Long Jianguo took a breath and said: "The most important thing in this plan is time, the main cave is in the hands of the enemy, my troops are all acting in squads, we must seize the time to enter the main cave to drag the enemy, otherwise let the enemy enter the branch hole, and the trapped troops will be in danger." ”

"So what are you waiting for?" Bian Ge asked.

"I've finished giving the order, the troops are on the move." Long Jianguo said.

"Are you sure?"

"Nope." Long Jianguo told the truth, "It is not difficult to enter the main cave, the difficult thing is whether the trapped troops can hold on until the main force enters, and after entering the main cave, not only must they repel the enemy, but they may also have to clear the enemy in the branch hole...... The consequences are unimaginable. ”

"How many troops are you going to commit along the way?" Bian Ge asked.

"One or two companies, no matter how much it is, it won't be able to be used." Long Jianguo said, "Priority should be given to rescuing the lost troops, and those who can be contacted will see the degree of danger, and those who can save themselves will try to save themselves." ”

Bian Ge listened to it straightly, there are so many main caves and so many troops in the branches, and it is necessary to judge which troops are in danger and need to be rescued first, and which troops are in good condition to save themselves, just thinking about it can know how great the pressure of command is.

And everything is going well, if there is an accident in the middle, the rescued troops are not rescued, and even the rescue troops are also put in, and the rescue plan behind it will be ruined, and if Long Jianguo is not good, it will be a thankless result, and he will have to go to the military court when he returns to Earth.

At this time, Bian Ge had already led the second regiment through the giant ship and was heading towards the bottom floor, looking at the cave on the wall of the well, a thought suddenly popped up: "Old Dragon, I have an idea, you refer to it." ”

"What thoughts?"

"So, did the troops write down the location of all the caves when they entered the shaft?"

"Yes!"

"That's good." Bian Ge said, "I just came out of the giant ship, the giant ship is very tight, I think Wan Zhen can send troops into the giant ship again, find the location of the cave according to the previous records, blow up the shell from the giant ship, open the cave and pick up the trapped personnel!" ”

"Will it work?" Long Jianguo was very hesitant, "The plan is quite good, but the caves blocked by the giant ship are all on the support points, and there is no need to blow up the places where there are gaps, and the places without gaps are all support points, if the support points are blown up, what if the giant ship slides down again?" ”

"Wouldn't that be better? The giant ship fell down and gave up the place, whether it was blasting or digging, it was much more convenient than now! Bian Ge said, "It's better to simply blow up the support point and let the giant ship slide down!" ”

Long Jianguo said hesitantly: "It's easy to blow up the giant ship, but what if you slip for a while and get stuck?" When the time comes, those who should be rescued are not rescued, and those who are fine are trapped again, and they can't even muster the strength to save people! ”

"Then blow up the giant ship with a nuclear bomb!" Bian Ge gritted his teeth, "Directly blow up the giant ship, what do you say?" ”

"I reserve my opinion." Xiao Yuan said, "The diameter of the shaft is too small, and even the smallest nuclear bomb with the smallest yield is too powerful, which will definitely affect the shaft, and it will be troublesome if the strength of the shaft is damaged." ”

"I also think it's better to be cautious, although this method is simple and straightforward, but the consequences are unpredictable, and you can't mess around unless you have to." Long Jianguo said.

Two to one, Bian Ge sighed: "That's good, listen to you." ”

The three of them unanimously agreed and immediately acted according to the established plan, the first and second regiments blocked the passage under the shaft as quickly as possible, and the divisional troops attacked several branch holes near the giant ship under the command of Long Jianguo.

The attacking team soon encountered the enemy troops, and under Long Jianguo's orders, each advancing team concentrated a few machine guns to clear the way.

In order to counteract the recoil of the machine guns, the machine gunners who fired frantically had to be followed by several fighters, who pushed the backs of their comrades one by one, so as to ensure that the team moved forward quickly.

The barrel of the gun spun rapidly, the bullets were sprinkled at the enemy like money, and the dense rain of bullets filled the tunnels, giving the enemy no room to dodge at all, and any aristocratic army that encountered these teams would end up being beaten into a sieve by a torrential rain of bullets.

The military has long been equipped with 12.7mm armored rifles, and for a long time, whether it is against giant insects or against aliens, armored rifles have always been the main rifle of the military, but in addition to armored rifles, other weapons equipped by the troops are constantly changing.

In the early years, considering the convenience of logistics and the versatility of ammunition, the caliber of machine guns and sniper rifles was also 12.7 mm, and the ammunition for rifles, machine guns and sniper rifles was universal, but the performance in actual combat was not very good.

The 12.7 mm large-caliber sniper rifle is invincible against humans, but the aliens are tall and large and covered with a shell, unless they hit the vital point accurately, it is difficult to kill them with one hit, so the military replaced the original sniper rifle with a 20mm sniper gun, and strive to kill the enemy with one shot in wartime.

The 20 mm super large caliber gives the sniper super power, even if it fails to hit the vital point of the alien, it can kill the alien in a very short time.

Anyway, sniper rifles are precision firepower, and training a sniper consumes thousands of ammunition, but the ammunition consumed in actual combat is often only a few dozen or hundreds of rounds, and there is no pressure on ammunition.

Machine gunners, on the other hand, are based on suppressive firepower, and combat relies on fire density, non-precision fire.

However, the 12.7mm machine gun bullets were too large and heavy, and the machine gunner and the co-shooter could not carry many rounds of ammunition in total, so they did not dare to open the fire at all, otherwise they would run out of bullets in a short time.

If you have your own logistical support, it's fine, but if you go deep behind enemy lines, the machine gunner has to do everything possible to save bullets, and the result is that the machine gunner tries to shoot as short as possible, and the density of fire is about the same as that of an armored rifle, completely losing the tactical significance of suppressing firepower, and it is better to use an armored rifle directly.

To improve the situation, the military had to replace the armored machine gun with a 7.62 mm multi-barrel machine gun.

In terms of power, 7.62 mm is indeed far inferior to 12.7 mm, but it is not so bad that it cannot penetrate aliens, but it is just a matter of many fuselage guns.

Moreover, after changing the gun, the machine gunner carries four times as much ammunition as before, and in extreme cases it can even reach six to eight times, and can spread fire to the enemy to the fullest, and after discovering the enemy, it is often rained bullets that can leave more than a dozen transparent holes in the alien's body in the blink of an eye.

By making up for the lack of lethality in numbers, the deterrent power of medium-caliber machine guns against the enemy is much stronger than that of armored machine guns.

This is like the difference between a rifle and a shotgun, a rifle can indeed kill people, the amount is that a shotgun is full of blood holes when a shotgun hits it, and the psychological pressure is stronger than that of a rifle.
