Ordinary military and police forces generally don’t pay attention to these details.

Only IPSC-type shooting competition athletes or skilled regular gun users would consider these factors.

Gu Ji asked about the bullet data only to quickly understand the ammunition performance, after all, he had only used training powder bullets and standard bullets, never rubber bullets.

For actual combat, not understanding the weapons and ammunition being used is a very fatal mistake.

Especially in terms of range and accuracy.

"A 100-meter range, it’s quite adequate."

The effective range of a normal MP5 is 200 meters, Wu Kang took a bullet from the box.

The structure and material of rubber bullets are basically the same as ordinary bullets; the only difference is that the lead or steel bullet head is replaced with a solid rubber head, and a lead base is used to prevent being melted by high-temperature gunpowder.

Theoretically, the rubber bullet head has a cushioning effect, causing less damage to the human body.

But in actual use, its lethality is still considerable, with close-range shooting easily penetrating the human body, causing bleeding or death.

Gu Ji loaded the bullets into the MP5 magazine, counting the spare, carrying a total of three magazines.

Although the submachine gun’s firing rate is very fast, with small recoil, better suited for suppressive fire, since Jingshang Gaoming said rubber bullet accuracy is poor, it means they would more often use burst fire like a rifle, instead of full auto mode, three magazines are enough for them.

Chen Zhiyu and Zeng Dan only used USP pistols.

If not for fear of exposing his identity, Gu Ji actually wanted Chen Zhiyu to also use the MP5 submachine gun, concentrating firepower, after all this chick did better than him with the Type 79 and Type 85 submachine guns during school.

MP5 is considered a famous old gun, ranking first among submachine guns globally; although long replaced by various new weapons, it still serves in military police and security forces worldwide.

Gu Ji has often played it in games, although he never touched it in real life.

He adjusted the telescoping stock to a comfortable position, strapped it on, and quickly found the most comfortable grip for holding the gun.

Wu Kang also kept adjusting, with the gun stock against his shoulder and his left hand supporting the forearm.

Turning his head, he saw that Gu Ji and Gao Bo’s left hands were not under the forearm but, like using the Type 95 rifle, were grabbing the gun’s forearm.

The conventional rifle holding methods basically have four types:

Grabbing the forearm is their special police’s most common gun holding posture; if the index finger is extended, it’s the Mapuge shooting method, the biggest advantage is rapid aiming, particularly suitable for CQB combat, but it easily causes arm muscle fatigue over time;

Then there’s his current method of supporting the forearm, to cooperate with the skeletal support method, allowing the elbow’s bones to form stable support, with high single-shot accuracy, almost suitable for all firearms, especially short submachine guns;

Another is to hug the region where the magazine connects with the gun body, saving effort, alleviating arm fatigue;

Finally, directly grabbing the magazine, only suitable for confined spaces, or using the forearm as a support point, without places to grip, generally very seldom used.

From here, Wu Kang could discern Gu Ji, Gao Bo’s completely different combat styles from his own.

"The Police Headquarters’ body armor is noticeably weaker than Liangben’s model!"

Gao Bo put the black level IIIA body armor over his clothes; this soft body armor can only block 9mm handgun bullets, the most commonly used police body armor.

Perhaps it suffices for ordinary operations, but he just witnessed the M4 rifle at the funeral; this level of body armor and bulletproof shields simply cannot withstand it.

Gu Ji inserted the magazine into the chest mounted magazine pouch in his body armor.

"Liangben’s body armor is indeed peculiar; although it has ballistic inserts inside, it’s noticeably lighter than body armor of the same level, enhancing flexibility, the internal cushioning layer is presumably redesigned too, my first shot hit Sasaki Nai’s abdomen directly, yet her actions were hardly affected."

"And that foam grenade, I’ve never seen such an uncanny thing in my life..."

Gao Bo followed the topic halfway, then noticed Shi Zhengmin and Zeng Dan looking over consecutively, remembering Zhang Wenjun’s warning, he wisely kept quiet.

Gu Ji pondered a bit.

"Gao Bo, later, have Lang Shaobo take you to the 7th Mobile Unit to borrow a set of professional breaching tools."

"Understood."

He naturally knew what Gu Ji meant.

At six in the evening, the group finished organizing their equipment, boarded a white van, and followed SAT’s assault vehicle towards the designated target point:

Located near Sangwuguo Town Road in Hachioji City, in the Tama Region.

This was already the third time the group came to the Tama Region, it was quite coincidental, all encounters with Liangben occurred here.

They arrived near Xiangwu Country Road before 7:00.

The vehicle was parked under a sycamore tree by the roadside, through the window, Gu Ji looked around, scrutinizing the surrounding architectural environment.

This was a small crossroads.

Because it’s not the city center of Hachioji City, there weren’t any tall buildings around; the tallest one was the five-story apartment building to the north left of the intersection.

Also sizing up the terrain were the SAT special police squad, the same team that had previously met them in the forest.

SAT’s combat capabilities are undoubtedly strong, in the event of a severe case, they often choose to suppress by force rather than engage in negotiations, hence they have ample real combat experience, far surpassing Japan’s Mobile Unit and Self-Defense Forces members; for Japan’s Self-Defense Forces are rather unique, somewhat like civil servants, but definitely not as accomplished as Sasa Kana’s S Special Operations Group or the Maritime Special Security Team, these special forces units.
