by the Russian forces. This means that the Russians push through defence positions of Ukrainians and create a corridor. The only thing this shows is classic out dated NATO Think Tank concepts of warfare. Logistics and the ability to move ammo, if there was ammo, become so fast by already standard lorries being able to drive way faster that in a terretory like Ukraine the corridor than just would be attacked from two sides.
The spear head strategy of NATO to fight WW3 was only to murder the spear head forces, namingly the race cheaters by Confed understandig of Big Red One. The German forces stationed close, by well able to imitate an American accent, were running Artillery and were selected to not hesitate using their canons while the heros kept the Russians bussy in the Thüringer woods, if we did not cut their throughts as Germans being realy good in their language, too, pushing our usual weekend brawls onto another level.
Way more dangerous for the average soldier in Ukraine is a Russian war machine gaining momentum and being able to take out positions over the entire stretch. This way every break through of defence is only a destruction of defence and the force will turn in one direction to attack close by positions from a flanking position, but not head to Kiev.
Wars, since the Germans slipped into Uniforms and way worse never faced appropriate punishement for their murder and plunderig campaigne, are wars of destruction and killing.
Iraq, Lybia and today also Gaza were all wrecked and during combat soldiers had little to no chance to surrender.
War is more than ever about killing the enemy fought by hardcores never surrendering.
