The fire of the three heavy machine guns also continued, so that the Soviet soldiers who were still charging in front of them suddenly all lay on the ground, bowed and carefully hid in the anticline of the hill, without the heroic appearance of shouting Ula to charge at that time. However, they did not sit still, and even the Soviets set up their heavy machine guns and mortars to bombard and suppress fire in the direction of the defensive pillbox, in order to try to make the three heavy machine guns inside the defensive pillbox, even if it was a moment!

A well-built defensive bunker with excellent firepower will be a nightmare for any infantry unit. Especially the defensive bunkers built in the mountains, without professional anti-pillbox weapons, plus a certain number of sacrifices, can not have any threatening effect on the bunker at all. In the current world, unless they go around to the entrance and exit behind the bunker to completely solve this strong fortification, no matter how many of them are, they will only be sent to death.

They can think of this solution, or the only way to deal with bunkers in this world at the moment. But these Soviet soldiers would never have imagined that Liszt did not leave any holes on the surface of this defensive bunker, because just three meters underground, there were still marines dragging pulleys and transporting ammunition quickly, and they completely relied on the narrow pipes for entry and exit and ammunition consumption and replenishment.

The originally huge elite infantry of the Soviet army has also been quickly divided into three groups, and the left and right sides have even deliberately allocated T55 medium tanks, increased the throttle to keep up with the footsteps of the hundreds of infantry, and rushed along the ups and downs of the mountain range towards both sides of the defensive pillboxes at the front. However, the faces of these Soviet soldiers were solemn and resentful, and the AKM assault rifles in their hands were quite wanton and disorderly to fire a few rounds at the defensive bunker, but they had no idea where the bullets had flew.

Rather than fighting back, they were more worried about their own hearts, and any light infantry unit attacking a well-fortified pillbox would be a definite death. Even with the help of tanks behind them, they still subconsciously quickened their pace, compared to the front of the bunker that did not dare to attack head-on, the entrances and exits on the side and rear were the only comfort in their hearts. As the elite infantry of the Soviet army, they believed that as long as they were close to the defensive bunker, they could cooperate with each other to make all the Americans inside die quite miserably!

"All the same, all the same—"

But just as the Soviet infantry on both sides bent forward and strode forward, the dull sound of hammering also cracked their eardrums, and with the shining of the metal-like bullets, the violent metal frenzy had been surging over, and the flesh and blood were only left in the rage, as well as the corpses of Soviet soldiers with wide eyes and faces full of disbelief.

Because in the eyes of everyone, they had bypassed the front of the frontmost defensive bunker, and just when the side wanted to outflank it, on the hill more than 800 meters away, the M2 Browning heavy machine gun unique to the American Federation reappeared there, and in that small and narrow shooting hole, it poured deadly fire on them, and at the same time made their originally high morale drop to freezing point in an instant, and at the same time made them want to continue to move forward, all covering their heads to face the flying dirt and anytime that were hit by bullets. Just lying on the ground and not moving.

The defensive bunkers around the cave base are distributed in a very regular manner, which is like a hexagonal diamond shape formed by the corners of two squares after discussion between Liszt and those Soviet experts. If this group of Soviets wants to attack, then they have to face the firepower of three defensive pillboxes, not to mention their hundreds of light infantry responsible for mountain operations, even if it is a plain on the frontal battlefield, in the face of the terrifying steel torrent of the Soviets, if the anti-tank firepower of the cave base is enough, they can grit their teeth and persevere!

The firepower that appeared in the four defensive bunkers on the west side had also resounded in this space, but inside the defensive bunkers at the top of Cave No. 5, Liszt's face was also extremely solemn, and he had certainly seen that the Soviet infantry had been thwarted in attack, and they were all curled up on the anti-slope and lying on the ground motionless. But his eyes also looked at the T55 medium tanks, like fearless steel monsters, still swaying left and right in the dense metal frenzy, the dense bullets hitting the cast turret, and also tightly touching countless tiny sparks and white spots, but they couldn't stop the tank's movement even a little.

