Transmigrated as the Crown Prince

The mine detectors used by engineers and soldiers are actually just a kind of "metal detector". The mine detector oscillates the coil in the electronic circuit and the probe ring to form a fixed-frequency alternating magnetic field. When metal approaches, the principle of metal magnetic conductivity is used to change the inductive reactance of the coil, thus changing the oscillation frequency and sending out an alarm signal. Yes, it does not work on non-metals. During World War II, mine detectors in various countries all used relatively simple electronic tube circuits, which had poor ability to identify landmines. Naturally, they could not detect German tempered porcelain landmines that did not have much metal content.

The Soviet battalion commander didn't know this and thought it was the engineers' negligence that caused him to lose a few more soldiers, so he couldn't help but cursed. "If you miss one more person, I will shoot you all!!"

The engineers and soldiers were also very innocent, so they could only search more carefully.

But just after walking more than ten meters, click! With a soft sound, a ball bounced from the ground into the air. Before the surrounding Soviet troops had time to react, those terrifying balls bounced up from behind, left, and behind them!

boom! boom! boom!

Accompanied by dense explosions, dense steel balls swept around, and a large piece of the surrounding Soviet troops fell down. Even the battalion commander was hit by the steel balls and his arm was injured. After the explosion, looking at his soldiers who fell to the ground and howling in pain, the battalion commander's face was almost deformed with anger. He pushed away the medical soldier who was about to bandage his wounds and yelled at his messenger. "Sheva! Go to the leader and ask for support!"

On the side of the railway, the nearby Soviet troops rushed here and launched emergency rescue. They carried American soldiers out of the carriage one by one. Some have become corpses, and some have been seriously injured. Screams, groans, and painful cries came and went one after another, which was very harsh.

In the nearby temporary command post, division commander Savvaj's brows were knitted tightly together, and his eyes revealed unconcealable fear and nervousness. Comrade Stalin sent them to guard this railway, but now that something like this has happened, they will be held responsible if the superiors hold them accountable. "How many casualties were there?"

"More than 800 people have been carried out, of which more than 300 have been confirmed dead, more than 200 are seriously injured, and the rest have varying degrees of minor injuries."

This train transports 1,500 people. According to this ratio, more than 300 corpses would have to be carried out? Just as Commander Savvaj was about to say something, urgent shouts rang out from outside. "Comrade Commander of the Vladimir Company, Comrade Commander of the Vladimir Company!"

"Come in!"

The messenger, Sheva, hurried in, saluted everyone and then looked at the commander of the Vladimir company aside. "Comrade Commander Vladi, we encountered a German minefield. Comrade Commander Andreevich was also injured and is in urgent need of support."

"What?" Captain Vladimir frowned slightly. "Haven't engineers been dispatched to clear mines?"

Sheva shook his head. "Comrade commander, the engineers failed to detect the German mines."

"Damn it!" Captain Vladimir Putin cursed softly, and sent the remaining two battalions under his command over to pick up the wounded.

Fred, who had already returned to the camp, faintly heard the explosion in the distance and smiled. "It seems these idiots have been tricked. Let's go there again after the railway is restored tomorrow."

In times of war, it was easy to destroy railroads. You can use explosives to blow it up, or you can use the simplest tools such as crowbars and iron rods to destroy it. But it is easy to destroy, and it is also easy to repair. Even if a relatively long section of railway line is damaged, the repair party only needs to drive over with a construction truck and re-pave the rails to continue transporting people and materials.

Therefore, during World War II, whether it was an Asian battlefield or a European battlefield, destroying railway tracks was not the best option. The best option was to blow up culverts and locomotives. Even if a railway bridge is bombed, an engineer battalion can repair the bombed railway bridge overnight with no piers left, but once the culverts and tunnels are collapsed, it will be difficult to restore them.

The locomotive requires the integration and assembly of parts produced by different factories, which is difficult to manufacture within a day or two. It is difficult for any country to produce a brand new locomotive in a short period of time. In order to cope with possible risks, many countries will have locomotives in stock for emergency use. Once the supply of these stock locomotives exceeds demand, it will be equivalent to destroying the enemy's transportation capability.

"These idiots!! Didn't they send troops to protect that railway? Why was it attacked?!" News of the attack on the train transporting our own soldiers reached the United States, and President Willkie became furious. "What's going on?!" He heard that the Soviets sent three divisions to guard the railway. He thought Stalin was good at getting things done, but now he has such virtue? !

"The Trans-Siberian Railway east of Krasnoyarsk was attacked by the German army, causing a train transporting a regiment of our army to derail and overturn, and was subsequently strafed by the German army."

"How many casualties did our soldiers have?"

"The specific number of casualties has not been transmitted yet, but it is estimated that it will be no less."

"Oh God!" President Wilkie couldn't help but slapped his forehead. These poor soldiers died in a foreign land before they even fought against the Germans! "How many German troops? Do the Soviets have any countermeasures?"

"According to the Soviets, there is at least one company of firepower. They have sent people into the mountains to destroy the German troops."

Then Chief of Naval Operations Adm. William Daniel Leahy hurried in. Because of the ridiculous "Ice Carrier" incident, the former Chief of Naval Operations Harold Stark was forced to resign and was replaced by General Leahy, who had already retired. After all, General Leahy's ability is obvious to all. He became the first officer in American history to receive the rank of five-star general in the original time and space. Therefore, when a suitable candidate could not be found for a while, the old general could only be asked to come out.

General Leahy walked into the office excitedly and said loudly. "Mr. President, our scientific research department has developed active sonar!"

"Active sonar? What is that?" President Wilkie was confused. After all, he was a politician, not a military strategist.

General Leahy explained the principles of active sonar to him, and President Wilkie's eyes suddenly lit up after hearing this. "That means we can catch that German submarine, right?" That damn German "ghost" submarine is still wreaking havoc on the eastern sea lanes of the United States, and it has sunk countless ships.

General Leahy nodded heavily. "Yes, Mr. President, from now on underwater submarines will be invisible to active sonar! German submarines will no longer be a threat!"

"Great!" President Wilkie slammed the table with great excitement. "Then when can we go into actual combat?"

"We have a destroyer that is about to be commissioned. The installation work of active sonar has already begun. The destroyer can be put into battle in a week at most!"
