Li Yong asked Zhang Jinsong to take his reconnaissance platoon to expand the search area as much as possible, but after another two days, there was still no situation, that is, he did not encounter his own troops and did not encounter the enemy, Li Yong told everyone not to relax, the reconnaissance platoon had to expand the search area a little more, and the main force of the company advanced in concealment, and at noon this day, there were faint bursts of gunfire and grenade explosions in front.

Li Yong ordered the troops to stop advancing, Zhang Jinsong immediately went forward to find out the situation, and after more than 20 minutes, Zhang Jinsong ran back with a few people and gasped to report: "There are our troops in front, I didn't come to the front to ask for the number, and I am carrying out an operation, it is estimated that I have hit a hard nail, and I have not gone up several times." ”

Li Yong hurriedly ordered the troops to run forward to prepare for battle, the troops trotted, and after ten minutes came to a ridge, only to see that the back of the ridge was full of soldiers wearing gray military uniforms, and there were three pillboxes on the mountain beam in front of the ridge of more than 100 meters, which were shooting non-stop, and the bullets sprayed out from the guns of the three pillboxes formed a crossfire.

On the open ground in front of the bunker lay a scattered corpse of a sacrificed soldier in a gray military uniform, Li Yong came to the back of a commander with a shell gun on his back and asked, "How is it?" The commander didn't look back and said, "It's not good, the terrain in front is too flat, there is no concealment to use, and the five demolition teams are all thrown halfway up." ”

Then he shouted, "The sixth group is ready." Li Yong saw that although several light machine guns of our army were still firing, they could not suppress the enemy's firepower at all, and hurriedly said: "Comrade, wait a minute, let's try." ”

At this time, the commander looked Li Yong and the soldiers of the special service company up and down, and saw that the weapons and equipment of the special service company were obviously taller and they were all wearing steel helmets, and asked strangely: "Which part of you are?" Li Yong replied that we belonged to the Fourth Brigade of the Second Column, and shouted to the back: "Gao Xiang, bring your platoon over." ”

This commander was of course happy to hear Li Yong say that the Second Column and the Fourth Brigade had come to help, and he also saw how the Second Column fought.

Gao Xiang's artillery platoon rushed to Li Yong's side from the back to nervously assemble the small cannon, the gun tray, the barrel, the bipod, and the sights, the soldiers were very familiar with their weapons, and the assembly was completed in a few minutes.

The soldiers of the brother unit saw that the special agent company and the equipment on their bodies were a little red, and Li Yong didn't care whether they were envious or not, and saw the assembled 60 cannon pointing at the small pillbox on the left and said: "One hundred and thirty meters in front of the left, test fire one shot." ”

As soon as the words came out, a shell hit the left rear of the small pillbox, and Li Yong continued: "Offset ten meters to the right and test firing a shot." As soon as he said that, another shell hit two meters to the right of the small pillbox.

This first real sword and gun contest The soldiers are still a little nervous, it is said that the usual training is very accurate, and the shells are not less consumed, but this real fight is still a little panicked, only more than 100 meters away can not be hit, the speed is not slow, Li Yong's order is not out of the shells, but the accuracy is not good, Li Yong did not blame the soldiers, and then ordered: "Offset to the left three meters and test a shot." ”

This next small cannonball accurately hit the top cover of the small pillbox on the left, and exploded on the top of the pillbox with a bang, only to see the machine gun in the small pillbox stopped for a minute and then fired again, Li Yong saw that the top cover of the pillbox did not penetrate, and the people inside were shocked and fainted a little after a while, and then eased up, and then ordered: "Three rapid fires." ”

As soon as Li Yong's words came out, he saw that three shells in a row all smashed on the pillbox on the left, and in a puff of smoke, the pillbox was blown up, and the fire point on the left side was immediately gone. The soldiers cheered quietly one after another, the power of the mortar was finally brought into play, and the platoon commander Gao Xiang and Li Yong lay together, turned around and glared at their fighters: "What do you shout, what is there to be happy about, just a slap away and waste two shells." ”

The soldiers pouted at each other and stopped squeaking, and Li Yong ordered again: "Target, the small pillbox on the right, test fire." "One shell hit one meter to the right of the pillbox on the right," deflected two meters to the left, and three shots fired rapidly. ”

Three more shells smashed accurately on the pillbox on the right, and three shells smashed in one place, and the pillbox on the right side was also blown to pieces in the explosion of the shells.

