Guan Yong's Army Aviation Regiment had only twenty armed helicopters, ten transport helicopters, and eight ground attack aircraft.
However, this short-term firepower strike capability is still quite powerful.
The loud explosion echoed directly within this relatively narrow defense line.
Some soldiers who did not have time to dodge were torn to pieces by the explosion. Some were killed by the shock wave even in the trenches because they were too close to the explosion.
Although they built positions, the terrain of the river valley and the fact that it was just spring made the area extremely cold.
It is extremely difficult to dig a position in this semi-frozen environment.
Li Xin's attack came too quickly, so the defensive positions were not well built.
This made this bombing more effective than expected.
There was widespread wailing on the bombed positions.
However, these positions are relatively small, and there may be only a few dozen people in one defensive position.
The bombing was just a lot of noise but little action. Compared to the twenty or thirty defensive positions built within a defense line, the bombing could only hit a part of the positions.
"Hurry up and rescue the wounded!!"
After the air strike stopped, the commander roared and the soldiers rushed out of the anti-artillery shelters to check on the wounded outside to see if they needed rescue.
The commander of the air defense force angrily punched the combined missile and artillery anti-aircraft vehicle beside him.
The enemy was too far away, the ground attack aircraft flew fast, and the armed helicopters were far away.
This time their air defenses were of no use at all.
On the other side, the garrison troops had just stopped their air strikes when their artillery pulled out cannons of various calibers again.
Several drones were hovering in the air, with fiber optic pods mounted underneath them, which could be used for reconnaissance even in such a complex electromagnetic environment.
The observers constantly observed the enemy's defensive positions through the drone's sighting equipment.
He reported each parameter to the artillery commander, and after calculation, the coordinates were distributed to small artillery positions.
"One test shot begins!"
Following the order from the artillery commander, the artilleryman next to a 152mm howitzer instantly pulled the cannon.
Not only howitzers, but also mortars of various calibers at each artillery position began test firing.
"Bang!!"
"Bang! Bang!"
After a series of crisp sounds, the shells appeared in the air again with a sharp sound that cut through the air.
In the enemy position, the soldiers who had just come out to pick up the bodies of their comrades or the wounded were once again shot in the head and fled.
"Six-round rapid fire!"
The observer shouted excitedly after seeing the effect of the artillery hit.
The next moment, the gunners at each artillery position, as if turning on the accelerator, stuffed shells into the gun barrels one after another.
“Boom!!”
After completing a round of firing, these artillerymen quickly moved their positions to prevent being caught up by the enemy's counterattack.
Moreover, not all of the garrison's artillery were firing. At least half of them were waiting, awaiting the enemy's artillery counterattack.
The soldiers of the 7th and 8th Brigades of the garrison were new recruits.
But every one of these officers is a veteran officer, and they are all elite soldiers selected from the army by Li Xin.
They understand things that the recruits don't understand.
After the artillery fire, the enemy will definitely launch a counterattack. Half of their artillery is prepared to attack the enemy's artillery.
Although this is a feint attack, who doesn't want to achieve more results?
In the Yanaka Valley was a motorized infantry brigade of the enemy's Dewan Technology, whose combat experience was decent.
Behind their position, the artillery position here quickly locked onto the attacking artillery position through artillery radar.
The officer roared loudly: "Hurry, hurry, I need the enemy's coordinates!"
The coordinates were reported one by one by the operator, and soon the artillerymen were controlling the cannon and adjusting the shooting parameters.
"Fire!"
"Show them some color!"
"Let this enemy know that we, Dewan Technology, are not to be trifled with!"
The commander roared loudly, and his soldiers fired silently.
"boom!"
The shells hit many positions that had just been fired, but most of the artillerymen had already run away carrying or pulling their guns after firing six rapid-fire rounds.
Most of the shells hit empty space. Only one or two artillery positions ran a little slowly and were caught up by the enemy's artillery fire, resulting in casualties.
However, as Dewan Technology's artillery counterattack began, the garrison's drones in the air quickly captured the enemy's firing position.
Inside the command vehicle, the drone pilot exclaimed joyfully, "Found it! We found the coordinates of the enemy artillery!"
"5-670-61..."
A series of digital coordinates were reported by the drone operator and quickly sent to the other half of the artillery positions that were not firing.
"You bunch of idiots, eat my cannonballs!"
The commander laughed and ordered his soldiers to start adjusting the shooting parameters.
“BOOM BOOM BOOM!!”
The next moment, the whistling sound of shells cutting through the air was heard again in the air.
The artillery positions of Dewan Technology that had just opened fire were directly blown into pieces.
With the guidance of aerial drones, these cannons can fire more accurately.
But soon, these drones were locked down by Dewan Technology's air defense forces.
On the combined missile and artillery anti-aircraft vehicle, a desktop-sized radar was constantly rotating, capturing several drone targets that were approaching in search of artillery fire.
The commander of the anti-aircraft vehicle yelled, "Quick, aim at the enemy drones, don't let them fly again!"
It is too extravagant to use anti-aircraft missiles to deal with drones. Rapid-fire anti-aircraft guns are the best.
"Ong!"
“Thump, thump, thump!”
The revolver rapid-fire anti-aircraft gun quickly locked onto the drone in the air with the help of radar.
20mm caliber shells were densely sprayed towards the drones in the air.
These shells are equipped with delayed fuses and do not even need to hit the drones. As long as they explode near the drones, the fragments and shock waves can destroy them.
The drones equipped with fiber optic pods also lost a lot of flexibility and were basically wiped out by this round of enemy anti-aircraft firepower.
"call!"
A drone pilot let out a breath and angrily took off the controller on his head.
Apparently, their drones had all been destroyed.
This type of enemy air defense vehicle is not very effective against fixed-wing fighter jets, but it is extremely effective against slow-flying helicopters and drones.
