The British had not yet made up their minds whether to hand over the British sphere of influence in the east of India to Hua to manage, and Xiao Zhenlei, who had returned to the capital, did not wait for the news that Zhu Erdian asked to see, and on this day he took his secretary Xiao Gao and a few guards to the Military Command College to watch the students attend classes.

At the gate of the senior command class, Xiao Zhenlei and the others stopped, and there was an instructor among the teachers who gave lessons to the generals who were studying here. When the instructor turned around to write on the blackboard, Xiao Zhenlei immediately went in to find an empty seat and sat down, which surprised the students, these are all senior generals, there are almost no people who don't know Xiao Zhenlei, seeing Xiao Zhenlei come in, the generals couldn't sit still, Xiao Zhenlei hurriedly gestured to them to be calm.

After writing on the blackboard, the instructor turned around and said: "Just now we talked about the first basic principle of infantry defense and combat, the correct choice of the main defense direction and defense points, and now we talk about the second basic principle of infantry defense and combat, the correct deployment of troops, here we will talk about it as a company, you are all senior generals, of course you command more than one company, but you can not fail to understand the defense points of company-level combat units, I hope you can listen carefully!" ”

The instructor had obviously noticed a few more people in the classroom, but he didn't stop, but continued: "Article 2: The correct deployment of forces should be to use the main forces in the main defensive direction, relying on the main points to evacuate and conceal along the front and depth. A company is usually organized into two echelons, with 2 infantry platoons as the first echelon and 1 infantry platoon as the second echelon. When acting as a wide frontal defense in the secondary direction, it can also be deployed as an echelon of troops. This defensive principle can also be applied to the defense ?????? of divisional and regimental forces."

"The third principle. It is necessary to organize a perfect positional defense system, and how to organize it? Positions should be based on the mission, the enemy situation, and the terrain conditions. The positions of the company-level defense units usually mainly include the first echelon platoon position, the second echelon platoon position, the mortar platoon firing position, the light machine gun firing point, and the machine gun side firing point on both sides. Now there are air power and armored tank units in the war, so it is necessary to deploy anti-aircraft firing positions, anti-tank trenches and anti-tank positions, company-level observation posts, and so on! ”

At this time, one of the students raised his hand and said, "We all know this trench." It's just that this anti-tank trench you talked about, why haven't I heard it? As far as I know, the tanks of the British can cross a 1-meter-2 trench, and the general trench is useless against it, what the hell is going on with this anti-tank trench? And how to dig? ”

Hearing this, the instructor nodded and said: "Very good, the question raised by this student is very good, which shows that he listened carefully and is also thinking, so let's talk about anti-tank trenches." Since it is a trench, then it is a trench, but it is different from the infantry defensive trench we dug, it must be a slope on the side facing the enemy, and it must be vertical on the side facing the defending soldiers, and the depth must be deep enough, otherwise it will not work, why is that? ”

After drawing a figure on the blackboard, the instructor continued: "Everyone, please see. The enemy tank came and encountered the anti-tank trench dug by our side, and it drove forward along the slope of the trench until it reached the bottom of the trench, but the opposite trench wall was vertical instead of slope. In this way, the vertical wall of the trench blocks its way, and it is not an excavator. It is impossible to push the earthwork blocking it in front of it, and it has to reverse if it wants to move. This gives our anti-tank weapons the opportunity to destroy it! ”

"I see, an anti-tank trench so simply blocked the attack of a tank!" The students applauded loudly. Applause.

Xiao Zhenlei also applauded, since coming to this era, this is the first time someone has talked in front of him about the establishment of anti-tank trenches and air defense positions, you must know that now only the British and China have invented tanks, but none of them have been used on the battlefield, this instructor has already studied the tactics of dealing with tanks and aircraft, which really opened his eyes and made him sigh in his heart, I am still a capable person in China.

At this time, Xiao Zhenlei said: "Instructor, I think it is possible to lay mines at the bottom of the anti-tank trench!" ”

"Huh?" The instructor was stunned for a moment when he heard Xiao Zhenlei's words, but he quickly reacted, he immediately thought of the benefits of planting mines at the bottom of the anti-tank trench, and hurriedly praised loudly: "Good, good, this student's construction is very good, if the mine is buried at the bottom of the anti-tank trench, then the tank will not have a chance to reverse from the bottom of the trench!" ”

During the entire First World War, due to the poor performance of the tank, the ability to cross the trench was limited, and there were no anti-tank weapons in all countries, and the infantry could only expect the tank to stop due to mechanical failure, but the tank at that time had a limited ability to cross the trench and could only cross the ordinary trench, so the soldiers only needed to dig the trench deeper and wider, which was enough to contain the advance of the tank troops, but no one thought of this at that time, and it was not until the later stage of the war that anyone thought of digging the trench wide and deep to stop the enemy tank, but when the trench crossing performance of the tank was greatly reduced, Even if the trench is more than two meters wide, it may not be able to stop the advance of the tank, only digging the anti-tank trench can block the advance of the tank, the real anti-tank trench was only thought out during World War II, in the Kursk tank battle, the anti-tank trench was used by the Soviet Union and Germany, destroying a large number of tanks on both sides, but the poor Chinese army at that time was helpless to take the Japanese bean chariot because there was no anti-tank weapon, so they could only use soldiers to tie grenades and risk being killed by machine guns to rush up to blow up the tank, If you dig an anti-tank trench, you can stop the Japanese charge at a certain distance.