Li Yong looked at the big bunker in the middle that was still desperately firing and sneered: "One hundred and forty meters ahead, the target is the enemy's mother pillbox, and one shot will be test-fired." ”

After hitting two small pillboxes, the soldiers of the artillery platoon were not nervous, and the accuracy was also improved, plus the mother pillbox was relatively large, and the target was much easier to find, and the first shell accurately hit the top cover of the big pillbox, but a puff of white smoke came out of the big pillbox, and the machine gun inside did not continue to shoot.

Li Yong looked at it, good guy, this is still a big reinforced concrete bunker, see if your lid is hard or my shell is hard, and shouted loudly: "Ten rounds of rapid fire." "With the sound of the cannon ejecting the bore, the ten shells smashed on the top of the big pillbox, and after the first few rounds pierced the top cover, the last few shots drilled through the bullet hole, only to see the big pillbox being blown to pieces in a roar.

Mortars are generally composed of four parts: gun body, gun carriage, seat plate and sight. The gun body can be selected according to the distance of the firing range, the length of the gun body is generally between 1~1.5m; the gun carriage is mostly a bipod, or a tripod, which can be adjusted according to the target position and direction, and can be folded when carrying; the seat plate is the main component to bear the recoil force, and at the same time together with the bipod plays the role of supporting the mortar body; the sight is mostly an optical sight, engraved with direction and high and low division.

The main features of the mortar compared to other conventional artillery are:

(1) Ballistic curve, suitable for over-the-top shooting of targets behind concealed objects (such as hills), and direct shooting of close-range targets;

(2) Easy to load, high rate of fire (20~30 rounds / min), strong firepower, good killing effect;

To say a few more words here, to say that the maximum firing speed of this mortar is only 30 rounds per minute, which is already the limit, but Zhao Zhangcheng, the artillery general of our PLA, once used a mortar, in the case of a large elevation angle, with 12 soldiers to carry shells for him and press the fuse, and he himself operated the cannon to fire, firing more than 240 shells in six minutes at a firing rate of 40 rounds per minute, and crushing an infantry brigade of the Japanese army in one fell swoop.

Later, according to the confession of the captured Japanese prisoners, they could only see strings of shells falling from the sky, but no one knew where they came from, in fact, General Zhao Zhangcheng's combat position was only a few dozen meters away from the enemy, and this brigade, that is, an infantry battalion, was completely stunned.

(3) Light weight, small size, strong mobility, medium and small caliber mortars can be carried on horsebacks, hit and run, can quickly transfer positions;

(4) Simple structure, easy to operate, easy to mass production, low cost.

The operation and use of the mortar is also very simple, after finding and aiming at the target, the mortar shell is slid from the muzzle into the barrel, and the bottom fire of the shell hits the firing pin at the bottom of the barrel by relying on its own mass; Or it can rely on its own mass to slide to the bottom of the gun body, and after the shooter releases the firing pin, it will hit the bottom of the shell. The primer ignited the basic charge tube at the tail of the shell, and then the gunpowder tied to the additional charge pack on the outside of the shell was also ignited.

Although there is a gap between the shell and the barrel to prevent the shell from slipping, the closed air ring on the outside of the shell can still create a great pressure in the chamber, pushing the gun out of the muzzle and flying towards the target. This firing principle of the mortar determines that the mortar shell cannot be closely attached to the barrel, so it cannot rely on rifling to rotate the shell to stabilize its flight direction, but instead use the tail stabilization device to ensure its flight attitude.

Therefore, all mortar shells carry a tail fin. In addition to the tail fin, a typical mortar shell also includes a fuse, a detonator, an explosive, a projectile body, a closed air ring, a basic medicine tube, an additional charge kit, a primer and other parts.

The so-called mortar is actually a smoothbore gun, it has no rifling, it is an infantry weapon to strike surface targets, and it is one of the most important support firepower of field infantry, because of its light weight, simple structure, and more convenient for infantry to carry, it has been favored by infantry until now, but it is not the advantage of this weapon to use it to hit point targets, Li Yong also has no way, if you don't use mortars with the current equipment of the special service company, you can only send soldiers to send explosives up like brother troops.

Li Yong didn't want the soldiers to suffer casualties in the first battle, so he had to let the soldiers use mortars to hit the surface targets to hit the target point, the luck of the special service company was not bad, the enemy's bunkers were not built firmly, and the problem was solved with mortars.
