In the distant sky, a huge Boeing 747 aircraft is heading to the designated airspace, and in the nose of the aircraft there is a huge device, which is a laser emitter.

Began to receive messages from the front line, but did not notice the location of the light and heavy light levels that could not be attacked due to distance or other reasons, appeared in the computer in the aircraft control room, and then the plane began to fly in the surrounding airspace according to the predetermined route. The huge laser emitter was aimed at the beta in the distance, and as the various devices inside the airframe began to operate, the red laser was immediately aimed at the beta in the distance.

The soldiers on the ground saw a laser fall into the ground, which was thicker and less accurate than the beta light laser, but the power was against the light level, and even for small betas, the power of the laser was already able to make them turn into coke, and the irradiation time was extended, and even the heavy armor beta of the assault class would be killed.

The addition of laser weapons greatly encouraged the attack on the ground, especially in addition to the girl's two-way coalition army, the previous battle can be said to be too aggrieved.

It's still the traditional ground forces, tanks, armored vehicles, artillery and other aircraft and other weapons and some destroyers use artillery on the sea for fire support, although there are more people, but the fire support is not as good as the girl's road, and the power armor is not as large as the girl's road, after all, the power armor has only been studied for a few months, and the number of equipment and training time are big problems, except for a small number of soldiers who use power armor as an elite force, The other soldiers are armed with a variety of heavy weapons and beta combat.

The enemy is not human, and the weapons used have changed. Ordinary firearms are only useful for small betas, The beta of the combat vehicle level needs at least 12.7 mm caliber or more weapons to effectively kill, and the average soldier has no power armor and can't hold a heavy machine gun at all, and the heavy sniper rifle is not so practical on the battlefield, and finally it can be seen that many soldiers on the battlefield carry anti-tank missiles in addition to normal rifles, and there are Humvee-like vehicles that far exceed the normal amount of equipment, and the vehicles are equipped with heavy machine guns and grenade launchers, and even anti-tank missiles.

It's the same as the problem encountered by the girl.,The long-range artillery was intercepted by a large number of light-level targets.,Can only shoot at targets at close range.,Deeper targets are incapable.,The powerful impact of the assault level also made the coalition forces suffer.,If it weren't for the girl and Yamato to split a part of the firepower to support them.,Destroy the corpse of the assault class or the assault level directly.,I'm afraid the beta will rush into the human position a few times.。 And it is very tragic that on the two small hills, the heavy light level and the light level of the beta appeared on it, and the condescending light level and heavy light level directly strafed the defensive position of the human being, and for a time the human position was jumping.

In Cui Yifei's world, the light-level attack method has been understood, first lasting 2~3 seconds of low-power aiming, then shooting at full power, and destroying a tank in 6 seconds. But for the human tanks in this world, it doesn't take six seconds, and it will be destroyed in 3 seconds, and the tanks in Cui Yifei's world have a heavy reflective coating, which greatly strengthens the production capacity of the tank. And taking advantage of the sudden power of the light level, nearly hundreds of tanks were lost in a short period of time, and the defense line was precarious, if it were not for the decisive use of tactical nuclear bombs by the front-line commander to cover the subsequent attack of the beta and cover the position of the light class on the hill, I am afraid that the beta would have rushed into the front.

"It looks like things are getting better, and it's not a problem to break into the beta's lair." The girl has come to Yamato's side, relying on the washing of the ground with nuclear bombs and the cover of long-range lasers, a large number of beta light levels have been eliminated, and the human firepower has finally been brought into play, killing a large number of beta on the ground in one go, and the girl took the opportunity to catch a few assault-level betas, and then felt that the battle situation was unfavorable, beta retreated, retreated into the lair, and returned to the underground.

"Are you going to attack the beta's lair now, I remember the plan was like this." Yamato looks a little tired, unlike the girl, Yamato will consume the body after the battle, and after the high-intensity fire support, Yamato needs to rest.

"Tired?" The girl looked at Yamato with a little concern, and Yamato shook his head, but his stomach that began to rumble again betrayed Yamato, and Yamato blushed.

"Don't worry, your food is contracted by the United Nations." Covering his mouth and jokingly said to Yamato, "You go back and rest first, when you go underground to fight, your ability is not suitable." ”

"Well, then be careful." Yamato nodded, hugged Montana and returned to the battleship on the sea, while the girl commanded the surrounding troops to surround the buildings on the ground of the beta lair, and began to demolish the buildings on the ground of the beta to find an exit into the inside of the beta lair. And after about ten minutes, the coalition forces that followed the tail of the beta retreat also arrived.

In the tunnel combat mission, the main force is the military forces of various countries, and the troops of the girl need to rest and recuperate after high-intensity operations, and the troops of various countries have many reserve forces, and the 82nd Division of the Mi Army, which is parachuting in a transport plane, is one of the reserve forces.

Helped humans demolish the buildings on the ground of the beta lair, the huge above-ground structure is 50 meters high, and the underground part is about 350 meters in the detection, which is a typical beta level 2 nest. However, the underground tunnels are changing very quickly, expanding rapidly, and if time continues to drag on, maybe this lair will soon become a more advanced lair, so that the difficulty of human combat will be greatly increased.

Once in the lair, humans made a tentative attack on the lair underground, and the underground tunnels were wide and tall enough for human tanks to fight, and skilled helicopter pilots could even fly in helicopters. So after a short exchange, the Celestial Maozi coalition and the NATO coalition forces determined the main road of the nest according to the results of underground radar detection, and the two sides formed a coalition to enter the tunnel to test and eliminate part of the beta, but the battle in the tunnel is extremely difficult, and the complete darkness can barely be overcome for humans, and the searchlight is sent in, and it can also allow humans to see the surrounding situation clearly, but the complexity of the tunnel is far more complex than originally imagined.

The beta units on the ground that were tortured by human fire are comparable to monkeys in the tunnel, and various betas crawling on the walls of the tunnel may appear from anywhere, or even break through the wall directly from the other side of the tunnel that seems safe around to cut off the human troops, plus the heavy firepower cannot be sent down, air support is a joke, and the human race suffered heavy losses in the first tunnel operation, and soon withdrew the troops, and immediately began the planb battle plan, that is, the nuclear bomb cleaning plan.

Use nuclear bombs to constantly open the nest until the bottom of the nest is completely wiped out, even if there is any black technology, human beings don't want it, if you want black technology, you must have a life to use it, not to mention that there is a beta nest on the moon! When the beta was raging on the earth, the beta on the moon also launched an attack on humans, and the pressure on the moon was huge.
