The military landing in Yuanshan was a major turning point in the early stage of the Peninsula War.

Compared with the Incheon landings in the Korean War in the 1950s, although they were amphibious landings carried out behind enemy lines, the difference between the two is very obvious.

In order to land in Incheon, the US military made a lot of preparations and used the hours of high tide to send the troops ashore.

Yuanshan landing was very "simple", and amphibious landing became "three-amphimosis" landing, with the main projection force changing from landing craft to helicopter, and the main support force changing from ships to fighter aircraft. The biggest change at the tactical level is that the pace is significantly accelerated, and the offensive speed is far exceeding that of amphibious landing operations in the era of mechanization.

The Korean army could not adapt to the speed of the US offensive.

The war had just broken out 24 to 10 hours ago, and many Korean troops did not even prepare for the war. The Korean troops participating in the war were still resisting the attack from the south, and the US military opened a second battlefield behind the front line.

The high-intensity bombing that lasted for several hours completely defeated the Yuanshan defenders' will to resist.

According to statistics from the US military, during the bombing, at least half of the officers and soldiers of the three North Korean military advisors stationed in Yuanshan fled at the last minute, with more than 15,000 deserters, and even the entire battalion of officers and soldiers fled north at the same time.

The escape became the beginning of defeat.

Before the bombing was over, the US drone that took off from the amphibious assault ship arrived over the battlefield and began to guide the targets for the "Zumwalter" class destroyers in the amphibious fleet.

During the Iran War, the "Zumwalter" class destroyer performed bravely. The combat effectiveness of 155mm naval guns was confirmed.

Against the backdrop of the "China-US Cold War", the US Congress not only approved the procurement of more "Zumwalt-class destroyers", but also asked the Pentagon to formulate a "Navy Long-term Development Plan". It clearly mentioned that in addition to reducing the number of "Free"-class coastal warships, the Navy will purchase "Zumwalt-class destroyers at a rate of three lands per year, and replace all "Alik-class destroyers by 2035. Based on the "Zumwalt-class" hull, a comprehensive replacement of the "Ticonderoga"-class air defense cruiser will be developed.

Before the outbreak of the Peninsula War, the US military had a total of 24~Zumwalter-class destroyers (6 of which are under construction). In addition to equipping one for each aircraft carrier battle group, it also equipped one for each of the six amphibious fleets.

The most obvious thing about the "Zumwalter" class destroyer is its super ground-to-ground strike capability.

When using EGMSS (rocket boosted extended range shells), it can strike all ground targets within 1c0 nautical miles (about 185 kilometers) range; when using EDD (ultra-long-range attack shells), it can strike all targets within 150 nautical miles (about 277 kilometers) range; starting from the 22nd (under construction), it will be equipped with a 155mm electromagnetic gun (the US military has planned to improve one of the previous construction ships according to the same standard). This will enable it to strike all ground targets within 200 nautical miles (about 370 meters) range; if it is used to deal with inland targets, it will use a hypersonic cruise missile with a range of 1km or a 25c0 kilometers range of 25km.

Generally speaking, the "Zumwalter" class mainly uses long-range shells to attack ground targets.

First, shells are cheaper. Even the most expensive edd, the unit price is less than 50,000 US dollars, while a cruise missile costs at least 5 million US dollars (2 years of currency), which is only one percent of the cruise missile; second, naval guns react faster in combat operations, and only 5 minutes from receiving orders to reaching artillery support, while missiles take 1c to half an hour; third, ammunition reserves are more sufficient, and each "Zumwalter" class destroyer can carry 1155mm shells, but can only carry the most.

80 more (actually far from reaching, because 80 vertical launchers must be equipped with some air defense missiles, anti-ship missiles and anti-submarine rocket-boosted torpedoes) ground attack missiles; fourth, the continuous combat capability of the naval guns is significantly greater than that of the ground attack cruise missiles. The 155mm electric heater can fire for several hours at a speed of 6 per minute, or fire rapidly for 5 minutes at a speed of 12 per minute. No ground attack cruise missile on any warship can continue to attack targets on the shore at such a fast speed.

During the Iran War, the three Zumwalter-class destroyers participating in the war used less than one percent of their investment to destroy 80% of the ground targets in coastal areas, and the combat efficiency ratio was far greater than that of any other warship.

During the Yuanshan landing battle, the US military deployed two "Zumwalter" class destroyers.

Before the landing troops landed ashore, the 2 "Zumwalter" class destroyers, guided by unmanned aircraft, shot nearly 1,700 shells to hundreds of targets on the shore, with a hit rate of more than 8 and a destruction rate of nearly 60%. The combat effectiveness was amazing.

High-intensity artillery bombardment destroyed the last line of defense of the Korean army.

The US Marines boarded a helicopter entered Yuanshan without any resistance and quickly controlled the roads to the port and the airport.

At 2 o'clock, the Marine Corps controlled Yuanshan Airport.

A few minutes later, the first batch of troops of the 1st Air Assault Division arrived and joined the combat operation to attack Yuansan Port. At this time, another batch of troops from the 1st Air Assault Division, which arrived at the Japanese Air Force Base in the afternoon, set off for South Korea, and then replenished fuel in the middle and flew directly to Wonsan Airport.

Before, the US military entered Yuanshan Port.

Nearly 2,000 soldiers and soldiers trapped in the port fought desperately and blew up the port

Most infrastructure.

