If a region with the highest degree of air defense is the most important local administrative facility, such as a building of the presidential palace, then the density of air defense and firepower at a military airport is generally the highest in military airports.

Of course, this was some time after the start of World War II.

Because in the early period of Barbarossa, the Soviet military airfields ignored the deployment of air defense forces (although, in that case, the air defense forces did not seem to be very effective), which led to the complete loss of air supremacy in the combat area.

As for the reason?

Quite simply, most of the military planes of all kinds were destroyed in the airfield, and many of them were destroyed on the ground on the runway or even in the hangar before they could take off.

Although a small number of Soviet air forces were able to rise into the air and fight back, two fists were invincible to four hands, and this rule was completely verified in the tragic battles at that time.

The few fighters that were able to rise into the air to meet the attack were easily beaten to death by the escort fighters of the German attack group.

It can be said that in the early stage of Barbarossa, in addition to various factors that cannot be ignored, the early loss of air supremacy in most of the warring areas was also a very important factor.

Well...... The Barbarossa plan is completely out of step with the current Zhang Shixin.

However, it is also undeniable that Zhang Shixin attaches great importance to air supremacy. Because there are many times when it is more practical to passively carry out air defense battles than to give the other side a fairly thorough draw.

Moreover, the air defense of military airfields in this period was ...... In terms of a fairly smooth offensive with the attack aircraft group, it is almost negligible.

Because even with a small number of anti-aircraft guns, then a large number of dive bombers are also not decorations or the presence of a visit.

Because of the design principle of the dive bomber. It is quite suitable for hitting relatively fixed targets, and anti-aircraft artillery is also in this category.

Attacking anti-aircraft guns with dive bombers is actually quite dangerous, because the opposing gunners, as long as they are not rookies, have a certain chance of shooting down the plane before the dive bombers drop their bombs.

So, these dive bombers became the battle damage that was shot down by several damaged planes to declare that the battle was not a complete victory. It can only be regarded as a big victory worthy of flaunting.

When the air defense forces at these airfields were routed, the dive bombers did something about it.

That is, in the case of horizontal bombing, a small number of "fish that slip through the net" appear, which is a very normal tactic for a mixed bombing unit. After all, carpet horizontal bombing is to divide most of an area. Cause very eye damage. The dive bomber, on the other hand, is to bomb the remaining areas with relative precision and inflict a more serious blow on the enemy.

In the case of a military airfield, about seven kilometres south of Madrid, a large number of facilities, including hangars and runways, were reduced to rubble by a dense barrage of aerial bombs after horizontal bombing by more than a dozen medium-sized bombers. Sometimes, however, some airplanes or small buildings on the runway will get away with it, and dive bombers will be after horizontal bombing. Strike at these targets with relative precision, and try not to leave behind facilities and materials that could be reused by the enemy in a short period of time.

In this case, when the bomber fleet returned, several airfields of the Spanish Republic that had been targeted would not be able to return to service in a short period of time.

This is also the main purpose of Zhang Shixin's proposal for this operation.

Because, without the interference of the enemy's air forces, the ground forces will be able to fight more smoothly.

As for the air battle over Madrid, it is also coming to an end.

After more than an hour of fighting, Zhang Shixin's fighter group sent a large number of fighters from the Spanish Republic and the international column to hell.

But the fighter aviation, including the Condor Corps, also suffered considerable losses.

Compared with the victory of the bomber group, the air battle over Madrid was, at best, an overall passable victory.

Because although there is a certain gap in the number of fighters between the two sides, a considerable number of losses in the fighter group on Zhang Shixin's side were caused by some elite ace pilots of the international column.

Compared with many Condor Legion and Franco's fighter pilots whose level is only a little better than that of ordinary civilian pilots (the German pilots at this time have not experienced the real war tempering, so it is not the German Eagle Legion that has a fairly good record and ability a few years later, and a large number of elites have appeared in the German pilots, and it is more after experiencing the British air battle and the baptism of the air war on the Eastern Front. The pilots of the international column have a slightly better average ability, which is one of the important factors that led to the fact that this air battle almost did not result in a crushing victory.

And there is another very important factor, that is, the pilots of the international column, most of them are active Soviet Air Force pilots, and they are quite familiar with the combat mode of most of the members of the Condor Legion, which is also the most direct reason why the Condor Legion was slapped in the face hard......

As for why this is happening?

The reason is also very simple, that is, a few years ago, Germany had to reach a series of military cooperation with the Soviet Union in the face of the Treaty of Versailles. Among them, German pilots were trained in the Soviet Union.

