It is said that when the Soviets returned to Stalingrad, they were stunned by the fact that the roads and railways had been completely emptied.

The Soviet army did not want to pursue it, and these sabotages alone were enough for the Soviet army to keep it busy for several months...... Landmines everywhere need to be removed, in fields, on roads and even in brick latrines.

The trouble is that these mines cannot be blown up with shells as in wartime, so they have to be removed manually, which is not only dangerous but also quite a lot of work.

Even more serious are roads and railways.

The highway is okay, the roadbed is damaged and repaired, the highway bridge is blown up and another one is built, and the potholes on the road surface are repaired, which is not very difficult.

The problem is the railway...... The sleepers were broken, the railroad tracks were demolished, and the tunnels and railway bridges were blown up, which made the Soviet troops want to cry without tears.

It is important to know that railways are an important means of logistics transportation in wartime, and trains can transport equipment and supplies to the front line in bulk.

But now...... If these railways were to be rebuilt, it would have to be from scratch, if not more so, because the tunnels had to be relocated, and because the metallurgical plant and other equipment in Stalingrad had been blown up, the Soviet Union had to produce even the rails somewhere else before transporting them.

And that's not all.

Winter is coming soon, and the Soviet military and civilians will have to restore these facilities in temperatures of tens of degrees below zero...... Because even if the battle line is pushed forward, the logistics and transportation cannot keep up, and the troops sent up are almost sent to death.

This is actually the benefit of fighting on someone else's land.

There is a saying that "destruction is easier than construction", destroying the railroad tracks is just hanging a barb behind the locomotive, and blowing up a tunnel is just loading a few packs of explosives.

And the Soviets wanted to rebuild them at a cost of tens, hundreds, or even thousands of times.

Worse still, this is Soviet land, and the Soviets can't do it if they don't rebuild.

In this respect, sabotage is actually the best tactic...... Historically, Mongolia used this tactic to drag down the economically strong Song Dynasty, and ran away after a while, and when the Song people were almost rebuilt, they came in to burn, kill, loot and withdraw, and it didn't take long for the Mongol cavalry to gallop around.

It's just that the Germans are not good at this kind of tactic.

Perhaps this was because the Germans still had a bit of medieval chivalry, or perhaps because Hitler was always eyeing the lands he occupied...... As he said, it was necessary to fight for more living space for the Germanic peoples, so the land they conquered was their own, and they did not deliberately destroy it, but often did the work of reconstruction.

Qin Chuan didn't need to care about this, and the 21st Armored Division, as an elite force, would certainly not be used for retreat, and they took the train early to retreat to the Transcaucasian region to build a defensive line.

This battalion in Qinchuan is special, they have helicopters, so of course they don't need to take a train.

So, it can be considered the easiest march.

Everyone drilled into the helicopter, and then the helicopter flew "suddenly" in the direction of the Caucasus Mountains.

Conrad and Alexander also moved to Transcaucasia with the 1st Advance Corps.

Conrad, along with the First Step, is because the helicopter still has a lot to improve...... Equipping this thing is always in use, constantly finding problems and then solving them.

The first corps is the one who uses the equipment and discovers the equipment problems, and Conrad is the one who solves them.

The reason why Alexander was transferred to the First Rank Corps was that Paulus transferred Alexander to the First Tier Corps for training.

Actually, this is more of Alexander's own meaning...... Paulus always wanted to keep Alexander by his side to take care of and protect him, but Alexander was unwilling to continue like this.

Paulus and Alexander had a heated argument over this, but in the end Alexander was able to convince his father.

Alexander was still quite useful to the First Infantry Corps, because, according to Conrad...... Hitler approved the production of helicopters, which led to a sharp increase in the pace of modification and production of helicopters, and soon another batch of 20 transport aircraft and 10 gunships rolled off the assembly line and were sent to Transcaucasia.

Needless to say, which unit will use these helicopters, of course, the first corps.

In other words, the First Legion will be made into a special unit that will be mobile by helicopters.

Alexander, on the other hand, because he had cooperated with Qin Chuan several times before, needed someone like him to be the logistics commander of the helicopter unit in the rear. Alexander was also very pleased with this assignment.

When he officially entered the First Rank Corps, he quipped: "Major, I originally wanted to dig you into the 6th Army, but I didn't expect that I was dug into the First Tier Corps by you!" ”

The helicopter was flying, and suddenly the soldiers shouted loudly out of the window.

Qin Chuan looked out the window, and a snow-white mountain peak came into view, undulating until it stretched into the distance...... The Caucasus Mountains, which have entered winter at this time, are already covered in a layer of snow, and the view from a helicopter is very different.

"The highest peak is 5,642 meters!" "And our helicopter ceiling is 7,000 meters, which means we can reach anywhere in the Caucasus Mountains," Conrad said. There is no need to trek through mountains and rivers like mountain troops, just specify a location, get there, and rappel ......"

"It won't be as simple as you think, Colonel!" Qin Chuan replied: "We are not a mountain army, we even have altitude sickness at more than 5,000 meters, and if we throw our people there, I am afraid that we will freeze to death in a few days!" ”

"Oh yes!" Conrad replied, "That is, it's time for you to train in mountain warfare!" ”

Qin Chuan couldn't help but roll his eyes, the First Step Corps really carried out all-round training like a modern special forces.

However, this seems to be indeed necessary, because it is conceivable that the greatest use of helicopters is that they can lead their troops to walk on flat ground in mountain combat, just like Conrad said, they can go wherever they want, and the altitude of more than 5,000 meters may take days, ten days, or even longer for ordinary mountain troops to climb, and some people will never even reach the designated position.

But for a helicopter, it's only a matter of ten minutes.

So, if you don't know how to fight in the mountains, it seems that you are not eligible to use helicopters...... They could have assigned helicopters to mountain troops, since it was much easier for them to practice rappelling.
