After discussing the two blasting canisters, they waited for a long time before they exploded, and they exploded one after another at intervals, and after discussion by the engineer platoon, He Jinhai finally figured out the source of the accident.

The problem is all in the length of the leads, the leads of the blasting canisters are installed by the soldiers themselves, there is no standard, the length is different, and the results of the two canisters are very long, so it leads to the blasting time is too long.

The root is still in the manufacturing, and the standard for the length of the lead is not given, and the soldiers are all in accordance with their own ideas, so that this result is achieved.

Practice is really important, Zhang Wei and they are a test explosion, it seems that there is no problem, but if this is done on the battlefield, it will be a big mess, these two blasters from the fire to the explosion of the time is more than 20 seconds, on the battlefield, the Japanese army is completely possible to take advantage of this time to throw the blaster back, this blaster is equivalent to sending it in vain.

However, the damage effect is still very satisfactory, half of the semi-hidden bunker that was blasted was blown down, half of the bunker's logs and structures were blown up by the blasting canister, all the sandbags around it were scattered, the opening was opened, and the bunker was in a mess.

Two 3.5-pound long blasting canisters are enough to take out a semi-concealed bunker of a civil structure.

After the first blasting was completed, in view of the various problems that arose in the test explosion, Zhang Wei ordered that in the future, the engineer platoon must manufacture the blasting barrel as standardized, and the length of the lead wire must be uniform, and the situation like today must not occur, and the gap time before the blasting must be controlled within twenty or twenty seconds, so as to prevent the Japanese army from throwing back.

With the lessons learned from the first test blasting, the rest went much smoother, and the squad leaders and deputy squad leaders of the engineer platoon took turns to go up to work.

The two-pound blasting cylinder to the concealed bunker blasting test, the three-five-kilogram blasting cylinder ground blasting test, and the two-pound blasting cylinder ground blasting experiment were carried out successively. and blasting experiments in trenches.

Ten 3.5-pound blasting cylinders and 10 two-pound blasting cylinders were emptied.

After the blasting is completed, the most valuable thing is the data collected by hand, and the final conclusion is that the use of 3.5 catties of blasting canisters, for the semi-concealed bunker of civil engineering structures, two can be completely killed, and with two catties of small blasting canisters, you will get more than three.

In the fortification blasting test, the lethality of a one-time explosion of a three-five-kilogram blasting cylinder can kill one and a half shifts, and the lethality of a two-kilogram blasting cylinder is much smaller.

Facts have proved that in large-scale offensive operations, the main thing should be to use 3.5 kg blasting canisters, which have a strong lethal ability against the infantry in the trenches, bunkers, and ordinary trench fortifications, while the 2 kg blasting canisters are much inferior.

But the victory is light weight, small size, and in an emergency, two kilograms can be thrown outside as a grenade.

In complex terrain, when the long blasting canister can not be sent, these two-kilogram blasting canisters can play a substitute role, if there is a positional battle with the Japanese army, close attack, these two-kilogram small blasting canisters are more useful than the three-and-a-half-kilogram large blasting canister, and can be used flexibly in the trenches.

Another function of the blasting canister, minesweeping, was not tested, and the teaching brigade did not have mines in its hands, nor did it have the ability to lay mines.

However, in a flat detonation, the killing area of a single 3.5-pound blasting canister can knock out a combat formation of one and a half squads.

The blasting lethality of the two-pound blasting canister is also quite good, and the coverage area is relatively large, and it is enough to open up a safe passage when it encounters a mine.

He Jinhai recorded the amount of blasting canister and the lethality ability, Zhang Wei and He Jinhai discussed, and thought that the production of the blasting canister was generally very successful, adding a weapon to the teaching brigade to kill the enemy, in addition to the discussion with He Jinhai, Zhang Wei and the two asked for opinions from the soldiers of the engineer platoon who made the blasting canister and used the blasting canister.

The soldiers of the engineer platoon may not understand high-level things, they have rich practical experience and are direct users, and the opinions and experiences they put forward are more useful for users on the battlefield.

These useful opinions are often beyond the imagination of officers like Zhang Wei.

A squad leader of the engineer platoon believed that the current blasting cylinder had the defect of not being waterproof and could not prevent moisture, and the sapper explosives were allocated with a layer of yellow waterproof paper in the box, which was spread under the explosives to prevent moisture.

This squad leader has been in the army for many years, and in a previous battle, the unit he was in was damp with mortar shells and grenades, which caused many mortar shells to be fired in, and many mortar shells could not be fired at all, and even if they were fired, there were many unexploded bombs, and the firepower decreased sharply.

After the damp grenade exploded, it was directly cut in half, and it had almost no lethal ability, and in the end, the troops suffered heavy losses and suffered heavy casualties.

So this squad leader is particularly sensitive to the problem of dampness of ammunition.

The batch of blasting canisters used by the teaching brigade for testing were directly put into contact with the steel pipe when the explosives were placed, and they were stuffed into it without treatment.

After being reminded by the squad leader, it was found that it was easy to affect the use effect due to humidity during storage, and the cavity between the explosives and the pipe wall was easy to enter the water and get wet.

The squad leader suggested that the waterproof paper in the explosives box should be disassembled, rolled into a cylinder with a plug, and spread into the steel pipe, and then filled the wall of the pipe with waterproof paper with explosives, so as to take measures to prevent moisture, and also make the inside of the seamless steel pipe tighter and the bulk explosives more tight.

Another private wanted to attach a wooden rod to the blaster, saying that it could shorten the penetration distance, and when hitting the bunker, the pole could be pierced into the bunker firing port, and it would also reduce the area of the bomb.

The opinions of these soldiers were very useful, Zhang Wei greatly praised them, and informed the engineer platoon to add food for three consecutive days to reward the sappers who had worked hard in the past few days, and the soldiers naturally cheered.

The opinions of the soldiers, Zhang Wei and He Jinhai recorded them one by one, these low-level officers and soldiers who fought on the front line and worked hard actually had many useful ideas, it depends on whether the officers can ask them and use them.

Give full play to the small wisdom of the soldiers, and the wisdom of the working people cannot be underestimated, and the same is true for the soldiers at the bottom.

The soldiers of the national army generally do whatever the commander says, but their subjective initiative is not good, basically they are soldiers and work hard for money.

Of course, now that the system has collapsed, not only do the soldiers have no money, but many do not even have enough to eat.

The officers did not attach importance to the soldiers, the two sides were almost disconnected, the following experience was difficult to convey, and the soldiers had to get by, which eventually led to the slow progress of the troops.

The engineer platoon came up with a lot of good ideas today, and Zhang Wei let out his words, as long as there are good ideas in the future, everyone can speak their minds freely, and as long as the ideas they say are useful, Zhang Wei will have a big reward.
