The TB-3 bomber, with only three self-defense machine guns, is far from enough, but when the bombers are in formation, they can use the fire cover of friendly aircraft to form a defensive network to protect themselves.

It's just that this kind of defense network is not airtight, and the best way to protect bombers is always escort fighters!

Sitting in the turret and looking at the Finnish fighters flying outside the glass frame, Ivanov was extremely nervous at this time, he was a recruit who only joined the army last year, because he passed various rotation tests and became a machine gunner.

He looked at the flying two-plane formation, his field of vision continued to expand, his palms began to sweat, the battle was about to begin!

But, then, he only saw the other party continue to climb, from the front of himself, the top of his head, brushing all at once, flying to the back.

Even if you have never flown a plane and are just playing a game of air combat, you should know that when you fly head-on, the time for the two sides to contact is very short, and it is difficult to get results if you launch an attack in a hurry at this time.

So, Bruce pulled his head and flew over the other side, and then he pulled the rod and kicked the rudder hard.

The sky was spinning, the blood was surging, the huge overload made his eyes blood-red, he looked at his dashboard with the corner of his eye, just now, he made a big overload turn.

When his eyes became clear again, he had already seen the huge group of bombers below him, and at this time, he was already behind the other party!

How to attack bomber formations? Fly to the top of the opponent's back, of course, and swoop down from behind!

That's what Bruce did.

He pushed his joystick, took his wingman, and swooped down from the sky!

In the field of vision, the outline of the DB-3 bomber became clearer and clearer, the double-engine structure, the tail turret, you can see it so clearly, and then, on the opponent's tail turret, a tongue of fire appeared.

7.62 mm machine gun, fired fiercely!

Ivanov just saw the other party flying overhead, he kept his neck up to observe, and sure enough, he found that the other party drew a beautiful arc, and attacked in turn!

He put the opponent in his sights, and then fired, but unfortunately, his bullets couldn't hit the opponent at all!

Shooting in the air is a lot, simple mechanical sights, to take into account a lot of other factors, wind speed, gravity, etc., even in later generations, before the appearance of the cannon hotline, cannon shooting in the air, is a technical job.

It looks mighty, but in fact, the bullet is still far away from Bruce.

Bruce continued to dive, getting faster and faster, almost five hundred meters away, before he pressed the fire button.

"Tom tom!" The 20 mm cannon fired at the same time, and in an instant, the engine on the left wing of the opponent emitted billowing black smoke, and the fire quickly spread!

The performance of the French fighter is not very good, but almost all the pilots who have used the cannon on it will be full of praise.

Quickly pulling the head, Bruce's plane turned from diving to climbing, and the wingman who followed him saw the appearance of the other party, and there was no need to replenish the gun.

This DB-3 bomber rolls and falls downwards, and this is just the beginning!

The ferocious volunteer pilots, piloting the fighter jets of the legal system, are like a pack of hungry wolves besieging the herd.

The battle in the air began fiercely.

"Look, another Soviet bomber, down!" At this time, on the ground, behind the Mannerheim Line, a gunner looked at the sky and said.

Beside him, there is a 50 mm anti-tank gun, which is the latest anti-tank gun to be supported, the outline is very low, the artillery bunker built here is more than 0.6 meters, the gun body will almost stick to the ground, and the entire gun position is difficult to find.

It's just that this gun does not have any markings, no factory address, year and month, and does not have any labels, only those who are most familiar with it know that this anti-tank gun, in fact, was once equipped in the German army.

The PAK38, a 50mm anti-tank gun, was a product of the Krupp company that was used to replace the 37mm anti-tank gun used in the Spanish Civil War.

However, in war, the change in the performance of weapons is quite fast. In the Spanish Civil War, 37 mm was enough, however, after the arrival, a 50 mm tank gun was needed.

Now, the 50 mm anti-tank gun is no longer guaranteed to deal with the future armor threat, so the 50 mm anti-tank gun was finally short-lived in German weapons and equipment, and gave way to the 75 mm anti-tank gun, and these eliminated ones were supported to Finland.

It's still no problem to deal with the threat of Soviet tanks now!

At the same time, the defense line here is also the area where the most fierce fighting is expected, and here is the Karelian Isthmus region!

The entire width of the isthmus is about 100 kilometers. On the Soviet side was an uninhabited desert, which was most conducive to the offensive of tank units.

At the same time, the transportation conditions in Finland are relatively good, there are four railways and ten roads leading to the northwest of Finland, so if the Soviets quickly conquer this area, they will be able to quickly break through to the main areas of Finland.

It was a major route from the Soviet Union to the interior of Finland and was strategically important. The Mannerheim Line was built here.

Historically, the Finns considered an impregnable line of defense, which did not last long, but now, the entire line of defense has been completely renewed.

There are hundreds of anti-tank guns like theirs on the entire front, and at the same time, behind the lines, there are also some tanks hidden for counter-attacks, among which there are even heavy tanks from France!

Finland is now fully mobilized, and the number of troops is still insufficient, so in addition to Finnish soldiers, there are some new faces guarding the line.

It is said that the volunteers from friendly countries speak in a variety of languages, which also brings trouble to their operations.

For example, the commander of this cannon speaks with a Polish accent and speaks English, and communicates simply.

"All cheer up, the planes of the Soviets are coming, and their tanks will come up soon!" Gun Commander Pattifo shouted, "Don't stare overhead, watch out for bombs falling for a while!" ”

Your own air force is preventing the other side's bombing, but the opponent has so many bombers that there will still be bombers to bomb.

Almost as soon as the words fell, sure enough, I saw a bomber overhead, dropping a few black bombs.

What a stinky mouth, what to say!
