Why did Ukraine's sudden counterattack deviate from the chart and the counterattack began to approach the Ukrainian-Russian border?

Ukraine's combat effectiveness was not suddenly surpassed, but it was ready two months ago.

First, Ukraine has received a lot of material, military and information support from NATO led by the United States. For example, all actions of the Russian army are under the control of Ukraine. On the other hand, Russia simply cannot grasp the movements of the Ukrainian army.

Second, there is another reason for the combat effectiveness of the Ukrainian army in off the charts, that is, the United States provided a long-range attack on the "Hippo" rocket launcher, and the European Union countries provided a large number of advanced weapons, which fundamentally guaranteed Ukraine's combat effectiveness report. Ukraine is also a fighting nation, and they always think that they are defending their country in this war. It is completely possible to die for the country, which is also the fundamental reason for the improvement of Ukraine's combat effectiveness.

Third, the internal strife in Russia has reached a white-hot stage. The latest manifestation of this kind of infighting is the successive deaths of senior officials in the Russian energy sector, and this kind of infighting has probably spread to the army. Otherwise, the Russian air force and army have no support this time, which is a bit abnormal.

Fourth, Russia itself is seriously short of troops. Russia itself has always wanted to regard this war as a special military action and does not want to expand the scale of the war. Therefore, in the whole Russian-Ukrainian war, Russia only sent100000 people. Several people scattered in a place as big as Ukraine carried out a large-scale attack on Ukraine. Lay the place still have to stay, natural shortage of troops.

5. The Russian army itself is backward in information technology. Since the Russian-Ukrainian war, many Russian generals have died. In modern warfare, the death rate of Russian generals is definitely the first. This is essentially because Russia's own information technology is backward, and generals have to use civilian facilities for communication or personal command at the front, resulting in the extremely high mortality rate of Russian generals. The same is true of this counterattack in Ukraine.
