"So what happened to Nakajima, what happened to the tank in the three-in-one?"

Faced with the president's question, Nakajima nodded.

"The problem of the tank in the Type 3 is not very big, the time for abandonment is not too long, and the previous maintenance has been done very well, and it can already be used through simple maintenance."

"So...... Now the question is the members. The president held out a hand and scratched the back of his head. Where can I find members in a short period of time......"

Just when the president was confused, the girl suddenly interjected.

"No problem with the members~, I've already found a good person."

"Huh? When? ”

The girl smiled, and then continued: "You don't have to worry about this~, in short, the members are fine." ”

"Well~, it's good if it can be solved, it's really worthy of Xiao Yu."

"That ......" Miho suddenly raised her hand, and everyone's eyes focused on Miho.

"With the combat effectiveness of the tank in the three-in-style, it is still very difficult to face the tank of Sandas......

"Indeed." The girl nodded. "The power of the three-type seven-and-a-half-centimeter tank gun II is really limited, only 38 times the caliber makes the muzzle velocity of its shell only 668m/s, although the prototype of the Type 90 field gun has a record of breaking the M4 at 500m in the Philippine defense war, but we are facing at least the M4A3E8, when using a type of armor-piercing projectile (APHE), it can only break through 80mm armor at 1000m."

"In addition to firepower, the protection and maneuverability of the combat vehicle in the Type 3 are not ideal." The girl sighed, and then continued: "The 50/35/25 protection behind the front side of the turret can be said to be no in the face of Sandas's chariot, and the body of 50/20/8 is an even more tragic existence. The air-cooled 4-stroke V12-cylinder unified 100 diesel engine can only provide 240 horsepower, which can only make the body weighing 18.8 tons reach 38.8 km/h. ”

"Even if that's the case, there's no way about it~" The chairman still had a smile that didn't care. "In short, it can enhance our combat effectiveness~"

[You're going to be serious for me!] ]

Although she was complaining about the president in her heart, the expression on the girl's face remained the same.

"Well...... In fact, it is not without a way to enhance the combat effectiveness of the combat vehicles in the three types. ”

"Huh? Is that possible? ”

"We can at least give this thing a more powerful main gun......"

"Oh!" Yukari's eyes suddenly lit up, "You mean, try to make a five-type seven-and-a-half-centimeter chariot cannon?" ”

"That's right~, that's it." The girl smiled and nodded.

At the beginning of the war in the Chinese theater, the Japanese Army captured the Swedish Bofors 75mm anti-aircraft gun, based on which the Japanese Army copied it, and then put it into production as a four-type seven-and-a-half anti-aircraft gun. Later, the gun was redesigned to shorten the recoil length, and the design was completed in April 1944, and the trial production of two guns was completed at the Osaka Army Arsenal in July, and it was named the Type 5 7-and-a-half tank gun.

On March 9, 1945, Fuji Usono conducted a test at a shooting training range. In this test, 22 rounds of Type 4 grenades and 2 rounds of Type 3 anti-aircraft spearheads were used. On the 17th and 19th of the same month, the Type 5 Type 7 Gun (Long) 2 was installed in a prototype vehicle equipped with a cast turret, and a shooting test was conducted at the Lake Irago Shooting Range. 72 armor-piercing shells, 68 Type 4 grenades, the results of the tests were good.

This 56 times caliber 75mm gun is much more powerful, when using a type of armor piercing shell, the muzzle velocity is increased to 821 m/s, which is enough to penetrate 118 mm armor at a distance of 300 meters, and if you switch to a type 4 armor piercing shell without explosives, the penetration depth will be even higher.

"In order to enhance firepower, the Japanese Army tested this gun on the three-type medium tank, and gave it the title of three-type reform." The girl paused, and then continued: "Since this cannon has been used in history, we can completely let our Type 3 medium tank be equipped with this cannon, although it is better to change the turret of a Type 4 medium tank when changing the cannon, but I can't get this for the time being, so it is better to change the gun directly, and it is still in line with the three types of change in history." ”

"I see...... "The president tilted his head." In other words, we can increase our combat power again? ”

"That's right~" The girl smiled, and then continued: "With this cannon, the Type 3 chariot can completely break through the side of the Sherman and other heavy chariots from a long distance. ”

"That's great, Xiao Yu."

Looking at the president, who still looked like he didn't care about himself, the girl sighed again.

"Anyway......" Yuhanari raised his right hand, and then asked curiously: "Lord Bai Yu knows a lot, he is proficient in almost any tank, are you omniscient?" ”

The other girls also turned their heads and looked at the girl.

Facing the curious eyes of the girls, the girl suddenly stopped talking, and it took a while for the girl to react.

"Well~" the girl smiled wryly. "Actually, I don't know everything, I just know what I know."

"Where are you? This is not the Monogatari series, you went to the wrong set. 】

As for why the girl knows so much, it's actually very simple. First of all, it is naturally impossible for a girl who is a pseudo-military house to know so many things, and secondly, it is impossible to write down so many things, so this can only mean one thing - the girl is hanging.

Unfortunately, the girl just had a hanging in her hand to open ......

The box is a completely all-purpose battle lane tool, and it's good to use it to check information when it's not **.

Of course...... The girl actually didn't even bother to check the information, after all, she has a capable ♀ sister, and the girl's behavior also illustrates a sentence - the righteous sister is used for it.

Although the girl's answer was very vague, Yuhani didn't continue to ask, and the girl barely escaped.

"Well~, it's not too early, let's go back early, and continue to come to the battle lane after class tomorrow~"

Note 1: There is no information on the three-type medium tank on our head, all of which are from the Japanese wiki _(:з)∠)_, but the Japanese wiki is still much more credible than the Chinese wiki and Baidu Encyclopedia that have been changed randomly.

PS: 105 steamed buns are so cool! What hard armor! Awesome firepower! Awesome maneuver! There is also black technology steady! It's crazy to push a line alone~,I've uploaded this WT video to the group file.,If you're interested, you can download it and watch it~
