The group operation that Chuikov mentioned was actually guerrilla warfare.

These groups were able to make use of buildings, ruins, and other terrain more flexibly, sometimes attacking and sometimes defending, while others were responsible for sneak attacks, sniping lone German tanks or small infantry detachments, and then retreating, moving from sewers and tunnels to other defensive positions.

This is exactly what Qin Chuan is worried about...... In a way, the Germans were not afraid of the Soviets fighting a conventional war with them, because in any case, the Germans had more advantages over the Soviets in conventional warfare.

But if the Soviets fought unconventional warfare with the Germans, such as urban guerrilla warfare and close-quarters tactics, then that was when the Germans had a real headache.

The so-called "close tactics" actually mean that the principle of "the enemy advances and we retreat, and the enemy retreats and we are closer" always maintain a certain distance from the enemy, weakening the enemy's equipment such as aircraft, artillery, and tanks while depleting the enemy's vital forces.

This was realized by the Germans the next day.

There were basically no gunshots heard that night, and the Germans thought that the Soviets would stop doing this because they had been countered by the Germans in the infiltration war at night in the past few days, but they didn't expect that this was not the case......

At dawn the next day, gunfire suddenly rang out from the building that had been occupied by the Germans.

It turned out that the Soviets took advantage of the darkness to infiltrate the rear of the German army through the sewers and tunnels without making a noise, because they knew that it would be difficult to inflict many casualties on the enemy when they could not see the enemy in the night.

They only quietly occupied a few buildings that were easy to defend and difficult to attack, and when it was daybreak, they suddenly attacked.

The situation was similar at the front, the Germans pushed forward as usual to fight the Soviets in front of them for control, and found that they were basically not intercepted by fire when they advanced, and they even swaggered into the building without anyone shooting at them.

But this is where the trouble is, because no one shoots at the building, so the tank does not know where the enemy is, so even if it fires, it is aimless.

It wasn't until a group of Germans entered the building that gunfire erupted from inside the building...... The Soviets built sandbags inside the building against those who invaded the building.

The tank still can't fire, because it can't tell where the enemy is and where it's its own people from the outside, or even if it can, it can't avoid accidentally injuring its own people after firing.

As a result, the battle soon fell into a state of glue, with the enemy and us fighting room by room in the building, and then seizing floor by floor.

As the baker said, "We occupy the kitchen, but we have to fight the living room with the enemy, and sometimes we are separated by a wall from the enemy, and we can even hear their breathing!" ”

However, the 1st Infantry Regiment obviously had a great advantage in this regard, because they had MP43s in their hands, which had a short body, ammunition capacity, and much more power than pistols and submachine guns, making them very suitable for fighting in confined spaces, so even if this tactic was very abrasive, the First Infantry Regiment achieved good results.

But the Germans in other directions were not so lucky.

The infantry of the 6th Army was only a small or even not equipped with MP43s, they did not even have many MP40 submachine guns in their hands, and most of them had K98K in their hands...... This rifle is very inconvenient to fight in corridors, rooms full of furniture, and in front of and behind narrow doors, especially since the ammunition capacity is only 5 and the firing rate is super slow.

Of course, the Mosin Nagant rifle in the hands of the Soviets has a similar problem, but as mentioned before, the gap in equipment and casualty between us and the enemy is narrowing.

As a result, the Germans in other directions were basically advancing at a speed of meters, and they were covered with corpses and blood.

"Major!" On this day, when Qin Chuan and the soldiers were cleaning every corner of a newly occupied building, the signal soldier said to Qin Chuan: "Colonel Slain called, he asked you to go to the division headquarters!" ”

Qin Chuan nodded, explained Eberhard, and walked back with a guard squad...... Qin Chuan didn't dare to hold it up here, there might be Soviet soldiers lurking in every corner of every building, even in the German-controlled area, so no matter where you go, you must bring at least one squad of people.

The group got into the car and drove back, Qinchuan has a jeep, but another meaning of taking a jeep in this ghost place is to tell the Soviet snipers...... I'm an officer, shoot me!

Ten minutes away, the car stopped in front of the small house used as the division headquarters.

To be exact, the division headquarters was in the basement of a small house. Qin Chuan had been here before, and the furnishings were very simple, only a bench and an earthen table, and the focus was that there was a 12 to 15 feet thick layer of soil on the top, which could withstand the bombardment of small-caliber artillery fire.

To Qin Chuan's surprise, when he walked into the headquarters, he found that Major General Witsheim was also inside, and he was discussing something with Colonel Stryk and Slain at this time.

"Major!" When Major General Wiesheim saw Qin Chuan coming in, he warmly invited Qin Chuan to join the discussion.

"It turns out that the method you proposed before is effective, Major!" Major General Wiethesheim said: "We have made a lot of progress after using the 'lattice tactic'. But at the same time...... We also seem to have forced the Soviets to have to change their tactics! ”

"Yes, General!" Qin Chuan replied: "We feel this!" ”

Qin Chuan was fighting on the front line with his fighters, and of course he knew that the tactics of the Soviets had changed.

But Major General Wiesheim shook his head and said: "No, I don't think you feel it, maybe you don't feel it that deeply, because only the First Infantry Corps is still attacking, and the other troops are already struggling!" ”

"Because we have MP43!" Qin Chuan told the truth.

"I know, Major!" Major General Wiethesheim replied: "My soldiers are also equipped with some, and they all all respond to the desperate desire to have MP43s, but I contacted the arsenal in Berlin...... They are not produced enough to allow us to fully reequip in the short term, and on the other hand, there are problems with ammunition! ”

Of course, Qin Chuan can understand this, the high rate of fire of the MP43 means that more ammunition is needed.

If it is one regiment or two regiments, it is not a problem to equip MP43, but if it is popularized throughout the army...... This increased amount of ammunition is not something that the German army's current logistics in Stalingrad can support.

"Major!" General Stryk said to Qin Chuan bluntly: "In other words, we must find a way to deal with the tactics of the Soviets, I mean with the existing equipment conditions!" ”
