Because of the emergence of many new weapons such as tanks and aircraft, trench warfare was relatively less used in European battlefields during World War II. In contrast, the Japanese in the Pacific War Zone faced overwhelming American artillery and air force, and used a series of deep-dig caves and bunkers to defend many of their islands.

That's right, under heavy firepower such as aircraft and tanks, islands became one of the few special areas suitable for trench warfare in World War II. Once the war enters a stalemate, positional warfare dominated by trenches will become the mainstream of confrontation between the two sides.

The process is actually very simple. The vanguard who successfully landed on the beach will establish a beachhead position under the cover of naval guns and bombers. It will cover the landing ships to dock and send subsequent large troops to Sicily. In order to resist the bombing of Allied battleships and bombers, and to prevent the Allied armored troops from advancing deep into the depths, the German and Italian coalition will also dig trenches as soon as possible.

After many confrontations, occupation and counter-occupation, a relatively stable position will appear. So, similar to the typical trench system in World War I, it consists of a series of two, three, four or more trench lines, parallel to each other and at least one mile depth. Each trench is dug into a zigzag shape so that the enemy standing at one end cannot fire along the edge of the trench. Each main trench is connected to each other through a series of traffic trench roughly perpendicular to them and connects to the rear. Food, ammunition, new forces, and mail are transported through these trenches. The intricate trench network includes command posts, front supply stations, first aid stations, kitchens and toilets. The most important thing is that there are machine gun positions to resist attacks, and there is a deep enough air raid shelter to cover the air defense of the troops, and then it comes into being.

There is another situation that is even more unfavorable to the Allied forces. Because they are too close to Italy, the Allied Combined Fleet cannot effectively block the Strait of Messina at all. This allows the German-Italy Allied Alliance armored forces and air combat forces to effectively support the island guarding forces in the "Sicily Trench System".

Regarding the tragic island-grabbing battle during World War II, you might as well refer to the last battle between the US and Japanese armies on the Pacific battlefield, which is also the largest amphibious landing battle - the Battle of Okinawa. The US military gathered 1,500 combat ships and auxiliary ships, including aircraft carriers and battleships, with 240,000 landing divisions and 450,000 total land, naval and air force, and was determined to open the last barrier that Japan relied on to cover the land. In order to block the US military from the land, the Japanese army did not hesitate to use the Yamato battleship as a suicide weapon, 2,000 fighters acted as suicide aircraft, and gathered 120,000 elite troops to die with the US military.

Fight to the end. The bloody battle lasted 82 days, leaving the Japanese army with more than 100,000 bodies on Okinawa, only 7,000 surrendered, 7,830 aircraft and 20 ships. The US military suffered 75,000 casualties, 763 aircraft, 404 ships, 372 tanks, thousands of others committed suicide after the war, 20,000 people were mentally ill, and 14,000 retired from active service. Army Lieutenant General Buckner became the highest-level US general in the Pacific battlefield. 100,000 indigenous people on Okinawa were also killed in this island-seizing battle, and the lucky people had to face their fragmented homes.

So a few weeks after the end of the Battle of Okinawa, the US military used atomic bombs to bomb Hiroshima and Nagasaki, accelerating Japan's unconditional surrender.

You should know that if the military industrial system and war equipment are compared, the Japanese army on the Pacific battlefield is far less than the German and Italian coalition forces on the continent.

In addition, Sicily, which is completely different from the strategic location of the Okinawa Islands, is only "a line" away from the Italian mainland. What's even more terrifying is that in 1943, under the "World War II plot fragments similar to the plot fragments of World War II, the Allied forces not only failed to complete the "Manhattan Plan", but were also taken the lead by the "Revenge Weapons Plan" of the Third Reich.

Although Sicily's fall is almost a foregone conclusion for the senior management of the Third Reich. The British and American allies, which were consumed in large quantities, were almost a foregone conclusion. During the strategic opportunity period, the British and American allies were no longer able to launch a larger European landing war.

The spillover effect has occurred in the surging continental battlefield.

In the Battle of Stalingrad, which ended on February 2, 1943, a total of one million people died in the battle. The German Sixth Army had 260,000 people and 91,000 people were surrounded, and only 5,000 people returned to Germany alive after the war. During the most intense stage of the battle, both sides invested more than 2 million troops, 2,000 tanks, more than 2,300 aircraft, and 25,000 cannons and mortars. In the two months of September and October 1942, the Soviet army had only five infantry divisions.

Crossing the river to reinforce, but the German army invested no less than twenty-seven infantry divisions and nineteen armored brigades reinforcements. Its first-line division often suffered 70% casualties, and only 30 and 40 people remained in a company. The German army successively invested in Stalingrad, and increased from the original twenty-five divisions to fifty-one divisions. From July to November 1942, the German army lost a total of 700,000 officers and soldiers, more than 1,000 tanks, more than 2,000 cannons and more than 1,400 aircraft.

Another point must be mentioned.

During the battle, the Soviet Railway transported 300,000 vehicles of military equipment to the Stalingrad area. During the entire battle, a total of 9,568 vehicles were consumed, and 8,353 vehicles were consumed, exceeding 13% of the amount of shells consumed for the battle of Berlin. All factories and enterprises in Stalingrad established annihilation battalions, and more than 80,000 people were added to the Red Army troops. Most of the people who stayed in the factory continued to persist.

Production. For example, only 10% to 15% of the workers were left at most in each factory in Kirov area, but it produced 5,000 tons of food, 100 tons of mustard oil, 67 tons of soap, 12,000 bottles of mixed fuel, 5,000 military stoves, 1,300 landmines, and the Stalingrad factories were supplied on July 8, 1942 alone, more than 4,800 front-line tanks, cannons and mortars.

It is said that the Soviet Union, which was preparing for a large counterattack, is also stepping up the development of rail-changing trains so that military trains can smoothly transition from the wide-gauge 1528 mm railway left by the Tsarist era to the 1435 mm standard rail used in Germany and the German-occupied areas. In order to continuously convey strategic materials, the Soviet senior management has issued plans to expand the Siberian Railway. The first of all, many monorail sections are expanded into dual-rails.

“Free Gauge

Train, referred to as ‘FGT’)” is a train with a variable gauge, with the purpose of designing vehicles designed to solve the direct operation between routes with different gauges. Japan has developed a high-speed railway train with a variable gauge since 1994. The purpose is to allow the train to travel on the 1067mm narrow gauge track commonly used in Japan and Shinkansen tracks built with 1435mm standard rail. Its purpose is to allow the same train to travel on the Shinkansen and the incoming route ("incoming route" is a Japanese railway term derived from the Japanese word "incoming", which means "always, always, existing". It refers to other railway lines except Shinkansen (i.e., high-speed railway), including the old Japanese state-owned railway (JR) and other private railway companies, which can increase the route changes of trains and reduce the number of passengers' transfers.

In fact, if the Nazi Third Reich did not fall, similar to orbital cruise technology, FGT orbital transformation technology would have been implemented earlier.
