Due to the lack of troops, they quickly abandoned the control room they had just captured and concentrated their forces on the security center for a surprise attack. As expected, they were again met with stubborn resistance, but the enemy forces still could not find a solution to the jumping worms, and the artillery they were carrying never fired a single shot, and Lal suspected that the artillery should be some kind of powerful mortar, and in a narrow place like an underground facility, even a flat fire explosion could affect itself, causing the other side to dare not use it.

It could also be some kind of experimental weapon. Lal still doesn't know what kind of power source the other party is using, if it is a cold fusion reactor like them, packed in the backpack-like device on their backs, then it is really impossible to say how much impact this kind of artillery will have on the reactor, even if it is a cannon out and directly explodes on the spot Lal is not surprised.

They also encountered some automatic defenses, but they were all buried or suspended machine gun turrets, which caused them some trouble, but they didn't stop them. As Ral commanded his troops, he also assessed the unknown enemies he had encountered. Obviously, the level of the opponent's weapons and equipment is not particularly high, or it should be said that the opponent's individual armament is not strong enough to crush them, but it seems that the technology system is not the same. Their weapons still penetrate their armor, and their weapons pose little threat to their blast shields and cockroaches' biological carapaces.

These are almost certainly UED troops, but there is one thing that Lal does not understand. Although these ordinary soldiers had weapons on their arms, their hands were actually empty, and he did not understand why the other party had designed their armor in this way. There are also those guys with cannon barrels on their backs and heavy shields on their hands, which should have been designed to exist as support units, but unfortunately it may be that the current terrain has inhibited their play, and they can only exist as beaten units that attract firepower, and then be killed by jumping worms.

However, the shield was quite outrageous, they tried all kinds of methods but could not penetrate it, and even after the other party crouched down and unfurled the shield, they could not try to force it back away with an explosion, and the shield seemed to be rooted in the ground. Even if it was the shield of the Astral Unit, even if it couldn't break through the defense, the impact of the explosion would at least make them stumble or pause for a moment, but these people holding shields were completely undisturbed.

But they hadn't seen any other type of soldier except for these two soldiers, which made Ral feel very strange. However, considering that this is a secret research facility, the defense configuration is probably the security force, and the scarcity of troops is not unacceptable.

But as the war progressed, Rahr discovered a serious problem. The closer they got to the security center, the stronger the resistance they encountered, and the greater the human losses, and inevitably, the Hopper would die before the Marines connected to it died. However, due to the fact that the bug whisperer devices are all used together, the squad leader's command system can only see the information of the hopper at present, and cannot really communicate with it, resulting in the subsequent battles they are unable to command the hopper without their companions, and the hopper can only mechanically try to follow their pace to fight, trying to figure out their intentions.

It's not that the hoppers don't understand them. The hoppers are able to understand their commands, but the problem is that they are not used to charge head-on, and their camouflage gives them concealment to launch surprise attacks. In the presence of a master, the power armor can isolate the sound of commands, and they can freely give their own orders through the Worm Whisperer system, but without the owner, they will never be able to turn on the loudspeaker on the battlefield and shout at which enemy a certain jumping worm sneaks in front of him.

It can only be said that they are worthy of being an experimental army, and as soon as they enter the battlefield, there will be more moths. And they can't replenish their troops at all now, because to replenish new jumping worms, they need to pair up again, which is quite troublesome. Lal also noticed that although it has not yet happened, but there is still a potential problem, that is, after all, the jumping worm is the most basic combat unit of the alien insect, although it has a certain combat effectiveness, but the battlefield survivability is not much higher than that of the marines, once killed, the feelings that the marines have cultivated with great difficulty will all be burned, and they can only change to another jumping worm to start cultivating again, and the price is too high. However, if feelings are not cultivated, it will be difficult for the Marines and jumping insects who lack cooperation to play the maximum combat coordination efficiency.

The only solution he could think of was to collect and integrate the experience and skills of working with the Insects, like the textbooks of the Military Academy, and then teach everyone who needed them to learn, so that they could rely on the skills taught in the barracks and military academies instead of long-term emotional training in the same way that they did with the Armored Forces and the Aviation. In other words, humans need to adapt to the rhythm of the jumping insects, not jumping insects to adapt to humans. Because the biggest difference between humans and jumping worms is that jumping worms are produced by larval mutation, and all combat and killing skills are innate, which are derived from genetic instincts, and they can skillfully fight with a Marine at birth, while humans cannot. But human beings know how to learn, they can sum up experience, write textbooks for others to read and learn, while jumping insects cannot, they may be able to learn, but the skills they learn can neither be taught to other jumping insects, nor are they difficult to pass on to the next generation through genetic coding, not to mention that the death rate of the jumping insects themselves is too high, and the jumping insects that can survive many battles are almost non-existent, and they are even rarer than the marines.

But......

While Ral poked his head out and used the rifle in his hand to tilt the fire on the opposite side, he glanced slightly at the cockroaches and stinging snakes that were also pouring fire on the enemy.

There are also many kinds of insects, and it is estimated that some of the people who wrote the textbook have a headache......
