Fifteen kilometers north of Elliano is the U.S. military's defense zone. It's just that this is not a key defensive zone for the U.S. military. In order to avoid being divided and encircled, the U.S. forces shrank their forces to the vicinity of San Luis Potosí. The core of the defensive line, also fifteen kilometers south of San Luis Potosí. The U.S. military deployed most of its troops and equipment to these lines.

The line of defense between the Panuco and Santiago rivers of the American army is two hundred kilometers long. And San Luis Potosí is the heart of this defense. The entire route consists of anti-tank trenches, infantry trenches and communication trenches behind it. In front of the anti-tank trenches, anti-tank mines were also laid, and in the infantry trenches, a number of anti-tank guns and anti-tank guns were deployed. This qiē was all in response to the attack of the armored forces of the squadron. Whether or not these fortifications can be used to resist the attack of the squadron's armored forces, in fact, the US military has no bottom in their hearts, and they mostly use this battle as a real site to test the ability of these anti-tank weapons, so that they can be applied to the Rio Grande defense line in the future. It can be seen from this that the US military no longer has the confidence to stop the squadron in Mexico.

At eight o'clock in the morning of August 23, the 2nd Army of the Chinese Army was ready for the offensive. All tanks and armored vehicles of the armored brigade of the 2nd Army were ready for action, and two additional infantry divisions were in force. The mercenaries also deployed ten divisions to cooperate with the 2nd Army's attack. According to the predetermined plan, today's attack will advance directly beyond the core line of defense of the US military. Although this distance is seventy kilometers, it is not very difficult for armored forces. At the same time, the U.S. military did not deploy too many troops in this area, and the resistance was not too fierce.

Behind the 2nd Army, hundreds of large-caliber artillery pieces were ready, and as soon as the order to attack was given, they would rain artillery on the enemy in front, destroying the rudimentary lines of the American army and clearing the way for the attacking troops.

"Marshal, it worked! Our fleet has managed to blow up the airfield near San Luis Potosí, and most of the U.S. warplanes have been blown up on the airfield. Air supremacy in northern Mexico is ours! General Feng Yong, deputy commander of the Air Force, happily reported to Marshal Zhao Bowen. After successfully blowing up the field airfield of the US military, the Air Force has already sent a message to the command.

"Haha! It's so good! The American warplanes were destroyed, and for a long time, they interfered with our bombing! Marshal Zhao Bowen was also very happy. When the infantry is attacking, if there is the cooperation of the air force, it can often achieve twice the result with half the effort. With the support of the air force, the infantry can get good cover when attacking, and the casualties will be much smaller. After the U.S. military sent a large number of fighters into Mexico to fight, Marshal Zhao Bowen was worried that the U.S. military would affect the air force's support for infantry. Well, now, this trouble is finally solved.

"The casualties among the pilots of the Marshal American Army were also heavy. At least for the next month, they don't have the strength to compete with us for air supremacy in Mexico! Lieutenant General Feng Yong said. The success of this bombing has also accumulated a wealth of experience for the Air Force, and when similar operations are carried out in the future, the chances of success will be much greater.

"One month is enough. By then, I'm afraid we'll have made our way to the Rio Grande! Marshal Zhao Bowen said. Although there are still hundreds of kilometers from the Rio Grande, at the same time there are still the lines of defense of the American army in front of them to break through. But time is still very abundant for the squadron. The U.S. military in Mexico is running out, and as long as it breaks through the line of defense in front of it, the rest of the journey will be smooth.

"By the way, what about our casualties?" Marshal Zhao Bowen asked.

"Our casualties were not significant, in total eleven aircraft were lost. Including 4 FB 'Hai Dong Qing, 3 UB' Hongyan, bombers and 4 FH5' Falcon, dive bombers. All shot down by anti-aircraft fire from the Americans! Lieutenant General Feng Yong said. Such a loss is already very small compared to the bombing of more than 100 US fighters.

"Hmmm! Let the pilots have a good rest, and from tomorrow we will need to launch a large-scale offensive against the American defenses. When the time comes, the Air Force will also be involved in the offensive! Marshal Zhao Bowen said. The loss of eleven planes made him feel a little distressed. However, compared to the results achieved, this loss is also completely acceptable.

"Yes, Marshal! The Air Force is guaranteed to be able to complete the mission! Lieutenant General Feng Yong said firmly.

"The offensive begins! The Air Force has gained air supremacy, and it's up to us next! "Marshal Zhao Bowen gave the army an order to attack.

