Although the Golden Eagle 4 is inferior in range and firepower density, in terms of flexibility and weapon power, the Golden Eagle 4 can have an absolute upper hand. With the help of optical sights, the cannon power of the Golden Eagle 4 fighter was brought into full play, while the Boston Air Force, which used mechanical sights, could only make up for the lack of accuracy with the firepower density of the 12.7 mm machine gun.

In the air battle, the situations that Fang Xiaoyu had foreseen appeared. If you use a jet to fight a propeller plane, with a much higher performance, some problems will not be exposed, but in a jet duel it is different. The Air Force pilots of the Imperial St. Martin have been secretly training in the Chinese Empire, and they have been training for up to two years in major aviation schools and the 1st Air Force Division, and they are well versed in the performance and use of jet fighters.

Those Boston Imperial pilots are different, because the F84 fighter jets have been equipped in large quantities for less than a year, and the Boston Imperial Air Force has no experience in using jet aircraft before, they are all based on the operating experience of propeller aircraft, and slowly explored.

In the early days of the F84 fighter's entry into service, many ace pilots flew planes according to their usual habits, but as a result, there were many accidents, many planes were dropped, and two ace pilots were killed. In this way, with the accumulation of experience little by little with the lessons of blood, the Boston Air Force slowly mastered the operation method of jet aircraft, and this can only master the basic operation methods, and the air combat tactics belonging to jet aircraft cannot be created in a short period of time, so compared with the Chinese Empire, the Boston Air Force is still at the level of primary school students.

The Imperial Air Force of China, which has many years of experience in the use of jet aircraft, is different, they have a complete jet trainer, and they have a ground flight simulator designed by Xiaofeng, and it is very easy to complete the training.

The Boston Empire went to great lengths to select the elite from a large number of active pilots and train thousands of qualified jet pilots for use in a year. However, the Chinese Empire is training jet pilots in batches at a rate of more than 4,000 people a year, and these people can also learn complete air combat tactics and be corrected some bad operating habits, so the gap between the two sides in the quality of pilots is actually greater than the gap in fighter performance.

In general, the gap between the pilot's skill and the performance of the aircraft smoothed out the numerical gap between the two sides, and the numerically superior Boston Air Force and the St. Martin's Air Force fought for a long time, which was considered a draw, but those bombers were unlucky.

Although the B29 group quickly increased its flight altitude and threw the lightning fighters below, those dense rockets still caused them a lot of trouble, especially in order to reduce weight and climb quickly, most of the B29 bombers threw away their bombs in advance, and only a dozen bombers bombed and dropped bombs at high altitude, and the accuracy of high-altitude bombing can be imagined.

This operation greatly angered the Boston Air Force, losing more than 90 B29 bombers and more than 40 F84 fighters to complete the mission, which greatly annoyed the military, which had great hopes for F84 fighters.

The Boston Empire had long known that the Chinese Empire had jet planes, but the news was kept strictly secret so as not to cause panic, and now that they learned that the St. Martin Empire was equipped with a jet aircraft with slightly better performance than its own, the government naturally knew that this was the kind of jet aircraft of the Chinese Empire, so the government asked the aircraft factory to speed up the final flight test work of the new F86 fighter, and at the same time asked the aircraft research institute to speed up the design of the new YF104 fighter.

The defeat in the first air contact infuriated the Boston government, and in order to save face, Washington III ordered the Axis bloc to go to war in an all-out way, attacking NATO from all directions, and the first to give priority to the Axis bloc was the Southern Subcontinent.

The southern subcontinent has always been an area to be developed, and even with the policy of the Chinese Empire, in only a dozen years of development, it will not be able to completely develop all the occupied areas, at most relying on the newly built coastal railway lines, which will extend more than 200 kilometers inland from the coast as the center, and the colonial development of other countries is only a scratch in the surface. Therefore, in the middle of the entire continent, there are still large areas of primeval forests and undeveloped areas, and even expeditions are very dangerous to enter, and it is simply unrealistic to want to pass through large forces.

If it wanted to fight on the southern subcontinent, the Boston Empire had only two directions of attack, one was the Cape Town region in the south, and the other was Alexandra in the northernmost part of the continent.

If it was to Washington III's liking, he should attack the Cape Town area first, after all, the Chinese Empire had discovered rich gold and diamond minerals there, which he had always coveted, but the military considered the overall strategy and believed that it was most important to control the entire Mediterranean Sea first, so the Alexandra region became the main direction of attack.

In order to ensure military superiority, Boston transferred more than 50 heavy armies and eleven air wings, and even the Axis Combined Fleet in the Mediterranean, which had six battleships and one aircraft carrier, was asked to cooperate with the army's operations. For a time, the pressure on the Southern Military Region increased greatly, and Cai Tingyuan had to mobilize heavy troops to the Alexandra region to prepare for defensive operations, and the Mediterranean Military Region commanded by Gao Hong was also ready to support the Southern Military Region at any time.

