship is not effective.
Refugee outflows to neighboring countries have increased dramatically due to political instability, which has long been an international problem and has been steadily worsening. The North Korean government was actively involved in the outflow in order to reduce mouths, but this was no longer an open secret. In particular, inflows into China were exceptional, and this has become a social problem in China.
The China-North Korea border continues on land and has the longest border line in the surrounding countries. Even in the same land, the South and North troops faced the border between South Korea and North Korea, and there were many artificial obstacles such as landmine sources and multiple wire strips on the border. Russia also responded sensitively to the increase in the influx of refugees, and responded strictly, such as the military blocking the border and shooting unlawfully with no warning. There were not enough ships to escape from the sea, and the Korean Navy, the Japan Coast Guard, the Maritime Self-Defense Force, and the Russian Navy cooperated to block the sea.
However, many Koreans lived on the Chinese side, and trade between the same ethnic groups was thriving. For this reason, the Chinese government mobilized troops and worked to close the border, but did not know where the inflow of refugees would end. The situation was also exacerbated by the fact that serpents, etc. received large amounts of money from asylum seekers and illegally sent refugees to Dalian, Lishun, Shanghai, etc. using cargo ships.
In spite of repeated protests against the North Korean government, the Chinese government, which has worked hard to prevent the situation from improving, has put in force measures to consolidate North Korea into its own country and make it an ethnic autonomous region. In other words, it was decided to become a country and to send the People's Liberation Army and security forces there, and to completely seize North Korea by having the Chinese side fully seized security.
The Chinese government was accused of hegemonism by the international community at the time of the merger, but “the merger was legally carried out to maintain the North Korean socialist system based on a formal request from the North Korean government. The reason why refugees have flown out to neighboring countries is the result of long-standing discussions on unified policies between the North and South Korea, and Japan is a victim. Announcing the president ’s discourse. In addition, the slogan was also justified to “unify” the Koreans that were divided at the border between China and North Korea.
But China's aim was not only to contain refugees. Rather, it was much greater that North Korea could significantly expand its territorial waters and exclusive economic zones in the Sea of ​​Japan and the Yellow Sea. On these continental shelves, not only marine resources but also many underground resources such as natural gas and manganese are sleeping untouched. The purpose was to obtain these resources.
For Yuan and North Korea, it is not a bad “business” because it is only necessary to block the border and put martial law to forbid the movement in China and supply even the minimum amount of food.
Also, I wanted to avoid the situation where North Korea's “buffer zone” with the western side was absorbed and unified by the western side of Korea.
Korea ’s position was delicate. The desire of unification of the people is strong, but if we have a broken North Korea that is no longer part of the nation, the economic burden will be astronomical and we will receive assistance from other countries, mainly Japan and the United States. But the Korean economy will fail.
However, the psychological pressure that directly touches borders with China, a socialist country, is intense, and I can't stand looting resources in the Sea of ​​Japan and the Yellow Sea. However, if the situation is left unattended, domestic public opinion will be beaten by saying "We have bowed to China."
In the end, the South Korean government protested the Chinese government withdrawing the merger and leaving the North Korea, saying, “This merger is nothing but an invasion / generalization that prevents ethnic independence”. However, the Chinese government did not deal with this, and began to send a large number of marine research vessels to the former North Korean territory. There were many demonstrations in South Korea that evacuated the government ’s weakness. It was obvious that the government would collapse and the country would become turbulent if it kept on.
The Korean government has reached this point and decided to “release” North Korea by force. After recapturing North Korea, it will be the federal state of South Korea and North Korea, and it will adopt a two-country system until the assimilation of North Korea's economic state and people's mentality progresses to some extent-that is, to maintain the state so far It was decided.
In addition, North Korea's troops that had been deployed on the Korean border until now were diverted to the Chinese border, and as a result, the defense burden on the Korean side, which used to be a semi-war system, was greatly reduced over time. There was also a reading that invested the Japanese budget in domestic industry, and aided North Korea received assistance from other countries such as Japan.
Although we had a secret discussion with the United States, the United States refused to cooperate with the U.S. forces in South Korea and restrained China from using nuclear weapons. Agreed to apply pressure.