At 8:05, hundreds of heavy artillery of the 2nd Army began shelling, and the dense artillery fell on the positions of the American troops, bursting into clusters of orange-red fire. The positions of the American troops were covered in smoke, and at the same time the dry land was splashed with patches of dust.

The shelling was over in less than ten minutes, and the U.S. forces did not have many troops deployed at the front line, so there was no need to waste too much artillery. In fact, after the end of the ten-minute shelling, the rudimentary positions of the American army at the forefront were in shambles. Shallow trenches were blown up, as were some of the fire points of civil structures. However, this did not cause many casualties to the US troops. Because of the number of troops deployed by the US army and on the front line. As early as when the squadron showed that it was going to attack, all these American troops withdrew from their positions.

"Immediately send a telegram to the headquarters, the Chinese launched a fierce shelling of us. They've attacked, and we can't stand it! A brigadier general commander commanded the signal corps.

When the signal corpsmen sent out the telegram, the Brigadier General of the US Army had already given the order for the entire division to abandon its position and retreat. Although they had not yet received an order from Admiral Davis to retreat, they did not want to hold on any longer. Fools know that when there are not enough troops and equipment, they can resist the attack of the armored forces of the Chinese army with their flesh and blood.

After the end of the shelling of the 2nd Army of the Chinese Army, the armored brigade launched a charge. tb

'Cheetah, the battalion of medium tanks became the vanguard of the whole brigade, and the flanks were TP' Wolves, light tanks. Behind the three tank battalions, there were two mechanized infantry battalions. The wheeled armored vehicles of the two mechanized infantry battalions, as well as the infantry carried inside, will provide cover for the tank units. In addition, the 2nd Infantry Division of the 14th Army followed. It was followed by the 21st Infantry Division and ten divisions of the Riben Mercenary Army.

"Crunch, crunch" tank tracks crushed across the ground, making a somewhat tooth-sour sound. The assault force, composed of armored brigades as the vanguard, rushed to the positions of the American troops. However, until the tracks of the armored forces crushed the American defenses, they did not meet any resistance. The U.S. troops defending the front-line positions had already fled.

This point did not surprise the squadron. Because this is not the focus of the U.S. military's defense, it's just a place used by the U.S. military to monitor the squadron and confront the squadron. Once the squadron launches an attack, only these small forces of the US army will definitely be able to resist the squadron's attack. In order to preserve their strength, retreat became their only option.

"Marshal, the American troops have retreated, and our assault forces have not encountered any resistance at all!" General Xie Dingkun, commander of the 2nd Group Army, reported to Marshal Zhao Bowen.

"Ordered the assault force to continue to the north. The real big battle is on the line fifteen kilometers south of San Luis Potosí! The troops keep up, don't let the assault force go deep alone! Marshal Zhao Bowen ordered.

"Yes, Marshal!" Admiral Xie Dingkun nodded. Then another 5 infantry divisions of the 2nd Army and units directly under the Army Group set out. The remaining dozens of divisions of the mercenary army of the Ritben also followed. The 8th Army, which was a reserve, and the other 30 infantry divisions also advanced in turn. As the assault forces advance north, the entire front will also be shifted north.

After the 2nd Army launched an offensive, the 7th Army, with the cooperation of Korean mercenaries, also attacked the attacked. Similarly, the U.S. forces across from them retreated with little resistance. Maybe they knew that in the absence of strong fortifications, they could not resist the attack of the squadron at all, so they were not prepared to waste their troops.

The armored forces of the 2nd Army of the Chinese Army were fist assault troops, and the speed of their advance was very high, which was the reason why the armored forces slowed down in order to wait for the follow-up infantry.

Otherwise, the advance rate of armored forces can be as high as ten kilometers per hour. At a time when the US military does not yet have weapons capable of threatening armored forces, there will be no problem with such a surprise attack. However, when the US military has developed a series of anti-tank weapons, the armored units cannot attack blindly, and they need to be protected by infantry when they go deep alone. Otherwise, tanks and armored vehicles of the armored forces will also be the target of massacre by the US military. Of course, the premise is that the anti-tank weapons of the US army can be good and can penetrate the armor of tanks and armored vehicles of armored forces.

Even so, at 4 p.m., the armored units of the 2nd Army had broken through to less than 10 kilometers south of San Luis Potosí, with the American forces on the verge of collapse. At this time, Marshal Zhao Bowen ordered the troops to stop the offensive and defend on the spot. Start preparing for tomorrow's massive offensive! ，
