The way the Ukrainians are expending armor , a local source sounds good.
Poor Ukes, they gain ground, but alas, along with gained ground is a longer supply chain. Uke reinforcements are blown up before reaching their front line troops, who are then isolated and dispatched.
No air cover for the Ukies .Suicide missions. Yay team
In February of 2022 nobody dreamed that we be talking about Ukraine’s supply train and combat offensives 17 months later.
