The Research Institute of the Japanese Army Academy of Sciences had no choice but to reduce the burden on the mine detection machine, which took two years. But the battlefield waits for no one, at this time China's national war of resistance has broken out, and the Japanese soldiers helplessly found that the Chinese soldiers in front of them are becoming more and more fierce and fearless of death, and the war is becoming more and more cunning.

Especially in the early days of the Anti-Japanese War, after the Chinese soldiers received the true transmission of the German instructors, they learned from the German army's experience in disassembling a large number of wooden-handled grenade shells at the end of World War I, and using their pull-off fuses as improvised mines.

This kind of grenade body transformation of the emergency mine is easy to use, the Japanese army often stepped on the mines left after the occupation of the Chinese defenders, hehe, you little devil machine guns, artillery, tanks, planes sent us so many shells and bombs, we also have to pay back some small gifts, come and not be rude. Chinese soldiers also used cluster grenades to make anti-tank mines to bomb Japanese marching brigades and convoys.

The Japanese troops on the front line, who were blown up, hurriedly asked for help from the base camp, even if they carried a big burden like a Type 98 mine detection machine, it was better than being bombed blindly. On the one hand, China was too big, and the Japanese soldiers flaunted their might everywhere and ran into the vast sea of anti-Japanese people, and there were many teams in China to clean up the little devils.

On the other hand, Japan's electronic manufacturing technology and production capacity at that time were far less astonishing than after the 60s, when vacuum tubes were more expensive than the same weight of gold, and they were absolutely scarce.

What to do? The Japanese Army can only carry forward its own cottage tradition and require front-line soldiers to make and learn to use "mine detection sticks" extensively. The Mine Detection Stick sounds mysterious, but it is actually a long wooden handle with a metal probe attached to the front, and when used, the soldier bends down and inserts the mine detection rod into the ground at an angle of 45 degrees to find the mine through contact. This method of mine detection is relatively simple, and soldiers can learn it as soon as they learn it, but the efficiency is low and the accuracy is poor, even if a large number of soldiers line up in a dense formation to sweep the minefield, there is no guarantee that all mines will be found.

By the way, I have to lament the brainlessness of the devils, the German troops also have "mine detection sticks", but when people put a rifle with a bayonet and insert it in the ground at an angle of 45 degrees, it becomes the best mine detection stick. In order to deal with the Germans, the British laid a sea of mines in the fields of Europe, and the German soldiers used rifle bayonets to poke at the ground blindly.

However, as a simple mine detection equipment, the mine detection stick looks simple, but it is not easy to use. Ideally, as long as the insertion point is dense enough, the mine probe rod completely covers the swept area, but in actual combat, people will always miss, especially the ordinary devil soldiers who are not skilled enough to use them, but they are afraid of mines in their hearts, they may miss a few rounds with a shake of their hands, and these mines that miss the net can always give the Japanese army great damage.

Another point is that the Chinese Army, especially the anti-Japanese army under the leadership of Yan'an, has never been prepared to fight with the Japanese in an upright manner, so the number of ways to bury mines is not a regular army mine array.

Their mines are one in the east and one in the west, and if you poke in the ground for an hour or two, you may not be able to find a few, but if the devils dare to stride forward and go directly to the village and the base area, the mines will still find them. As a result, if the devil does not sweep mines, he will be blown up by mines, and he will slow down the mines, jump in circles one meter at a time, and when he enters the village, he will not see the food and villagers he wants. However, it is precisely because of the rustic Gongtu Eight Roads that the Japanese army has never dared to eliminate the mine detection stick.

Although it is not easy to use the electromagnetic induction mine detection rod to deal with the Yan'an army, it is very effective against the mines of the national army, because the mines of the national army are basically licensed goods made by regular arsenals, and the iron bumps of these standards are extremely powerful, but they are basically invisible in front of metal detectors.

Although there is not much munitions industry, most of the explosives in the base areas need to be captured, and at most they can make some black powder, and the explosion power is limited. However, by mobilizing the masses to use their brains, they used the altars and jars of the villagers' houses, the stones and trees on the side of the mountains to develop all kinds of land mines, and the scattered pottery shards, tiles, stones, and wooden thorns still made you bleed or even die on the hanging flowers of the dog's day.

Therefore, the Japanese army also admitted that there were many kinds of mines dug up in the Chinese battlefield, among which most of the mines were made in a hurry, only a few were made of metal, and most of them were pottery and stones with almost no metal parts and only filled with gunpowder. Without metal parts, it would be difficult for electromagnetic mine detectors to find landmines. Therefore, when encountering land mines, the Japanese army had to use primitive mine detection sticks to poke meter by meter.

It is a pity that although the national army has an arsenal, it has to give priority to grenades, artillery shells, and bullets in production, and even disdain to use the local methods of the Yan'an troops, the production of mines is very limited, and the number of troops assigned to the grassroots level is very small. Therefore, the number of mines equipped by the expeditionary force is very small, otherwise this large-scale retreat can completely arrange a mine array, and it will not cause such large casualties.

Although the number of mines is limited, when encountering scrap copper and rotten iron, the metal detector still makes a strange noise, and the Japanese army has to dig honestly, plus Chen Feng, they are not authentic, almost all the pots and pans and farm tools of the nearby people's homes, as long as they are all collected with iron, and buried them on the ground, more than 2,000 people worked all night, and the route was dozens of miles long.

When the Japanese army crossed the bridge overnight and thought that they could chase the expeditionary force with all their might, they found that it was simply impossible to move an inch, and the entire engineering wing was sent up, poked on the road for a whole night, and by the next morning it had not advanced to ten miles, and the commander of the 38th Division of the Japanese army, Shinichi Tanaka, was so angry that he almost vomited blood. Of course, this is a later story, so I won't show it for the time being.

After the Snow Wolf Special Combat Team attacked the Japanese Motorized Wing, they immediately ran all the way, and arrived at the place where they crossed the river in the evening. Not to mention swimming over, it is strange that a few small boats can't row to the other shore and are not overturned by the waves.

Fortunately, Su Canwen took out his walkie-talkie and asked, the three wounded soldiers and the remaining few people of the independent regiment had already crossed the river, and they were also staring at the river in a daze on the other side, Su Canwen immediately ordered them not to wait, and immediately rushed to Lewa to join the 75th Army.

Just when Su Canwen was at a loss, the knife came out again, saying that he had a way to cross the river, and told everyone that there is not only one bridge in the Liangmiao River, but also a chain bridge thirty miles to the east, although it is impossible to cross the car, but there is no problem with people.
