The Royal United Services Institute of Defense and Security recently released an internal Russian document decrypted the Russian army prepared four major scripts before the outbreak of the Russian-Ukrainian war. The four major scripts include: the first large-scale missile assault, the second large-scale air strike, the third special forces operation to seize key points, and the fourth, the Russian military armored mechanized force will gain control of Ukraine in 10 days, completely control the entire Ukraine by August, and complete all combat plans.
The Russian army planned to win quickly with a fast blitzkrieg, and achieved a decisive victory before the United States responded. The Russian army will quickly seize all infrastructure, including electricity, nuclear power plants and financial institutions, etc.

At the same time, the Russian army mechanized troops , paratroopers and special forces attacked three routes. The Russian army mechanized troops suddenly rushed toward Kiev on multiple routes on the ground. The Russian paratroopers seized the airport to receive the Russian heavy paratrooper division landed. The Russian special forces infiltrated into Kiev and captured the Presidential Palace. The Russian army quickly captured Kiev and the pro-Russian faction took control of Kiev, which became the key to this blitzkrieg.
However, the four major plans of the Russian army were actually unsuccessful. The battle has been more than 9 months. The Russian army has not even touched the suburbs of the Ukrainian Twin Cities, the core position of the Ukrainian army in the Donbas region. The Russian army also continued to fight hard in Bachmut, Malinka and Akadivka on the outer circle of the first-level position of the Ukrainian army in Donbas.

First of all, there was a serious intelligence leak before the Russian army started the war, which is very important. According to the US "" report, in October 2021, the CIA had obtained information about the Russian army's war. The United States believes that the Russian army will launch a large-scale operation to seize most of Kiev, leaving only a small piece of land in the west for Ukraine.
In November 2021, the United States forwarded the intelligence to the Ukrainian side, and said, "Guys, dig the trenches quickly. We are serious, you will be attacked on a large scale soon."

However, Ukraine has never believed that the Russian army would raid Kiev because the roads around Kiev are not conducive to large-scale corps combat. How could the Russian army cross the Chernobyl nuclear power plant polluted areas to launch a large-scale armored attack? The Ukrainian military insisted that the Russian army would only launch a local battle in the Donbas region.
Within the NATO group, France and Germany do not believe that the Russian army will launch a large-scale attack. Because on the border, the Russian army gathered more than 100,000 people. How could it be possible to launch a large-scale war? There is not enough troops? Putin must be just putting on the airs and scaring you what you want to get. However, the United Kingdom and the three countries of Baltic said they believed it.

At the end of 2021, the US intelligence department told Ukraine that the Russian army will cross the north from Chernobyl to attack Kiev, and the Russian special forces will attack the Presidential Palace. The battle will break out in winter, and the Russian army plans to capture Kyiv in 4 days. At the same time, the Russian army will also dispatch from the east to the eastern part of Ukraine and attack until Dnieper River. The Russian army on the southern front will set out from Crimea to capture the entire Ukraine coastal area.
However, the Ukrainian military still does not believe it. The Ukrainian military still believes that the Russian army’s target is Donbas, not Odessa and Kiev, and the main force of the Ukrainian army continues to assemble to Donbas. However, the Ukrainian army carried out a large-scale evacuation of the command nationwide, radar . Just in early February, most of the Ukrainian command agencies and troops had left the barracks and deployed in the field. Later, large-scale missile assaults in the early stages of the war were all shot empty houses.
However, after the Ukrainian military deduced through war chess, it still believed that the Russian army could not dispatch large corps to attack Kiev, because the reason was that the bad road situation could not be supported. To this end, the Ukrainian army continued to increase troops to the Donbas area until the war broke out on February 24. Half of the Ukrainian army's troops were in the Donbas area, with empty troops in the rear, and there were only two brigade defenders in Kiev.After the war started, the Russian army set out from Crimea was very smooth. They seized the weak Ukrainian Khelson and Zaporoze , but they hit hard nails in Mariupol , and the Russian army's southern line was forced to slow down.
is on the northern line, and the Russian army is also very smooth. It attacks the periphery of Kiev at once, and the Russian paratroopers also successfully control the Antonov airport in Kiev. Everything seemed to be going well, but on this day, a Ukrainian militia battalion happened to practice shooting at the airport. It was this militia battalion that withstood the Russian elite paratroopers special forces.
Then several Ukrainian rocket launchers suddenly covered the airport runway, and the Russian army failed to seize the airport. When the Russian armored troops launched multiple raids, Ukrainians along the way used drones, roadside probes, etc. to quickly transmit various Russian military intelligence to the Ukrainian army command. At a Ukrainian artillery training center in Kiev, teachers were used as officers and students pulled out an artillery brigade for the artillery to occupy the periphery of Kiev. Based on intelligence, they continuously and accurately bombarded the Russian armored troops on the road, defeating the Russian army's multiple ground attacks.

At this time, the Russian army's logistics problems also occurred. The convoy of more than 60 kilometers was in traffic jam for nearly a week. More than 200 Ukrainian ambush groups appeared behind the Russian army, and the entire Russian army was in serious logistical difficulties and it was difficult to launch a strong attack on Kiev. In early April, five Russian armies were forced to evacuate the periphery of Kiev.
