russia used this war to modernize their war machine and create new doctrines that are unmatched in the west. they went from "tank rush" from the beginning of the war to drones being used to improve their artillery to centimetres of precision and destroying 5m usd tanks with 50 usd toys. a historical comparison would be the prussian war on the danes. this war complete revolutionised their tactics and allowed them to defeat the austrians and the french while the rest of europe was still studding napoleon tactics.
