"Captain, most of the weapons used by these mercenaries should be weapons with 5.56 mm bullets, and they should all be standard weapons used by foreign armies! And the weapons they use are better than those used by our soldiers!" Jiang Chen, who picked up two bullets from the ground, walked in front of Yu Bohuang and said.

The jungle beneath their feet was littered with bullet casings that had been left on the ground. Although all the bullet casings look similar, when you pick them up, you will notice that there is a big difference.

Although the country of China is vast and rich, it has a lot of natural resources. However, Huaxia is still a country lacking copper, and the most important metal for making bullets is brass. It is precisely because of the lack of copper resources that the bullets made in Huaxia are generally painted steel and copper-clad steel bullets. In the former, after the steel shell is manufactured, the surface of the shell is covered with a paint film to protect the shell from rust. The latter is to press a very thin copper plate on both sides of the steel plate, and then make the bullet case, which is also to prevent rust, and these two methods are also to solve the copper material.

However, countries such as Europe and North America do not lack such resources, and most of the products they manufacture are brass shells, and brass shells also have the advantage of good processing performance.

And now the two bullet shells in Jiang Chen's hand, one is a painted bullet shell commonly used in Huaxia, and the thin layer of paint can be faintly seen on the outside of the shell, and the bullet case in the other hand is a brass shell!

Just by looking at it a few times, Jiang Chen knew that the caliber of this brass shell was 5.56 mm, which was also a NATO standard bullet. Most of the bullet models used in Huaxia are 5.8 mm.

"Are there any other situations besides these? Looking at the two bullet casings in Jiang Chen's hand, Yu Bohuang, whose tone was a little cold, asked. Judging from the battle scene, the battle that took place more than ten hours ago was extremely fierce, and this group of well-equipped and well-trained mercenaries of the Vicious Wolf Mercenary Regiment relied on their excellent weapons and equipment from the very beginning of the battle, as well as the strength of their own strength, so that the patrol force of a squad suffered heavy casualties.

"Report!" After Yu Bohuang just finished saying this, there was a sudden shouting not far away, accompanied by the barking of military dogs.

"It's a military dog, the military dog should have discovered something!" After hearing this voice, Yu Bohuang rushed directly in the direction where the voice came from.

Before the operation began, Yu Bohuang was like an armed police border guard who applied for a military dog and a military dog handler. Military dogs are tens of thousands of times more capable of recognizing scents than humans, and their hearing is also 16 times that of humans. After special training, military dogs are fully capable of tracking, identifying, guarding, guarding, patrolling, searching, communicating, carrying ammunition, detecting, and searching for drugs and explosives. And Yu Bohuang applied to his superiors for military dogs this time, hoping to help the members of the patrol team complete the task in the later operation process.

When he came to this jungle, Yu Bohuang ordered the trainer of the military dog to take the military dog around this jungle and nearby to see if he could find any clues, even the things left behind by the mercenaries of the Evil Wolf Mercenary Group.

Sure enough, the military dog, with a keen sense of smell, under the leadership of the trainer, found out about the situation not long after. When Yu Bohuang led people to the location of the military dog, he saw that the military dog's handler was holding a piece of cloth stained with blood in his hand.

"Chief!" When he saw Yu Bohuang, the trainer of the military dog handed Yu Bohuang what he found in his hand after saluting.

The piece of cloth stained with blood and dirt was no longer visible at this point, but since it was discovered by the military dogs, it was very likely that it was the stuff of those mercenaries.

"I know this thing!" At this time, Hou Youmin, who came from behind, said directly after seeing the things in Yu Bohuang's hand, and his tone was even more excited, "This is a headscarf worn on the head of a mercenary, and I clearly saw that the other party was wearing this on his head at that time." And in the later battle, when these mercenaries retreated, I hit him even more, but I didn't kill him, and finally let him escape!"

After Hou Youmin said this, Yu Bohuang, who completely unfolded this piece of cloth, only then did he vaguely see a little square scarf from it.

"Captain, if what Squad Leader Hou said is true. That person should have been shot, and directly used his own square towel to temporarily stop his wounds, and then discarded it here at will!" Looking at the blood-stained scarf, Jiang Chen, who was standing aside, said.

The military dog found the location of the scarf at a certain distance from the place where the battle took place. All these things can prove what Hou Youmin just said.

"Let the military dog lead the way and see where he can take us!" Yu Bohuang, who was talking, handed the scarf in his hand back to the military dog trainer.

