The Imperial Expeditionary Force on this planet was defeated and retreated under the ferocious offensive of the Federation army, and the rout went north, leaving only fifteen percent of the living force at most to retreat back to the glacier in the far north. Against this background, it should have been extremely easy for the new 17th Division to carry out the final finishing touches, but the facts dealt them a heavy blow head-on.

Under the cold and tenacious command of the old fox General Ambrey, the remnants of the Imperial Expeditionary Force silently turned to guerrilla warfare. Instead of crushing in despair, tens of thousands of Emperors, who knew they had no way out and were in a desperate situation, became more ruthless and cruel, not only to their enemies, but also to themselves, risking the cold and infesting the glaciers like night rats, looking for any opportunity to attack the forces of the Federation, completely disregarding their own lives.

This kind of suicide-like madness succeeded in dragging the New Seventeenth Division, the Iron Seventh Division, and other federal forces into a bloody quagmire, nay, a cold hell.

I don't know if it was before or after the start of the war, the Imperial Expeditionary Force dug countless deep pits covered with snow between the glaciers covering an area of about three million square kilometers, and at the same time sent countless melee hot squads to guard the side of the pit group.

No one knows how many Imperial soldiers have quietly frozen to death in the ice and snow in this crazy way of fighting. But for the federal forces, they only know that these snow pits, which have concealed their electronic surveillance, have buried countless federal mechs and heroic pilots...... Lieutenant Colonel Helei, commander of the 1st Regiment of the New 17th Division, threw the battle damage report on the snow with a gloomy face and walked towards the barracks of the regiment headquarters.

It has been two and a half months since his troops arrived in the combat area, but the removal of the remnants of the empire has not made much progress, those imperial people hiding in the glaciers, like dying beasts, stared coldly at the officers and soldiers of the Federation, ready to pounce and beg for a life and death, under this deadly tactics, in just ten days, a regiment lost six M52 mechs and two MX mechas.

He was also shocked by the ability of the Imperial Expeditionary Force Command to control the remnants of the soldiers in the glacial world, as well as the command ability of those Imperial colleagues.

At the beginning of the Federation's victorious military operation, it successfully lured out the main armored forces of the Planetary Northern Empire Expeditionary Force, and also learned the specific location of the fortifications under the glacier that the Imperial had built for decades...... In the end, the Federation Command discovered that the old general named Ambury had actually left a back hand, and there were still several large underground bases hidden in the glacier that the Federation had not mastered.

"Report to the division headquarters that if the mechanics can't come up with any good solutions, our department refuses to enter the mountain again. ”

Lieutenant Colonel Helley's eyes were sunken because of Lian Yu's troubles, and his eyes were glowing with coldness, and he said: "It is the duty of a soldier to obey orders, but it is not death to send him to death. As far as I know, Hua Xiaoji's mecha brigade has also temporarily stopped entering the mountain. ”

"The division headquarters has no plans to enter the mountains at the moment, but we should not ask for it ourselves. An officer said worriedly: "The Imperial people are really crazy, and it is clear that they will lose the war, why would they rather commit suicide than surrender? ”

"Surrender? In exchange for me, I have been away from home for so many years, in a desperate situation, and I don't want to be captured by the enemy, I would rather exchange my life for the other party's life in the end, but we are defending the Federation, what are they for?"

Hurley said coldly, and the picture that happened in his mind half a month ago, when a group entered the mountain to clear the attack, a Federation mecha fell into the deep pit in front of the snow forest, and before it had time to break the ice, it was besieged and attacked by hundreds of remnants of the Empire. Those remnants of the empire didn't care about the main force of the regiment behind the snow forest at all...... In the end, the hundreds of remnants of the Imperial army were all killed by a powerful fire, but the Federation mech that had fallen into the snow pit also exploded.

Exchanging the lives of a hundred warriors for a mech is very correct in terms of battlefield value, but even on a battlefield where human lives are as cheap as grass, Heray and the federal military simply cannot accept this conversion.

He couldn't understand why the remnants of the empire's single infantry uniforms were tattered and could not be kept warm, their faces were withered due to lack of nutrition, their skin was festering from the cold and festering, and their movements were somewhat unchanged, and they could become so swift in an instant when they finally charged, and their eyes shot a crazy look like a dying beast.

What kind of idea can make a group of invaders, a group of soldiers from the lower echelons of the empire, bullied by the aristocracy, guys without any moral support, completely ignore the terrible death, and behave so fanatically and terrifyingly?

