Xu Jianguo looked at Ma Guoliang, who was thinking seriously beside him. After a brief pause, he continued, "Of course, relying entirely on resin to block bullets is not very realistic. At this time, we have to rely on the second layer of ceramic to resist. You may not know that the Mohs hardness of ceramic is usually 6.5-9.0, while the hardness of ordinary steel is only 4.0-6.0. At this hardness, ceramic is very likely to keep bullets out. And don't be fooled by ceramic's brittleness. Its benefits are not just reflected in its hardness. In addition to being hard, ceramic also has high chemical stability, high temperature resistance, wear resistance, and corrosion resistance."
"If a bullet shatters the ceramic layer in the helmet, it means the bullet's impact has been weakened by at least 50%. The remaining third layer of steel, fourth layer of ceramic, and fifth layer of resin are then fully capable of blocking the remaining impact of the bullet. Of course, I'm only talking about close-range shooting. If a bullet is fired from a hundred meters away on the battlefield, the helmet I designed will be 100% safe."
Xu Jianguo finished explaining the design principles of the tactical helmet in one breath, then thought for a moment and continued, "Uh... Commander, let me add that large-caliber sniper bullets, armor-piercing rounds, or artillery shells are not within the defense range."
After listening to Xu Jianguo's narration, Ma Guoliang remained silent for a long time. After a while, he finally asked, "What caliber do you mean by large-caliber sniper bullets?"
"According to my speculation, there is no problem with sniper bullets reaching 15-20mm, but the targets of such sniper rifles are usually not people, but equipment as the primary target, such as vehicles or aircraft. In addition, considering the issues of recoil and portability, the best handheld light weapons can do is like this, of course, shoulder-fired rocket launchers or missiles are excluded." Xu Jianguo continued.
"Huh, good thing I didn't leave today, otherwise I wouldn't know that you have so much useful information in your head. When you finish the project at hand, please prepare some materials for me, and then I will organize all the officers and soldiers in the base, and you will give them a good lesson to let them know that if they keep guarding the junk in their heads all day long, they will be eliminated sooner or later!" Ma Guoliang exhaled heavily and spoke.
To be honest, after listening to Xu Jianguo's explanation, Ma Guoliang felt a little nervous. This feeling was something he had never experienced when facing enemy artillery fire on the battlefield.
It has been almost ten years since the last large-scale war ended, and he cannot imagine what the current war situation is like.
If weapons and equipment are really developed as Xu Jianguo said, then these veterans from the army will no longer have any advantages.
Xu Jianguo seemed to see the worry in Ma Guoliang's heart, so he said, "Commander, you don't have to worry. Although our country is still very backward, it is not standing still. All scientific researchers are working hard. The situation you are worried about will not happen. I can assure you of this!"
After listening to Xu Jianguo, Ma Guoliang remained silent for a long time. Instead, he stared into his eyes. After a moment, a knowing smile appeared on his face. He said, "Boy, I feel much more at ease after hearing what you said! However, what I said before still needs to be carried out. We must change the thinking of these people below. I will also talk to the old leader and see if we can let our Binhai base be a pilot project. If you speak well, let all the officers and soldiers of the army come here one by one to learn from you!"
Xu Jianguo felt a headache when he heard this and immediately said, "Commander, please forgive me. You want me, a young man who has never been to the battlefield, to talk about war to a group of veterans. Isn't this ridiculous?"
"That's the big deal. You are talking about military theory, not about deploying troops. What is there that you can't say?" Ma Guoliang said.
"No, no, absolutely not. Let me organize the materials first. If you think the materials are good enough, you can leave the teaching job to the old professors in the military academy!" Xu Jianguo still refused.
Ma Guoliang thought about it, looked at Xu Jianguo again, and finally nodded and said, "Okay, there's no rush. For now, you should focus on project development. Let me think about it carefully."
When Xu Jianguo heard this, he breathed a sigh of relief and said with a smile, "Okay!"
After the two chatted for a while, Li Delong, Tai Wei and others walked in from outside with lunch boxes.
After Xu Jianguo cleaned up the workbench he used for drawing in the inner room, he accompanied Ma Guoliang to have lunch, while Li Delong and others were in the outer room, eating around the stove. No matter how Xu Jianguo called them, they were unwilling to go into the inner room to eat, which made Tai Wei laugh.
After lunch, Ma Guoliang led Tai Wei away. Before leaving, he specially encouraged Li Delong and others. This made the six of them happy for the whole afternoon. They all had smiles on their faces while working, feeling like they had brought honor to their family.
The focus of the afternoon's work was still on the production of tactical helmets. Xu Jianguo and several people combined the double ceramic layer of cast natural resin with the steel plate to form a sandwich structure.
Then the prepared external accessory clips were fixed to the helmet with rivets. The purpose of these clips is to match other accessories designed by Xu Jianguo in the future. For example, the night vision goggles that are about to be manufactured can be fixed to the helmet with clips. When needed, the wearer only needs to flip the night vision goggles down to start using them, which is convenient and quick.
When three brand new tactical helmets appeared on the operating table, smiles appeared on the faces of everyone in the small workshop.
"Okay, the main work has been completed. As long as the lining and straps are done, it will be completely finished." Xu Jianguo said.
"Mr. Xu, let me handle the lining and strapping. My mother is a tailor and I've been learning from her since I was a child. I'm sure I can do it well!" At this time, a worker named Liu Yong spoke up.
Xu Jianguo didn't refuse when he heard it. He smiled and said, "Okay, I'll leave it to you. Find someone to help you and teach him. We still have a lot of needlework to do in the future, so it's a good opportunity to learn in advance!"
"Okay!" Liu Yong said.
After finishing the work on the helmet, it was already four o'clock in the afternoon. Xu Jianguo did not continue to make the night vision goggles, but led a few people back to the inner room.
He picked up the kettle on the stove and brewed a large pot of tea for everyone. Then he said, "This project is currently 80% complete. The last item left is the night vision device, which is also the most technically difficult. Let me briefly explain the principles of the night vision device and the future division of labor."
"Okay!" Everyone agreed, then took out pens and notebooks from their pockets and listened carefully.
