After running in the traffic trench for more than twenty minutes, several people came to Clifton's command center.

Later, when he heard that the command was located at the foot of Mount Umebrugg, Zhang Chi was a little surprised... because he did not expect Clifton to set up the command so close to the enemy.

What Zhang Chi didn't know was that Clifton did not do it because of his courage, but because he had to... The direction of the airport was flat and without any danger, and there was a lot of suppression and attack from Japanese artillery everywhere, and there was almost no place to establish a command center.

Originally, there were some safe places in Chi Yang, such as the warehouses used by the Japanese army to store fuel, or underground Chi Yuan, etc., but the Japanese had long blown up these fortifications... They would not leave these for the Americans to cause trouble.

However, some US troops wanted to stay away from the Japanese, thinking that it would be safer to stay away, but problems arose... For example, the command of the Third Battalion of the Fifth Regiment of the 6th War was located at the other end of the airport, but was hit by a Japanese mortar, which included a lieutenant colonel and five staff officers collectively injured. This situation caused the Third Battalion of the Fifth Regiment to be basically paralyzed for a period of time.

Clifton entertained Zhang Chi, Ruperts and others sat down on the shell box, then took out a pack of cigarettes and handed them to several people, saying, "Sorry, we have only these left!"

"Is it so difficult to replenish supplies?" Zhang Chi asked.

"Can you say that!" Clifton smiled bitterly, "We must make room for the equipment and ammunition... After all, eating less food will not die, and lack of ammunition and equipment is not the case!"

Zhang Chi understood what Clifton said. The US military always uses equipment and ammunition to fight. Now, when it cannot rush up, it requires the use of ammunition to slowly bomb. In addition, it has been light rain these days, and the visibility is insufficient, and the dispatch rate of transport aircraft and bombers is relatively low, which has caused the US military, which basically does not need to consider supply, to save on use.

"This reminds me of Guadalam!" Clifton, who was holding a cigarette in his mouth, patted Zhang Chi's shoulder and smiled: "Remember? He saved food at that time. It should be said that the current situation is better than that time, and this is why we can stick to it until now!"

Speaking of this, Clifton glanced at Ruperts again and said in a pun: "Of course, there is also the general's order!"

Ruperts heard Clifton's implicit voice and asked Clifton unhappily: "Col. Are you questioning my command?"

"Of course not, general!" Clifton spread his hands and replied, "Why do you think so? Look, the first regiment of the 6th War has suffered thousands of casualties, and I even sent all the engineers and guards. Is this still called disobeying orders?"

Rupertes couldn't help but speak in silence after hearing this...

Of course, the reason why Ruperts chose to remain silent was not only because Clifton was telling the truth, but also because Ruperts knew that these soldiers who were fighting against the enemy on the battlefield could not afford to offend... You must know that they fought against the enemy in an extremely difficult and tense environment, and they could be said to be on the verge of collapse. When they clashed with them at this time, who would know what would happen?!

Zhang Chi patted Clifton on the shoulder, winked him, and signaled him not to make things difficult for Rupertes.

"Tell me about the situation!" Zhang Chi said.

"I have to admit that the Japanese played very well this time!" Clifton shook his head and sighed: "They are different from the Japanese we met before, and they are very well prepared!"

As he said that, Clifton pointed to the map and said, "Look at this... From my airport north, there are the Japanese Laotuling, Death Valley, Five Brothers Mountain, Five Sisters Mountain, and Chinese Wall..."

"There is actually a Chinese wall?" Zhang Chi once again learned about the ability of Americans to call them nicknames.

This can be said to be a major feature of the Americans. For example, they usually call flamethrowers lighters, grenades, and explosives bags called bottle openers...

"Uh..." Clifton replied: "It doesn't mean it is Chinese, because the defense line built by the Japanese is a bit like the Chinese... What is the wall called it?"

"Great Wall!"

"Yes, it's the Great Wall!" Clifton replied: "That's why we call it the Chinese wall! I think the Chinese must be very good at dealing with such walls, right!"

Clifton laughed.

Then Clifton continued: "The Japanese built fortifications to cover each other and connect with each other. Each high ground has its own tunnels. No matter which high ground we occupy, it is easy to be attacked by several other high grounds... So, you know, after a lot of casualties, all we can do is to surround these high grounds with sandbags and machine guns!"

Looking at the topographic map and Clifton's commentary, Zhang Chi couldn't help but remain silent.

This kind of defense fortification of the Japanese army made Zhang Chi feel familiar, and then Zhang Chi quickly understood... This was like the tunnel used by the Volunteer Army in the War to Resist U.S. Aggression and Aid Korea, but the tunnel warfare of the Volunteer Army was even more perfect than the tunnels built by the Japanese.

So, this may be like this: First, the Chinese used tunnel warfare to deal with the Japanese on the Chinese battlefield. The Japanese learned tunnel warfare in battle, so they applied what they learned to use it in the Pacific War against Americans with superior equipment, but the Japanese further developed them into the prototype of tunnel warfare that combined tunnels and fortifications can support each other. Then, in the War to Resist U.S. Aggression and Aid Korea... The Volunteer Army summarized experience from the examples of Japanese troops fighting the US military, and promoted tunnel warfare to form a combat system.

Thinking of this, Zhang Chi couldn't help but smile. If the Japanese had known to use tunnel warfare, they might have been able to press the front line tightly on the 38th line just like the War to Resist U.S. Aggression and Aid Korea.

But even though Zhang Chi knew about tunnel warfare and even knew about tunnel warfare that was more powerful than in front of him, he still had no idea how to start with the Japanese army's defense method... tunnel warfare can be said to minimize the enemy's naval and air advantages and artillery fire advantages, and then directly deployed close combat similar to ancient sieges. The difference was that in ancient times, cold weapons such as knives and guns were used, but now they were rifles and machine guns.

This is precisely the weakness of the US military, so the US military is extremely uncomfortable.

After thinking about it, Zhang Chi asked: "I want to know... where does the water the Japanese drink come from?"
