At the moment, the guards' guns were collectively firing, and this was of course a once-in-a-lifetime opportunity, so whether it was a Humvee with bullet marks on its body or a person charging on foot, they all hurried forward, and everyone ran to the wall of the vault building in just one minute, leaning against the wall in a long way.

Most of them raised HK416 to prevent the guards on the roof of the building from poking their guns down, while three others quickly took off their backpacks, first took out a nail gun, and fired several shots at a window in the vault building, the concrete position of the window frame, to be precise.

"Bang, bang, bang......" Hou Tianming and the four shooters were still suppressing the guards on the roof of the building, but when Hou Tianming took the time to look behind him, he was vigilant to find that in the Fort Knox barracks not far away, someone had noticed the smoke from the explosion in the vault sentry box, and in a short period of time, a Humvee and an M113 armored car were turning around and driving this way.

"Speed up the efficiency, countless soldiers are coming, if we can't enter the building within 2 minutes, then we will all be torn to pieces by machine guns!" Immediately in the internal channel, Hou Tianming urged again, and after the people in front of him made nails on the concrete, they turned their heads and screwed palm-sized, round and thick metal rings on the steel nails.

"There's an explosion!" he hurriedly yelled, and the people gathered around the wall ran away, and then three seconds later, the metal rings that were fixed to the concrete exploded together, shattering a large piece of the solid window frame in an instant.

However, as the money bag of the United States, the building of this building is obviously stronger than expected, and after the window frames were blown up, one of Hou Tianming's subordinates ran up and smashed the iron fence outside the window with a heavy nail gun, only to find that the iron fence was not moving.

In the next minute, these personnel carried out a second and third round of directional blasting, and finally had to rely on the strong power of the broken Humvee, which reluctantly dragged the iron fence off the window frame and opened a breakthrough in the building with difficulty.

However, on this first level, Hou Tianming and the others wasted too much time, when the demolition personnel put explosives on the window glass, the Humvee and M113 armored vehicles that rushed to the door were less than 800 meters away from the barbed wire fence outside the vault, and this forced Hou Tianming to disperse his manpower and send two snipers to slow down the speed of the US military vehicles.

But who knew that the leaky house happened to rain overnight!

Just when Hou Tianming was halving the manpower of the guards, on the roof of the vault building, the remaining guards also found the military vehicles that came to support, and as a result, they took the opportunity to take the opportunity to take the lead, either strafing at Hou Tianming's side or simply stretching the M16A4 in his hand out of the daughter wall and firing at the people on the wall below.

The attackers below who had been waiting with their guns raised early in the morning naturally fired back unceremoniously, and in an instant, around the broken window, the two sides set off a new round of fierce firefights, and the gunshots rang out one after another.

"Bump, bump...... , Tutu ......"

Hou Tianming flicked the trigger, and then followed the HK416 optical scope, clearly saw the face of a vault guard, after being shot into a mess of rotten meat, suddenly a string of bullets fell coldly to Hou Tianming's side, and the dirt it lifted was more than half a meter high, so scared that Hou Tianming was a spirit, and instinctively turned his head to look behind him.

About 600 meters away on the grass, the US Humvee was in front and the M113 armored vehicle was behind, and the two military vehicles were rushing forward and using the 7.62 caliber machine guns on board to fire at the prostrate position of Hou Tianming.

Thankfully, the M113 was not loaded with a 30mm cannon or a 12.7 caliber heavy machine gun, it was just a command model with a 7.62 caliber general-purpose machine gun.

It's early in the morning, and the sights of both sides are clear, so when the personnel on the wall of the vault building, they finally blew open the damn window with explosives, the bullets fired by the U.S. Humvee almost hit the shoulder of one of Hou Tianming's snipers, causing him to curl up on the grass.

"Kill them. Finally, Hou Tianming urged calmly, and then when another sniper, he carried the unfolded M72 on his shoulder, the personnel on the wall of the vault building began to attack the inside of the vault, directly shooting at the vault guards who were guarding the window early.

Life and death are only on the front line, and now that the US military vehicles have been forced up, everyone at the scene knows very well what it means to not be able to enter the building, so under the strong desire to survive, smoke bombs, high-explosive grenades, and pearl grenades are smashed into the window.

"Bang, bang, bang......"

