Back to the Republic of China to be a editor

The basic task of the 40th Army is to separate the 2nd Meibu Division from the South Korean troops. The extended task is to intersperse multiple routes to kill and injure its vital forces in the defense area of ​​the 2nd Meibu Division.The basic task is not difficult to complete, in fact, the 40th Army is a bit too aggressive.

Tang Hua saw the battle report of the 40th Army. On the evening of the 25th, the 40th Army broke through the frozen Qingchuan River in an environment of more than 20 degrees below zero, and inserted into the hinterland of the 2nd Meibu Division. In the first battle, it destroyed an artillery battalion of the US Army, captured 18 105mm howitzers, and then captured Yulongpu Forming a siege to the 2th Regiment of the 9nd Meibu Division.The 9th Regiment was shocked. On the 26th, the 118th Division cooperated with the 120th Regiment of the 359th Division to block and block. On the evening of the 26th, the 9th Regiment not only failed to break through, but lost more than a dozen tanks, and the encirclement was also compressed. up.

Looking at this posture, the 2nd Meibu division will lose a regiment in place.If this is the case, what should the Meibu 2nd Division do in Longyuanli-Anzhou when the general retreats later?Can you stand out?

In the prisoner-of-war camp, is it necessary to arrange in advance the cell of the commander of the 2nd Mibu Division?

……

Junyuli, the headquarters of the U.S. Ninth Army.

"Those Koreans were rushing all the way west and refused to respond to the radio call signs, so our troops had every reason to think they were hostile forces and it was reasonable to open fire on them!"

Brigadier General Tahsin Yazić, head of the Turkish brigade, defended himself at the headquarters.

"As far as I know, the South Korean 7th Division did call on the walkie-talkie." William Hodge, commander of the 9th Army, frowned.

This oolong made a lot of trouble.

The two battalions of the Turkish brigade quickly surrounded and wiped out the "Chinese army" that was advancing from east to west. After the battle, more than 100 bodies with oriental faces lay on the ground, and the Turkish brigade also captured about 200 people.It was only when the prisoners were interrogated that something was wrong.

"The Turks are lying, we radioed the troops ahead to prepare to respond!" Shin Sang-chul, who was first captured and then released, said angrily.

"My battalion has only English translators and no Korean translators. Therefore, the poor communication between the forward infantry battalion and the Koreans is a technical problem that has been neglected. Neither I nor my battalion commander should be held responsible." Yaziqi spread his hands, "This is the defense zone of the 9th Army, not the defense zone of the Korean Second Army, which is why General Hodge did not equip my troops with Korean interpreters. Moreover, your division should be in Hee You should not have fled to the west when you fought in Sichuan. But it did happen: you broke away from your position and fled to the west without authorization. If you want to use the law to solve the problem, please, should I go to the military court or do it without authorization You who escaped?"

The quarrel meeting at the Ninth Army Headquarters lasted until the morning of the 9th. The Ninth Army and the Korean Second Army reported their reasons to the United Nations Command. At the time of the lawsuit, Turkish military reporters had already The report was written and sent back to China.The first victory of the Turkish brigade expedition to North Korea!Annihilated hundreds of Chinese troops with minor casualties, and captured more than 27 prisoners alone!This is a beautiful victory!

……

Jiaohe, 50 Center.

While assisting the intelligence staff center to analyze the enemy's situation, he also basically figured out a clue to the cracking of the US military-level code.

Tang Hua and Wang Yongjun first determined that the use of M-209 superimposed one-time pad encryption by the US military could be ruled out.

One-time pad, also known as Vernan-style encryption, in terms of terminology, one-time pad means that the length of the key used to encrypt a message is not less than the length of the message.

For example, Obama and his younger brother parted ways in Guangzhou. Before leaving, they agreed that they would use the 82 edition of "Water Margin" published by the Commercial Press in the future. ) key.To the uninitiated, they were encrypting with a true random number sequence.

This can't be cracked, even on a computer.

However, although the one-time pad is technically absolutely safe, it is also relatively cumbersome to use.Encryption and decryption are very slow, and when used in the military, there will be a timeliness problem, and it is easy to miss fighter opportunities.The error rate of one-time pad is very high. If there is an error in the reception, the two parties agree to return to the original point, which will easily expose the clues.In addition, in the computer age, information is not a telegram of dozens of words a day, but a massive amount of information counting in megabytes per second. A book of Outlaws of the Marsh can be used up in a few seconds, and has no practical value.

