"It hurts, it hurts...... Beiming twisted his body and said in pain, "Mom, look at the eldest brother." ”

"Come on! I don't have any energy at all, I don't pretend at all. Cangming glanced at him and said.

"Ahem...... "Ahem" Zhan Changsheng clenched his fists and coughed lightly, looking at a few of them with sharp eyes.

Cangming and a few of them hurriedly reached out to cover their mouths, and said in a muffled voice, "Dad, I won't go out and talk about it." ”

"Uh-huh!" Beiming and they nodded in unison.

"Don't say it!" Ding Qihang nodded and said like a chicken.

"That's what you said." Zhan Changsheng looked at them, although his face was dark, his eyes were soft, and he said, "You have to keep your word!" ”

"Hmm!" The children nodded in unison.

"Stay!" Zhan Changsheng looked at them and said, anyway, he won't talk about the independent brigade anymore.

"Is that okay? Father. Beiming said excitedly.

"Hmm!" Zhan Changsheng nodded.

"yes, that's great." Beiming jumped up from his chair with joy.

"Honestly, sit down." Cangming pulled him to sit on the chair with Beiming, raised his eyes to look at Zhan Changshengdao, "Dad, you go on." ”

Jing Hailin looked at them and continued, "So this camouflage uniform needs to be strengthened in terms of function, and everything that can kill the enemy and protect yourself is as easy to carry as possible on your body." ”

"That's it." Ying Jiefang nodded hurriedly and said, "Uncle Jing, I'm talking about this camouflage uniform!" ”

"Where did you just go?" Jing Hailin blinked and looked at them and said.

"Daddy Jing, auspicious clothes!" Bei Ming said excitedly.

"Yes, the Gili suit was popularized in World War II and renamed the sniper suit." Jing Hailin said slowly.

"It's really appropriate, the most important thing for a sniper is to hide himself, take it by surprise, take it by surprise, and hit it with one hit." Ying Jiefang's eyes were full of energy.

Jing Hailin looked at them and continued, "In 1899, the British army invaded South Africa and fought the Anglo-Boer War with the local Dutch descendants of the Boers, which lasted for three years. The Boers had fewer troops and more British troops, and the ratio of forces between the two sides was about 1:5. But the Boers found that the British wore red uniforms, which stood out against the green of South Africa's forests and savannahs, and were extremely exposed. Inspired by this, the Boers immediately changed their costumes and guns to grass green to make it easier to hide in the dense grass jungle. The Boers often approached the British unnoticed, and suddenly attacked, catching the British by surprise, and the British had difficulty finding their targets when they wanted to. Although the war was ultimately won by the British, the British suffered more than 90,000 casualties, far exceeding the number of casualties of the Boer army.

The war made European countries realize the importance of personnel camouflage on the modern battlefield, and they changed the color of their bright military uniforms to green or yellow to achieve the purpose of concealment. ”

"It's fast enough." Ding Guoliang couldn't help but say.

"No one wants to be a live target on the battlefield." Ying Jiefang said mockingly, "But it's too cheap British, and they have done so many bad things." Said indignantly.

"Hey! You still don't listen. Jing Hailin looked at the two people who expressed their opinions.

"Second uncle, little uncle, don't quarrel." Beiming said anxiously, "Father Jing said quickly." ”

"Listen to it! Master continued. Ding Guoliang also echoed.

"After the First World War, the advent of various optical reconnaissance equipment made it difficult for soldiers wearing single-color uniforms to adapt to multi-colored backgrounds.

In 1929, Italy developed the world's first camouflage uniform, which has four colors: brown, yellow, green and yellow-brown; In 1943, Germany equipped some of its soldiers with 3-color camouflage uniforms, which were covered with irregularly shaped three-color patches. The camouflage uniforms of the German army received good results in actual combat, and later the armies of various countries followed suit, and the color of the camouflage and the shape of the patches were studied and improved. ”

Ding Haixing's glass-like eyes flowed slightly, and he asked innocently, "This person needs to be hidden, doesn't this tank warship need to be hidden?" ”

"That's right!" Jing Hailin patted his thigh and said, "What my brother and sister said is very reasonable. Camouflage can also be used on military equipment such as various aircraft and military vehicles. ”

"I'll sort it out as soon as possible and hand it over." The battle is often victorious.

"That's not going to work?" Ding Haixing and Jing Hailin immediately stopped him in unison.

"Why?" Zhan Changsheng looked at the two of them and said, "Old Jing, you speak first." ”

"It's not even designed yet! Basically, I told you that these plaques have to be scientifically designed. It's hard to just pile it up in a mess. Jing Hailin looked at him angrily and said, "And this fabric also has to be studied carefully!" It is necessary to improve the protection against infrared, ultraviolet and other night surveillance. ”

"That's right! Waterproof, breathable, sweat-absorbent, windproof, warm and non-flammable. Ding Haixing echoed casually, her tone was gentle and gentle and powerful, and she said with great interest, "Even under the climate conditions of minus 30 degrees Celsius, it can play a high performance of waterproof and cold, and can play a good role in avoiding water and wind." ”

"it, that's an exaggeration! It's not easy to protect against the cold. Zhan Changsheng said with a hint of annoyance on his face, "We mainly rely on cotton to keep warm, which is very bloated and not conducive to training." ”

"It's a real problem." Jing Hailin nodded.

"And this has to be waterproof, sweat-absorbing, and breathable, which is fundamentally contradictory." Yun Lu said in a loud voice, "It's like it's really good, it can't be used at all." ”

"So this fabric also has to be well developed." Jinghai Lin Nunu said, "It's not a matter of one or two sentences." ”

"Where's the button? How are you going to solve this outfit? Ding Haixing looked at them curiously and asked.

"Buttons? We don't need to buckle our uniforms. Ding Guoliang pointed to the black buttons on his military uniform.

"You can't do this!" Ding Haixing shook his head slightly.

"Why not, aren't we all dressed like this?" Ding Guoliang looked at her with puzzled eyes and said.

"If you're in the wild, snakes, insects, rats and ants can get in." Ding Haixing pointed to his clothes and said, "Think about why you wore leggings during the war years." ”

"This ...... Now there are combat boots, so ......" Ding Guoliang also knew that the current conditions were impossible to equip combat boots on a large scale, and most of the big-headed soldiers wore liberation shoes.

"So what do you say?" Ding Guoliang surrendered directly, "This trouser leg and cuff can be tied to prevent insects and ants, what should I do with this button here?" ”

"It's hard to sew it up, like a sea soul shirt, with a diamond." Ying Jiefang said positively.

"That's not realistic?" Zhan Changsheng immediately denied, twisted his finger lightly and said, "It seems that this is another problem?" Lao Jing, it's up to you again. Don't look at the problem as a big deal, it's really a headache. ”
