Now that the reconnaissance equipment has gone down, those officers on the ground will naturally get together, and everyone will look at the pictures sent back by the drone camera at the same time; there will always be videos of interference with the crossway, and strive to prepare to see the situation inside the 1024 base and understand the enemy's reality.

This explosion, although the earth and rock layer of the cave collapsed a large area, but it was far from the extent of blocking the entire hole, so the drone, which was not much bigger than a human head, flew smoothly into the equipment area on the top floor of the base, which is the location where Lieutenant Marven led the people and the undead team to fight fiercely not long ago.

However, at this time, the undead team has already turned off all the lights on the top floor, so in this way, the US military commander and others above, they can only see a black scene on the screen, and the small lights on the drone illuminate the pitiful 1-2 meter range.

Corpses, blood, overturned tables and chairs, this place looks like a picture of a major war that has just been experienced, but other than these, the officers of the American army have not seen a single living thing.

"Let's go inside!" the commander instructed clearly, and the operator on the side naturally immediately carried out the order.

Who knew that 3-4 seconds later, the drone had just bypassed a pillar, and the soldier in charge of the operation was about to show according to the floor plan in his hand, when the remote control drone went to the corridor and elevator shaft to take a look, a black shadow flashed, and the drone was smashed to the ground by something, and the last frame of the picture that the officers saw above was that one foot stepped on the damaged body of the drone......

Although the eyes and ears of the reconnaissance were knocked out, the picture information just sent back by the drone has already conveyed a lot of information;

First of all, judging from the scene on the top floor of the base and under the cave, the garrisons of Base 1024 have resisted stubbornly, and the large bullet holes on the underground walls and multiple explosion marks can show this.

The second is the garrison of the 1024 base, they should have been completely wiped out, or all captured, otherwise the base will not become a dark state, because the dark state is only more beneficial to the attacking side, if the personnel inside the base are still resisting, then they will never turn off all the lights.

In addition, it is worth noting that the attack on the 1024 base this time should not be some stragglers, just look at the personnel who are waiting for them in the dark, and they also know how to stand guard near the main passage and decisively defeat the reconnaissance drone, which proves that they should be some elite veterans with good tactical literacy.

Figuring out these situations now will of course be of course very helpful for the next attack of the mysterious force, so the commander of the mysterious force immediately adjusted his strategy, and after 5 minutes, ordered the first round of tentative attacks!

Along the hole in the ground, two soldiers with bulletproof shields were first lowered, and after they established a foothold on the rubble and rubble in a dark environment, and sent a light signal to the ground, the six soldiers in chemical protection suits slid down one after another.

In the blink of an eye, as soon as their feet hit the ground, the group quickly held the HK416 assault rifle mounted on the laser sight, supported by two bulletproof shields, and began to look back and forth in the surrounding areas that could be used as cover, looking for traces of the enemy.

Those who dared to come down in the first wave were basically the most brave and experienced soldiers, and they had already been mentally prepared for a bloody battle, but who knew that the situation was the opposite, after they were on high alert for 3-4 seconds, there were no gunshots around, and even the sound of breathing could not be heard, everything was dead and silent, as if there were only a few of them here.

But anyway, it was a good thing that there were no bullets to greet him, but just as the group was about to disperse to defend themselves, in the corner of the dark hall, the wooden handle suddenly flashed out.

These well-equipped soldiers of the mysterious unit, all of whom wore night vision devices, naturally noticed the figure of the wooden handle instantly, but before they pointed the muzzle of the HK416 at the wooden handle, the wooden handle waved his arm and threw the last of his remaining homemade M24 over.

Immediately "Peng" with a loud bang, the long wooden handle grenade with lightning speed, directly in the middle of the soldiers, its strong explosive force, directly swept everything around, the US military just established this foothold, in an instant was the explosion clean pull-out, by the soldiers as a bulletproof shield to rely on, but also by the shock wave of the air wave to fly out of the distance.

"Group A, reply immediately! Do you need an attack?" At this time, hearing the sound of explosions from the ground, the commander of the mysterious unit finally couldn't hold back, he grabbed the walkie-talkie under his hand and asked, but unfortunately no one below could answer his call, because at this time, the first eight people had already been killed and wounded, and then there were two people, Mu Handle and Civil Engineering Expert, who were walking among the corpses of the soldiers, ready to give a shot to those who had not yet breathed.

