A one-meter-diameter round-headed missile slowly protruded upwards from the inside of the mecha combat vehicle for some distance.

A few seconds later, a burst of fire suddenly erupted from both sides of the vehicle, and the missile instantly took off from the vehicle.

The missile climbed until tens of seconds later it entered the planet's low-Earth orbit.

At this time, there were already dozens of the same missiles floating in orbit in space.

When the missile's tail thrusters are closed, they begin to eject gas around their bodies, adjusting the missile's posture to the ground with the warhead.

Immediately afterwards, the thrusters in the tail of these missiles ignited again, and these missiles were instantly accelerated to sub-light speed and rushed towards the ground.

As soon as they passed through the atmosphere, the fairings at the heads of these missiles exploded and were thrown backwards, revealing 36 nuclear warheads densely bundled inside.

When the missiles rushed into a low altitude and were about to reach the enemy's air defense range, these sub-warheads suddenly broke free and sprinkled to the ground like scattered flowers.

A total of sixty ballistic missiles launched by imperial forces carried more than two thousand nuclear warheads.

These nuclear warheads fell towards the encirclement of tens of thousands of square kilometers where the Imperial landing force was located.

And just as the interceptor beam of the Spiral Federation was about to be launched, the main body of the missile, which had already missed the warhead, suddenly turned into a small sun and shot out a dazzling light in all directions.

At this moment, all the optical scanning equipment on the battlefield failed, and at the same time, the electromagnetic waves released by the missile, which were invisible to the naked eye, also interfered with the radar of the interception equipment.

When the light cleared and the soldiers of the Spiral Federation were about to intercept the warheads, they were horrified to find that the warheads had flown in front of them.

In mid-air, these 2,000 nuclear warheads detonated instantly, and 2,000 small suns appeared in the sky in an instant.

Immediately afterward, two thousand shockwaves instantly enveloped the entire defense line of the Spiral Federation.

The air propelled by the explosion of the nuclear bomb once again formed a second shock wave, which lifted all the armored vehicles and fortifications on the defensive line that were not destroyed by the energy.

Regardless of the nuclear warheads launched by the Empire, each of them is the size of a fist, but each of them has a power of tens of millions of tons of TNT equivalent.

And the reason why antimatter is not used is because the cost of antimatter is too high, and the ground forces are not worth using such expensive weapons, and nuclear weapons are also extremely powerful in planetary ground battles, plus the current technology nuclear weapons are extremely cheap to produce ....

When the smoke and dust on the battlefield cleared, the defensive positions of the Spiral Federation opposite the Imperial ground forces had been completely overturned.

Although it seems to be terrifying, it only has a lethal effect on the opposing infantry.

The armored vehicles and tanks that had been lifted out of the air gently turned themselves over with the support of their robotic arms on the ground.

The armor and shields of ground units of the same level as the Empire can no longer be wiped out by nuclear weapons.

The shock wave generated by a nuclear weapon can be lethal to soldiers who are only equipped with power armor.

The armored vehicles and tanks that were lifted out were only slightly damaged, and the elimination of these heavy targets had to keep them right in the center of the nuclear explosion.

However, the target of the Empire's nuclear weapons was not them, and the target of the Empire's nuclear weapons was the heavy artillery that the enemy had just exposed!

These bombs appear to have been falling aimlessly, but they were actually detonated above the Spiral Federation heavy artillery position.

And the positions where a large number of heavy artillery pieces were once deployed are now only a large pit.

"Assault of the whole army!" After seeing a message popping up on the screen, a sneer appeared on the corner of the Imperial Clone Legion's mouth, and he gave the order to surprise the entire army.

The Imperial mechcha chariot, which had inserted its mechanical legs into the dirt, immediately stood up and rushed towards the enemy's defenses.

The clone soldiers who were hiding under the chariot also stood up and followed behind the mecha chariot with their weapons.

At this time, the Spiral Federation defense line had not yet been restored, and although the nuclear explosion just now did not destroy many of their heavy armored units, their infantry did lose eighty percent.

The remaining 20 percent were also wounded, so they had to send their heavy armored units to the line alone, while the light infantry had to wait for the rear to be replenished.

But taking advantage of this gap, the troops of the empire rushed up.

The four main guns on the mecha fighting vehicle fired wildly at the spiral Federation tanks and armored vehicles on the defensive line.

Tanks and armored vehicles were pierced by Imperial artillery, turning into a twisted and burning mass of scrap metal.

At this time, the disadvantage of losing light infantry was revealed, due to the limited firepower of the tanks and armored vehicles of the Spiral Federation, they could only deal with the Empire's mecha fighting vehicles, and the Clone Soldiers of the Empire could not stop their power.

The Empire's clone soldiers are extremely scattered, and they are constantly crawling forward in serpentine trajectories, not to mention crawling, but with the help of power armor, they are enough to catch up with the speed of normal people!

This makes it extremely difficult to suppress the heavy machine guns on the Spiral Imperial armored vehicles and tanks, after all, the opponent is too scattered, and the heavy machine guns are not as good as the rifles in the hands of the infantry at this time.

At this moment, the infantry in the rear of the Spiral Federation finally caught up, and millions of soldiers with rifles and power armor ran through the craters created by the nuclear bomb, rushing past the burning wreckage towards the front line.

But just when the Spiral Federation thought their defenses were secured, they suddenly felt the sun disappear and the entire land was shrouded in shadows.

When they looked up in amazement, they saw that the 20,000 warships that had left in the sky had returned to the battlefield again.

The ships slowly mobilized the secondary guns at the bottom of the battleships to aim at the running soldiers on the ground.

Bang bang, tens of thousands of loud noises rang out continuously, and then bursts of "mushroom clouds" rose on the ground.

The Spiral Alliance soldiers who were running were directly sent into the sky by these shells, and the stumps flew all over the sky.

The guns on these warships are not comparable to ground weapons, and the lethality of a shell from a random secondary gun can make there be no living mouth within a radius of hundreds of meters, even when wearing power armor!

Two salvos of millions of secondary guns on 20,000 warships wiped out all the infantry sent to the front by the Spiral Federation!

The secondary guns then aimed their guns at the armored vehicles and tanks of the Spiral Federation in front of the defensive line.

At this time, the soldiers of the Spiral Federation really understood what the textbook meant when they said not to fight without losing control of the orbit.

In the face of these space warships, the troops on the ground are like toys to be ravaged!
