Russia used to have the second most powerful military in the world.
Now they have the second most powerful military in Ukraine.
We'll see how that turns out.
As to the offensive, defenders always have an advantage over attackers. Remember Pickett's Charge. Or Fredericksburg, for that matter.
The “most” powerful military on earth is now effectively out of 155 shells and can’t even support live fire training in its own units. While the “second most” powerful military in Ukraine fires ten thousand or more a day of its equivalent shells and is churning them out at a rate not seen since WW II.