Liszt knew that he lacked anti-tank weapons, and his brow furrowed when he looked up at the Soviet helicopters that were still circling back and forth in the sky, occasionally lowering their altitude and bombarding them with heavy machine guns and rockets. Not only anti-tank weapons, but even anti-aircraft weapons he still lacks, even if he now has more heavy machine guns in his hands, but he is mostly dealing with the infantry of the Soviets, facing the helicopters above the sky, he is not at all strong.

Although both anti-aircraft and anti-tank Javelin man-portable missiles have been devolved into defensive pillbox squads, it is not very threatening to hit a helicopter flying high altitude, or a tank that seems to be slow in the mountains but can actually accelerate at any time. On the contrary, if they leaked their anti-tank and anti-aircraft firepower too early, and were guarded against by those Soviet pilots, it would be even more difficult to hit those nimble helicopters and tanks.

The guidance effect of MANPADS is not high, not to mention independent discrimination, and it is not even a hand-controlled wire guide, and the hit rate is simply amazingly low. Even if a dozen MANPADS are launched, they are aimed at a stationary tank on flat ground, and as long as they are suddenly activated and evaded in a small area in a short period of time, it is possible that if they are lucky, all the dozen MANPADS will fail. And even if it is a wire-guided missile with better guidance effect, in the case of wind speed, distance and its own speed, without a high level of control technology, it will not be able to accurately hit the galloping tank, not to mention the Mi-24 Hind armed transport helicopter that can move up and down and left and right at an altitude of several hundred meters in the sky.

The M2 Browning heavy machine gun was still spewing muzzle flames in the narrow shooting holes, and the terrifying metal frenzy had begun to sweep the entire hillside, and even the crisp sound of the light machine gun had appeared in this space, forming a denser firepower, which was matched with each other to make the menacing Soviet soldiers unable to lift their heads. The T55 medium tanks, which were still moving forward, seemed to feel the intensity of the fire, and bombarded the bunker in front with the 100mm rifled gun, hoping to weaken the bunker's firepower.

The T55 tanks on the left and right had already begun to stop their advancing tracks, and casually fired a few shots at the defensive pillboxes in front of them, briefly pausing the heavy machine guns for more than ten seconds, and then in the dull sound of gunfire that reappeared, they began to retreat in the direction from which they came. The elite of the Soviet Union, who were originally accompanying the infantry, also got up on the ground with their bodies bowed in embarrassment, as if they had received some orders, and while casually sweeping the AKM assault rifles in their hands, they slowly retreated with the tank.

But in an instant, the firepower in the defensive bunker was almost all opened, and the M2 Browning heavy machine gun and the M249 light machine gun fired at each other, and one after another streamers appeared, and the sudden burst of fire made the Soviet soldiers who were caught off guard be swept down more than 20 people in an instant like cutting leeks. At this time, the T55 tank also seemed to sense something, and hurriedly retreated backwards one by one, ignoring even the Soviet infantry accompanying them, and just quickly retreated towards the anticline of the hill behind them.

However, in the complex mountain environment, the T55 tank can only perform a simple tactical attack, and once it encounters a difficult situation and wants to retreat or turn the body, it is simply more difficult. Even if the top of the hill and the slope to the west are relatively gentle, and the drivers of those T55 tanks have received orders from their superiors to quickly retreat to the rear, the heavy turret moves slowly, trying to grasp the balance of the body backwards, but there is still a T55 tank because when passing by a raised mountain beam, the whole body lost its balance and overturned on the top of the mountain, stuck on the raised mountain beam and could not move.

The rollover of this T55 tank was insignificant, but for the three tanks behind him who had not yet retreated, it just blocked their retreat route. The tank in reverse gear could not turn its tracks around the tank like flat ground on this mountain beam, and could only shake back and forth anxiously, but there was no good way. Even the accompanying infantry came to the side of the overturned tank, and before they could get a hand, the strafing fire from the defensive pillboxes re-attacked them and made them lie on the ground or behind the tank, and they did not dare to move again.

But a Soviet soldier lying not far from the tank just wanted to grit his teeth and lift his AKM assault rifle and shoot forward to counterattack, but his ears moved slightly. A strange sound appeared in his ears, so that he couldn't help but tilt his head slightly, but he suddenly found that there were a few more black shadows in the sky at some point, and at the same time, a roar in his ears instantly spread through his head, making his eyes a little more frightened.
