A soldier usually spends a short time in the front-line trenches, where he stays for a day to two weeks before returning to the rear. Australia's 31st Battalion once spent 53 days in the Willer 61 Bridonne trenches, but this is a very rare example. A British soldier usually spends a year in the trenches of the front line, and 10% of the time in bunkers or trench bunkers on the support line, which is considered a front-line experience, which means that the soldier does not spend more than a quarter of the time in the line of fire. The rest of the time, 30% is spent on standby in tent barracks on the reserve line, or changing guards or filling vacancies, while the other 45% is spent recuperating in hospitals, traveling, vacationing, training, etc. It looks pretty good, you must know that even the Chinese army during the Anti-Japanese War was not a bloody battle on the front line every year, and after a month's battle, there was generally a time of rest and reorganization for three or four months, and the Japanese army was generally the same. No country's army can fight around the clock, and even if the material supply is not a problem, the soldier's spirit will not be able to withstand the accumulated tension and pressure, become numb or crazy, and lose the battlefield acumen and normal judgment that a veteran should have.

Even when serving on the front lines, a soldier usually only participates in a few battles in a year, such as offensive, defensive, or assault, etc. The elite divisions of the Allied Army included the British regular divisions, the Canadian Corps, the French XX Regiment and the Anzac Corps.

There were places where there was little military action during the war, which made life in the trenches easy. When the 1st Anzac Regiment arrived in France in April 1916 after the retreat from Gallipoli, they were sent to a fairly peaceful place, but there were always heavy battles in other places. On the Western Front, Ypres was a hell every day, especially for the British troops located in the exposed trench salient. In places where there was little military action, snipers, artillery fire, disease and poison gas still took a heavy toll on them. In the first six months of 1916, the British army had not participated in major battles before the Battle of the Somme, but the number of casualties was still 107776.

A section of the front line would be assigned to an army corps, which usually consisted of three divisions. Of the three divisions, two would be stationed in adjacent positions, and the third would rest in the rear. This assignment of tasks would be carried out to each army unit, so that of the three brigades (called regiments in the Germans) in each division, two would be stationed at the front and the third in the rear as a reserve. Of the four battalions in each brigade, two battalions are stationed, two battalions are rested, and the tasks of the company and platoon are so on. The lower the level, the more frequently the unit is transferred.

During the day, the troop sports are met head-on by snipers and observers located in hot air balloons, so the trenches are often quiet at this time. The night is the busiest time for the personnel in the trenches, the movement of troops and supplies, the maintenance of barbed wire and trenches, and the reconnaissance of enemy lines can all be done under the cover of night. Listening posts in no-man's land will detect enemy movements.

The purpose of the attack was to capture prisoners and capture intelligence on enemy troops. As the war progressed, raids became part of the British strategy, which would keep the troops motivated and prevent no man's land from falling into German hands. The cost of this tactic was high, and a post-war British study concluded that it did not gain as much as it lost.

At this time, the trench fighting was very fierce, and about 10% of the soldiers were killed. In the Second Boer War and the Second World War, only 5% and 4.5% of the soldiers were killed, respectively. On the Western Front, 12 per cent of the British and Commonwealth Dominion forces were killed, and the total casualties (wounded and killed) reached 56 per cent. Considering that every soldier fighting on the front line has 3 soldiers who provide him with logistics (ammunition, supplies, medical care, etc.), it is almost impossible for every soldier who actually participated in the battle to survive without being wounded. In fact, it is true that many soldiers were wounded more than once.

At that time, medical treatment was still very primitive, and life-saving antibiotics had not yet been discovered. Fairly minor injuries can also be fatal due to infection and gangrene. 12 per cent of German soldiers were killed by leg wounds and 23 per cent of men with arm wounds, with the main cause of death being infection. Forty-four percent of U.S. casualties were due to gangrene. Of these, half were wounded in the head, and of the soldiers wounded in the abdomen, only 1% survived.