"Damn, go down to Group B and support Group A. The commander, who had a bad premonition, immediately gave a new order, but when the soldiers of Group B, they had just thrown two smoke bombs into the hole, and at the same time, the soldiers of Group B also fastened the rope around their waists, but before they could slide down, the wooden handle below unexpectedly came to preemptively.

This time, he simply held the AR15 with the wooden handle, crouched directly under the hole in the ground, pointed the muzzle of the gun at the hole above his head, and fired in a small circle to fire at the soldiers who were about to slide down.

"Bumper, bumper, bumper......"

The bullets that flew up from below greatly surprised the soldiers on the ground, a mysterious soldier with a rope, after he was shot in the back continuously, he immediately screamed, slipped and fell into the hole, another soldier of the mysterious unit next to him reached out to pull him, but unfortunately he was a step too slow, and he could only watch his body disappear from the hole and fall hard.

After a second of consternation, the soldiers guarding near the entrance of the cave were all furious, and the companions who had just fallen were shot and fell again, and basically had no hope of survival, so they simply held M16A4 and HK416 and fired wildly into the cave.

As a result, the two sides fought one after another, and in the incessant gunfire, the wooden handle side took the lead, while the American soldiers relied on the large number of people to beat the despicable guy below into a hornet's nest with bullets.

"Tutu...... "In the middle of the shot, a string of bullets fell to the side of the wooden handle, but he was completely unmoved by the wooden handle, and continued to squat steadily in place, constantly firing at the head, almost every second, the muzzle of his gun was moving slightly, and the bullets were used to force the head of every exposed American soldier at the hole to retract again.

Soon, a second unlucky soldier appeared!

When a soldier of the Rapid Reaction Force, he was about to step forward and shoot a few shots at the bottom of the hole, his head had just poked out, and a bullet flying from below hit him in the eye socket by chance, so under the gaze of the soldiers around him, the first class soldier stiffened and fell headlong into the hole.

Seeing that his men and horses were damaged one after another, the commander of the mysterious unit, his face was no different from the bottom of the pot!

So far, the brigade has not even seen the face of the enemy, but there have been ten soldiers killed and wounded, which is a clear slap in the face for any commander, and the corners of the angry commander's mouth are trembling!

As a result, before the commander could speak, a non-commissioned officer beside him comprehended the intention and started the operation, and after rushing forward in a few steps, he desperately pulled out an M67, pulled off the pull ring and smashed down the hole in the ground.

On the other side, when the M67 grenade landed on the side of the wooden handle, it instantly scared the wooden handle enough, and he rolled backwards without hesitation, ready to roll out of the explosion range of the M67.

It's a pity that his movements are definitely not as agile as the young man, and it is estimated that it will be difficult for him to escape from the explosion before the grenade explodes.

So in an instant, when he was mentally prepared for the wooden handle, expecting that he would be seriously injured or even killed, the figure of the civil engineering expert flew over coldly, and at the same time he was holding a bulletproof shield that he had just picked up, and when he pounced on the wooden handle, he instantly protected the bodies of both with a bulletproof shield.

With the shaking of the ground and the attack of air waves, the M67 grenade exploded violently, and then the shock wave and sporadic shrapnel fell on the bulletproof shield together, and as a result, the bulletproof shield in his hand was lifted out again.

But in any case, this bulletproof shield finally saved the lives of the two of them, so after the explosion wave, the two old men ignored the feeling of tinnitus and dizziness, and supported each other and fled in the direction of the corridor.

However, immediately behind them, the second M67 grenade was thrown down, and after the "peng" exploded on the earth and rock, and before the two of them could run away, the angry group B people were killed one after another.

This time, the commander on the ground also saw the opportunity, and let the men and horses of Group B break through close to the wooden handle in the retreat, without giving the undead team time to rearrange their manpower, so that they can successfully gain a foothold, and in just two breaths, a total of 15 soldiers wearing chemical protective suits, a piece of white huhu spread out under the hole in the ground, and after quickly establishing a position, even the commander himself ran down, so that it was convenient to command the battle nearby.
