There is hardly a battle in history without casualties and loss of materiel. Your assertion does not prove as much as you might think.
Why are you so over confident that you mock someone else’s personal experience, without providing systematic evidence? There is a difference between anecdotes & individual examples, versus clear systematic evidence that Western equipment, doctrine and trained Western soldiers will not be effective when fielded against a peer enemy.
Also, if I understand correctly, Russia’s army has consistently outnumbered the Ukrainians. Ukraine is still struggling to prevent missile and drone attacks - because they do not have ENOUGH Western equipment to cover the South and the East.
Now, just for laughs -

“Why are you so over confident that you mock someone else’s personal experience”
He didn’t provide LINKS to prove his personal experience, so it’s meaningless, and given his attitude it’s probably lies anyway.
Good to see Nebraska is trying to catch up with Russia, but they have a VERY long way to go.
