Just when the logistics convoy arrived in the Dalinor Lake area, the armored motorcycle unit attacking Kulun finally set off from Chifeng.

The assault force consisted entirely of tanks and armored vehicles, with a total of 92 tanks, 52 armored personnel carriers, 24 communications command vehicles, 54 shop vehicles, 20 trucks, and 3 warrior vehicles. A total of 241 vehicles of various types, more than 3,000 personnel, including about 1,200 combat personnel, more than 900 vehicle drivers, more than 700 maintenance personnel, and more than 200 other technical personnel.

Even in modern society, the size of such an armored force is not small. Commander Chen Jingang was also very excited, he could finally command the armored forces to fight, although the first battle of the armored forces had been won by Wei Li, but he was the first commander of the armored forces, and he was also the first commander to command the armored forces to carry out long-distance raids, just by virtue of this, it was enough to be recorded in history.

Of course, Chen Jingang was not only excited, but also a little nervous, first, it was the first time he was in charge of the army, commanding the army to fight, and he was also commanding the armored troops, so of course Chen Jingang was also a little lacking in confidence. Although he is indeed an armored soldier, but it is an amphibious armored unit belonging to the Marine Corps, although they are all equipped with combat vehicles, but there is still a big difference between the amphibious armored force and the army armored force, Bijing amphibious armored force is used to provide firepower and armor force for beach battlefield landing, and the army armored force is responsible for the main land battlefield offensive operations. Second, this operation is a long-distance rush operation, and even in modern society, a long-distance run operation is one of the most difficult combat modes, in which there are many variables and unpredictable events, and if it is not done well, it will be a fiasco, and there is a great probability that the entire army will be annihilated. Of course, the definition of long-distance travel in modern society is also very different from this era, and the distance of more than 1,200 kilometers from Chifeng to Kulun cannot be regarded as a long distance at all.

However, whether it is excited or nervous, Chen Jingang cannot turn back, so after completing all the preparations, Chen Jingang also led the armored motorized troops from Chifeng without hesitation, unfolding the curtain of this long-distance attack, and also betting on his future development prospects.

Because all of them are motorized troops, despite the implementation of the system of driving for 3-4 hours and resting for 20-30 minutes, on the first day, the troops traveled for more than 12 hours, the effective driving time exceeded 10 hours, the average driving speed reached 27 kilometers, and a total of more than 280 kilometers were traveled throughout the day, in this era, this can be regarded as a miracle, of course, this day's march was not flawless, during the driving, a total of 9 cars had various problems, fortunately, the maintenance personnel worked very effectively, and the fault of these cars was not big, it was repaired quickly, and there was no delay in the marching time。

During the night break, the maintenance personnel worked very hard, checked all the vehicles overnight, and eliminated more than 50 small faults.

The next day, the speed of the troops' march slowed down, but it also traveled more than 250 kilometers, the effective driving time also reached more than 9 hours, and the average speed also reached more than 26 kilometers per hour, which is also very impressive, and in this day, 12 more vehicles had problems, but it did not cause much impact, and in two days, the total distance traveled exceeded 500 kilometers, and about 2/5 of the distance of the run was completed.

But on the third day, there was trouble, because it rained, and the grass was soon muddy, which caused great difficulties to the driving of the armored forces, only the tank was tracked, and it was not greatly affected, while the other vehicles were more or less troublesome, as a result, on this day, a total of more than 60 vehicles appeared to trap wheels and skid, and the failure ratio also skyrocketed to 21 cases, including two trucks whose engines exploded and were completely destroyed, and one armored personnel carrier, Three of the buggies were also badly damaged and in need of major repairs, which were obviously impossible to repair in a short period of time.

However, before leaving, Chen Jingang also expected this situation, although it was strictly tested and adjusted at the time of leaving the factory and in training, and a large number of support plans were made, but subject to the technical level of this era, it was completely destroyed, and the probability of major failures was very large, in fact, it only appeared on the third day, which has exceeded Chen Jingang's expectations.

And for the completely destroyed, major failure of the vehicle, can only give up, soldiers, materials are transferred to other vehicles, leaving only the driving team and maintenance personnel, fortunately in this problem of these vehicles are not far apart, so it took some effort to gather them together, and left enough maintenance tools, weapons and ammunition and 15 days of food, and reported their location to Chifeng, even if it can not be repaired, but it is enough to wait for the arrival of rescue.

