"So that!" Zhang Chi explained: "Defense can be roughly divided into passive defense and active defense... Passive defense is the defense method we often use, and it is also the defense method used by military squads in Shenyang. The weakness of this defense is... Every direction must be considered in all aspects. As long as a place is broken by the enemy, it is very likely to cause the collapse of the entire defense system. For the enemy, they can choose the time for attack, break through the position, the firepower required at will, and even after reconnaissing our entire defense system, then formulate a targeted attack plan for the entire system, and we can only wait!"

Wu Xuexin couldn't help but nodded. What Zhang Chi said was exactly the problems that ** had always encountered on the battlefield. ** always defended, defended, and then defended, but the Japanese army could always find a breakthrough to beat **.

"As the saying goes, there is no line of defense that cannot be broken!" Zhang Chi continued: "Although such a line of defense can take advantage of the geographical advantage and fortifications, if it is not for the construction of solid fortifications with sufficient time and sufficient materials, in the face of enemy artillery fire... this geographical advantage is basically not worth mentioning!"

Wu Xuexin nodded again to agree.

Wu Xuexin has experienced this many times when facing the Japanese army in the domestic battlefield. What's worse is... After breaking through the defense of ** again and again, the Japanese army also summarized their experience in breaking through the defense of ** again and again, so they have become familiar with the defense of ** already.

"So, this will lead to a situation where attack is greater than defense!" Zhang Chi finally concluded.

This is different from the era of cold weapons combat. Needless to say, the war in the era of cold weapons must be more defensive than attack. However, as weapons and equipment become more advanced, unless it is a special situation such as the geographical location occupied is particularly dangerous, the advantages of the defensive side will be easily resolved by weapons and equipment, thus a situation of attacking more than defense.

"Then... what the teacher means..." Wu Xuexin asked with shame.

Needless to say why Wu Xuexin is ashamed. He is proud of how many years older than Zhang Chi, and he learned ink from the military academy, especially fighting many battles with the Japanese, but he did not analyze the pros and cons of the enemy and us clearly like Zhang Chi.

But this is actually very normal... These war theories are all very common for Zhang Chi, and for people of this era, they are still mainly focused on defense. For example, France and even the whole country are trapped in the wrong military idea of ​​"complete defense", which makes jokes like "Magino Line of Defense".

To be precise, these are actually side effects of "trench warfare" during World War I... Because of the combat experience of "trench warfare" in World War I, most of the military ideas of this era were brought to the ditch where "large-scale offense will cause heavy losses, and defense will achieve great success."

This is also one of the reasons why the German "blitzkrieg" can be promoted. Most countries' military theories focus on defense, but the German army attacks, attacks, and attacks again!

"What I mean by active defense..." Zhang Chi pointed to the map and continued: "On the one hand, we must use the advantage of the combat radius of fighter jets to form an advantage of 'I can fight the enemy, but the enemy cannot beat me'. On the other hand, we must use the mobility of tanks, armored vehicles, trains, and cars, instead of using them in Shenyang as movable turrets..."

Wu Xuexin was still a little confused: "Master, if it's an offense, I know how to use these equipment. But defense..."

"Defense can also be used!" Zhang Chi replied: "So the defense we are talking about here is not to defend one place, but to defend sports. For example, we can push the defense line forward with Shenyang as the benchmark for one or two hundred kilometers, and build several defense lines within this range of two hundred kilometers. In this way, we can play the role of the combat radius of our fighter jets, and the enemy cannot attack and suppress our fighter jets."

"So, what about the mobility of the armored forces?" Wu Xuexin asked. This was a brand new battlefield mode for him.

"Of course, armored troops cannot be used only on the defense line or for logistics!" Zhang Chi replied: "They should be used as mobile troops or fast reaction troops. For example... If a line of defense is broken by the Japanese army, mobile troops mainly composed of armored troops can quickly reach the breakthrough point, eliminate the Japanese troops breaking into the defense line and fill in the gap in time. For example, we can consciously give up one, two or even more defense lines, and then suddenly use armored troops to counterattack the enemy..."

"Oh!" Wu Xuexin couldn't help but realize: "Good way! If we fight like this, we can defend as long as we want, retreat as we want, attack as we want, attack as we want, and attack as we want. The entire battlefield situation is under our control. Especially if we intentionally give up the defense line and then launch a counterattack... After the Japanese army got the defense line, they could not build solid fortifications in a short time, but our army had aircraft, tanks, and cannons that could easily destroy the Japanese army's limited defense, and at the same time they could master the time, location and firepower of the attack... Cleverly transfer the advantages of the attacking side to our side!"

"That's the reason!" Zhang Chi nodded: "That's why I said, we must 'use attack instead of defense'!"

"Yes..." Wu Xuexin nodded repeatedly: "On the surface, it seems to be attacking, but in fact it is defending, but it takes advantage of the offense without the shortcomings of defense! What a 'attack instead of defense'!"

After pausing, Wu Xuexin said with some concern: "Secretary, if you fight like this... our army will inevitably be empty. What if the Japanese encircle them from the flank?"

After Wu Xuexin said this, Zhang Chi was relieved.

What Zhang Chi feared most was that he would be complacent when he knew a new tactic, and then he thought that the Japanese would only keep attacking from the front and were tricked by his side.

In fact, interspersed and surrounded is the specialty of the Japanese. If the Japanese do not interspersed and surrounded in a large battle, they will not be called the Japanese.

Now that Wu Xuexin asks this question, it means that he has a substantial understanding of the entire strategy and tactics, not limited to the situation.

Zhang Chi nodded and said, "Don't worry about the left wing, because the left wing of our army's defense line is Liaoning Bay!"

"Yes!" Wu Xuexin nodded. With the Chinese Navy in Lushun Port, there would naturally be no Japanese Navy in Liaoning Bay.

"As for the right wing!" Zhang Chi said: "We have reconnaissance planes, a large number of people and scouts, and then you form a mobile force... Then you can defeat them before they get into place, isn't that right?"
