Czechoslovakia, which had been invaded by Germany and Poland, was by no means completely defenseless, but the day after the German and Polish invasion of Czechoslovakia, the Zess army broke through Bratislava, the capital of Slovakia, which had been briefly occupied by the rebels.

The Wehrmacht and Polish forces also carried out air strikes against Czechoslovakia, but just as American air strikes against Chinese troops were almost unsuccessful, German-Polish air strikes were ineffective against the stubborn Zess air force. Of course, the Luftwaffe will inevitably outperform the Zess Air Force, but a considerable part of Germany's air force has been withdrawn to support the US military in the operation, so the air attack on the Zess Air Force actually did not exceed 100 aircraft sorties.

In fact, the Luftwaffe's fighter stock has always been relatively limited, with only more than 100 Tornado, and the Typhoon fighter, a product of the European Joint Fighter Program, has just been launched, and the Luftwaffe has not yet sent it into active service. In order to make up for the shortage of Luftwaffe fighters, the US military directly allocated a batch of F-16 fighters to the Luftwaffe that were on the verge of retirement to improve the combat capability of the Luftwaffe.

In addition to Germany selling the MiG-29 of the former East Germany to Poland at a symbolic price, Poland also received a lot of MiG-29 sold by the former Soviet Union countries.

Although the Czechoslovak Air Force, which defended its homeland, did not have as many fighters as Germany and Poland combined, its fighters were quite high. The Jets Air Force first imported a batch of FC-1 Thunder fighters from China after selling the MiG-29 and other old Soviet-made fighters, and in the late 90s, the Jets Air Force imported a batch of second-hand FC-9 Shadow Leopard fighters from China at low prices. Overall, the Zess Air Force maintains an air force fleet of more than 80 fighters, which is relatively strong in terms of the size and population of Czechoslovakia.

Of course, the main force that really helped Czechoslovakia to fight the gap from Germany and Poland was the four Hongqi-9 air defense systems imported from China in 1997. The Luftwaffe wanted to attack these dangerous weapons in the first wave, but they were first countered by these anti-aircraft missiles. The anti-aircraft missiles combined with the interceptor fighters of the Zess Air Force made the German-Polish Air Force basically not play much of a role in supporting its ground forces in invading Czechoslovakia.

Soon after, when the Czechoslovak government condemned NATO's actions and officially announced its accession to the SCO, the aviation units under the Chinese European Command came to Czechoslovakia's aid. In order to maintain the strategic balance of power in Europe, the Chinese PLA, which lacks ground forces, deliberately strengthened the air force of the troops stationed in Europe. Therefore, the Chinese Air Force stationed in Yugoslavia, Romania and other places is equipped with a large number of fifth-generation main fighters such as J-11 and J-20.

The German-Polish air force had not yet taken the slightest advantage in the skies over Czechoslovakia, when it encountered the Chinese air force to stir up the situation and suffered heavy losses, but the US military would not sit idly by and watch Germany and Poland suffer heavy losses, and the US European forces gathered the two major powers of Britain and France, plus second-class powers such as Denmark and the Netherlands, to form a joint air force in an attempt to suppress the air force of the SCO coalition.

Relatively speaking, air battles in Europe were not as fierce as those fought in the Southwest Pacific and Indian Ocean theaters, large groups of air dogfights did not take place, and there were still more 2-6 fighters engaged in skirmishes with enemy aircraft, but when scaled into the entire battlefield, it was not small.

On the ground battlefield, the Germans, who had done well, were also challenged by the Thiesian Army. Czechoslovakia purchased a large number of advanced Chinese weapons and built five heavy mechanized brigades, which formed the main combat force of the Zess Army.

After the chaos of the initial German-Polish invasion, the Thiess Army was quickly mobilized to strike at the Germans and the Polish armies. After seizing successive Czechoslovak towns, the German 26th Airborne Brigade abandoned the heavy armored units and infantry brigades that were covering itself, and launched an offensive against Kosice, an important town in western Slovakia.

However, the airborne brigade was ambushed by the 5th Heavy Mechanized Infantry Brigade of Thes on the outskirts of Kosice. The German 26th Airborne Brigade lacked heavy weapons, only some light towed artillery, a small number of wheeled infantry fighting vehicles, and in the face of the well-trained VT-4 tanks of the 5th Heavy Mechanized Infantry Brigade of the Thiess and the attacking mechanized infantry, the 26th Airborne Brigade put up very stubborn resistance, but suffered heavy losses and had to retreat to rest.

The situation of the Polish army is even worse, when a Polish army division marched into the Czech Republic, it encountered a joint attack by the 2nd and 3rd heavy infantry brigades of Czechoslovakia, although the Polish army has been strengthened a lot with the help of the United States, but the long-term chaos and changes in national ideology have made the Polish army's combat effectiveness very poor, and it cannot fight a tough battle, after encountering the thunderous attack of the Zess army, the Polish army division was almost completely annihilated, the whole division lost more than 1,900 people, and more than 3,000 people were captured. What is even more exaggerated is that the fleeing Polish army was not fully assembled within a week.

Of course, not all German-Polish troops were defeated, and the German 9th Model Panzer Brigade also fought a bitter battle with the 1st Heavy Mechanized Infantry Brigade of Czechoslovakia, which was also a direct confrontation between the German Leopard 2A6 tank and the Chinese-made VT-4. It turned out that the Leopard 2 tank was slightly inferior to the VT-4 in terms of firepower, maneuverability and defense, but the gap was not enough to make the battlefield one-sided.

The German 9th Model Panzer Brigade had a numerical advantage in tanks, and launched a blitzkrieg operation against the 1st Heavy Mechanized Infantry Brigade of the Zeis, and the Zess mechanized troops almost failed to withstand it, but after the rear command continuously put reserves to resist the invasion of the German armored troops, it finally maintained a rough balance of power on the battlefield.

The Germans used more powerful artillery to provide good cover for their armored troops, and the Genes side suffered a lot of damage because of the German artillery bombardment, but the front commander of Czechoslovakia, who had studied at the Chinese National Defense University, played a very Chinese tactic, sending a tank battalion to cross the German flank from the left flank at a critical moment, and wanted to cut off the German rear, which made the conservative Germans have a sense of crisis, and finally stopped the battle and retreated from the front line when they achieved a certain battlefield advantage.

Relying on a dangerous move, the Thiess side held the front and avoided the rapid advance of the German army into Prague, providing time for Czechoslovakia to mobilize and deploy national defense forces.

NATO's European Theater Command has also seen from these battles that it is impossible to completely subvert Slovakia without mobilizing a large enough force, and a larger offensive is brewing.
