While it has begun slowly to adapt, Ukraine’s military is still deeply rooted in Soviet-era offensive tactics and culture, centralizing decision-making at the top while penalizing subordinate soldiers who dare to deviate from the plan.
When the propaganda was still "Ruzzia is losing hard" of course they blame said losing on "being rooted in Soviet era" and Ukraine winning on NATO training and equipment. I bet we will soon read some galaxy brain claiming "Russia learned from NATO while Ukraine didn't" because of course NATO is when winning.
That's the eastern Europe for you. In postsocialist countries, even after over 30 years of the destruction of socialism, literally every failure gets blamed on socialism.