Most of the pilots of the Condor Regiment were either trained in the Soviet Union or the instructors were trained in the Soviet Union. It can be said that this can be called an air battle between a master and an apprentice.

If it weren't for the fact that the number of fighters between the two sides was too far apart, it would have been difficult to do it, and this time the Condor Legion and Franco's fighter formation would really be defeated by the other side.

Of course, the overall strength is superior, and Zhang Shixin's fighter formation running to escort the bombers is also a very important factor.

But no matter what, a big victory and a passable victory have definitely established the power of Zhang Shixin's side. For a long time, it will be enough to dominate the skies of Madrid.

……………………………………………… Dividing Line................................................

The end of the air war means that the military operation from the ground has entered the stage of full development.

Zhang Shixin's flight unit and fighter group still returned to the town guarded by only about one regiment of troops to carry out supplies and simple maintenance.

The bomber group was summoned back to the space by Zhang Shixin, after all, the fighters encountered the enemy's surprise attack, and they still had some ability to fight back. But if the bomber group is also placed on both sides of the runway, which is not even a rudimentary airport, it is difficult for Zhang Shixin to guarantee that after the other party discovers this situation, even if a few front teeth are knocked out by the defenders, Zhang Shixin will lose a large number of planes.

So. In order to avoid such a situation, Zhang Shixin could only endure the six-hour cooldown time for sorties.

Anyway. The BF-109S with rockets mounted on them is in a sense. can be used as a ground attack aircraft.

……

Just like yesterday's battle arrangement, Zhang Shixin and others launched an all-out onslaught on Madrid from three directions: east, west, and north.

In contrast to Zhang Shixin's troops, there was a perimeter defense line composed of about a number of infantry divisions and a small number of artillery units.

Zhang Shixin is in the position of commander of the M6 tank. After hearing the information discovered by the BF-109HS, he was rather speechless.

Because he couldn't figure out what the Spanish Republic and the international column were going to do?

Under normal circumstances, if you take this battle layout, you will either have no troops to use...... All right. Zhang Shixin is not optimistic to this point.

After all, in the battle a few days ago, the enemy troops he could kill and wound seemed to be quite limited, at best about a division, maybe not 7,000 people.

Therefore, this level of battle damage makes the enemy's strength lack to such an extent, which is obviously nonsense.

But Zhang Shixin quickly thought of another possibility, that is, the other party should want to turn the city of Madrid into a main battlefield and drag them into the quagmire of street fighting.

However, Zhang Shixin is in another world, and in addition to the title of defense master, he also has the title of street fighting expert.

In the case of the latter, in fact, it is more dependent on the various kinds of help provided by the system to achieve such results.

Therefore, to a large extent, Zhang Shixin is not very afraid of street fighting, because street fighting is more difficult for him than in the field area, suddenly encountering the main force of the enemy army to fight an encounter.

Although there is a system that cheats on the general subsidy, this is Zhang Shixin's ability, and it is an undeniable fact.

Putting aside his own advantages and giving full play to his shortcomings, for Zhang Shixin, it is undoubtedly a move to have his brain caught in the door.

"Before that, let's take care of the people in front of you." Zhang Shixin quickly issued an order for all units to enter the combat state.

……

If someone has a certain amount of research on Zhang Shixin's tactics, then they will find that Zhang Shixin's tactics are quite boring.

When attacking, it is more likely to use a large number of artillery and use the ability of Eagle Eye to make up for it, tear apart the opponent's defense points or greatly weaken them.

Then, with a large number of tanks, the infantry and tanks were coordinated, and under the cover of extended artillery fire, they attacked the enemy's front defense area that had been blown to pieces, and harvested the lives of those enemy troops who could only carry out extremely weak resistance and could not effectively form resistance.

When the troops on the front line advance to a certain area, the artillery units advance separately and continue to provide relatively accurate fire support for the troops on the front line within the effective range of the Hawkeye.

This is the way Zhang Shixin mainly fights in the case of an offensive situation.

It seems to be quite boring, but it has to be said that such a tactic is very effective in many aspects, especially in terms of attack coordination of troops.

There is an old saying: Ideas are not afraid of being old, as long as they work.

It can be said that this set of offensive methods is also quite effective for Zhang Shixin. Although the aviation team had already joined at this time, for Zhang Shixin, this relatively "primitive" set of infantry artillery coordination, as long as it could still play a fairly effective tactical role in the appropriate area, then there was no reason for it to be directly abandoned.

In fact. What Zhang Shixin didn't know was that his set of infantry artillery coordination, before the emergence of high-performance surveillance satellites, if he wanted to say that he was backward, then he could only rely on coordinates to cover the artillery bombardment, and it was even possible to smash his own people's infantry and artillery coordination tactics, how could it be embarrassing?