Then, in the dense sound of explosions, the vault guards guarding the room behind the window, several people turned into bloody corpses in an instant, and those who were lucky not to die in the explosion had to retreat in a hurry, but Hou Tianming's men set up a human ladder and rushed into the smoke-filled room.

"Head, let's go in, come on!" In the communication channel, the call of his subordinates was heard in an instant, but unfortunately Hou Tianming, who was on a cover mission, it was not easy for him to leave now, and he had to pass through the open area between the barbed wire fence and the vault building, and it would be 100% swept into a sieve by a general-purpose machine gun.

In this way, if Hou Tianming and the others want to move, they must first solve the big trouble in front of them.

Hundreds of meters away, the Humvee and the M113 were still strafing, and one of the shots was very coincidental and directly pierced the arm of Hou Tianming's subordinate who was about to launch a rocket, causing his body to fall over, and even the M72 on his shoulder rolled to the side.

So, Hou Tianming's body rolled dexterously on the grass, and after picking up the M72 left by his wounded men, the big lunge half-squatted on the grass, and instantly aimed at the Humvee about 400 meters away.

Although the firepower output level of the two vehicles is about the same, Hou Tianming still chose the target of his attack as the Humvee, because compared with the M113 armored car, the Humvee is obviously faster and thinner, and the more fatal it is, the more active it is to seek stability, rather than choosing a 50% chance to destroy the M113, it is better to choose a 95% chance to destroy the Humvee.

"Poof! Whoosh......"

Immediately, the muzzle of the M72 flashed, and the rocket was fired in an instant, and when Hou Tianming threw away the vacant launch tube in his hand, and his body immediately rolled sideways again to avoid the possible retaliatory strafing of the American army, the sniper who cooperated tacitly on the side also quickly changed his target, changed the muzzle of the gun from the Humvee to the exposed machine gunner on the M113 armored vehicle, and decisively killed it with one shot.

At this time, the Humvee that was hit by the rocket also exploded, and the men who had already rushed into the vault building threw a number of smoke bombs backhanded, quickly forming a smoke cover in front of the broken window.

Hou Tianming and the others, who temporarily eliminated the threat behind them, naturally turned their heads and rushed towards the direction of the vault building, but as soon as the remaining three people ran out for about 20 meters, the guards on the roof of the vault ran to make trouble again, and 3-4 M16A4 kept shooting at Hou Tianming and a few people.

In this way, in the fierce running, Hou Tianming, these special shooters, no matter how good their marksmanship is, it is impossible for them to continue to fire at the guards of the vault and achieve accurate firepower suppression under the condition of their own high-speed movement, so Hou Tianming can only take other methods, simply make an emergency stop in the running, squat down and then raise his gun and fire, and a shot hit the daughter wall next to a guard.

The guard who was firing was obviously startled, and when he was a little stunned, Hou Tianming, who was holding his breath and holding back his fierce heartbeat, then the second shot pierced the guard's forehead.

Next, the other two snipers also adopted different response strategies; one of them also followed Hou Tianming's example, and after rushing for more than ten or twenty meters, he stopped and fired two shots to cover Hou Tianming's sprint behind, while the other guy with an injured arm kept rushing with his head over, and in the process of running, he also ripped off a pearl from his ammunition vest, and decisively bit off the pull ring with his teeth.

But at this time, behind the three of them, the M113 armored car was still driven by strong horsepower, and the track "rattled and rattled", rushed straight up, and after passing over the wreckage of the previous Humvee, it left two deep crushing marks on the grass, and easily crashed through the barbed wire.

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

And under the cover of round after round, Hou Tianming and the three of them quickly came to the tattered window, and waited for the sniper who ran at the front, he raised his hand to throw the pearl grenade on the roof of the building, and after killing and injuring the vault guards with countless small steel balls, and driving them away, the three of them were ready to climb into the window one after another.

The men who entered the building first, they were lined up on both sides of the window at this time, and kept shooting at the M113 with the HK416 in their hands, and the front of the armored car was splashed with Mars, but unfortunately this could not stop the approach of the armored car, but one of the sturdy men, he reached out and dragged the snipers in one after another, and kept shouting: "Hurry, hurry!"

At this time, the M113, which is as powerful as a bull, has also chased behind Hou Tianming, if it weren't for the fact that the M113 was designed relatively early and there was no shooting hole installed on the body, the American soldiers in the carriage could kill Hou Tianming as long as they fired a few shots.
