When this tank gets hit by a shell:

Why is there smoke coming out of your tank, Seymour?

Oh ho, no! That isn’t smoke, it’s steam! Steam from the steamed tanks we’re having! Mmm, steamed tanks!

can drink the water

As a tank maintainer, this is the least credible part of the post.

That would be such a flex. You’re driving through the desert with you tank full of water and people around you are dying of dehydration.

You can pee wherever/whenever you want.

Don’t die of spall, but die extra quick of shockwaves transmitted through water.