However, the situation was greatly improved in the spring of 1917, when the first large-scale medical team of the Chinese Expeditionary Force arrived in France, and 3,200 military doctors and nurses from China arrived, all of whom had undergone rigorous academic education in the new medical schools in various places, and also practiced in hospitals in large cities for 3-6 months, plus a month of special training in battlefield ambulance, it can be said that these angels in white from the Far East brought a truly modern field medical system to the Allied army. Of course, all kinds of antibiotics and other drugs provided by Chinese standard medicine, as well as disinfection equipment and medical examination equipment are life-saving weapons, and the mortality rate of soldiers has been greatly reduced, which has greatly improved the morale of the front-line troops, and it is even said among the soldiers that if you have a red gourd banner behind you, then as long as you are not shot in the head by a sniper, you have hope of survival.

In fact, three-quarters of the wounded in World War I were wounded by artillery fire. Injuries from shrapnel from artillery shells are usually more severe than those caused by bullets. Shrapnel from artillery shells will carry some dust into the wound, which will most likely lead to infection. These factors mean that the mortality rate of a soldier with shrapnel in the chest is three times higher than that of a soldier with a bullet in the chest. The explosion of a shell can also be fatal by causing a concussion. In addition to the physical damage, the shelling can also cause psychological damage. Prolonged shelling often led to soldiers going into shock, which was not fully understood at the time.

As in other wars, the biggest killer of soldiers in World War I was disease. Sanitation in the trenches was poor, and common infections included dysentery, typhus and cholera. Many soldiers have suffered from parasitic infestations and corresponding infections. Poor sanitation also infested the trenches with fungus, leaving soldiers with trench mouths and trench feet. Another major killer was the exposure of soldiers, who often had sub-zero temperatures in the trenches in winter and who did not have enough clothes to wear.

With the inflow of all kinds of Chinese materials, the treatment of the troops on the Western Front has been greatly improved, and the lives of the soldiers are not so desperate, but the Minister of Finance of the French government has a face like earth every day, and from time to time he opens the window facing the street to look, I wonder if he is looking at whether there are any Chinese transport airships bringing new supplies from Cherbourg or looking at the height from the ground, planning to jump into the plane and never have to worry about the already terrible financial situation of France again.

With Petain's carefully prepared spring offensive once again becoming a senseless sacrifice, the last of the Allied morale was squandered, and perhaps they would have been able to launch a strong offensive now, if the Germans were not also exhausted. However, by this time the war had become meaningless, perhaps for Germany, a doomed defeated country, but for Britain and France, the former world hegemon and army first, they had lost too much, and whether the war ended with their victory or not, they were the biggest losers. The United States had begun to show more and more obvious intentions to join the Entente, but unlike the previous situation, Britain and France were somewhat hesitant about the question of the United States entering the war.

In this white-skinned world, China's rise is just a redistribution of interests in the Far East, and it will not pose much of a threat to the core interests of Britain and France, while the United States, the world's largest industrial scale and huge local territory and population base, are the first heirs to the world hegemon, and Britain, which is already the imperial sunset, does not want to let its cousin have a brother and a brother to give up the throne, not to mention that China's fourth expeditionary force has been assembled in Qingdao, Shandong, Waiting for 200,000 Chinese soldiers to set foot on French soil, will the Germans still hold on? Moreover, although Britain and France are shy in their pockets, China's commercial development of Southeast Asia has kept the capital chain of Britain and France from being too tight, and of course some rights that have to be ceded are also due prices. And under the stimulus of China's troops, Japan finally planned to send 2 divisions of Japanese troops to Europe to participate in the war, but it was rejected by France, the arrogant rooster was conquered by the Chinese air force and armored clusters, but those who carried the thirty-year-old small guns are not as elite as the Chinese expeditionary force, if you fill the trenches, it is enough to have Indian Asan and Baotou buddies in North Africa, these dwarfs have backward weapons and dull tactics, but Japan's troop conditions are still lions' mouths, Trying to ask for the British and French concessions in China and a large area of land in Southeast Asia, if it were not for the fact that the Russians could no longer hold on and urgently needed reinforcements, the French foreign minister even had the urge to throw this guy called Xiyuan Temple out of the Elysee Palace. Do you think you are the Chinese Defense Forces? Such crooked melons and cracked dates are only worthy of Lao Maozi as cannon fodder, so don't go to France to waste everyone's food.

The indifference of Britain and France made the Japanese government panic, and the conditions for sending troops had to be lowered again and again, and finally at the cost of part of the mineral development rights in Southeast Asia and the concession rights in the South Sakhalin area, these dwarfs were invited to cross Siberia to the Eastern Front to fight side by side with their former sworn enemy Lao Maozi.
