Very good! Du Ruolan said with great interest: Since neither the fire gun nor the bird gun can meet the needs of the war, please pay attention to the students, they are still Germans, and they have a new invention. They invented the revolting pistol, which used a steel wheel with a clockwork to rub the flint to ignite. Subsequently, the French took it to the next level and invented the flintlock pistol. Since then, flintlock pistols have been used by armies of various countries. Immediately afterwards, the Americans succeeded in developing an automatic rifle. Later, the Italians designed a double-barreled repeating pistol that fired 9 mm pistol rounds.

It was also the German Mauser brothers who invented a rear-loading single rifle with a rotary bolt locking bolt. With a magazine that can hold 8 rounds and fires 7.92 mm smokeless powder gun rounds, this is the Model 1888 Mauser rifle. Immediately, the magazine manual rifle, the Browning automatic rifle, and the assault rifle appeared one after another. During the Second World War on Earth, the former Soviet Union invented the SKS semi-automatic rifle and the AK47 automatic rifle. In the modern era, firearms have advanced by leaps and bounds.

Regarding other firearms, I will choose the most appropriate time to explain to the students. We've talked so much about rifles, but have you figured it out, what exactly is a rifle? Now I will answer you. In fact, as you all already know, a rifle is a long-barreled firearm that fires from a single soldier shoulder, mainly used to fire bullets and kill exposed living targets, and its effective range is 400 meters. Now, please discuss what other role the rifle has in actual combat, and please answer.

Li Zhuangzhuang: Report to the instructor, rifles can be used in hand-to-hand combat.

Xin Ruofei: Report to the instructor, the bayonet on the rifle is very useful, it can be used as a knife in life, and it can also be used to assassinate the enemy in hand-to-hand combat.

Lang Pot: Report to the instructor, the butt of the rifle also has a role, and can be used to fight, fight, hit, wound, and kill the enemy.

Very good! Du Ruolan said happily: The rifle also has the ability to click and kill, that is, a bayonet; The face kill ability, that is, the butt and barrel, the line kill ability, can be thrown at a short distance, killing the enemy, this is the rifle can be thrown like a javelin at a critical moment without bullets.

The rifle is the basic weapon used by the infantry alone. We have to master and understand its performance. Different types of rifles can perform different tactical missions. But the main role of the rifle is to kill and injure living targets with its firepower, spear stab and butt. Therefore, in close combat, at the final stage of solving the battle, the rifle plays an important role.

Rifles are divided into four categories according to the degree of automation: single-shot rifles, manual rifles, semi-automatic rifles, and automatic rifles. If it is classified according to the purpose of the rifle, it can also be classified in this way, and it can be divided into five categories: 1. Civilian rifles; 2. Military rifles; 3. Police rifles; 4. Assault rifles; 5. Sniper rifles. Of course, in some special battlefields, such as ancient times and modern times, there is also a rifle called a cavalry gun, which is specially used for cavalry, also called a horse gun, and there are also carbines.

Let's start with non-automatic rifles, which are the oldest traditional weapons and are generally single-shot. A semi-automatic rifle is a single-shot rifle that can automatically complete the shell removal and feeding, with a general rate of fire of 35-40 rounds per minute, and only one bullet can be fired when the trigger is pulled. Automatic rifles are rifles capable of firing in bursts, with a combat rate of fire of 40 rounds per minute for a single shot and 300-650 rounds per minute for bursts. This rifle is capable of self-loading and casing.

A sniper rifle is a point-kill weapon with an optical sighting instrument for long-range accurate shooting at a single target, with an effective range of up to 600-800 meters, and a night vision sight is also required for night shooting. The caliber of the rifle is generally divided into three types: first, the caliber below 6 mm is small-caliber; second, more than 12 mm but not more than 20 mm for large caliber; Thirdly, in between the two is the ordinary caliber. But the rifle that is usually used is a small caliber of 5-6 mm. Ask the students to answer, why do we usually choose such small-caliber rifles?

Na Feifei immediately stood up: report to the instructor, because this rifle has a large muzzle velocity, low ballistic extension, small recoil, good burst accuracy, small size, and light weight. I like such a rifle the most.

What Na Feifei said is very correct. Du Ruolan's face softened slightly, and the expression of coldness and seriousness eased slightly, and announced: I will tell you about this today. If there is anything that students don't understand, you can also talk to me during the break, and you can also communicate and discuss with each other. Now, it's time for you to complete your training tasks for this time of the day. I hope that old students and experienced students will help those new students and students who fail shooting. Disband!

After lunch, Liu Yiyi and his party went back to the barracks dormitory to rest. Of course, Liu Yiyi also rested in her dormitory. In the same dormitory as Liu Yiyi: Qian Yifan, Zhao Shiyan, Xin Ruofei, and Lu Xian'er.

Captain, have you noticed that our supervisor is young again, and his words are as sharp and pungent and humorous as when he was at the Hongguo Valley base in Maple Gorge. Xin Ruofei wasted no time in asking: Do you know why?

Xin Ruofei said as her eyes slipped to the silent Lu Xian'er.

You ask me? Liu Yiyi deliberately avoided and said: Whoever can become the roundworm in the stomach of the supervisor can answer.

Hey, captain, I don't like to hear what you say, you slip your head! Zhao Shiyan complained unceremoniously: Lu Xian'er, you said that our captain is a pun, what do you mean by having something in his words?

Lu Xian'er immediately blushed, as if a fire was burning in her face, and replied for a long time: Don't ask me!

Hey Lu Xian'er, don't you want to ask or don't want to say? Qian Yifan giggled: The matchmaker in "The Legend of the West Chamber", I think it must be our captain!

Hey, Qian Yifan, did you say that you want the captain to be a matchmaker for you? Lu Xian'er suddenly kicked the ball back to Qian Yifan: Who do you fancie?

Oh, Lu Xian'er, you pretend to be confused, I don't agree! Xin Ruofei smiled mysteriously at Lu Xian'er: If you don't admit it, then good, captain, what do you think of Lan Junguo? It's better to introduce Lan Junguo to ......

Xin Ruofei, you are sincerely angry with me! Lu Xian'er hurriedly confessed: You all saw it, what do you want me to admit?

The supervisor and Lu Xian'er are the first moon couple of our flamingo team, which deserves praise and admiration, congratulations to you Lu Xian'er! Liu Yiyi told Lu Xian'er very calmly and dignifiedly: How about waiting for the success of the time train test, taking you and the supervisor to Mars for a wedding, and giving you the most romantic and vigorous candle night in the cave room?

Well, great! Xin Ruofei suddenly said with some sadness: Can we go to Mars?

Let me remind you first, once the time train test is successful, you should quickly apply to the headquarters and join the first batch of Chinese immigrants to move to Mars!

Captain, can you still form our Flamingo team? Zhao Shiyan yearned infinitely: I must apply! When the time comes, our captain and Captain Yang, Li Zhuangzhuang and Xin Ruofei, Lu Xian'er and the supervisor, three pairs of brides and grooms!

Maybe at that time, our Zhao Shiyan will find the other half of the amphibious flight to Mars like us! Xin Ruofei was ecstatic: If Zhuang Zhuang listened, he would definitely not be able to sleep for three days and three nights!

Hey, Xin Ruofei, I can warn you, don't tell Li Zhuangzhuang, if he delays training, do you think how the supervisor will punish us? Qian Yifan seems to have some hidden words in his words: Our captain will also have insomnia!

Hehehehe, hehehe......

While everyone was laughing happily, a shout suddenly came from outside the dormitory door: Lu Xian'er-
