The Soviet Union openly sent troops to Mongolia in disregard of the warnings of the Tang Empire, occupied one-third of the land, and exchanged fire with the Federation Squadron several times, causing certain casualties.

The Tang Empire was shocked, and Zhang Meng personally called Stalin and threatened to use nuclear weapons against the Soviet Union, but Stalin was not afraid and countered with underground nuclear tests.

This is the first underground nuclear test in human history, which shows that the Soviet Union's nuclear test has been transferred from the ground to the underground, which has a certain degree of concealment, so that the Tang Empire cannot lock the underground nuclear facilities of the Soviet army, and the action is fearful.

However, Zhang Meng was tough and ordered the nuclear missile silos in the major theaters of the Tang Empire to enter a state of first-level combat readiness, and all strategic nuclear bombers were put into the air and on standby. At the same time, Stalin also ordered all nuclear missile silos throughout the Soviet Union to be opened, and strategic nuclear bombers to be put into the air and ready for readiness.

At this time, the Tang Empire was in an advantageous position in nuclear armaments, and was the only country equipped with intercontinental ballistic missiles, and the United States and the Soviet Union were still in the process of catching up and stepping up research and development. At this time, the Soviet Union was still struggling in the process of developing ICBMs, after all, technology and funds were insufficient, and it was even slower than the United States.

The Tang Empire has installed 40 intercontinental ballistic missiles, which can carry nuclear missiles directly to Moscow, while the Soviet army's nuclear missiles have a maximum range of only 4,000 kilometers, which cannot hit the capital of the Tang Empire. The only nuclear weapons that the Soviets could threaten the capital of the Tang Empire were their strategic nuclear bombers, which could fly directly over Chang'an for nuclear bombing.

But the serious problem in front of the Soviet nuclear bombers was that they were still in the first generation, that is, propeller long-range bombers to carry nuclear bombs at subsonic speeds. The nuclear strategic bombers of the Tang Empire have bought second-generation jet long-range bombers to carry nuclear bombs, and the two sides fly to each other at the same time, obviously Moscow was destroyed first, but Chang'an may not be attacked, because the Tang Empire not only has an absolute defense circle, deploying a large number of interception fighters, the second-generation Raptor installed by the Datang Air Force has been equipped with advanced air-to-air missiles, and it is difficult for subsonic strategic bombers to break through the absolute defense circle of the Tang Empire. This is also the root of the Tang Empire's fearlessness.

However, Stalin's ghost, he knew that the nuclear threat to the Tang Empire would not achieve much effect, so he took the initiative to call Zhang Meng, saying that if the Tang and Soviet nuclear war were to be carried out, the Far Eastern territories of the Tang Empire and military bases in East Asia would be destroyed, and at the same time, hundreds of millions of Chinese in federal China would also suffer.

This really poked Zhang Meng's weakness, the Tang Empire could not ignore the lives of hundreds of millions of colleagues in federal China, so Zhang Meng fought back forcefully, if the Soviet Union dared to use nuclear weapons. The Tang Empire will wipe the USSR off the face of the earth at any cost.

Stalin believed that the Tang Empire had this ability. But his purpose was also achieved. Subsequently, he proposed that neither the Tang nor the Soviet Union use nuclear weapons, and that only a local war with conventional weapons be fought in Mongolia.

Zhang Meng smiled bitterly, he couldn't imagine that the local war would come like this, but he was not afraid. Agree immediately. Therefore, the Tang and the Soviet Union respectively promised to control the scale in the Mongolian region, and if one side was completely driven out of Mongolia, they would declare an armistice, and would not expand the war.

Stalin snickered, he believed that the Soviet Union had taken advantage, after all, the Soviet Union bordered Mongolia, and the powerful ground army of the Soviet Union was like a torrent of steel, which would crush everything.

But he ignored the fact that Mongolia is full of steppes and deserts. It is indeed suitable for large-scale battles in tank clusters and artillery clusters, but the Tang Empire has helicopter gunships, and the Korean War has shown that the Tang Army's Shenbow helicopter gunships are a one-sided slaughter of ground troops, and have won the title of tank killer. And the Soviet army was still blank in terms of helicopters at this time, and it was obvious that it would suffer a big loss.

But Stalin still didn't care. He listened to the report of the Soviet army, which temporarily converted the anti-tank gun into an anti-helicopter gun, which could fight the helicopter gunships of the Don Army.

Tang and the Soviet Union tacitly agreed not to use nuclear weapons, to control the scale of the war in Mongolia, and to fight a local war, all in order to make a name for themselves and see who is the world boss.

Soon, the Far Eastern Theater of the Tang Empire mobilized 300,000 troops, entered China by rail, and assembled towards Mongolia.

The Soviet army was very shameless, taking advantage of the fact that the Tang army had not yet arrived in Mongolia, and took the lead in attacking. The tank cluster and artillery cluster of the Soviet army continued to fight with the tank cluster and artillery of the squadron, like two torrents of steel colliding together, which was very tragic.

In just one week, the Soviet army fired 1 million tons of artillery shells, dispatched 20,000 sorties, destroyed more than 2,000 tanks and combat vehicles, and more than 100 aircraft, causing 30,000 casualties.

However, the combat effectiveness of the first army is also very strong, the mixed formation of the Kuomintang and the Communist Party, and the support of the advanced weapons and equipment of the Tang Army, also caused the Soviet army to lose more than 1,000 tanks, more than 80 aircraft, and more than 10,000 dead and wounded.

As soon as China and the Soviet Union fought, they suffered losses, and the main reason for this situation was that the Soviet army had powerful artillery units, especially the Katyusha rocket artillery unit, and the large-scale covered artillery bombardment was the real reason for the casualties.

On the contrary, in terms of air combat, although ** was inexperienced, he did not suffer a big loss. This also has something to do with the fact that the Tang Empire attaches great importance to the navy and air force and ignores the ground forces, and completely inherits the combat ideas of the Tang Army, so weapons such as Katyusha rocket artillery are not good at it, which caused the situation of suffering losses in the first battle with the Soviet Army.

Relying on the strong ground firepower superiority, the Soviet army seized a third of the land in one fell swoop, constantly forcing the ** back.

While scolding Stalin for being shameless, Zhang Meng urged the Tang army to rush to the Mongolian battlefield as soon as possible, find a way to stop the Soviet army, not lose this local war, and maintain the status of the boss of the Tang Empire.

On the one hand, they quickly transferred to the major airports in Inner Mongolia and urgently engaged in the Mongolian air battle, and on the other hand, the Tang Empire itself sent a minelaying aircraft formation to arrive and lay mines in the air directly in the air between the Chinese and Soviet armies to stop and delay the Soviet army's offensive speed.

A large number of Soviet tanks and combat vehicles were blown up during the assault, causing heavy losses and casualties.

At the same time, the Tang Army's Blue Fox Special Service Team landed in Mongolia, and they used long-range sniper rifles to accurately shoot and kill Soviet minesweepers, making the Soviet Army exhausted.

The Tang Army finally won valuable strategic time to transfer troops, and a large number of Tang Army ground troops marched into Mongolia during this time, and ** also retired and redeployed, redeployed the operational policy, beware of the Katyusha rocket artillery units of the Soviet Army, and formulated countermeasures.

During this period, the Tang Army continued to lay mines in the air, and they went out at night to scatter mines everywhere in the areas controlled by the Soviet troops, so that the rear camps of the Soviet troops were not at peace, and the supply lines were also in difficulty.
