yo that's a wild question lol. tbh, the in-game physics are super exaggerated for gameplay, right? like, no way a real creature could throw a car that far without some insane strength. a typical sedan is easily 1.5 to 2 tons. if the tank can lob those things, its strength is off the charts. i mean, its own weight would have to be pretty massive to anchor itself for those throws. makes me think it'd have to be at least 5 tons, maybe even 10 to throw cars like that. but yeah, it's total game logic.
