Avdiivka was fortified for 8 years and it was hardest to crack. Any further defense line built in hurry will be easier and easier? . Stories about some purposely slowing down Russian Army is good night stories I think . Reality is that Ukrainian army is throwing into the battle everything they have, including Abrams and Leopards which were kept in deep reserves, but they have no choice as they are running out of armour. "No-one likes an early pullout but sometimes it's necessary to avoid unwanted consequences." Like at Avdiika debacle The Ukrainian high command needs sacking! Or better a firing squad for this debacle!!