About maps

In many games and novels dealing with this type of Second Korean War, North Korea uses a southward tunnel dug secretly to invade the suburbs of Seoul all at once. Many.
However, in this map, the point is that the South side uses the southward tunnel created by North Korea in reverse. However, due to program restrictions, the tunnel terrain does not have separate entrances. It is a reproduction of the shape of a large number of units housed in tunnel terrain like a hole and coming out from inside.
Although there are many Chinese troops, the ground forces of the PLA are mainly light infantry and not a threat. However, it is necessary to pay attention to the air force of the Chinese Air Force that the former North Korean armored units assumed to have been taken over from the merged North Korea are deployed along the Korean border.
It is important that the ground army quickly advance to the base secured by the airborne troops that hit these early and made a break in the front and sent them behind the enemy.

North Korea merger and U.S. military participation

Scenario status settings

It was a Chinese army that was confused by an unexpected surprise of the Korean army and responded to the back and occupied Pyongyang for a while, but it was rebuilt and the mechanized unit deployed on the `` border '' of China and North Korea The Air Force has been deployed in large numbers. The Chinese army has been overwhelming with the overwhelming forces, pushing the Korean army back from the 40th line with a saturated attack.
According to sources, the South Korean government planned to rebuild the former North Korean army deployed in the occupied area up to the 40th line, but it failed smoothly and failed, which was a major negative factor It's a pattern. There is also information that some North Korean special forces on the Chinese side are conducting small-scale guerrilla warfare in various places behind the battle line and attacking Korean troops, etc., causing unexpected damage.
In front of the overwhelming People's Liberation Army, the Korean army has been pushed back to the south of the 38th line. In addition, the Chinese army mobilized a number of small ships and secured a bridgehead by landing a navy infantry from the suburbs of Incheon as well as the remorse during the Korean War. They hold Gimpo and Incheon airports, use them as air bases, and make repeated attacks on enemy fronts with short-legged Chinese military aircraft, and continue to advance towards the fall of Seoul.
The US government, which was exhausted in the fight against Islamic extremists, initially refused to enter the war, but the South Korean army was too fragile, and the People's Liberation Army invaded across the border. The US military ’s largest base in the Far East, the buffer zone to Japan, will disappear ”and decided to participate.
The Korean army urged Seoul citizens to evacuate, and the ground forces were concentrated in the suburbs to save Seoul, and the government functions and headquarters were relocated to Ota. On the other hand, in the Yellow Sea, it seems that the Chinese Navy and the Korean Navy are fighting.
The U.S. Ground Forces and Air Force in Korea have already started joint operations with the Korean army. The US military in Japan has already landed the Okinawan Marine Corps in Busan, and the Okinawan Air Force and the Misawa Air Base Fighter Unit have also completed their launch and are deploying in Busan Airspace. The main fleet, the 7th Fleet, can also be deployed in the Sea of ​​Japan, and a part of the special forces can be infiltrated behind the 38th line with submarines.

About maps

This map is centered on the central Korean Peninsula.
Since South Korea has a lot of flat land forms, if Seoul falls, the Chinese army will soon come to Daejeon where the Korean military headquarters is located. To prevent this, it is effective to defend the soul and keep the enemy's troops nearby.
For the defense of Seoul, I would like to keep Gimpo and Incheon airports. For Incheon Airport, powerful naval forces should help. In ground battles, it is important to secure key traffic on the main road. Although the number is small, it is also important to make effective use of highly destructive weapons such as the latest ground missile system ATACMS.

North Korea merger / East China Sea Battle broke out

Scenario status settings

The US and South Korea have been forced to recede in the face of saturation attacks by the Chinese army that springs up one after another. Meanwhile, the US 7th Fleet, whose mainstay is the aircraft carrier Kitty Hawk, began moving from the Sea of ​​Japan toward the East China Sea.
Originally the US Navy Mobile Task Force boasting overwhelming air and striking power, it was impossible to introduce a large number of aircraft carriers only for this war due to operational actions in the Middle East and the Indian Ocean. Therefore, the 3rd Fleet and 5th Fleet could not be moved, and only the 7th Fleet was supported. In addition, the US Air Force and Marine Corps air units deployed over the Korean peninsula were almost fully supported by the Korean army and US forces in South Korea, and few units could be used as air covers for the 7th Fleet.
The Chinese army, who saw this as an opportunity, began to drive ballistic missiles into South Korea from the Yellow Sea coast. By directing these ballistic missiles to the attack target of the 7th Fleet, they will invite the 7th Fleet to the Yellow Sea and prepare for the decisive battle by preparing to crush the Yellow Sea Fleet with many old ships.
At this time, US government spokespersons have not made clear the purpose of the 7th Fleet movement, but among military personnel, support to the suburbs of the Seoul suburbs by the impact of the aircraft carrier and considerable damage to the US and South Korean ground forces There are multiple speculations, such as the destruction of ballistic missile bases on the coast of China, and the interception of logistics from the sea by the destruction of the Chinese main force.
Some military analysts said, “There are many Chinese naval bases such as Lushun, Qingdao, Shanghai on the Yellow Sea coast, and many anti-ship missiles and high-speed missile boats are deployed on the coast. "I'm underestimating my ability." However, a US Navy officer general said, “There are no worries because US troops can receive support from ground-based marines or air forces.”