At this moment, an engineer wrapped in cotton balls walked out of the side room of the regimental barracks, with an angry glint flashing in his glasses on the bridge of his frozen red nose, and shouted to Commander Heley: "Mr. Lieutenant Colonel, I hope you will retract your previous verbal attack on the mecha designer. ”

It was clear that Herre's angry roar in the snow had reached the engineer's ears. Herre gave him a faint look and ignored him.

The engineer stomped his foot and said, "The MX mecha was designed by Lieutenant Colonel Xu Le, if you want to scold him, it's best to scold him in person." ”

Captain Helei's face stiffened slightly, shrugged his shoulders, walked past this person, and said, "Although he is my instructor, he has to be scolded when he should be scolded. Your mission is to deal with the damn ice pits that are killing mechs right away. If this ridiculous state of bows and arrows shooting through the alloy baffle continues, I'm really worried that I and your Shell Engineering Department will become the biggest fools in the cosmic war. ”

"The additional high-frequency short-wave positioning technology, which is what you call the pit breaking technology, has been basically successful after getting the data from Lieutenant Colonel Xu Le, and after the debugging is completed, it will be installed on all the mechas. ”

Heray stopped suddenly, clenched his fists hard, and said in a deep voice, "Very good. ”

............ "There must be countless officers and pilots on this planet who are scolding us. But I must admit that when I was designing in Hong Kong, I really made a stupid mistake. According to the data calculation of the balancer, once X's mechanical leg falls into the pit, the sensor force falls and the feedback is transmitted back to the assembly, and the mecha system cannot make adaptive attitude adjustment in an instant, that is, it will step on it as soon as it is stepped on...... Can you believe it? Our proudest work is actually born with cerebellar hypoplasia. ”

In the cold ice and snow world, a federal force of nearly 100 people is moving forward silently, and the tracked ice-breaking armored vehicles specially developed for the snow are mixed with three of the Federation's latest MX mechas, all three of which are painted white, but I don't know why, the waists and abdomen of these three white MX mecha seem to be different from the general MX.

The white MX mech at the back seemed to have been damaged, lost power, and was barely driven forward by the tractor, and a voice sounded in the airtight and insulated cabin, and the words were filled with a certain self-deprecating annoyance.

"We are engineers, and this irresponsible self-reproach and self-destructive impulse makes no sense. In my opinion, there is nothing too big of a problem with the design of the MX, mainly caused by the special topography of the 5460 glacial belt. Those M52s were also stuck in the ice pit and couldn't stand up on their own, which shows that the senior engineers who designed the M series did not envision such an extreme environment, including your teacher, Professor Shen. ”

A woman's voice rang out from the cockpit, calm and imbued with the Engineer's characteristic homemade smell.

"Extreme environments? Combat mechs that are supposed to be able to adapt to the extreme low temperatures on the vacuum ore star and the absolute high temperature towards the star plane, but only to be trapped in an ice pit, do you think it makes sense?"

"There are many extremes, especially on the battlefield. In the far north of this planet, the sea dial rises too fast, whether it is the outer primeval forest or the sudden rise of the glacier area, which severely limits the passage options of the mecha, so that the Imperial can accurately set the location and depth of the pit through calculation. Crucially, all seem to underestimate the hard bottom of ice, even though it is supposed to be gentle water in itself. ”

The woman in the cockpit continued to say calmly: "At zero degrees, the hardness of ice is 1-2, at minus fifteen degrees, the hardness is 2-3, when it is minus forty degrees, the hardness is 4, and when it is minus fifty degrees, the hardness is 6, and in the glacier area where the Imperial people are hiding, the air temperature is minus thirty all year round, and the surface temperature is even lower, according to the monitoring data of these days, the temperature inside the glacier has already reached minus sixty degrees." ”

"The ice cube at low temperatures is harder than Huagangite and steel, and at this hardness, after the mecha mechanical leg sinks in, there is no way to break the ice on its own with power. The Empire had time to break the ice in advance with hot melting, but the mechs on the battlefield did not have such time. ”

"And don't you think the ice pits dug by the Imperials are very elaborately designed? The ice pits we looked at at at the beginning of the month were completely uniform in caliber and just right in depth. In particular, the forward slip angle of the ice pit is very beautifully designed. ”

"The mecha mechanical leg falls into the ice pit at this angle, and the knee joint hydraulics directly lose all effect, because there is no point of focus and there is no room for displacement...... The Imperials were able to immobilize a state-of-the-art MX mech using the simplest force calculations in classical physics, proving that the laws of classical physics, with their simplicity and beauty, are incomparable. ”

In the cockpit, Shang Qiu, a genius female engineer from the Guoke Engineering Department, looked at the light screen data in front of her, and said calmly, not glancing at Xu Le beside her at all.
