Zhang Wei finished formulating the tactical training plan and called several squadron leaders, and after Zhang Wei formulated any resolutions and plans, he would let them see them, and Zhang Wei could not make decisions alone.

After reading the training plan, the three squadron leaders all put forward their opinions in a timely manner and helped Zhang Wei correct some details, while Mu Chao focused on the issue of air defense.

"Captain, I think our air defense awareness needs to be strengthened, this time in the Luoshan area of Xinyang, we were bombed by planes, and there were also planes bombed by little devils on the way back, in this regard, should we practice?" As soon as Mu Chao finished speaking, Qiu Wei and Zheng Yiqun both agreed.

"That's reasonable, the Japanese planes bombed too fiercely, and when we were in southern Henan, if we hadn't been guarding a secondary position, it is estimated that we would have been blown up by the Japanese planes long ago." Qiu Wei said, with a faint fear on his face.

What he said was that when he was in southern Henan, the preparatory battalion was deployed behind the Xinzhuang position garrisoned by the first army of the friendly army, and the Japanese army launched an air attack on the defender's position, and the Longshan position, the commanding heights of Xinzhuang and the left flank, was bombed very badly, and the Longshan position was bombed at that time, and the preparation battalion could see clearly from a few miles away.

"I was negligent, Mu Chao said it well." Zhang Wei patted his head, almost all his energy was focused on the infantry engagement, but he was negligent in air defense, this time in the Battle of Lanfeng, the bombardment suffered by the preparation battalion was mainly concentrated in the Battle of Xinyang, in fact, it was not miserable.

Several arson bombs fell on the position, plus they were strafed by two fighters.

The really miserable is the friendly army, Zhang Wei may be because he did not have a too painful experience of being bombed in the Battle of Lanfeng, so he forgot about this stubble when formulating the training plan, and now Mu Chao mentioned it, Zhang Wei felt that this was really a big problem, and the preparation battalion was not bombed much in the Battle of Lanfeng, but it may not be possible to teach the brigade whether it will be bombed in the future.

Air supremacy on the battlefield was controlled by the Japanese army for the vast majority of the time, and it was necessary to strengthen the awareness of air defense.

"Air defense, it's not like we don't have anti-aircraft weapons in our hands now, Li Shaoyan Squadron Leader's heavy machine gun has an anti-aircraft tripod, with this, we can fight small Japanese planes." Zheng Yiqun said that there were three heavy machine gun platoons in the heavy fire squadron of the teaching brigade.

Each of the nine imported Czech-made heavy machine guns that Zhang Wei pulled out of the equipment warehouse came with a tripod used for anti-aircraft shooting and a disc-shaped anti-aircraft sight when they were imported, which could be used for anti-aircraft shooting.

However, Li Shaoyan, the squadron leader of the heavy fire squadron, did not attend the meeting, he was a lieutenant, and the nature of the squadron leader of the heavy fire squadron was the same as that of the previous battalion heavy machine gun company commander, focusing on management, and in fact he Jinhai, the commander of the engineer platoon, was at the same level.

"It's not very useful, there are only nine machine guns in total, and we teach the brigade to have more than 800 people, and they can't protect it, and they can't form an air defense network." Mu Chao poured cold water on Zheng Yiqun, he has more combat experience, and Zheng Yiqun still looks a little tender sometimes.

This batch of Czech-made ZB37 heavy machine guns is indeed equipped with special anti-aircraft tripods and disc sights, but machine gun air defense is originally the next choice, belonging to the end of the air defense method, and the role of machine gun shooting to drive away and threaten is more significant than the actual killing.

Moreover, with only nine machine guns, it was not possible to provide a safe shelter net for the whole brigade, and it was also done before that the heavy machine guns were equipped with anti-aircraft tripods, and there were attempts before the war when the troops were armed according to German weapons.

At that time, the model unit of the National Army's readjustment division was the teaching corps, and each battalion of the teaching corps would be equipped with a heavy machine gun company and a mortar platoon, of which the heavy machine gun company was equipped with six civilian 24 heavy machine guns, two guns per platoon, and three platoons were programmed.

And one of the three platoons, two heavy machine guns were equipped with special anti-aircraft tripods and sights, which were also used in exercises and actual combat.

The conclusion is that it doesn't work at all.

Not to mention that two heavy machine guns equipped with anti-aircraft tripods do not form a dense firepower network at all, and the effect of anti-aircraft fire of heavy machine guns of 79 caliber is not satisfactory in itself, whether it is range or accuracy, the lethality is very average, and the national army does not have so many heavy pointed bullets and incendiary bombs to hit heavy machine guns.

The teaching brigade is now nine heavy machine guns with anti-aircraft tripods, and the air defense effect can only be said to be very limited, and even if all the nine heavy machine guns enter the anti-aircraft state, they cannot provide effective air defense cover for the whole brigade, and at most they can protect the strength of a squadron by driving away and firing.

It is inherently difficult to hit aircraft with small-caliber machine guns, and in the face of scattered Japanese troops, it is okay to find dead planes, but it is useless to fight large-scale bombing.

"The heavy firepower company will let them train in anti-aircraft shooting, and the problem of air defense must be strengthened by the brothers themselves, and they must learn to take the initiative to avoid air raids, and when they are deployed at the station, the sentries should pay attention to the sky, send people to fight air defense posts, and when building positions, they must do air defense fortifications, and these things must be summed up into air defense regulations and then added to the training plan."

"Okay, this thing should be done, not only the recruits, but also many veterans have not been subjected to many decent air raids, and they also have no air defense awareness in their minds, and they have never suffered losses or bombings." Qiu Wei added.

The veterans of the teaching brigade have good infantry combat ability, but they do not have much air defense awareness and "experience in being bombed"; in the battle near Xinyang, they have been subjected to small-scale bombing, and their understanding of aircraft and bombing may not be much better than those recruits who have been added later.

"What Qiu Wei said is that in fact, the bombing in southern Henan is a drizzle, and the bombing in Nanjing is called a serious air raid."

Zhang Wei recalled the air raid, the most ruthless air raid he suffered was actually in Nanjing, more than a year ago, it was dozens of bombers for dozens of minutes of carpet bombing, at that time if it were not for the good fortifications of Purple Mountain, it is estimated that there would have been no scum left in the bombing.

Air defense is divided into field air defense and air defense in important areas; air defense in key areas is needless to say, it is a fixed air defense network laid in large cities or strategic points, and this kind of air defense basically relies on heavy air defense weapons, such as various calibers, including large-caliber antiaircraft guns of more than 100 millimeters to fight, as well as a complete set of supporting facilities such as searchlights and observation stations.

Theoretically, field air defense also needs antiaircraft guns and antiaircraft machine guns to form a field air defense network, but the national army does not have this condition, and those antiaircraft guns and a small number of large-caliber antiaircraft machine guns cannot be distributed to the field troops at all.

Therefore, to teach the brigade the prevention and control measures is to strengthen the awareness of air defense, dig air defense stoves for cooking, and guide away the smoke generated during cooking.

When constructing fortifications, it is necessary to deliberately prepare for the prevention of air raids, to be on guard against the sky when stationed, and to fire empty guns when the situation is detected.