About maps

This time the map is mainly naval battles. That said, there are no aircraft carriers in the Chinese army, and there are a lot of historical items on both surface and submarines. In effect, the Chinese army cannot fight naval battles without land support.
As you can see from the map, there are many important naval ports and harbors such as Lushun, Qingdao, Dalian and Shanghai on the coast of the Yellow Sea on the Chinese side.
Also, a small missile boat is hidden in the island shadow. Furthermore, the handy without an aircraft carrier is compensated with the air force of the Air Force.
[Here, in order for the US side to win, it is necessary to efficiently use air force units deployed over South Korea that can easily replenish the wear. Also, I want to take tactics such as carefully searching for enemies and sending Navy Special Forces Shields backward with a submarine.
In this scenario, since the Korean army is operated under the command of the US military, the Korean army as an independent camp does not appear.

North Korea annexation, Self-Defense Forces refugee rescue operation

Scenario status settings

The U.S. and South Korean troops were forced to take advantage of the guidance and protection of evacuees traveling south, falling into a chronic shortage of troops, and a large number of evacuees involved in the battle. Unable to perform advantageous operations.
Taking advantage of this machine, the Chinese army swallowed special forces into the refugees in small units and disturbed the rear. For this reason, operations and pinpoint attacks that mobilized the amount of strength that the U.S. army is good at have failed, and due to guerrilla warfare, the U.S. military has suffered damage that has never been experienced in recent years, and morale has greatly decreased. It was.
The US military has been considering the use of suppression weapons such as vaporization bombs that can destroy a wide area at once, but the Chinese side said, “The power of mass destruction weapons such as vaporization bombs is tactical. Declared to use nuclear weapons.
For these reasons, the US and Korean troops continued to recede and were being driven to the southeastern part of the Korean Peninsula.
The US and South Korea governments have reached this point, and have requested the Japanese government to assist the displaced people to escape from the sea, in addition to the supply activities behind them. In response to this, the Japanese government has decided to dispatch aircraft groups such as C130 transport aircraft and CH-47 transport helicopters and “Osumi” class assault landing ships for the transportation of displaced persons including Japanese nationals.
Also, it was decided to dispatch a combat unit including an escort fleet and support fighter planes, assuming that a certain amount of “defensive armed force” is necessary for rescue operations in battle.
The dispatch of ground troops was strongly controversial from the public opinion that "it means overseas dispatch and conflict resolution by armed forces and conflicts with the constitution." However, the pressure of both the United States and South Korea, and the reality that many displaced people are already overflowing at the southern tip of South Korea, said, “In order to provide humanitarian assistance, it is necessary to secure air and sea control rights and a transportation base. It justified the painful interpretation of “exercise of force for humanitarian assistance and does not conflict with the Constitution”, and as a result, moved the Japanese government and public opinion.

About maps

In addition to the US and Korean troops so far, the Japanese Self-Defense Force will finally appear in this scenario.
Contextually, the Chinese army is squeezing both US and Korean troops, and the main battlefield has moved to the southern tip of the Korean Peninsula. Busan port, one of the leading ports in Korea, is the source of the US, Korea and Japan. The resistance front is supported by Busan and Tsushima behind it.
In order to evacuate refugees safely, it is necessary to slow down the enemy's advancement speed. For this reason, air force and artillery need to hit air bases and logistics behind the enemy front rather than the front.
In addition, in order to transport refugees using helicopters and aircraft, it is absolutely necessary to secure the right of air control over the sky. From this point, the early occupation and destruction of enemy air bases is required.
Transport ships can only be loaded and unloaded from the port. It is a good idea to check the easy beaches.
Refugees are troublesome to keep moving without regard to their intention. When you rescue them, you should also be aware that they can only be recovered by using the [rescue] command by placing a transport unit next to the refugee unit.
In addition, the rescued refugees must be transported to Karatsu Port in Kyushu, where they are well away from the front line and safety is guaranteed. Since Tsushima and Sasebo have military bases and can be attack targets of the Chinese army, Karatsu Port is assumed here as a transportation target point.
