Girls Frontline: Griffin Security

"Tunnel defense tactics?" Belik asked in confusion, and then sat next to Xu Bin.

"The so-called 'tunnel defense' is to dig holes on the reverse slope. Each hole can accommodate about 5 to 10 people." Xu Bin slowly dug up another handful of soil from the ground and constructed the internal structure of the tunnel on the table:

"The only ones that can effectively strike us are helicopters and attack planes. They need to fly at low altitude and low speed at this time, so we have plenty of time to hide in the cave and avoid the artillery fire."

"But what happens next?" Belik asked anxiously, puzzled. "The enemy will take this opportunity to swarm in and block us in the tunnel."

"Haha, I don't think so." Xu Bin laughed, and then pointed to several locations on the ridgeline:

"We can dig some bunkers in these places. They don't need to be big, just big enough to hide an observer."

"Observer?"

"Yes, they are not responsible for combat. They only need to use small holes and periscopes in the bunker to monitor the movements of the enemy infantry. Once they find that the enemy intends to climb the heights, they will immediately contact the people in the tunnel. The aviation force of the Saudi Union has poor coordination with the army and usually withdraws when the infantry is taking action."

As Xu Bin spoke, he took the lighter from Bielik's hand and placed it on the far end of the table:

"At this time, we can get out of the tunnel and return to the various firing points to fight."

"........"

This tactic was so bold that Captain Belik found it difficult to accept it at first.

After thinking for a moment, he said, "What if the enemy does not consider the safety of their allies and pushes the infantry up when the air force is bombing the reverse slope? At least during World War III, the Saudi Union did something similar."

It's not his fault for being argumentative. After all, what he is studying now is a tactic that is unfamiliar to him - the commander must study it thoroughly before implementing it, otherwise it would be a disregard for the lives of the soldiers.

Xu Bin certainly didn't mind more questions. He nodded, molded the tunnel model, and said with a smile:

"In this case, we don't need to come out again, just hide in the tunnel!"

"what?"

After hearing this, Belik's jaw dropped to the ground, and he even suspected that the other party was joking with him.

Are you kidding me...What are you doing hiding in the tunnel? Waiting to die?

So he asked again: "How can we fight if we hide in the tunnel? If someone sets up their weapons in front of the cave entrance, we will be in a position of attack and defense."

This time, he no longer looked at the situation from the perspective of the "attacker" and soon became impatient.

Xu Bin remained calm. He picked up the five sponge filters again and stuffed them into the "tunnel":

"Come, let's see how you are going to annihilate the people in my tunnel."

"Heh" he snorted coldly, and then used his fingers to play the role of a soldier, and stretched them into the "tunnel"...

But at this moment, a small bamboo stick suddenly emerged from the wall at the first corner, pricking his finger and causing severe pain.

"Hiss!" Belik gasped, "What does this mean? Is this a trap from the East?"

"It's not a 'mechanism', but a firing hole~" Xu Bin pulled out the small bamboo stick from the tunnel model and showed the other party the small hole he had just dug:

"This is a shooting hole. The shooter only needs to put the muzzle of the gun upwards and can easily shoot and block the enemy from the narrow tunnel."

"What if I set you on fire?" Bielik still didn't give up. He rubbed his fingers and came up with a new plan.

"Then we need the second corner to come into play." Xu Bin pointed at the place, then picked up a little soil with two fingers and blocked it tightly:

"The second corner must be made narrow enough, and sandbags should be prepared so that when you start to spit fire, I can quickly block it to prevent the fire from spreading or the air from being sucked out by you."

"Of course, ventilation holes will be dug in the tunnel in advance," he added.

Damn, this plan doesn't work...

At this moment, the captain's mood suddenly became complicated:

On the one hand, he felt unconvinced. He was obviously a proper soldier... and an officer at that. How could he lose to the mercenary leader in front of him? (Although the other party did not give him the impression of a mercenary);

On the other hand, he felt delighted - although his superiors believed that the enemy would not attack this place, the breakthrough point of the Triangle Forest was still very close to the "Northern Guards City", a strategic location in the south. He had been anxious about not being able to find a blocking plan, but now... there seemed to be hope of holding the defense zone.

After thinking for a while, he finally came up with an attack plan:

"Then I will not seek to annihilate you, but will use cement and earth to block you in the tunnel. How can you break free?"

"Isn't this easy?" Xu Bin responded easily, making the captain almost fly into the air with joy.

"We just need to dig a backup exit in advance..." As he said this, he dug a few more small passages in the tunnel:

"When these exits are not in use, we will block them from the outside and camouflage them. When the enemy thinks that the high ground is occupied by us and starts to spread blankets to sleep, we will secretly dig through the spare exits and get out, giving them a little surprise, and then take back the high ground under the cover of night..."

"Besides, they can't completely occupy the high ground. Let's take a look at the map!"

As soon as the other party finished speaking, Bielik opened the map and simply took a look at it, and he understood...

——Every time the enemy crosses the top of a hill, they will have to bear the attack from the two adjacent hills to the south, and to the south of the southern hill there are several more hills.

With this terrain and this fighting style... unless the Sand Alliance sends all its active soldiers and lets each of them die a dozen times, I'm afraid they won't be able to take it, right?

Thinking of this, he sighed "good" three times and then applauded.

If he really had to be praised for his tactics, Xu Bin would certainly be embarrassed to admit it - this ingenious tunnel fortification was not created by him, but originated from the battlefield of the Peninsula Kingdom more than a hundred years ago, and was created by volunteer soldiers who fought against the federal devils.

The most famous application of this fortification was the Battle of Shangganling. The volunteer soldiers relied on this ingenious fortification to withstand more than 190 million artillery shells and continuous attacks from the enemy, creating a thousand-year-old army and one special hero after another.

.

By the time Captain Belik had fully trusted this tactic, it was already sunset.

Xu Bin wanted to treat him to a meal on his plateau and take some roast beef back, but the captain refused:

"It wasn't until today that I realized how many shortcomings I have, Boss Xu..." He scratched his neck sheepishly, revealing his yellow teeth. "I will ask my superiors for instructions on this tactic after I return, and call on other defense zone commanders to learn from it. Mr. Xu Bintong..., I will come to learn from you tomorrow!"

"Sure, you're welcome anytime."

Xu Bin patted him on the shoulder and sent him down the mountain - Captain Belik seemed easy to get along with.
