about that armor wrt HEAT: Due to the extreme hardness of the ceramics used, they offer superior resistance against a shaped charge jet and they shatter kinetic energy penetrators (KE-penetrators). The (pulverised) ceramic also strongly abrades any penetrator.
and its resistance to kinetic hits: several MlAl crews reported receiving direct frontal hits from Iraqi T-72s with minimal damage.
Is it going to be a walk in the park then? Not necessarily. That 60t weight is a liability in an area where bridges are built to support up to 40t tanks. And are Gen 3s sufficiently protected against topside armor attacks like what Javelins do? Israel lost some Gen 3 Merkavas in Lebanon in 2006, to Russian ATMsKornet ATMs. Then again Ukraine still has its old T64s and 72s in the fight and UA's leadership is generally well-regarded in how well they are able to use the vehicles they do have.
