If you want to improve the accuracy of shooting only by "grinding guns in battle", it is basically impossible, after all, there are only a few hours, and sharpshooters and the like are fed with shells, and at this time there is obviously no time and no ammunition for them to waste.

But there are traces of artillery to shoot operational targets, that is, some techniques that the soldiers of this era did not know.

There was no problem in digging anti-tank trenches in the Engineer Regiment, and at the command of Major Gavrilov, the soldiers of the Engineer Regiment and the 333rd Regiment were mobilized, and half an hour later even the population of Tula was called up to dig traps...... The entire frontage, from the Yauza River to the lagoon, is a passage more than ten kilometers wide, and the layers down are full of traps.

The interesting thing about these traps is that they are filled with mud after they are dug up, and there is nothing wrong with them on the surface.

As for the tank crews and anti-tank gunners, Shulka was put in charge of "pre-war training".

"It's easy!" Shulka said: "Three guns in a group, the same for tanks, each gun at the same interval in a straight line facing the enemy, and then fired in turn, understand?" ”

The gunners were stunned when they heard this.

The commander of the tank battalion, Captain Akimchik, who was on the side, asked: "Comrade Shulka, what is the difference between this and our usual shooting?" Will this be more accurate? ”

"Of course there is a difference!" Shulka explained: "Your usual shooting is a random fight between the three cannons, and there is no mutual correction and comparison between the cannons!" ”

Captain Akimchik couldn't help but let out an "oh" when he heard this: "You mean to say...... After the first cannon is fired, we can observe the distance of the impact point from the target and compare the shots? ”

"Yes!" Shulka replied: "Because the cannons are of the same height, the same spacing, and they are lined up in a straight line facing the target...... If the first cannon misses, the second cannon can be adjusted according to the data and offset that has been obtained, and the same is true for the third cannon! ”

"Understood, Comrade Shulka!" Captain Akimchik stepped forward and saluted Shulka and said, "Very good method, there is no doubt that this will greatly improve the accuracy of hits, and it only takes simple training!" ”

So the problem was solved, and Shulka let Captain Akimchik do it.

The principle is actually very simple, other external conditions are the same, even the wind direction and wind force are basically the same, so as long as the gunner's calculation speed is fast and accurate (this is an artilleryman's ability must have), then it is difficult to miss the target with three shells.

"Comrade Captain!" An artilleryman asked Captain Akimchik: "What if you still miss the target?" ”

"Then one more round!" Without thinking about it, Captain Akimchik replied, "Otherwise, you will not be allowed to retreat even if the enemy rushes in front of you, understand?" ”

"Yes, Comrade Captain!"

Returning to the command, Shulka said to Major Gavrilov: "We need more tanks and anti-tank guns!" ”

It's a must.

The reason for this kind of tank ambush warfare will have a flaw: while trapping the enemy, one's own anti-tank guns and tanks cannot be transferred, because there are traps everywhere, abnormal traps that cannot be detected on the surface.

This meant that tanks and tank guns had to be abandoned after an ambush was exposed, as they were quickly bombarded by enemy artillery.

It is even possible that tanks and anti-tank guns will be detected by the enemy before they can be used and become useless.

So, of course, more anti-tank firepower is needed.

Major Gavrilov nodded: "I have asked for reinforcements from Moscow, and they will immediately transfer fifty anti-tank guns......"

"Fifty doors?" Shulka shook his head: "Maybe it's not enough!" ”

"That's all there is to them!" Major Gavrilov replied: "You know, Moscow threw almost all its forces and equipment to the front, even those that came in from the rear!" ”

Shulka knew this, of course, but the problem was that the difficulties lay ahead and could not be solved: the combined anti-tank fire of the 333rd Regiment and Tula was only 79 units, and an ambush would require 12 units in the first and three units at the end and three on the left and right.

This is still the bare minimum, in order to ensure that the target can be destroyed and blocked, especially the head, because the enemy tank may push the destroyed tank wreckage away, so it is necessary to equip a few more doors.

If you calculate an ambush of 20 units, including the 50 anti-tank guns newly reinforced by Moscow, can only hit about six ambushes.

Six ambushes...... Shulka didn't know how many tanks this could consume the Germans, Shul only knew that it might not be enough in real combat.

Because the Germans are not fools either, it is possible that they will suffer once or twice, and then there will be corresponding countermeasures.

But now the situation is like this, and it can only be taken one step at a time.

At least one thing that the superiors are accurate is that the enemy arrived in Tula before dawn.

They first cut off the railway south of Tula.

In fact, this was already done by the German reconnaissance detachments, which would have made it impossible for the front-line troops to return to Tula.

And just behind the line of defense of the 333rd regiment there were several railways that stretched to the front line in different directions.

So, as Major Gavrilov said, as soon as Tula, this transport hub, was occupied...... The consequences will be dire.

"Five hours!" Major Gavrilov said: "In just five hours, a group of reinforcements from Leningrad arrived here!" ”

This information made Shulka relax a little.

Although the Germans have always been known for their "blitzkrieg", it is not easy to break through this trap line in five hours under such circumstances.

Just as he was thinking about it, there was a sudden whistling of cannonballs in the sky...... The Germans went on the offensive.

If it had been before, Shulka would have had to hide in the trenches and shrunk and shiver, begging for shells not to fall near him.

But after all that he has been through, Shulka knows that there is not much difference between being scared and not being afraid...... Cannonballs won't spare you for that.

As a result, Shulka had learned to poke his head out of the sound of the shells exploding and only shrink his head when the shells blew up a cloud of mud nearby.

As a result of the observation, it was determined that the Germans were not aware of Shulka's trap tactics.

Because, their artillery preparations are still advancing layer by layer as before.

This was used to blow up and detonate mines, as well as fortifications and barbed wire, of course.

It is clear that such a bombing will not blow up the traps, but will make them more ...... Because the crater itself is an excellent trap.
