Time is too precious to be wasted.

Zhang Tan is not idle, he can do a lot of things in seven days, he is studying how to break through the tactics of the empire's defenses.

The Imperial forces and civilians are shrinking, and they are gathering on the principle of being able to concentrate and not disperse.

There is such a result, which is exactly what Zhang Tan wants to see. The denser the gathering, the more beneficial it is for one's final action.

There are advantages and disadvantages, and although it is good to gather together, it will take a lot of twists and turns to effectively crack down.

If conventional means are used to attack the five plots of land that have been divided, it is basically an old-fashioned urban warfare. The main target of the elimination is the resistance group that remains in the city, and if the resistance is eliminated, the two sides will inevitably be short-handed.

It is both time-consuming and labor-intensive, and Zhang Tan has tried several novel ways of playing in several civil conflicts, and the results have been different.

Especially to avoid casualties, Zhang Tan once used a large number of robots to replace human attacks, and the final results were very unsatisfactory.

After many experiments, a little valuable attack method, such as a devastating destruction method, can reduce the battle between the two sides for every inch of land.

But his tactics need to be improved. Now it is not perfect, due to the environment and conditions in which Zhang Tan was located at that time, it is difficult to achieve the destructive power required by Zhang Carbon.

Therefore, his theoretical attack is more theoretical, and it does not meet Zhang Tan's requirements, and he needs to find other methods.

If the required destructive power is reached, unless a nuclear bomb is used. With the enormous destructive power of a nuclear bomb, it is enough to destroy all ground and underground targets.

In terms of the area of the empire, throwing one every tens of kilometers and destroying the fortifications in the city with the most intensive and violent bombing can meet Zhang Tan's theoretical requirements.

The problem is that a nuclear bomb can kill the enemy, but it can also harm itself. The collateral consequences of dropping hundreds of nuclear bombs in a really dense manner have been tested in many regions such as the United States.

Moreover, the use of nuclear bombs will be subject to great procedural constraints. Zhang Tan has no right to use nuclear bombs, let alone directly transfer nuclear bombs from the nuclear arsenal to carry out a nuclear strike on the empire.

If you want to use a nuclear bomb, you need to approve it in layers of terms. A final nuclear attack is not possible unless humanity encounters an imminent attack of extermination.

Even if he could gain the right to use nuclear weapons, the war might be over.

Nukes cannot be used, and other methods of attack can be used instead.

The Grand Alliance is not like the country he lives in, not only is it poor, but it is difficult to reach the sky with some high-tech weapons.

What weapons are not weapons, if you have a pair of hardworking hands you can create your own. Otherwise, you won't be able to wait for any of the weapons you need.

As the commander of the Grand Alliance, he is not constrained by technology. Zhang Tan put forward the requirements for attack weapons to all the participating countries, although the requirements were too harsh, there were always a few countries that could meet his demanding requirements on weapons.

Weapons need to be prepared and cannot be delivered to the battlefield in time for the time being.

It is a coincidence that all the transportation and dispensing takes several days to operate, and the time for transporting weapons coincides with the seven-day rest, which is a very coincidence that time is not wasted.

Time cannot be wasted, and a military inspection is required before the general offensive begins. Don't look at the fact that all sides have a lot of experience in snatching, it may not be reflected in joint operations.

Before the start of the war, the coalition forces have to conduct a coordinated deduction of all the participating countries, and constantly deduce several times, how to know the previous combat level of each country. What's more, this is a coalition attack, and mutual cooperation needs to be unified before the war, and the military inspection just allows the coalition forces to increase mutual understanding.

However, it is not realistic for millions of people to conduct exercises, and it is better to directly push them onto the real battlefield and actually attack a few weaker tactical targets.

Zhang Tan's plan of action is codenamed Plant Pruning, and their job is to capture or divide the scattered forces within the Empire.

The operation was very effective, and after trimming, most of the civilians and idle forces were annihilated or captured. The rest of the main forces avoid excessive casualties concentrated in the main area.

In order to test his tactics, Zhang Tan mobilized several bomber groups to attack the besieged area that was about to be attacked. The bombs carried by the bombs were not ordinary bombs, they carried super heavy bombs, as well as heavy electromagnetic bombs, and a variety of bombs were temporarily formed at the rear airfield for bombers mixed with humans and robots.

In order to ensure the safety of the bombers, Zhang Tan mobilized the main air forces of the five countries to carry out an air blockade of the empire.

Despite the Imperial Air Force, it was still unable to break through the no-fly zone established by the Grand Alliance.

The Grand Alliance blocked the entire no-fly zone with a completely overwhelming posture, and the air force dispatched by the Empire was no more than a symbolic dozens of sorties, and in the face of the blockade of hundreds of planes by the Grand Alliance, they fought nothing more than a few unseemly air battles.

The no-fly zone was blocked, and Zhang Tan sent his bomber brigade. The bomber group consisted of sixteen flying squadrons from the three countries.

Sixteen bomber squadrons are already all squadrons in the world capable of delivering super-heavy bombs.

Although the number of bombers is large, the number of bombers at disposal is too small. It was okay to annihilate the enemy in a small area, and if a large-scale bombardment of the Empire was really launched, sixteen squadrons would be far from enough.

It's already good to use, so let's send it out first to see how it works.

In order to test his theory, Zhang Tan turned a small concentration area called Ercheng on the left side of the empire into a testing ground for his tactics.

The ear city is shaped like an ear, with one floor of buildings surrounding one storey building, fifteen kilometers long from east to west, and about six kilometers wide from north to south.

As soon as the Empire's scattered forces were defeated and retreated into Ear City, the troops surrounded by the Grand Alliance immediately blocked Ear City. Two squadrons of bombers were sent from the air to carry out a rough bombardment of Er City.

In the first round of attacks, Zhang Tan dispatched all sixteen bomber squadrons at one time, and Zhang Tan first used a powerful number of attacks to deter the defender's spiritual fortress.

At present, only three countries in the world insist on manufacturing and producing super-heavy bombs, and other countries have already switched to producing more flexible and compact attack bombs.

In addition to the three countries, other countries have provided a large number of cluster bombs and white phosphorus incendiary bombs, which can be bombed with a mixture of multiple ammunition to make up for the shortcomings of their own ammunition.

The heavy bombs produced by the three countries are available in three sizes: 14.6 tons, 9.5 tons, and 7.7 tons.

The three types of bombs are the oldest air-dropped bombs, and there is no reference to precision guidance, so in order to increase the accuracy of delivery, precision guidance has been temporarily added to the three bombs.

Once everything is ready, you can follow the steps in the drill to carry out the attack.

Zhang Tan gave the order to attack.