The US military probably did not rush to enter Yuanshan Port in order to avoid excessive casualties.

By this time, the Korean army stationed near Yuanshan had completely retreated.

However, the US military did not expect that just a few hours later, the Korean army blew up Yuanshan Port into ruins, leaving behind an uncontrollable mess.

For the combat operations in the future, the Korean army guarding Yuanshan Port made the greatest "contribution".

According to the plan, after the US military occupied Wonsan Port, it will immediately send heavy equipment from the amphibious fleet to ashore and then launch an attack on Pyongyang and Ham Hing. Because the port infrastructure was blown up by the North Korean army, the US military was unable to send a large amount of heavy equipment to ashore immediately, and it was impossible to launch a ground attack immediately.

In desperation, the US military had to adjust its tactical arrangements.

The 1c11 Air Assault Division, which originally cooperated with the 2nd Marine Division, became the main force of the offensive, divided into two routes, attacking Pyongyang and Hamhung, occupying the transportation hubs and military centers along the way.

Support for the 1st Air Assault Division were carrier-based aircraft in the three aircraft carrier combat groups entering the Sea of ​​Japan.

In order to reduce the difficulty of the attack of the 011th Air Assault Division, the US military dispatched 12b strategic bombers in the early morning and fired hundreds of air-launched cruise missiles at the plateau north of Yuanshan (the name of the town, located at the intersection of Yuanxian Railway and Pingyuan Railway, the transportation hub center and the military center) to the military camp, air defense position and command communication center. Then nearly 30b-1bb bombers were dispatched to volley the North Korean defensive positions and dropped hundreds of tons of bombs!

The US military dared to use strategic bombers to conduct volleyball bombing, one was that it had fully grasped air supremacy, and the other was that there was no threat of air defense.

These two large-scale bombings completely collapsed the Korean infantry division stationed on the plateau!

When the assault troops of the 1st Air Assault Division arrived at the plateau, they captured thousands of Korean soldiers with blurred consciousness and completely collapsed. Many of these captured Korean soldiers returned to North Korea after the war.

According to some people's recollections, the "carpet bombing" of the US military not only destroyed the defensive positions of the North Korean army, but also destroyed the will of the North Korean army to resist.

According to relevant records of the 1st Air Assault Division, a total of 3,700 ~ corpses of North Korean soldiers were buried on the plateau!

After bombing the plateau, the US military dispatched strategic bombers again to carry out large-scale strategic bombings on Xinchengchuan, northeast of Pyongyang.

But the US military did not continue to have good luck. During this round of bombing, a b-1b was shot down by the North Korean air defense missile!

Although only one bomber was lost, the US military still quickly adjusted its tactics and did not allow the strategic bomber such as b-1b, which is about to be retired, to carry out large-scale bombing missions with ordinary bombs. b-1b is not a b-2, and the risk of using guided bombs to perform attack missions is very high. Apart from ordinary bombs, the best choice is air-launched cruise missiles.

The problem is that at that time, the US military did not have many air-launched cruise missiles.

Fortunately, the US military has sent a large number of tactical fighter jets to Japan at this time. Even if the B-1b cannot participate in the war, it will have a great impact on the air strike.

Due to lack of heavy equipment, the 1st Marine Division had not arrived yet, so the US Marine Corps landing in Yuanshan did not dispatch.

The US military successfully landed in Yuanshan, but failed to advance quickly as planned.

If you drag on it, the US military will not get any benefits.

In order to solve the problem, the South Korean and American coalition forces temporarily changed their combat plan. The US Marines arrived at Wonsan first advanced towards the south (town place name) to assist the South Korean army and the US 7th Infantry Division in the south annihilate the North Korean army in Gangwon-do, so that the South Korean army and the 7th Infantry Division could quickly move north and replace the Marines to launch an attack on Pyongyang.

If only the US military is carrying out the mission, the problem is not very big.

The problem is that the US military must cooperate with the South Korean army, and the main force is the South Korean army, not the US military.

The US military quickly adjusted its combat plan, but the South Korean army was unable to adjust its combat plan immediately.

On the morning of the 20th, the 7th Infantry Division occupied Jinhuadi and advanced towards Huaiyang. When performing the interweaving and division tasks of the battle, the Korean army accompanied the 7th Infantry Division did not follow immediately, but stayed in Jinhua. After the Korean army set off, they did not follow the 7th Infantry Division to advance towards Huaiyang, but instead attacked Changdao to the east according to the original plan and advanced towards Gaochenggang, the destination!

The supporting character rushed to the front and the protagonist lost his way.

To make matters worse, after the US and South Korean troops split up their routes, nearly 50,000 Korean troops surrounded Changdao-Huachuanli-Huaiyang!

In an area less than 1 square kilometer, 50,000 Korean troops gathered!

Not to mention 50,000 soldiers, even 50,000 civilians rushed out at once, and the flanks of the South Korean and American coalition forces would be threatened.

Fortunately, the US commander discovered the "mistake" action of the South Korean army in time, and then concentrated air forces to strike the North Korean army in an attempt to break through, causing the South Korean army to turn immediately.

It is obviously too late to adjust the offensive direction at this time.

The South Korean and American coalition forces had to adjust their combat plans again and first annihilate the 50,000 besieged Korean troops.

Obviously, the Korean and American coalition forces did not go smoothly in Gangwon Dok, but compared to the battle in Kaesong direction, this little trouble is nothing.
