> US military doctrine states that an invading force needs a 3:1 attacker:defender ratio. Russia went in with the inverse of that and is still winning. What do we define as winning here?, Ukraines tactic is to fall back to defensive positions when they are about to lose something so not to lose men. The gains Russia has made are very small and the amount of equipment and men it has taken to make them is huge. Most of those games where made before long range heavy western weapons started being delivered too, I suspect their gains will slow down even further because of this.
