There’s a problem with legged machines in that they tend to be heavier, require more maintenance, and have a higher ground pressure for the same task/payload as an equivalent wheeled or tracked vehicle.
While there’s some terrain where they’re more effective (mountains), that’s fairly limited. Plus, if the terrain is too extreme then even legged machines can’t get through, so you’re looking for a goldilocks zone for deployment.

I get it’s a joke, but there’s a point.
Modern (western) tanks have tons of safety systems in them, from fire suppression to safe inert storage for ammo and fuel. In theory there’s areas where the newer M1 tanks can be hit and penetrated and it can continue operating. And even if it’s hit in a spot where the tank is disabled, the crew have a really high survival rate.
And if you’re wondering why I specified western tanks, it’s because of Russia. All the tanks they have in operation right now have issues with the entire ammo magazine blowing up when hit, which tosses the entire turret into the air and kills the crew
