As for the damage effect of armor-piercing bullets, it is somewhat similar to armor-piercing bullets, but the armor hole will be much smaller than that of armor-piercing bullets, because armor-piercing bullets are used to destroy armor, which is a thin high-temperature and high-speed metal jet, and due to its extremely high temperature, there will be obvious ablation marks in the inner chamber of armored vehicles.

Judging the type of bullet according to the damage of armored vehicles, it can be said that it is Lin Fei's unique skill, in this era, armored weapons have not appeared on a large scale, and anti-armor weapons have naturally not appeared, and military experts from various countries do not know much about these anti-armor weapons.

Lin Fei read the description of the damage sent by Li Ming several times, and finally determined that the shells that destroyed the invaded artillery chariots were not any kind of armor-piercing shells, armor-fragmenting shells, and armor-piercing shells, but ordinary grenades, but the charge of this grenade was large enough to blow up the invading artillery chariots.

In fact, the artillery combat vehicle of the invasion is relatively crispy, the thickness of the armor is only a few tens of millimeters, this is also a matter of no way, the armor is all steel, what is the density of steel, 7,900 kilograms per cubic meter, which means that adding one more millimeter of thickness to the armored vehicle will bring a huge weight increase, and Lin Fei's hands are not so powerful, if the armored vehicle is very heavy, it will undoubtedly fall into the dilemma of a small horse-drawn cart.

Lin Fei was relieved to see that the shells used by the Russian army were ordinary grenades, which means that at least the Russian army has not gone far in anti-armor weapons, and the Huaxia Army's advantage in armored weapons is still obvious.

Lin Fei paid attention to the shells, and began to care about the launch carrier of the shells, the Russian army originally also had howitzers, but those howitzers have never posed a threat to the invading artillery fighting vehicles, because their accuracy is not high, and they are deployed behind the battlefield, and now, this type of artillery of the Russian army seems to have a high accuracy, and they are all deployed on the battlefield.

Lin Fei believes that the Russian army is equipped with a type of anti-tank gun, which is very lightweight, and specializes in firing grenades at close range to hit invading artillery and combat vehicles.

Lin Fei's analysis is good, the Russian army uses a type of anti-tank gun, but there is no such thing as "tank" in this era, so its official name has become "anti-tank artillery".

Artillery chariots of invasion have been around for a long time, and it is impossible for countries around the world not to come up with countermeasures, Japan's water dragon cannon is a typical example, and the Russian army must of course also come up with its own countermeasures, which is this type of anti-tank artillery.

This type of anti-tank gun was made at the Vladivostok Arsenal, and the Russians have been occupying Vladivostok and other Chinese territories for decades, and they have long established various factories in it, and there will naturally be no shortage of arsenals.

The Russian army found that the accuracy of the Japanese water dragon cannon was too poor and could not be used, so it developed this type of anti-tank cannon

The Russians gave this type of anti-tank cannon a name that is not unpleasant - firefighters, and the Chinese army's plundering artillery chariot has "fire" in its name, and the fire naturally needs firefighters to extinguish it, so it has such a name.

This name has been scolded by the Russian army up and down, whether it is an officer or a soldier, there is only one reaction when they hear this name - it is too ugly, an artillery, it should always be called some majestic name, a giant beast, a magic dragon or something, but its name is a firefighter, how can people call it.

The high-ranking officer who named this type of gun was a "naming waste", and no one could do anything about it.

The firefighter anti-tank cannon caliber is 60 mm, the total weight is 0.7 tons, the gun truck has rubber tires, rubber tires are also Lin Fei's first creation, learned by the Russians, and the gun body is also equipped with a hydraulic regression machine, which is a technology that Lin Fei sold to foreign countries a long time ago, and now it is also used by the Russians.

Although Lin Fei didn't know the details of this type of anti-tank cannon, Lin Fei could think of a way to restrain it, that is, to use the plundering artillery chariot to deal with it.

The anti-chariot cannon itself is to restrain the artillery chariot of invasion, and now Lin Fei actually let the artillery chariot of invasion deal with it, it sounds incredible, but in fact, Lin Fei has his own reason for doing this.

In the description, Lin Fei learned that these artillery had no power plant, and that short-distance movement could only be pushed by people, and long-distance mobility could only be driven by horses, so its mobility was far behind that of the invaded artillery vehicles.

As long as the mobility of the predatory artillery chariot is used, the firefighter anti-chariot cannon is no match.

Lin Fei then designed tactics for the front-line Huaxia Army, and asked Xiyun to send it to Li Mingming, Li Mingming received Lin Fei's tactics, opened it and looked at it, and couldn't help but be disappointed, Li Mingming originally thought that Lin Fei would take this opportunity to equip the troops with a new generation of artillery combat vehicles, but in Lin Fei's tactics, there was no shadow of a new generation of artillery combat vehicles at all.

Li Ming immediately deployed Lin Fei's tactics, and the Huaxia Army immediately moved.

