After all, the Red Guard Corps does not currently have a complete air system like the US military, and the focus of the troops' operations is also to rely on their own air defense means.

However, the 20,000-strong modular Marin Division is also the most powerful division-level establishment in the Red Guard Corps at present.

The combat capability is equivalent to an ordinary army of 100,000 people.

The Marin Division will also serve as the main force to regain Salah al-Din province, becoming the most powerful armed force in the offensive against Tikrit.

When the US-British coalition entered Baghdad that year, it only sent a brigade, which shows how much Cai Ruichen attached importance to the battle in this operation.

Because he needs to completely destroy the resistance of the Islamic State with absolutely powerful military force.

It is necessary to crush all ISIS forces in Salah al-Din province with the greatest force.

Four hundred main battle tanks, this is not the number of the complete establishment of the Marin division, a complete tank brigade must have at least four tank battalions, and one tank battalion is forty-two main battle tanks.

The two tank brigades and one infantry brigade are the main force of the Malin Division's operations at present, but the armored units directly under the division have not yet been built, otherwise the number of main battle tanks in the Malin Division will reach 560.

For this reason, a logistics unit of more than 2,000 men was responsible for the logistics work of the whole division, and with the addition of the Zhouqiao unit and other troops, the number of these auxiliary personnel alone reached more than 4,000 people.

If it were not for the modular battalion-level modular modules, it would have been almost impossible for such a huge combat organization to operate flexibly.

The Tikrite division, which is under construction, is not so large. There are only two brigades of combat strength in the establishment. The number is around 1,200.

The third divisional combat unit formed later. Like the Tikrit Division, it is a general combat unit.

As for the establishment of the heavy division, Cai Ruichen plans to have 300,000 troops, at most three, and the proportion will not be too much.

After all, the construction of the army also needs to be coordinated by some other fast-moving and flexible troops, and lightly armed divisions are still the key construction targets in the modern battlefield.

Integrated combat mission. Its role on the battlefield is increasing day by day.

This was the second time that the Marin Division had gone into battle, and it was facing the enemy, as well as all the enemies in the entire territory of Tikrit.

However, someone was faster than them, and when the Marin Division was less than fifty kilometers away from Tikrit, two squadrons of Intruder fighters had already entered the sky over Tikrit from a high altitude.

Inside the intruder fighter jet numbered 10002, Zhao Yunlong looked at the quiet city below, as the captain of the temporary formation this time. He has already announced his entry into the airspace of the warring territory.

As a long machine, his attack mission is not small. Of the two squadrons' fighters, only his fighter was carrying the eight-ton penetrating bomb.

The target of his attack was a twelve-story building in Tikrit, and the main target of the attack was not this building, but the underground of this building.

The twelfth floor itself has a strong defense, and if you want to attack the underground facilities of this level, you can only choose to attack vertically from the top of the building and penetrate the ceilings of all floors.

The main thing is to penetrate the reinforced concrete under the building, which is up to 20 meters thick, and then destroy a huge arsenal hidden underneath.

This arsenal is the largest arsenal of the Islamic State in Tikrit, and the weapons and ammunition in it can arm an army of 80,000 people, and it also has a lot of anti-tank missiles and individual anti-aircraft missiles.

As long as this building and the arsenal underneath are destroyed beforehand, all Islamic State forces in Natikrit will not have much weapons and equipment to use.

At present, all the information about this building has been collected a long time ago, including the structural strength of this building and the time of construction, and through the analysis of complete construction drawings, all the data of this building has also come out.

And this building is also a bone that is difficult to gnaw, because this was originally a station of the Iraqi National Guard during the Saddam period.

The buildings are all built with the strength of a three-level defense structure, and ordinary missiles simply cannot help such a building.

Even anti-materiel weapons may not be able to penetrate the main wall of this building, and the weakest point of the entire building is a 30-centimeter reinforced concrete structure defense.

Ordinary small-caliber assault rifles, at the most lethal distances, will not be able to penetrate such walls.

Therefore, ordinary missiles cannot deal with such buildings at all, unless they are those surface-to-surface missiles that strike with precision, or the air force carries heavy penetrating bombs.

At present, the entire building is also the headquarters of the Islamic State forces here in Tikrit, because it is the only place that is most suitable for the headquarters.

Zhao Long, who was on the plane, glanced at the building under the ground aiming system and couldn't help frowning.

Before the departure, the Air Force Staff had conducted a relevant analysis, and there was generally no problem in destroying the building with an eight-ton penetrating bomb.

But this information is not absolute, because it is not so easy to penetrate the ceiling of the thirteenth floor in one breath, which has already offset a large amount of energy, and then to penetrate the reinforced concrete twenty meters thick below.

"The other fighters, all waiting for my attack to be completed."

With a command on the radio, Zhao Yunlong immediately pulled up the fuselage and let the fighter quickly continue to climb towards the sky, directly climbing to an altitude of eight thousand meters.

Then his face became extremely resolute, and he directly pressed down the end, hung directly against the building, and stabbed vertically.

Vertically downward, still stepping on the accelerator of the engine, the speed of the fighter repeatedly increased, and the entire fuselage was shaking violently.

Zhao Yunlong in the cab did not lean forward because the fuselage was downward, but under the overload of more than 9G, the whole person was pressed to the seat.

The head is almost in the blank, and among fighter pilots, there are already very few people who can withstand overloads of more than 7G.

There are not a few people who carry 9G overload in the entire Red Police Corps, and Zhao Yunlong is one of them.

And the hero of the Air Force will defend the country, don't look at him as fat, but he is able to carry an overload of more than 11G.

But being able to bear it doesn't necessarily mean that there is really nothing at all, because this is already the limit.

Generally, the overload above 5G can make many people faint directly, and the pilots who have suffered the 7G overload are also in a relatively vague state.

Zhao Yunlong is no exception, the overload of 9G has made his eyes begin to be confused. (To be continued.) )
