Defense experts in Britain say the part of the Russian army that is modern is not large, and the part that is large is not modern. The Russian advance attack in Ukraine has floundered, says this report in the WSJ. About 25% of the Russian army is made up of conscripts. The hundreds of billions of dollars spent on modernization of the Russian armed forces have been spread thinly, and dissipated also because of corruption and poor management. 

The Russian encrypted communications did not work as expected leading to relying on open communications that could be intercepted or jammed. The Russian government and president Putin were still stuck on 2014 and did not realize the determined resistance and the desire for independence of the Ukrainian people. Ukraine is a technologically advanced European country the size of Germany with a population of 40 million, and Russia has an economy the size of Italy, factors that also played a part. The corruption and poor economic conditions in the border Ukrainian republics setup by Russia led many Ukrainians in the eastern border region to question any advantages from Russian rule. The user of poorly motivated conscript soldiers led to many generals and other officers to have to be present on the front lines leading to Russian officer level casualties.

The use of antitank weapons supplied quickly from the European Union and the US, and use of small mobile units of Ukrainian volunteer and army forces to tactically destroy the front and rear of miles long convoys of tanks and armored vehicles - leaving the rest of the convoys trapped in between. Logistics also failed to resupply deep inside Ukraine as Russian forces depend on rail based resupply which could not happen without control of cities on the rail lines.

The volunteer forces in Ukraine after 8 years of war since 2014 and the immediate assistance with antitank and other military assistance from US, and EU, played a part in the western response to the Ukraine crisis and president Putin's actions.
