I crabbed a tank, but he just laughed!?

This is news to me.

Today I threw my assault bomb on a tank while he was using juicing. The explosion certainly did some damage but he kept on moving and shooting things. I'm not used to pros moving and shooting after they've swallowed one a bomb.

Bloody tanks.

Is this intentional? Can anyone else survive them? I don't recall if he had an armour endorsement or not.

Juiced tank can survive headcrabs and airstrikes with the right armor and skill upgrades. The only guaranteed one hit kill in the game is a pancake.
