Autumn nights can be a bit chilly. Even in the trenches of Yan Kingdom, there were not many sentinels on duty. The Yan army has become a majority of recruits. The army of veteran lazy soldiers. Such an army has only a small amount of combat effectiveness.

"They're cold." A Yan sentry raised the collar of his coat to keep warm. The rifle slumped over the shoulder, and the whole thing looked like it had no combat effectiveness. The war dragged on for a long time, and the war situation entered a stalemate, leaving the soldiers at the bottom in a state of passive and tired war-weariness.

"Slow down." A heavily armed Qi commando carefully grabbed a piece of barbed wire. A commando came up from his side and carefully took off the canned food box. The first commando then used a wire cutter to cut the wire, after cutting it from the bottom. Carefully open a small hole that can be crossed through a person. After the first place is crossed. Second place was also passed.

And in the entire crossfire no man's land, there are many such barbed wire. Commandos had to climb all the way through such barbed wire positions. Although the Qin State could produce infantry mines in large quantities, such mines were not equipped for the Yan army. The reason for this is that Yan Guo does not consider the procurement of grenades and mines necessary. Especially grenades. At the time, the grenade had a safe reaction time of up to four to five seconds, which often caused an embarrassing situation when used repeatedly. And the Yan military believes that if this weapon is thrown over, it will also be thrown back by the other party. For this reason, Yan Jun believes that it is completely unnecessary to equip such weapons. If it is equipped, it is equivalent to equipping the opponent with this lethal weapon. Similarly, for landmines, Yan Jun considers this kind of "dead thing" buried in the ground. "It will be used by the other party. Because he is buried there and does not move, once he is opened by the other party and re-buried, he does not know. It's still going to blow up your own people. It is this unrealistic and conservative idea that makes Yanguo's military equipment stand still. The upper echelons of the Yan Kingdom, especially the beginning of Yan Wangxi, were very obsessed with the luxury goods of the Qin State.

On the contrary, the state of Qi began to realize the importance of weapons after being killed by the advanced military weapons of the other side. They continued to introduce and imitate various weapons, which slowly caught up in the stalemate phase.

The commandos who climbed over the barbed wire carefully poked their heads out to check the situation in the trenches of the Yan army. If the vigilance is lax, then they will choose to use it as a breakthrough. And the vigilance of the Yan army has always been lax. This is also one of the main reasons why the commandos of the Qi army frequently succeeded.

"Poof." A Qi short sword pierced into the heart of the Yan army's sentry. A member of the Qi State Commando suddenly covered his mouth and nose from behind, and then quickly assassinated him. Another trick is to wipe the neck. However, in order to achieve the effect of one hit, this extremely vicious trick is often used.

"Snort." Blood spurted from the heart. When the Qi State commando pulled out his short sword, the sound of blood was a little scary.

"Hurry up." When attacking the sentinels. The other commandos will quickly enter the trench from this breach. Then their military operations were carried out along the trenches.

"It's cold. this day. A soldier of the Yan Army, who had risen at night, came out of a dug rest hole wrapped in an overcoat. As soon as he came out, he hadn't reacted to what was going on. He was covered by the commandos, and then he felt a sharp pain, and then he lost consciousness.

One commando quickly moved the body away, while another approached the entrance, carefully squinting inside.

The observing commando held out three fingers. Signaling that there were three people.

The back nodded to sign. Then the first place quickly entered, and the next one followed. The three were all men who had been ordered to be on duty, the same as the one who had risen at night. They were all on duty to keep vigil according to the regulations, but all four of them deserted. They all went to sleep. But this sleep passed forever. Soon, they died in their sleep. The vigilance system of the Yan army can play a certain role in vigilance. But if the soldiers are slacking off on all fronts, then it will not play any role at all.

This is how the Qi commandos succeeded, and then they began to develop towards other communication routes. That was the channel for the rest of the large forces in the rear and the area of operation on the front.

"Who? Hold it! "An outrage has been spotted by a guard post.

The assault team immediately stopped advancing.

"Bang." A gunshot broke the silence of the night.

"Bang. Bang. "Two gunshots in a row. The commandos had to shoot back. But it was not accurate, and the continuous assault made the Yan army also understand that the weapons in their hands were much lower than the opponent's pistol shots in terms of continuous shooting.

"Attack from the flanks. Hurry up. A commander-like man ordered. The two assault teams then crossed the trenches and attacked the opponent from the flank passage.

"Bulging." A burst of machine guns rang out. One of the two commandos who had just jumped out of the trench was knocked to the ground. The bullets then came in a continuous row. A commando sticks his head out to check the situation. That's when the commandos saw the last thing they wanted to see.

"It's not good, the Yan army has built a bunker on the opposite slope, and there seems to be a revolver machine gun in it." The commando reported.

"Whoosh." Bullets began to whizz over their heads. In the face of more and more frequent attacks by Qi commandos, the Yan army was not passively beaten. They also have to take some measures to suppress their opponents. The machine gun bunker is the reference given by the Qin Army Observation Group.

Qi commandos often choose some communication trenches to attack when attacking. Because this is one of the points that must be snatched to further expand the victory. Another important reason is that starting the attack from the communication trench can effectively avoid the fire attack of the Yan army. In particular, the attack of artillery grenades.

The advice given by the Qin Army Observation Group was to deliberately build some bunkers near some communication trenches. These bunkers blocked these communication trenches with machine guns. And machine gun bunker points are often deliberately raised in height. With the accumulation of dirt is specially used to create a slope, and then use this height difference to form a small commanding height. Then set the machine gun position. In this way, it can effectively strike and suppress the opponent and further expand the results. In order to achieve the commanding heights to control the overall effect. The Qin Army Observation Group also gave such a wonderful trick, that is, camouflage. Use clever camouflage to achieve its amazing killing effect.

The appearance of the machine-gun bunker put the Qi commandos in a dilemma. However, this has happened before. This is just an exchange between several commando commanders. But this is when it comes in handy.
