Mr. Ding has many domestic anti-toxic mask samples here, and Mu Yang tried them on, feeling that breathing is still very smooth, at least there will be no suffocation, and it's not a big problem to run and jump vigorously.

  Muyang made a one-time purchase of 160 sets of 08-style gas masks, which are considered the best domestic military gas masks currently available on the market. Naturally, he wanted the best, and the price was completely acceptable - 240 yuan each. Muyang said it was no burden at all.

  After payment, Mr. Ding made several phone calls to gather 160 masks, you know, the sales volume of this thing is not very high, a military store will not have many stocks.

  Almost 40,000 yuan in goods, Mr. Ding happily sent someone to deliver the goods to his doorstep, and Mu Yang directly unloaded the goods into the first floor of the residential building in his rented community, which is now empty and can be used to store goods, much more convenient than moving to the upstairs where Mu Yang lives.

  See off the delivery staff, turn around and put on the gas mask purchased in space, Mu Yang returned home, then directly crossed back to the European war.

  "Ford!" Muyang shouted loudly outside the door.

  "Yes, sir, I'm here." Communications soldier Fort hastily ran into Mu Yang's office.

  "Notify the four squad leaders to come here for a meeting." Murong Yang was ready to start training these guys now, time was running out and couldn't be delayed.

  "Alright, sir." Ford ran out and in no time, all four of them arrived at Mu Yang's office.

  Muyang asked the four to sit down, then said: "We have many new recruits here, and those laborers who have never received training. Even for old soldiers, I am not very satisfied with their combat awareness. So we need to start training them. I've studied a method that can improve the survival rate of our soldiers."

  At this point, Mu Yang took out a diagram, which was a simple defensive trench diagram he had drawn himself. He then said to the four of them, "The Germans will definitely have an artillery bombardment before attacking, that's for sure."

  Claire and the other three nodded, this was basic common sense in battle, they didn't know why Moyang asked such a thing.

  "Look, this is a trench. What if German shells fall into the trenches?" Mu Yang continued to ask.

  "Killed in one shot." Newton replied cooperatively.

  "Clare, tell me about the casualties of our troops during the German artillery bombardment," said Mu Yang.

  "Sir, I haven't counted, but if we're lucky, after dodging the artillery fire, our regiment will probably lose twenty or thirty men. If we're unlucky, losing forty or fifty is a common occurrence." Claire said.

  "There was an even worse situation, at Verdun, my company was facing the German army's attack head-on. The Germans deployed thousands of large-caliber artillery pieces and bombarded our position for two consecutive hours. After the German artillery stopped firing, only over thirty people in my company survived."

  "And the situation of other troops in the first line of defense was not very good either, the German army broke through our defensive line because at that time we didn't have many soldiers left on the first line of defense." said Lieutenant Burton Rafford who rarely spoke.

  "That's right, this is the problem. The enemy's artillery fire will cause serious damage to our position. Actually, I've studied it before, when the Germans are shelling, they definitely won't send soldiers up to fight for the position. When they do send soldiers up, the shelling stops and we both switch to fighting over the position, isn't that right?"

  The four of them nodded in unison.

  "I've had an idea, a way to reduce casualties among our soldiers during artillery fire. We can dig some protective caves in the walls of the trenches, where the soldiers can take cover and avoid the enemy's bombardment, and then emerge when the enemy launches a charge. What do you think?" asked Mu Yang.

  The eyes of the four lit up at the same time, and they carefully thought about the method proposed by Mu Yang. As frontline soldiers, they naturally judged that the method proposed by Mu Yang would indeed have a possible defense against artillery fire.

  "The main killing power of the shell is the shock wave and shrapnel. We make a hole in the side wall of the trench, deep inside, with a small entrance, just enough for one person to crouch and crawl in, then it can be expanded appropriately inside."

  "Each one doesn't need to hide many people, five or seven is enough, at most a class of soldiers can be accommodated, we can dig many and it's also convenient for the soldiers to launch a quick attack," said Mu Yang.

  "What if the cave is collapsed by a shell?" Lieutenant Calvin Wright asked.

  "We can reinforce the entrance and walls of the cave with wooden boards. Since the entrance is small, the possibility of it being blasted down is low, and with a bit of reinforcement, there's no problem at all." Muyang drew a suggested reinforcement diagram on paper for the four to see.

  "Sir, how much effect will it have?" Claire asked.

  "I estimate that the losses will be reduced by half, or even more." Muyang replied very affirmatively. After all, the cat ear hole had been tested in wars of later generations, and Muyang still had this confidence.

  "Sir, you're really something, to have thought of such a good method. Now let's see what those Germans can do, we'll surely give them a big surprise. When they charge, we'll catch them off guard." Claire said excitedly.

  Calvin, Newton and Bolton all praised Mo Yang's invention.

  Muyang also told the three people about several variations of the anti-cannon cave, such as the oblique cave, curved cave, and T-shaped cave, which shocked the three people with Muyang's idea.

  "Now that defense is over, let's talk about offense." Muyang interrupted the four people's flattery.

  "Attack, you mean charge?"

  "Yes, charging forward, I found that our casualties during the charge are much greater than those during defense. Do you still remember the Somme River? Do you still remember Verdun? In each battle, tens of thousands of young men lost their lives, and they all fell on the road to charging forward." Mu Yang said with emotion.

  "What's another good idea you have."

  The four of them now think that Mu Yang's method is not as fanciful as they thought at the beginning, because the defensive strategy of using a bunker to counter artillery fire is actually very feasible and practical.

  "Calvin, your military posture is the most standard. You demonstrate to everyone what we look like when we attack." Murong said.

  Lieutenant Karl Wright, over 1.8 meters tall, with a strong and straight waist, immediately stood up upon hearing Mu Yang's words, picked up the rifle placed by the door, and assumed a standard advancing posture with his gun at the ready.

  Carlvin was very proud of himself, he was the first in that batch of new recruits.

  But this posture in Mu Yang's eyes, however, is so stupid. What's the difference between this and suicide? Since the emergence of machine guns, this kind of attacking posture has become clearly outdated.
