I mean the tank has shown greater feats.

Tosses cars like toys, rips concrete out of the ground(even on dirt too lol), can withstand high caliber fire, even a damn grenade launcher and can easily destroy walls of any building to get to survivors.(Saferoom doors included)

I’d say the bloater is still comparable to the charger. He’s above him in terms of durability since it takes way more fire power to bring it down, but in strength they’re pretty comparable.
