In the early morning of the next day, the calm of the floating island fortress was shattered by the loud wake-up call.

Groups of heavily armed soldiers assembled on the school grounds, the morning sun had not yet fully risen, and the voice of the roll call came one after another, kicking off a new day.

I thought it was another ordinary day, but the weight-bearing run in the morning had not yet begun, and battle sirens sounded all over the Floating Island Fortress.

The troops immediately assembled in a regimental-level combat sequence, suspended all training tasks, and all military commanders went to the division-level headquarters to report as soon as possible.

It was only at this time that the Red Guard Corps knew that it was going to conduct its first annual live-fire exercise.

All the soldiers on the Floating Island Fortress began to march through the chrono portal in the barracks in a company and assemble at the exercise ground on the tenth floor of the base.

The ten underground floors of the base are dedicated to the world of exercises, in this world, there are all kinds of complex actual combat terrain around the world, complete trenches and ravines and urban buildings.

Groups of soldiers assembled here, and the 1st Army Division of the Red Guard Corps, which received the order to participate in the exercise, prepared the subjects for the exercise.

The exercise site is arranged in a hilly and undulating mountain and forest area, and there is only one exercise task issued by the War Department, that is, infantry and artillery coordination.

It takes less than two hours for the First Division of the Red Guard Corps to prepare, and two hours after the siren sounds, Fan Yize will arrive at the exercise ground to watch the exercise.

Without preparation, it will be quite difficult to accomplish the objectives of this exercise.

Under the quiet attention of tens of thousands of soldiers of the Red Guard Corps, the artillery units of the 1st Division completed the construction of artillery positions within an hour, marked the elements, and prepared artillery and shells.

Ten kilometers away from the coordinates of the exercise, forty-eight 105-mm howitzers of the artillery brigade of the 1st Division were ready, four hot air balloons from the reconnaissance battalion of the artillery brigade were lifted into the air, and eight reconnaissance platoons on the ground were heading to the coordinates of the exercise.

The exercise has actually begun, and the exercise of the nature of actual combat testing is not a script that the director has done, and Fan Yize does not want to see the picture of a drill directed by the script.

Without any prior notice, when the men of the 1st Division's Artillery Brigade thought that the exercise had not yet begun, three of the eight reconnaissance platoons that had gone to the target for ground reconnaissance lost contact with them after they arrived at the target area.

Five other artillery reconnaissance platoons also sent warnings of enemy attacks by radio stations and began to provide shelling coordinates.

At the same time, Fan Yize sat in the console of the base, paying attention to this exercise.

In the army battlefield before the advent of tanks, only artillery dominated the ground war, a veritable king of war.

Throughout the first world, human warfare for the first time showed obvious characteristics of competition and attrition in terms of comprehensive national strength.

This war was based on industrialization, carried out large-scale mobilization of manpower and material resources and long-distance transportation, and had powerful artillery firepower for sustainable bombardment, and new sea, land, and air weapons such as airships, tanks, and submarines were put into use on the battlefield one after another, and even poison gas came in handy.

However, in terms of the decisive outcome of the war, World War I was essentially a land offensive and defensive war on the European continent.

Before World War I, it was becoming increasingly difficult for the attackers to win the battle by relying solely on the numerical superiority of infantry in the face of a solid defensive position consisting of machine guns, trench systems, and barbed wire.

Even after a prolonged, high-intensity artillery bombardment, coupled with the continuous assault of the group's infantry, it was often possible to achieve only a limited breakthrough in the enemy's defensive line.

Machine guns made an impression in World War I, but artillery was the weapon that really dominated the battlefield. Figuratively speaking, the First World War was a war of artillery, but before the First World War, the status of artillery in the war far exceeded that of the First World War.

On the side of the exercise screen in Fan Yize's eyes was a list of several pages of artillery construction.

From the mortars in the trenches to the super train guns of seven or eight hundred millimeter caliber, even Fan Yize, who is not a pure artilleryist, saw this dazzling array of artillery, and he was full of pride for a while.

Artillery, which dominates the era of war at this moment.

For the first time in human history, artillery killed more people than small arms and air strikes, and more than any other weapon in World War I, and probably for the last. In the later stages of the war, the superiority of artillery was fully exploited, and the machine guns lost their effectiveness. Without artillery, the infantry could neither win in the offensive nor remain undefeated in the defense.

The artillery conquest and infantry occupation became the mode of operation of the First World War, which put forward high requirements for a country's artillery supply capacity, which in turn depended on a country's industrial strength.

As for the fact that there are veterans in the old army who are afraid of machine guns and recruits who are afraid of artillery, in Fan Yize's view, this is just a completely different understanding in the war environment.

The main reason is that at that time, the number of artillery equipped in the warlord troops in my hometown was not large, and it was mainly mountain artillery and infantry artillery, and there were very few shells. Therefore, the recruits are often intimidated by the rumbling of artillery, but the veterans know that the real horror is the machine gun on the opposite side.

The Red Guard Corps completely took the artillery doctrine to the extreme, and throughout the First World War, no country's division-level troops were equipped with 48 large-caliber howitzers in one go, let alone before the First World War.

Before World War I, only corps-sized units were equipped with a certain number of artillery, and during this period, all kinds of artillery were gradually installed in the troops, and only the Red Guard Corps had a unique advantage.

Moreover, in the war era when wired telephones and wired telegraphs were commonly used as command links in all countries, the Red Guard Corps had fully equipped radio communications and reached the battalion and company level, which was again a huge advantage of the times.

At present, the radios of various countries are still only equipped on warships, and due to the backwardness of technology, the wireless communication distance is only between a few hundred meters and thousands of meters, and the practicability is very small.

Under the picture of augmented reality projection, Fan Yize sat in the high altitude of the exercise world, watching the dense artillery fire raging below, and the devastation of 48 105mm howitzers erupted, and the entire mountainous area that was targeted was completely covered by dense artillery fire.

In the process of shelling, a large number of targets were quickly destroyed, and the hot air balloons and artillery reconnaissance units approaching for reconnaissance also guided the shelling coordinates again and again.

In the process of shelling, two infantry companies of the 1st Division reached the foot of the target hill and, amid the rumbling artillery fire, advanced to the edge of the shelling coordinates, and as the artillery fire extended, the two infantry companies followed the pace of the artillery advance, withstanding the heat wave of the artillery, and advanced to the top of the mountain.