Another problem with the one-time pad is that it is technically perfectly secure, but not so technically secure.Both of them must have a copy of "Water Margin" with them, and Michelle will suspect that Obama is secretly playing tricks. Michelle may buy the same "Water Margin" from the bookstore, and Obama will be finished.It is not safe for Obama to hide "Water Margin" among the hundreds of books in the bookcase, because "Water Margin" is used to send and receive telegrams every now and then, so the cover of this book must be fluffed.Why are all the other books on the Internet brand new, but "Water Margin" is broken?Obama is done again.

Coupled with the intuitive study and judgment of the ciphertext, Tang Hua and Wang Yongjun affirmed that the military-grade cipher of the US military is formed by combining M-209 with another encryption method.

Soon the two formulated a cracking plan, and explored in four directions.

It takes more than a day to calculate each direction, but the TC50 computer usage rate is not high now. The U.S. military has not changed the key for a while, so TC50 has a lot of time to calculate and crack.

Wang Yongjun commanded four operators to start the TC4 excitedly, but Tang Hua was not so excited.

After several hours of calculation in the first section, Tang Hua left the supercomputing room and walked out along the wide and empty underground passage.There have been two heavy snowfalls in Jilin in the winter, but the entrance to the 50 Center is very clean, and the snow ruts caused by the vehicles entering and exiting are immediately cleaned by the orderly staff after the vehicles pass by.

Tonight, the 9th Corps on the Eastern Front is about to launch a full-line counterattack.

The 7 branches of China Resources in Dalian worked hard overtime, equipped the 9th Corps with complete winter clothes, winter marching supplies, and distributed compressed biscuits for a week.Compared with the situation of wearing winter clothes in the Yangtze River Delta in history, the current 9th Corps should no longer be frozen.In the second battle, 9 soldiers of the 2.9th Corps were frostbitten. As for the large number of frostbite, the entire regiment and battalion could not continue to fight, which led to more combat casualties among neighboring troops, so it is impossible to count.

But is winter clothing the answer to all your problems?

No.

This is what Tang Hua has been worrying about these days.

To face off against the 9st Marine Division, the [-]th Corps lacked not only winter clothes, but also heavy firepower.

The first batch of the 13th Corps to enter the DPRK, and the 50th and 66th armies that joined later were on the western front, because the Northeast Frontier Army has been making various preparations for entering the DPRK. Generally speaking, the equipment is relatively complete. Now we are on the western front. In addition to the 6 infantry corps, 3 artillery divisions also entered the DPRK to participate in the war.

Although it is incomparable with the American artillery, our artillery division is only the Japanese-made Type 90 75mm field artillery and the American-made 105mm howitzer. If it is bombarded with the 105mm and 155mm American artillery, it will suffer a lot.But after all, it is also an artillery with a range of more than ten kilometers. Its tactics are a little bit different, and it does not contradict the US artillery. It can still play a great role in supporting infantry to attack fortified positions and mobile warfare.

What about the 9 Corps?Of the three armies that entered the DPRK, there was no artillery division. No matter how bad the 90 field is, it is better than nothing. Without long-range artillery suppression, this battle will not be easy to fight.

One is the rush of time, and the other is that there are not many artillery divisions in the country.

The total artillery firepower of the 9th Corps is three army artillery regiments, each artillery regiment has three 75mm light howitzer battalions and one 108mm rocket launcher battalion.The rest are the 75mm mountain artillery and 70mm infantry artillery under the jurisdiction of the infantry division.Tang Hua was also reading telegrams these days. During the march in the snow, the 9th Corps was forced to discard a lot of mountain artillery and infantry artillery because a large number of mules and horses froze to death.

In other words, there are now 9 people in ten divisions of the 12th Corps, and there is not a single gun with a diameter greater than 100mm.

And the U.S. military on the opposite side is simply a monstrous existence.There are 105mm howitzers under the regiment and 155mm howitzers under the division. There are more than 5000 people in the first marine division marching northward in a group. There are three regiments and three battalions. One of the regiments is an artillery regiment. .