The instructor continued: "Now let's talk about the fourth point, which is to organize the firepower system tightly. If the enemy does not have tanks and low-altitude aircraft, our firepower will of course be mainly used to fight the enemy's infantry, and when the enemy attacks, the firepower should be used gradually, and it should not be exposed all at once. This easily gives the enemy a chance to clear the fire of the enemy. When the enemy attackes, it will definitely carry out tentative attacks and fire reconnaissance, and it is necessary to stabilize it at this time. Hide important firepower once it is exposed. It is necessary to quickly shift positions to prevent them from being cleared by enemy artillery fire."

Speaking of which, the instructor gave an example, drew a simple topographic map on the blackboard, asked the trainees to try to organize the firepower matching, and called a trainee to go to the podium and draw a firepower matchmaking map on the blackboard. Originally, these were only for company commanders and platoon commanders who needed to learn, but many of the senior generals who came here for further training were not from grassroots officers, and even if they were from grassroots units, they had never learned such a complete knowledge of the military theory system before. Learning some now will also be good for them later.

"Due to the advent of heavy machine guns, the tactics of the armies of all countries have begun to abandon the previous traditional offensive tactics of forming a phalanx and stepping on the sound of drums, this tactic is completely slaughtered in front of heavy machine guns, slaughtered in pieces, so now all countries have given up attacking in a phalanx, but scattered attacks, but the offensive tactics of various countries are not as advanced as China's offensive tactics, and our offensive tactics have formed the principle of the infantry three-three system, and the troops are very open between individual soldiers when attacking. Even so. If the defenders set up machine guns on both sides of the defensive positions, they can also inflict considerable casualties on our troops. Ladies and gentlemen, if the enemy attacks in a skirmish formation, placing heavy machine guns on both sides of the enemy's main defensive position can form a terrifying side-fire fire. We look at the formation of the enemy's offensive tactics from the front, and we feel that the enemy is scattered, but if we look at it from the side. You will find that the enemy is much denser than the front, and so on. Placing heavy machine gun fire on the flanks of the position will cause heavy casualties to the attacking enemy! ”

"The fifth principle of defense. Build fortifications, set up obstacles, and do a good job of camouflage! Once on the defensive, the troops should quickly construct fortifications and try to complete them before the enemy attacks. The setting of obstacles should be carried out in the order of first leading edge and then depth, first main direction and then secondary direction, first to defend against tank obstacles and then to defend against infantry obstacles. In order to guard against the enemy's ground and aerial reconnaissance, companies (platoons) should make full use of standard equipment and convenient equipment and adopt a variety of methods to camouflage according to the terrain, vegetation, season, and meteorological characteristics. The camouflage should meet the requirements of the battle, and it should be natural and realistic! ”

The instructor took a sip of water and continued: "In my opinion, with the current military equipment of our army, it is completely possible to give up trench warfare, that is, in front of our army, trench warfare no longer works!" ”

One of the cadets immediately asked, "Instructor, why do you say that?" If our army attacks the positions defended by the Germans, the German positions are fully fortified and have advanced weapons and equipment, although they are inferior to our army, but it is enough to fight positional warfare! ”

The instructor smiled and said, "Okay, today I will tell you about the tactics I studied on how to break through the long trench position!" I call this tactic assault tactics, also known as infiltration tactics. Using small combat units as assault units, such as squad platoon companies as combat units, looking for weak points in the defensive strength of the enemy's trench positions to break through, this tactic is still difficult to achieve in the armies of other countries for the time being, the German army can barely do, but it is still insufficient, but our army can, that is, using small-scale well-equipped and well-trained infantry to attack the weak links of the enemy's defense line to penetrate deep into the enemy's rear, and intersperse attacks back and forth on the enemy's positions, This requires equipping the small units that carry out this offensive tactic with our army's standard rifles, submachine guns, light machine guns, and even better if there are individual soldiers who can resist heavy machine guns, as well as equipping them with a large number of grenades, flamethrowers, and instant messengers, all of which our army has. The characteristic of this tactic is that it focuses on one point on a long front and makes a multi-point frontal breakthrough."

"In addition, the various arms of the armed forces work together, including infantry, artillery, armored forces, and air strike and support, and these arms work together enough to make trench warfare obsolete! Hiding in a trench thinking that the shells can't be hit, the bullets can't be hit? We have the best fighter planes in the world, which can carry out attacks in the air, first seize air supremacy, destroy the enemy's anti-aircraft firepower, and then carry out carpet bombing and strafing on the enemy's trench positions, and cooperate with the ground forces to launch an attack, no army can resist such a blow! ”

Before the class ended, when the instructor turned around to write on the blackboard, Xiao Zhenlei got up and left the classroom, and the secretary Xiao Gao behind him said as he walked: "Find me all the information of this instructor!" ”

Xiao Gao knew that this instructor was going to be lucky, and the president took a fancy to his military talent, and hurriedly agreed: "Yes, president!" (To be continued......)