The Mediterranean Fleet of the Chinese Empire, which had only eight cruisers and twenty-one destroyers, decided to cooperate with the army for defensive operations, but even so, Cai Tingyuan could only draw ten desert light armored corps, three mountain infantry corps, five mechanized corps and two heavy armored corps, and the air force had three fighter wings and two bomber wings, and these were all Wehrmacht units, and their combat effectiveness could not be compared with that of the Guards.

Although Fang Ruijun wanted to transfer some troops from other regions to support the Southern Military Region, the Axis countries were waging a full-scale war, and the pressure on each military region was very great, and he could not do anything, and the Guards Army could not be used casually. Because Fang Ruijun knew very well that once the offensive of the Axis army was tired, the Guards were the best weapon in his hands to launch a counteroffensive, and before that, the sword was to be hidden in the box, so as to give the enemy the greatest deterrent and make the other party have scruples, which was more advantageous than putting the strategic force of the Guards on the table.

Although the troops in his hands were less than half of the opponent's, Cai Tingyuan was not worried, because he had always been a surprisingly victorious person. When attacking the defense line of the Lena River, he attacked the 100,000 Cossack regular army with two armies, which had a geographical advantage, and also defeated the other side with a surprise night crossing, so he became famous in the first battle.

In the face of a strong Axis army, he thought not of pressure, but of an opportunity to defeat the other side. If he can win a big victory at the beginning of the war, the effect on the morale of the people is immeasurable.

The Boston Empire had just changed its military rank system, and this time the commander of the Axis Southern Army was Mike, who had made a big splash in the amphibious war in The Hague, and of course he was now a four-star general.

The high-spirited four-star Admiral Mack did not take the Southern Army of the Chinese Empire seriously at all, and in his logic, the combat effectiveness and equipment of the army serving in the colonies should be the worst, and they were not vulnerable at all. So he split his forces into two arrows, one to attack the port of Alexandra and the other to the city of Cairo.

Seeing that the other party divided his troops, Cai Tingyuan decided to eliminate one of them first and hit the opponent's morale. To this end, Cai Tingyuan ordered the Second Desert Light Army and the First Mountain Infantry Army to hold on to Alexandra Harbor to provide conditions for the main force to encircle and annihilate its southern route troops, and the tragic defense of Alexandra Harbor began.

It was impossible to build a solid enough position in the endless desert, not to mention that the defenders did not have an advantage in artillery fire, air force or even navy, so Commander Cheng Guangling, who was in charge of the defense, decided to shrink all the troops into the city and rely on buildings to engage in street battles with the enemy.

The high-spirited Axis Army Commander-in-Chief Mike was greedy, and in order to get more credit, he decided to take command of the capture of Alexandra Harbor first, and then the attack on Cairo.

For this reason, at this time, the Axis North Route Army was personally commanded by General Mack, who led a powerful attack force of twenty-three heavily armed troops, relying on the high-speed advance of mechanized troops, and arrived at the outskirts of Port Alexandra in only two days.

Despite being a lightly armed army, the Second Desert Light Army also has a large number of self-propelled artillery pieces of various types, among which the Storm Bear 2B 240 mm self-propelled howitzer and the 103 mm 40 barrel Storm Bear 2E self-propelled rocket launcher are absolute killer weapons.

A dense rain of bullets hit the unprepared vanguard of the Boston Army, enveloping an armored division in a barrage, and by the time the Chinese artillery bombardment was over, the place had been blown to pieces.

Because of the existence of artillery sighting radar, the accuracy of the artillery units of the Chinese Empire is quite high, and the relatively concentrated falling shells greatly increase the lethality, and under the same number of artillery attacks, the artillery attack efficiency of the Chinese Empire can be doubled.

The ground on the outskirts of the city is relatively flat, and there is simply no place to hide the damage. In this case, the relatively light and thin armor of those M4 heavy tanks and Hellcat tank-destroyers, how is it an opponent of large-caliber artillery. In just a few minutes, an armored division could already announce the cancellation of the number, but fortunately, the large-caliber artillery in the Axis forces was towed, and they escaped this because of their slow movement.

Annoyed and angry, Mike immediately ordered the air force to bomb Alexandra Harbor, and soon a large number of B29 bombers were in the air, and the whole city was turned into a sea of fire in a series, but various anti-aircraft fire on the ground also gave them a solid blow, and the super-mobile vehicle-mounted anti-aircraft guns were quite agile, and they shot down more than thirty Axis bombers under the operation of the soldiers.

The infantry soldiers of the Chinese army were fully prepared for the bombardment, and they relied on the underground waterways and the subway system to skillfully evade the air raids to minimize casualties, and the self-propelled guns were also driven into the subway stations to take refuge.