Fully dressed and poking his back with a snow pole, Tang Hua tried to ski on a relatively gentle piece of snow in the woodland outside the 50 center.

The more I think about it, the more I catch chickens, but I can't stop the various thoughts in my mind.

The 5000-strong detachment of the 3st Marine Division is nothing. Tang Hua knew that after the 2.5rd Meibu Division reached Xingnan Port, Smith, the commander of the 7st Marine Division, personally led the remaining Marine Regiment plus a tank battalion. The three logistics support battalions also set off northward together to support the two regiments in front.In the end, there were as many as 3 troops of the First Marine Division in the Changjin Lake area, and more than [-] troops with the [-]th Meibu Division.

With 9 soldiers in the 12th Corps and about 10 fighting on the front line, what can they do against the 3 U.S. troops?

Chapter 89, Fighting in Hell

Changjin Lake, heavy snow.

On November 11, at 27 pm, the temperature was minus 3 degrees.

The vanguard of the first regiment of the first marine division arrived in Xiajieyuli.

Although repeated orders were made to let the Fifth Marine Regiment and the Seventh Marine Regiment, which set off first, advance in groups and not to separate, Division Commander Smith was still worried.When a regiment of the 3rd Meibu Division arrived in Xingnan and the port defense was guaranteed, Smith set off with the remaining regiment of the 9st Marine Division.In addition to the first marine regiment, this reinforcement also includes a tank battalion, a reconnaissance battalion, and three logistics support battalions, with a total number of more than [-] people.

The eastern and western fronts of the second campaign were isolated from each other—between the east and west lines was the towering Taibai Mountains, which were difficult for ground troops to cross.This made Smith feel even more uneasy. The 10th Army and the 8th Army had to fight independently.The 7th Meibu Division and the 7st Marine Division were responsible for the offensive on the eastern front. Smith felt that the commander of the 17th Meibu Division must have taken the wrong medicine. The lake turns to the northeast, and soon disappeared. Now the 32th regiment is in Huishan Town on the border between China and North Korea. Almond and Badawi just finished taking a group photo by the Yalu River. The 17nd regiment is in Jiashan, not far from Huishan Town. .Both regiments are more than 32 kilometers away from the First Marine Division. If something happens, they will not come back to support the First Marine Division.

Now only the 7st Regiment of the 31th Meibu Division is near the [-]st Marine Division.

Xiajieyuli is a small town in Changjin Hunan. During the Japanese occupation period, due to the relationship between forestry and power generation, this area was relatively developed. Japan not only built roads here, but also built a small airport.After the First Marine Division took control of Xiajieyuli, the engineering unit quickly repaired the airport.

The 5th Marine Regiment and the 7th Marine Regiment are located in Xixingling, west of Changjin Lake, about 15 kilometers away from Xiajieyuli.

The troops of the First Marine Regiment guarded Xiajieyuli, Fushengli, and Gutuli respectively, arranged linearly in a north-south direction, with the division headquarters in the northernmost Jieyuli.The task of the 5st Marine Regiment is to defend the road from Xingnam-Hamhung-Changjin Lake, and protect the buttocks of the 7th and 5th regiments, so that when the situation is not good, the 7th and [-]th regiments can easily slip back .

As for the 7st Regiment of the 31th Division of the US Army, as the commander of the Marine Division, Smith can't control the Army's troops at all, so let him go.

Almond had long ago ordered the [-]st Marine Division to attack westward, cutting off the highway between Jiangjie and Xichuan, which was one of the two supply lines through which the Volunteers obtained supplies from the country.

Another supply route for the Volunteers is the passage from Andong to Sinuiju.Since November 11th, the U.S. military has intensively bombed this area. Now the United Nations Army believes that the Andong-Sinuiju supply line should have been bombed.

On November 11, the 27st Marine Division finally moved. The 5th and 7th Regiments marched northwest from Xixingling. First, they sent a reconnaissance battalion to step on the spot, and then the 7th Regiment moved 5 kilometers northwest and entered Liutanli.Then the 5th regiment also began to move to Liutanli.After entering Liutanli, the 5th and 7th regiments were 20 kilometers away from Xiajieyuli.

In the mountains and forests southwest of Changjin Lake, the 9th Division of the 20th Army of the 58th Corps quietly moved to the starting position for the attack.
