You were tasked with guarding the Sihang Warehouse, and you brought out a Tiger tank?

On the front lines in Montenegro, Liu Yongnian stood behind a bunker outside the command post, holding up binoculars and watching the massive offensive unfolding ahead.

The scale of the attack has been completely escalated.

It was no longer just Qi Liang's battalion probing alone; an entire infantry regiment of the First Guerrilla Division had arrived and launched a full-scale attack on the main position of Heishan at the foot of the mountain.

The air was filled with the pungent smell of gunpowder and the stench of blasted soil.

Liu Yongnian turned his head and looked at an open space behind the command post.

There, several 105mm mountain guns of the 1st Guerrilla Division's artillery regiment were being skillfully disassembled by the artillerymen.

The heavy cannon barrel, gun carriage, and shield were mounted on the backs of mules and horses.

The less heavy parts were tied together with thick hemp ropes by a dozen strong soldiers who, chanting in unison, dragged them up the mountain step by step.

Liu Yongnian couldn't help but walk over and reach out to touch the cold, thick cannon barrel.

The steel's texture gave this brigade commander, who came from an artillery background, a sudden chill.

"The caliber, the workmanship, the rifling..."

Liu Yongnian muttered to himself, his eyes filled with envy.

The entire Independent 45th Brigade didn't even have a single 75mm mountain gun, let alone such large-caliber heavy firepower.

Soon after, the mountain guns were painstakingly transported to a flat area halfway up the mountain and reassembled.

The gunners, shirtless and covered in sweat, skillfully adjusted the firing parameters.

"Scale 250, direction 0.5 to the left, load!"

At the gunner's command, the bright yellow high-explosive shell was pushed into the breech, and the breechblock made a crisp locking sound.

"put!"

The gunner pulled the firing cord sharply.

"Boom! Boom! Boom!"

Several 105mm mountain guns roared simultaneously.

Huge fireballs spewed from the cannons, causing the ground to tremble violently.

The shells flew over the ridge at a very high angle, accompanied by a sharp whistling sound.

A few seconds later, a muffled explosion came from behind the mountain.

Although Liu Yongnian could not see what was happening on the other side of the mountain, he could imagine it.

Those Japanese soldiers who thought they were absolutely safe hiding in the reverse slope positions were now being blown to pieces by these large-caliber high-explosive shells.

"Hey, look over there!"

The chief of staff pointed to a ravine on the right and shouted loudly.

Liu Yongnian raised his binoculars.

That was a heavy mortar position belonging to an infantry regiment.

Several 120mm heavy mortars have been set up.

The gunner was wearing headphones and communicating directly with the vanguard company at the front via radio.

"500 meters directly ahead, at grid number four-A on the map, a Japanese machine gun position and a Type 92 infantry gun have been spotted. Requesting suppressive fire!"

The slightly hoarse roar of the vanguard company commander came through the walkie-talkie, with dense gunfire in the background.

"Artillery platoon received, four corners - square A, three rapid fire rounds, prepare!"

The gunner repeated the coordinates and immediately issued the order to fire.

The loader picked up the mortar shell, which was as big as a small aerial bomb, and slid it into the muzzle.

"Thump! Thump! Thump!"

In less than a minute, more than a dozen heavy mortar shells were fired at the target area.

Liu Yongnian could see it clearly through the binoculars.

The power of a 120mm mortar shell is extremely astonishing.

The shell landed and directly blasted up a column of mud and water more than 20 meters high.

Several shells landed near the Japanese trenches, and the huge shockwave from the explosions instantly covered that area.

The Japanese machine guns, which had been spitting fire wildly, suddenly went silent.

The Type 92 infantry gun, hidden in the trench, was overturned by the blast wave, tumbling twice in the air like a toy before crashing heavily onto the rocks.

Broken machine gun parts and Japanese soldiers' corpses were blown into the air.

Liu Yongnian gasped, feeling a chill run down his spine.

He recalled the scenes of commanding the battle.

The entire brigade only had five 82mm mortars, which were treated like precious treasures.

If frontline soldiers encounter heavily fortified enemy positions and want to call in mortar support...

First, a messenger had to be sent back to the battalion headquarters, then the battalion headquarters would call the brigade headquarters, and then the brigade headquarters would issue an order to the artillery company.

This whole process is incredibly complicated.

And he was a company commander of the First Guerrilla Division.

You can call in 120mm heavy mortar support directly with a walkie-talkie.

And his aim was so accurate, and his reaction was so fast.

The battle was fought like a clash between armies from two different eras.

"Commander, look at the mountain over there!"

The chief of staff's voice rang out again, his tone filled with shock.

Liu Yongnian looked in the direction the chief of staff pointed.

On a hilltop to their left, the engineers of the 1st Guerrilla Division were working with great effort to disassemble two 88mm anti-aircraft guns and move them into the position.

This type of anti-aircraft gun, originally used to shoot down airplanes, is extremely heavy.

Even with the transport broken up, the anti-aircraft artillerymen and logistics personnel were exhausted.

But it was all worth it!

At this moment, the anti-aircraft guns were lowered to serve as direct firepower.

The gunner stood behind the huge square gun shield of the 88mm anti-aircraft gun, holding a long, rectangular synchrotron rangefinder in his hand.

"Direction 216, armor-piercing high-explosive shell loading, distance 2400, wind speed negligible!"

At the gunner's command, the gunners immediately turned the elevation and traverse mechanisms to begin aiming.

The target was an extremely well-hidden Japanese bunker on the opposite mountainside.

The bunker was in a very tricky position. Since the start of the war, it had been using overtaking firing tactics to suppress the attacking forces from a high vantage point.

Several soldiers of the Independent 45th Brigade died from the fire of that heavy machine gun.

Liu Yongnian stared at the 88mm anti-aircraft gun through his binoculars.

"Fire!"

"boom!"

A huge ball of orange-red flame suddenly spewed out from the muzzle of the cannon.

The shell left the barrel at an extremely high initial velocity, tracing an almost straight trajectory in the air.

The 88mm anti-aircraft gun, when fired horizontally, is practically a giant sniper rifle.

After several shots.

"boom!"

The Japanese bunker on the opposite mountainside was blown up.

The armor-piercing high-explosive shell, carrying terrifying kinetic energy, slammed directly into the front of the bunker.

The armor-piercing capability of the 88mm anti-aircraft gun is certainly not to be underestimated; the sturdy concrete shell of the Japanese bunkers was instantly pierced by it, as if it were made of paper.

Large chunks of concrete shot into the sky.

The Japanese Type 92 heavy machine gun, along with the gunner's body, was blown directly out of the bunker by the massive shockwave of the explosion.

The mangled corpse hung from a crooked tree on the edge of the cliff, swaying back and forth in the mountain wind.

Clean and efficient, without any unnecessary delays.

The suppression fire had just been completed when the infantry of the 1st Guerrilla Division began their charge.

Liu Yongnian noticed that these soldiers did not charge forward in dense skirmish lines with rifles like his Northwest Army soldiers.

They divided into combat teams, using the terrain for cover and taking turns leaping upwards.
