"It is reported that the armored train has completed assembly preparations at the predetermined position and is ready for battle. ”

"It is reported that the self-propelled 200 mm caliber * gun vehicle has completed assembly and preparation at position No. 1 and is ready for battle. ”

"It is reported that the 155 mm caliber vehicle towed * artillery regiment has entered position No. 1, and it is expected that in 20 minutes, assembly preparations will be completed. ”

"It was reported that the units had entered their predetermined positions, completed their preparations and were ready to fight. ”

"The report said that the routine reconnaissance 1 hour before the drone battle ended, and the Japanese army's position and troop layout did not change. ”

Qiu Yahui nodded, looked at his watch, now there are about 30 minutes before 12 o'clock, and in front of him, there is a huge Liaohe River valley topographic sand table, as the herald reports the movements of various troops, some staff officers will represent the different branches of the enemy and the enemy, weapons small models on the sand table, on the large display boards set up on both sides of the sand table, there are also people in chronological order, paste the report information on the display board.

At present, the People's Army and the Japanese army are roughly separated by the Liao River, starting from Xinmin County and facing each other in the area of six rooms, and the entire front is about 120 kilometers long.

The Liao River is an important river in Northeast China, but unlike other rivers, such as the Yangtze River and the Yellow River, which have clear upper, middle and lower reaches and are clearly distinguished from the main stream and tributaries, the Liao River is a collective name for a combination of multiple river systems. There are two sources of the Liao River, the West Liao River and the East Liao River, the two sources converge in Fudedian, Changtu County, Liaoning Province, and are called the Liao River. It is divided into two strands near the six rooms in Panshan County, one goes west, flows into the Bohai Sea after the Yang River in Panshan County, this section is also called the Shuangtaizi River, the Liao River is generally said, it actually refers to this section; one goes south, called the Wai Liao River, and is called the Da Liao River after the confluence of the Sancha River and the Hunhe River and the Taizi River, and enters the Bohai Sea in the old border area of Yingkou City, in 1958 in the old time and space, the Wai Liao River is cut off in the six rooms, and the Da Liao River has become an independent water system. The surface of the Liao River is not wide, generally between 100-300 meters, and the water depth is 2-6 meters, while the water surface width of a few sections will exceed 500 meters, and the depth reaches 6-9 meters.

At this time, Japan invested more than 400,000 troops in the Liaodong battlefield, roughly about 240,000 on the Shenyang line, about 75,000 on the Liaodong line, about 50,000 troops in Liaoyang, about 32,000 troops in Lushun, and about 80,000 troops in Korea, so Japan's total strength was about 500,000. However, this is only for the combatants, and there are about 700,000 logistical support personnel in the Liaodong region, and more than 1 million people in Japan who are working in support of the war effort.

The 4th Army Corps, commanded by General Michiki Nozu, was in charge of the defense line on the Liaohe River, and was under the command of the 5th and 10th Divisions, the 3rd, 10th, and 11th Reserve Brigades, the 1st Artillery Brigade, and the 2nd Reserve Brigade Engineer Battalion.

The division of the Japanese army is different from that of other countries, a division has two brigades, each brigade will have two regiments, and two special operations regiments, generally a cavalry regiment and an artillery regiment, and other auxiliary armies, so the average Japanese division has 15-20% more troops than the divisions of other countries.

However, in the face of a front of more than 120 kilometers, it is impossible for Japan to adopt the tactics of arming defense on all fronts, otherwise more than 70,000 people will be wiped out, so it can only use the core of the battle line to deploy troops. The Japanese army chose to take the three strongholds of Ping'an Fort, Liaozhong, and Shaling Fort as the core, and arranged the Liaohe defense line, because Ping'an Fort was relatively close to Shenyang, and the troops were the least arranged, which were the 3rd and 11th reserve brigades; Liaozhong was the middle of the entire defense line, and it was also likely to be from the main attack direction of the People's Army, so Nozu Michigui set up his headquarters in Liaozhong, and the troops were also the strongest, the 5th Division and the 10th Reserve Brigade; Shalingbao arranged the 10th Division, and the rest of the troops were scattered in these three garrisons.

After consulting with the personnel of the military headquarters, Qiu Yahui determined that the main direction of attack of the People's Army would be in the central Liaoning region, starting from Laodafang Town in the north and reaching Daniu Town in the south, with a total length of about 35 kilometers. The headquarters of the 2nd Army was located in Tai'an County, and the troops invested were the 2nd Division attacking from Daniu Town, the 8th Division attacking from Xinfatun, the 9th Division launching an attack from Laodafang Town, and the 17th Division and the reserve regiment as reserve forces.

The position of the armored train is in Xifo Town, which is about 7 kilometers away from the Liao River, and the armored train is equipped with a 240 mm caliber and 40 radial range of artillery that can reach 30 kilometers, and the firepower can cover the entire battlefield.