Because, at this time, although there is already a theoretical point of view on the coordination of infantry and artillery. However, after quite some time, the artillery, after the advance of the front-line troops, was often able to carry out only covering shelling of other areas, and not direct support. is afraid that if a fire support comes down, their own stormtroopers will be bombed by them and they will not be able to take care of themselves. There is a very direct relationship.

After all, no matter how experienced artillerymen. It's hard to guarantee that you won't blow up your own people because of some nonsense......

It can be said that the combat effectiveness of Zhang Shixin's infantry and tank artillery coordination tactics is actually no less than the overall combat effectiveness brought about by the use of a large number of high-tech modern infantry and tank artillery coordination tactics.

After all. Excluding factors such as fire control and laser guidance, satellite-guided artillery attacks are not necessarily more accurate than Zhang Shixin's hawk-eye gunners.

It can be said that Zhang Shixin's artillery unit. The Summoner Gunner is a bug that surpasses common sense.

As for the question of the accuracy of shelling...... Modern artillery can often achieve an accuracy of less than 0.25, or even a smaller value, in this case, if the old things with an accuracy of more than 0.5 are not comparable to the other party, then, modern military personnel can directly dig a pit and bury themselves.

……

"Put !!" The commanders of self-propelled artillery units, which were independently organized, loudly gave the command for shelling in the communicator.

In less than two seconds, the total number exceeded 300 M12, Crusader SP self-propelled howitzers, and the gunner quickly pressed the launch button.

All of a sudden, high-explosive grenades with a caliber of 122mm or 155mm of more than 300 rounds quickly deloaded and fired at their respective landing circles.

……

What Zhang Shixin didn't know was that the defense of Madrid in this world had changed because of his appearance.

First of all, it is not that the Spanish Republic of this world does not have the opportunity to evacuate the civilians of Madrid, but that the Spanish Republic wants these civilians to live and die with Madrid. Although a large number of civilians do not have such thoughts in their hearts, they prefer to leave this hellish city and live elsewhere.

As for why?

It's very simple, because including Zhang Shixin's troops, his forces on this side did not effectively encircle Madrid, not even encircle, at least, Franco's troops were generally not as strong as Zhang Shixin's original world, and at the same time, the Italians were defeated by Zhang Shixin, and then under pressure from the Germans, they had to give up their plans to fish in troubled waters.

Compared with the world where Zhang Shixin is located, there are tens of thousands of fewer Italian invading troops, which also led to the Battle of Madrid in this world, not a siege battle, because south of Madrid, it is still under the control of the Spanish Republic and the international column. This also led to a campaign in which Zhang Shixin's side was only able to attack from three directions.

Under this premise, the Spanish Republic, led by Ranierin, has every opportunity to evacuate civilians from Madrid, a city that is about to be plunged into war.

On the other hand, that is, the German Condor Army, in fact, has become a commandable force of Zhang Shixin.

This also led to a certain fat man named Goering, who did not have a chance to say that:

"We're going to try carpet bombing, what kind of impact will it have on civilians."

It can be said that there are many changes in the place, and the most unexpected thing for Zhang Shixin is that the division that intercepted him is not a Spanish regular army at all, let alone an international column, but a civilian army temporarily armed.

These people are not effectively trained and even less adequately armed.

What they have is probably just the safety of their families who are threatened, and the desire to protect their families......

It's just that this alone is not enough to resist Zhang Shixin's summoners who are armed to the teeth.

……

At the time of the bombardment, several young men who looked to be less than twenty years old were sitting together, and they were talking about the air battle, which had ended less than half an hour.

"Xi'an, in the air battle just now, it seems that a lot of planes have fallen into Madrid, and I'm worried about my mother."

"Huso, we are also worried about our families, but we are now soldiers, and all we can do is protect them from the invaders."

"Xi'an, why is there a war? Although we can only help with the housework at home now, and we want to go to school, everything that was not so good before was much better than the war. ”

"Husuo, I know very well what you said, but what those big people think is not what we can imagine at all...... Well? There seemed to be some sound in the sky. ”

Several teenagers with old rifles on their backs also heard what looked like something was cutting through the sky. They wondered what it was, because they had never heard it before.

Not only them, but also many Spanish "soldiers" in the region also stood up and looked curiously at the eastern sky......

If a veteran, or a recruit, knows about it, he will be frightened by such a sound and run away or lie on the ground on the spot, resigned to fate.

But for most of these "soldiers", who are not even militiamen......

Their ignorance......

Their curiosity......

will add a heavy touch of blood to Zhang Shixin's "sin". (To be continued......)
