"Are you wondering why, our knights have to fight so conservatively?" Dong Kexin seemed to know, Anbi was as he thought in his heart.

"Hmmm! Isn't it war that you knights and warriors attack ordinary soldiers on the ground and consume each other's troops? ”

Dong Kexin showed a slightly embarrassed look, she was sleeping in these classes at school and didn't listen. But such a humiliating thing cannot be said.

"This reason is very simple, Xiao Lin, you can help me explain it to Sister An."

Fei Lin glanced at Dong Kexin, too lazy to demolish her.

"Now that the total combat strength of the theological armaments on both sides is similar, there are two strategies that can be adopted - either offensive or defensive." As she spoke, her hands drawing four squares in the air, representing the two tactical strategies of each theological armament on the side of the horizontal column. Four squares are a combination of four situations.

"Suppose that both sides, as you say, adopt an offensive strategy and switch hands with each other! Then, there is a high probability that both sides will have great results and at the same time heavy losses. As a result, one side may end up winning miserably! ”

As she spoke, Philin put a big red cross in the upper left corner of the box that indicated that both sides were attacking. And looked at An Biru, hoping that she understood the internal logic of a fiasco, a fiasco—the price of a fiasco, too big to be able to bear.

The understanding of the first step is important. After seeing An Biru, Fei Lin nodded before continuing to explain.

"If one side goes on the offensive, the other side theologically armed forces go on the defensive. The situation will be that the theological forces of the defending side will be able to receive more support from their own side. Multi-directional support of ground anti-aircraft fire, long-range precision sniper fire, and more. The end result is a big defeat for the attackers and a big win for the defenders. ”

Philin said, in the four square grids, one side attacks and the other defends, and in the two diagonal grids, two checks are played on the upper right and lower left. Then, we put our eyes on the last square, which indicates that both sides are on the defensive, and draw a circle in it.

"Because no one wants a miserable victory, they all want to achieve the greatest result at the lowest cost. Who knows how long the war will last, no one knows what the next battle will be, and no one knows whether the next wave of logistical supplies will be delivered in time. Therefore, use a tactical defensive position to play a strategic offensive, take a defensive position yourself, and expect the opponent to take a strategic offensive. Undoubtedly, it has become the most secure strategy. ”

Dong Kexin saw that Fei Lin had already said almost, and hurriedly said.

"That's right! Make your own good choices and expect the other party to make mistakes. Both sides decided in this way, and in the end, both sides went on the defensive. It's called 'Nash equilibrium'. Right! 'Nash equilibrium'. ”

Nash equilibrium?

An Biru repeated the noun repeatedly in her mind, and then looked at the four-square grid drawn by Fei Lin in the air. Obviously, a big win is more enticing than a big one. Under the continuous battle, no one can guarantee that the next stop will still be able to win. You only have one life, and when you die, you are gone.

"What's it called? I've never been exposed to this mindset before. An Biru asked.

"It's called 'game theory'. Of course, what I just said is only a simplified state, based on the fact that the total combat strength of the two sides of the confrontation is similar. The actual situation is much more complicated, and we have a mobile main force to create a local superiority in troops. If one point is broken in a global campaign, it will cause an avalanche of chain collapses, upsetting all balances. ”

Dong Kexin immediately answered, as if he understood very well.

"Yes, alas, there are also mobile units on the other side. There will also be mobile units of anti-mobile forces, and then it will be another game. Then, in order to avoid a crushing victory, or a big defeat, it will return to the conservative strategy of both sides. Then on a larger level, the game, the battlefield, the battle, the war, the comprehensive national strength. In the end, everything returns to the game of comprehensive national strength. ”

Fei Lin looked at Dong Kexin a little teasingly, Dong Kexin wanted to continue to brag, but suddenly became obedient and stopped talking. The one-meter-seven-eight Yanma has a well-behaved appearance that has a bit of charm.

"Actually, the fact that the Empire is so friendly to your civilizations is also the result of the game. As far as I know, the Federation's attitude towards the Third Interstellar Civilization is very problematic. At the same time, there are many forces in the various camps within the country, and they look like they are separated. These problems will eventually erupt, causing them to lose the game against the Empire. ”

Fei Lin said excitedly: "Now that the empire and the federation have reached the Nash equilibrium, they only need an opportunity to break the equilibrium. Our empire will be able to achieve all this, the ultimate victory. ”

In fact, Abiru realized early on that from the beginning of the application of theological armament, the topic gradually drifted off the center. However, she doesn't care, it's enough to listen, it's important to know more about the thinking of the people of the empire.

It's just that when she heard the end, An Biru's heart suddenly had a trace of worry. She asked leisurely, "If the Empire finally defeats the Federation and becomes the sole overlord of the human world." Will the Empire still be so merciful to us then, as it is now? ”

It is under the pressure of the enemy that the Empire adopts a peaceful and friendly interstellar policy. If there were no enemy nations, would the Holy Empire still be the same as it is now?

Fei Lin thought for a while, walked in front of An Biru, and said very seriously: "I don't know what the empire really thought at the beginning, you said before that I was brainwashed. But that's in the past, and even what started out as a lie has now become true. ”

Fei Lin glanced at An Biyu's mother and daughter, who were sitting in the corner and had not spoken, and continued: "The war of the empire is to bring permanent order and peace to the human world, and to end all exploitation and oppression in the world. It's as if my name is Firin, and I was taken for granted by me, my dad, and my grandfather since I was a child. I don't know how many generations this has been going on, so I can say that even if the empire loses all its enemies, the empire is still an empire, a holy empire. ”

An Biru was frightened by Firin's serious attitude. I immediately opened my mouth to explain something, but when the words came to my lips, I felt it. Firine replied to herself so seriously, and it seemed inappropriate to say that she was saying it casually. After thinking about it like this, I swallowed back the words that came to my mouth.

For a while, An Biru didn't know what to say. The atmosphere in the room gradually became awkward, just as Ambi was frantically thinking about how to break the silence.

Artificial intelligence, Lotta said suddenly.

"Communications from the Army Garrison."

Philin was stunned for a moment, the army garrison rarely had such direct contact, and then said, "Pick up." ”

The projection then unfolds, and images of several soldiers appear on the image. Heavily armored soldiers with heavy rifles and three men kneeling on the ground, two men and one woman, with their heads in their hands.

The two men were tall and burly, still wearing military uniforms, and they looked like the military uniforms of the Ansu New Army, which borrowed from the imperial military uniform. The girl was less conspicuous by comparison, her clothes were tattered and soaked in chunks of blood that had turned dark red.

"Sir! The two claimed to be the Ansu New Army, and said that they had something important to report to the chief. ”

"What's the matter?"

The soldier didn't know, but held the virtual projection and stretched out in front of the man in front of him. The man was allowed to look up before he dared to lift up to see Philine's half-length projection.

Just one glance, it was shocking. I didn't say a word for a long time, and I seemed to be stupid.

Firin's eyes grew colder and colder, and she asked, "Is the signal broken?" ”

This sound did not wake the man up, until a tiger roar from the soldier next to him woke him up from his intoxication. In the panic, I remembered my current situation.

"I am the Ansu New Army, Han Chi, the commander of the Second Regiment of the Eleventh Reserve Infantry Division, this is Chen Erlei, the deputy of the regiment, and this is the townsman of Xiaoming Town, Yangjiang City, Jia'er Empire. We have something important to say, and ask the Empire to save the people of Antigia from fire and water. ”