On this day, ten bridge-building vehicles approached the Russian position, attacking in exactly the same way, each of which was flanked by an invading artillery vehicle.

On the Russian position, everyone was excited about the firefighters' anti-tank artillery, and the Russian army, which had been bullied by the plundering artillery chariots, finally saw something that could restrain the invading artillery chariots.

When the Russian army saw the bridge-building chariot and the predatory artillery chariot approaching their positions again, they immediately dispatched firefighters to counter the chariot artillery.

Previously, the firefighters' anti-tank cannon had been hiding on the other side of the high slope, and after receiving the order to dispatch, more than a dozen artillery men pushed it up from under the high slope, aiming at the predatory artillery chariot, ready to fire.

The firefighters' anti-tank gunners were all well-trained, and the time from aiming to firing did not take more than a minute, and while they were nervously aiming, the predatory artillery vehicle suddenly moved.

The plundering artillery chariot did not move to the side of the trench, but moved along the trench to the other side of the trench, which can stump the firefighters' anti-chariot artillery, once the artillery chariot of the plundering changed position, the muzzle pointing had to change, and the gun body did not have the function of 360 degrees rotation, to change the muzzle pointing, the gun carriage had to be moved.

When the Russian artillery was moving the artillery wagon, the plundering artillery chariot stopped and opened fire, after all, the plundering artillery chariot is a weapon with its own power plant, whether it is maneuvering or stopping, the speed is much faster than the fireman's anti-chariot gun.

As soon as the plundering artillery chariot stopped, immediately adjusted the muzzle and aimed at the firefighters' anti-chariot cannons, the plundering artillery chariot just did not have the ability to fire cannons while moving, if there was, there was no need to stop and aim at such trouble, and it was directly bombarded with one shot.

The predatory artillery chariot quickly completed aiming, and the heavy artillery exploded, and the shells landed precisely on the side of the firefighters' anti-tank guns, and the fragments instantly killed several gunners.

After a shot hits, the firefighters' anti-tank cannon fire process must be slowed down, and they completely lose the ability to compete with the predatory artillery tank.

The plundering artillery chariots fired one after another, and this time the shells hit more accurately than the last time, directly hitting the guns of the firefighters' anti-combat vehicles, and the gun wagons and barrels were all blown up.

In this way, the thirty firefighters and anti-tank guns dispatched by the Russian army have all become broken copper.

The Russian army only has a total of thirty firefighters and anti-tank cannons, and once they are destroyed, the Huaxia Army will have nothing to fear.

However, the Huaxia Army did not know how many firefighters against the tank artillery in the Russian army, and did not dare to attack easily, but waited outside the trench until they waited for half an hour, and still did not see the firefighters anti-tank guns come out, and this time they attacked according to the original plan.

While the bridge-building chariots were erecting improvised bridges, the marauding artillery chariots still did not dare to be careless, staring closely at the high slope behind the concrete wall.

The bridge-building chariot came to the edge of the trench and began to build a bridge, and the Russian troops on the opposite side had never seen such a thing, and they all looked at it in alarm, only to see that this kind of thing was carrying a folded iron plate on its back (the bridge board of the bridge-building chariot was a thick wooden plank, and the outside was wrapped with iron sheets, which looked like iron, and the reason why wooden planks were used was because the steel was too heavy).

Amid the roar of the machine, the iron plate slowly unfolded and was erected on the trench, and in this way a simple bridge was erected over the trench, and it took no more than twenty minutes before and after.

The artillery chariots of the invasion swept the firefighters' anti-chariot guns before, which swept away the confidence and will to fight of the Russian army, and now the Russian army has seen something they have never seen before, and they are even more nervous and frightened, and many people have deserted and fled from their positions.

In fact, the Russian soldiers have this kind of behavior of escaping, and they are not to blame, if they want to blame, they will blame the top of the Russian army, and the top of the Russian army put the plan of the whole army to retreat in an important position when formulating the defense plan of the three surname cities, that is to say, all the Russian troops know that we may evacuate the three surname cities, which will directly lead to a sharp decrease in the will to fight.

After the three surnamed cities, there is Heilongjiang, and after Heilongjiang, it is Russian territory, these places were taken by Russia from the Qing State, and the Russians generally believed that Lin Fei would never dare to attack these Russian territories.

The Russian army had a weak will to fight, and before the war began, it hid in its heart the idea of "it doesn't matter if we can't win, we can retreat", how can this battle be fought.

The bridge-building chariots built improvised bridges, and one after another fire dragon chariots rushed over, approached the concrete wall of the Russian army, sprayed gasoline, ignited gasoline, and covered all the Russian troops in flames.

Surrounded by flames, the Russian army could only retreat in embarrassment, away from the sea of fire, as soon as the Russian army left the concrete wall, the Huaxia army moved here, and the invaded artillery chariots concentrated their firepower and hit the shells on the concrete wall, blasting the wall into huge holes.