The self-propelled 200 mm gun truck* has a range of 23 km and has 3 positions on the battlefield, and a 155 mm car tows * The firing range of the artillery is 17 kilometers, and five positions are set up, which can ensure that the striking range of these two types of artillery can also cover the entire battlefield, and between each position, simple roads have been repaired, and the shells used in these two types of artillery do not move with the gun trucks, but are transported to each artillery position before the start of the war to wait, so that the battlefield mobility ability and ultra-long range of these two types of ace weapons built by the East China government can be fully played.

In this era, the firing range of the average 150 mm caliber * gun was generally about 9-12 km, and the firing range was much smaller than that of the 155 mm caliber car towing * manufactured by the East China government. This is mainly due to the fact that the army artillery of this era is difficult to move, so the diameter times are not too large, a section is between 20-25, and the maximum is not more than 30, if the diameter times are increased again, the overall weight of the artillery will be increased, thereby further increasing the weight of the artillery, only 88 mm, 100 millimeters of artillery can reach 35-40 times, but because the caliber of these guns is too small, even if the diameter is increased, the firing range can only be increased to about 10 kilometers.

The 240 mm caliber armored train gun built by the East China government, the diameter multiple of the self-propelled 200 mm caliber * gun 155, and the millimeter caliber car towed * gun have reached 40, and such a diameter multiple can generally only be achieved by naval naval guns or coastal defense guns, after all, naval naval guns have a huge mobile platform of warships. However, the East China government has solved the problem of artillery movement, and it is natural that the naval guns can be directly moved to the army, and they can also maintain a strong battlefield mobile capability, so this is the main reason why the East China government regards it as a trump card, otherwise 240 mm and 200 mm caliber artillery will be counted, and 155 mm caliber artillery is considered a large-caliber artillery in the army, but it is not uncommon, why can it also be called a trump card?

Of course, on warships, the effective range of naval guns is much smaller than their maximum firing range, for example, 240 mm caliber naval guns can hit 30 kilometers, but the effective range is actually less than 10 kilometers, or even 7 kilometers, this is because the navy needs accurate shooting, Bi Jing's warship is more than 100 meters long at most, but for the army, it is not a problem at all, how big a position is, even if it is a few hundred meters away, 1 kilometer is not a serious matter.

Due to the ultra-long range, these three ace weapons can attack outside the enemy's firepower, so they do not need to carry a large number of shells to move, but to send the shells to the set position in advance, and can only be used by artillery.

Although he knew that the Japanese army was focusing on defending the middle section, he still decided to take the middle section as his main direction of advance, and it was precisely these three ace weapons as his confidence.

At 11:50, Qiu Yahui ordered to take off the helicopter to observe the landing point of the shells in the air, provide firing parameters for the artillery, and ordered each artillery to adjust the firing unit and prepare to fire.

These three ace guns manufactured by the East China government are all for line-of-sight shooting, commonly known as blind shooting, or map shooting, which not only requires an accurate battlefield map, but also needs someone to observe the landing point of the shell, so as to provide parameters to trim the firing unit of the artillery, but these two points, from the latter point, is quite difficult in this era, even if it is possible to arrange soldiers to lurk near the enemy's position and observe the landing point of the shell, but how to transmit the shooting parameters back? Therefore, this is also one of the thresholds that limit the expansion of the range of artillery.

In the old time and space, it was during the First World War that these two major problems were solved, by the popularization of trains, the development of automobiles, so that the difficulty of artillery movement was reduced, and the development of airplanes and radios solved the problem of artillery landing point observation, so during the First World War, a variety of large-caliber, ultra-long-distance artillery also appeared in large numbers, but at that time, the level of trench warfare was greatly improved, and it also successfully offset the advantage of increasing the range of artillery.

However, these two major problems are not a problem for the current KPA now, UAVs and helicopters are all ways to solve the problem of observing the landing point of artillery shells, so that the KPA can take a step ahead and gain the advantage of firepower outside the line-of-sight.

At 12 o'clock, Qiu Yahui gave an order in the headquarters of Tai'an: "Open fire!"

The first gun started with the armored train guns, at this time the two train guns had adjusted their firing units, at this time the two train guns were decoupled from the other carriages, leaving a distance of about 500 meters, and the two train guns were also about 200 meters apart, and put down 8 thick support columns, the end of which was buried more than 1 meter deep in the ground, and the soldiers also retreated to 100 meters away, and all brought earplugs, only two wires connected to the two train guns that seemed a little lonely.

Of course, 1,000 meters away from the perimeter, the armies of the two companies to which the armored train belonged had already made a guard arrangement, and although it was on their own territory, these guard work could not be sloppy.

Having received the order from the command, the gun commander immediately ordered: "Gun No. 1, shoot." ”

The launcher pressed down the lever of his hand hard, only to hear a loud "boom", and the thick muzzle of the cannon sprayed dazzling firelight, although it was more than 100 meters away, but the soldiers still felt the earth shake.

It takes about 30-40 seconds for the shell to fly, so this time can only wait. About 1 minute later, the gun commander received a notification from the command: the landing point was accurate, there was no need to adjust, and 10 rounds were fired in a row.