Of course, there is a certain risk of leaving these cars and people here, after all, it takes about 5-7 days for rescuers to come from Chifeng, and during this time, if you encounter the Mongolian army, or the steppe wolves, it is very dangerous, but the war itself is a high-risk thing, so if you encounter it, you can only blame your bad luck.

But such a toss, although the driving time of this day also reached more than 11 hours, but the effective driving time is less than 8 hours, and due to the difficulty of driving caused by heavy rain, the speed can only reach a little more than 20 kilometers per hour, so this day only drove less than 160 kilometers, compared with the previous two days, far from the difference, but also an unpredictable factor in the long-distance run.

The situation on the 4th day did not get better, and the rain was heavier, so although last night, the maintenance personnel carried out anti-skid measures for the vehicle, not only replaced all the vehicles with rain tires, but also wrapped the tires with iron chains, but this day only drove out for less than 5 hours, and there were 5 vehicles damaged, Chen Jingang saw this, had to order the troops to stop the march, simply stop and rest, waiting for the rain to stop, and this day even 100 kilometers did not go, but due to sufficient time, 5 damaged vehicles to 3 were repaired, which is good news。

Day 5 finally ushered in a turnaround, the rain began to lighten, and at noon, there was a pause, and then it was also a stop, but it was much better than the previous two days, so at 12 noon, the team set off again, leaving only 2 vehicles that could not be repaired.

The convoy drove until more than 7 p.m., with only a 20-minute break, and because of the precautionary measures for the wheels the day before yesterday, not only did there no slip of the tires, but the speed of the drive was also increased, reaching a speed of 22 kilometers per hour, a total of more than 150 kilometers on this day, which is also a good result.

And on the 6th day, the weather finally cleared again, although the road was still muddy, but the wheels were prevented, and it did not have much impact, so the speed of the troops accelerated a lot, and this day drove for another 11 hours, and the effective driving time was more than 9 hours, the average speed reached 23 kilometers per hour, and a total of about 220 kilometers were driven throughout the day, but on this day 4 vehicles were damaged, and they were broken in two different places.

By this time, however, the KPA had covered more than 1,150 kilometres, and it was about 200 kilometres away from Kulen, which was about 100 kilometres longer because the assault force had to take a detour. According to the marching plan, the assault force should first reach a mountainous area about 40 kilometers away from Kulen for repair, and use this place as a temporary outpost to attack Kulen, but the actual journey tomorrow is only about 160 kilometers, so it can be said that this long-distance raid is already in sight.

It was only at this time that Chen Jingang's heart was a little relieved, after all, he had already passed 9 levels out of ten, and only the last level was left. Of course, by this time, the whole army was already very tired, and it had been raining heavily for two days, so even when they were camping at night, the soldiers could not put up their tents to sleep and rest, so they could only shrink into their cars to rest, and the effect of such a rest was naturally greatly reduced.

So Chen Jingang also decided to set off an hour late on the morning of the 7th day, so that the soldiers could rest for an extra hour, and although the weather was clear, the ground was still a little muddy, so only the chains on the tires were removed, but the rain tires were not replaced.

The troops set off again, because the driving pressure on this day was not great, so Chen Jingang also intended to suppress the speed, limiting the speed to about 22-23 kilometers per hour to ensure the state of the vehicle, but that's it, there were still three cars broken down on this day, but because they were about to reach the target at this time, Chen Jingang also decided to drag the broken three cars and march with the large army, so they drove for about 7 hours, and finally arrived at the first target of this long-distance run at about 4 o'clock in the afternoon.

The march took a total of seven days, ran more than 1,300 kilometers, and broke down 13 vehicles along the way, namely 1 tank, 2 armored personnel carriers, 2 communication command vehicles, 5 shop vehicles, and 3 trucks, of which 1 tank, 1 armored personnel carrier, and 1 shop aid vehicle were still towed to the target place, and there was still enough time to repair.

However, in view of the fact that the whole army was exhausted after a seven-day march, and at the same time, it was necessary to carry out a comprehensive overhaul of all vehicles, and it was also necessary to conduct necessary reconnaissance on Kulun, so Chen Jingang decided to rest the whole army for a day tomorrow to recover his mental and physical strength, and at the same time, he also asked the cooking personnel to cook a few good meals tomorrow to make full preparations for the battle of attacking Kulen.

Of course, technicians and maintenance personnel have to work a little harder, and they must overhaul all vehicles, at least combat vehicles, to eliminate hidden dangers and faults in the vehicles, and ensure that all combat vehicles can be in a better state to fight.
