When Wu Ming heard this, he thought about it and nodded: "That's okay, but you must do a good job of air defense measures for the heavy artillery unit itself, according to the information we have, although the Japanese army in Shandong does not have much air power, it has to be defended."

Even, it is not necessary that the enemy may send air power from its Central China to reinforce the East China battlefield, so we have to be careful, your heavy artillery brigade is the ace strategic force of our dragon tooth column, if there is any mistake, then the loss will be great, and the commander will not slaughter me at that time! ”

After speaking, Wu Ming was a little relieved, and changed his mind: "In this way, I will send an anti-aircraft machine gun battalion of my air defense regiment to reinforce the front line to shoot devils' observation balloons, and your air defense regiment should not leave the protective range of the two heavy artillery regiments without authorization, and continue to provide air defense support for them!" ”

Ma Yunlong nodded and said, "Okay, listen to you, Master Wu!" ”

"That's right, the next thing you need is the 105mm howitzer of your heavy artillery brigade to sing the leading role, give the little devil something powerful!" Wu Ming said with a smile.

"Haha, this is natural, this 105mm caliber howitzer, one shell down, is a large crater of more than ten meters, my two heavy artillery regiments have more than 100 such guns, a salvo down, is hundreds of shells, the power is imaginable. This will definitely make the little devil unable to eat and walk around! Ma Yunlong laughed quite smugly.

After the three of them entered the headquarters, they talked about the old days while discussing, and the next one was all equipped with the 12th. The anti-aircraft battalion with 7mm caliber anti-aircraft machine guns set off from Qihe County and rushed to the front line.

By the time the air defense battalion arrived, the artillery positions of the 3rd Division Artillery Regiment had been bombarded by a series of shells from the devils, and they were forced to helpless, so the artillerymen quickly transferred the 75mm Krupp guns, which were not yet in the middle, and even the men and guns were hidden in the bunker fortifications dug in advance.

The position previously used to fire artillery had been covered several times by Japanese artillery shells, and the explosion was filled with smoke and dust, and the fire was everywhere, so naturally, the artillery bombardment of the Japanese positions on the opposite bank was stopped.

After suppressing the firepower of the artillery regiment, the devil received the support of the artillery wing from the city of Jinan, and the two artillery wings were divided into two routes, and continued to fire at the Longya Artillery Regiment all the way, and continued to suppress it.

Along the way, artillery positions were quickly constructed, and artillery strikes were carried out against the dragon's tooth sappers and infantry who were digging and building sortie positions.

At this moment, the air defense brigade quickly caught up, quietly bypassed the area covered by enemy artillery fire, and with the cover of the thick smoke and fire, approached the effective range of its own anti-aircraft machine guns.

In fact, at this time, in order to alleviate the interference of the smoke in the sky to their vision, coupled with the fact that their own artillery fire had successfully suppressed the artillery of the Dragon's Tooth Column on the opposite bank, the observation balloon of the devils had moved from the sky above their initial artillery position to the airspace above the bank of the Yellow River.

When the officers and men of the air defense battalion quietly deployed the anti-aircraft machine guns, they happened to aim at them, and with the order of an air defense battalion commander, dozens of German-style anti-aircraft machine guns opened fire one after another.

Da Da Da ...... In an instant, the gunfire rang out, and dazzling tongues of fire suddenly erupted from the muzzle of the gun, whistling and flying into the air.

The observation balloon has an Achilles' heel, that is, it can be described as moving at a turtle speed, even if it is a rifle bullet, as long as the range is enough and dense enough, it is enough to hit and destroy.

Because, as long as the umbrella cloth on it rots a small hole the size of a thumb, it is also fatal.

Not to mention, there are now dozens of anti-aircraft machine guns with a rate of fire of up to thousands of rounds per minute, and thousands of bullets, or even tens of thousands, of bullets are whizzing in an instant.

That is to be destroyed on the spot.

In fact, when at least hundreds of scorching high-powered anti-aircraft machine gun shells hit the canvas of the observation balloon, they left a dense hole on it, and the entire hot air balloon burst from the middle of the sphere due to the influence of the air flow and the weight of the observation basket below and the devil's observation hand inside, the radio station, and other equipment.

Then, it split in two, and the battered spherical canvas fluttered in the wind and disappeared in an instant, while the observation basket of the person standing below descended vertically.

In the process of descending, Rao was also covered by the ground Longya Air Defense Battalion with dense anti-aircraft machine gun fire, and several devil soldiers inside were beaten into blood sieves on the spot, and the entire observation basket was hit before it fell to the ground, and a violent explosion also occurred the moment it landed.

Not only were the bones of several devils inside, but the aftermath of the explosion also affected the Japanese puppet army on the ground position, causing them certain casualties.

The devil's observation balloon was shot down, and the artillery on its artillery position became blind again, and it could only be suppressed by repeated artillery bombardment by relying on the coordinates and directions provided by the observers before.

Naturally, it was impossible for the Dragon's Tooth Artillery Regiment to go to its previous position to be bombed, so it soon changed its position and built a new artillery position.

At the same time, the air defense regiment of the heavy artillery brigade is also in place, especially the 88mm anti-aircraft guns they are equipped with, which are enough to bring the surrounding airspace of more than ten kilometers into their fire strike range, and the anti-aircraft machine guns just form an anti-aircraft fire network with high and low distances.

The two 105mm medium howitzer regiments also deployed all their hundreds of howitzers, and as their observers provided the orientation and coordinates of the enemy's position, two 105mm howitzer regiments plus a 75mm howitzer regiment, a total of more than 100 artillery pieces, opened fire one after another.

In fact, with such a powerful scale of their artillery fire, they no longer need to know the exact coordinates of the opponent, they only need to know the general location of the opponent, and they can rely on the powerful range of firepower to carry out an effective firepower coverage strike on it.

Boom Boom Boom Boom ...... Boom Boom Boom! Soon, a series of earth-shattering and violent explosions came from the Japanese positions on the opposite bank, in fact, before the explosions came, the red lights that went straight into the sky had flashed one after another.

The violent explosion turned the entire Japanese army position into a human purgatory in an instant, with fires everywhere, countless devils, and puppet soldiers all blown up to a blur of flesh and blood, and stumps and broken arms raged everywhere.

And with the continuous extension of the artillery fire of the Dragon's Tooth Column, the Devil's artillery wing was also affected, and some howitzer shells fell into their positions, with huge destructive power, and the devil's artillery was destroyed in an instant, and the losses were heavy.