The nodding trainer handed the square scarf in his hand to the military dog, and then kept saying, "Night rain, sniff, night rain, sniff!" The night rain in the handler's mouth was the name of the military dog.

After doing this, the military dog handler directly let go of the military dog, as if he had found something, and the military dog ran directly in one direction after his handler stood up. The handler who leads the military dog follows closely behind the military dog.

"The spearhead group, keep up with the military dogs and trainers, and it is extremely important to protect the lives of the two!" At the moment when the military dog and the trainer moved, Yu Bohuang, who was full of seriousness, immediately ordered.

The Nalan Army, who received the order, didn't say a word of nonsense, and took several members of his group and followed closely behind the military dogs and trainers.

"The rest of you, ready to fight at any time!" When Yu Bohuang gave the order, the team members who were still searching for clues in various places just now had already assembled, and they all stood behind Yu Bohuang.

After Yu Bohuang said this, Yu Bohuang, who was holding his weapon tightly, was the first to chase in the direction of the military dog, and the rest of the team members followed closely behind Yu Bohuang. A patrol team of more than a dozen members is like a group of wolves in the jungle, rushing towards the unknown distance.

Since more than a dozen hours have passed since the battle began, a long dark night has been included in these more than ten hours. In addition, this morning, there was a thick fog in the jungle, and to a large extent, the smell of these mercenaries that was originally left in the jungle dissipated a lot.

The military dog in charge of tracking would stop every once in a while, and then put his head down and sniffed on the ground, and the military dog handler who saw this scene was very aware of this situation. He will once again hand the square scarf belonging to the mercenary in his hand in front of the military dog, and after this excellent military dog reconfirms the taste, it will run in one direction again.

As a pioneer group to protect two comrades, because they are afraid that their unauthorized actions will interfere with the actions of the military dogs. Therefore, he followed the military dog from beginning to end, and did not dare to run in front of the military dog. However, all the members of the Elite Group were all vigilant, because now they wanted to find the traces of the Evil Wolf Mercenary Group as soon as possible, and the military dog under their feet would play a vital role.

As time passed, the patrol team members did not know how long they had been tracking, and when the sun gradually rose overhead, the police dog in charge of tracking finally stopped his steps. The military dog rushed directly to a raised dirt slope, and with his claws outstretched, he kept digging the small dirt slope in front of him.

"Alert!" After seeing the military dogs and trainers stopping, the Nalan army under an order quickly rushed around the military dogs and trainers with people and established a simple defensive circle

When the trainer of the military dog saw that the military dog was constantly digging the slope with his paws, the trainer, who also understood what was going on, also squatted down, took out a shovel, and began to dig the soil on the slope layer by layer.

"What's the situation?" Nalan Jun, who was holding his rifle in both hands, turned his head and looked at the military dogs and handlers who were digging behind him, and then asked.

"There's something down there!" The trainer, with his hands still on his feet, continued to push a spade of dirt aside.

"I see!" Hearing this, Nalan Jun turned his head, and while warning the two comrades-in-arms, he began to contact Yu Bohuang, who was still following behind.

At this time, when the military dog saw that his owner began to help him, the smart military dog still stood aside, continued to help the military dog handler, and pulled the soil on the dirt slope to the side layer by layer.

"Ding!"

Soon, with a crisp sound, the shovel in the hand of the military dog handler soon touched something metallic.

As he pushed the last shovel of dirt aside, the dog-handler saw a metal canned food box peeking out of the dirt.

"This is military canned food, and it is also canned food used by special forces of foreign armies, and ordinary sales channels can't buy this kind of thing at all!" When he heard the voice, Nalan Jun had already turned his head. And when he saw the military dog handler digging out a metal canned food box from the dirt, and when he saw the dense English letters on the outside of the canned food box, Nalan Jun, who quickly recognized this kind of thing, said directly.

When he had not yet joined the army, the Nalan Army, as a military fan, had learned from the Internet about the canned food that the special forces of the foreign army often carried when they were fighting, but the Nalan Army at that time did not have any channels to buy this kind of canned food.

When he was in the underworld, Nalan Jun had the opportunity to come into contact with this kind of canned food and tasted it many times. When he returned to China, Nalan Jun had never seen this kind of canned food again, after all, there was no channel for this kind of thing to circulate in the country.

But now, when the trainer of the military dog dug the canned box out of the mud, Nalan Jun still recognized such a thing at first sight!
