For those saying that a mech shouldn't be able to destroy a tank with a single stomp... A tank (or for that matter most vehicles) are simply not designed to support that much weight. A 60 ton tank can't have an additional 60 tons placed atop its turret and survive the experience (let alone a 60 ton weight that's moving with any speed downward).
At the very least it would crush the turrent down into the vehicle (destroying any mounting structures), possibly even driving the armored turret thru the bottom of the vehicle (and that's assuming that the turret doesn't crush in addition). The sudden increase in weight and force would crush any suspension system (wheels, tracks and their drive shafts would be broken off or so horribly bent as to not function). Even if the occupants of the vehicle managed to survive, the weapons would be useless, the vehicle would be unable to move (ever again), the occupants would likely be trapped within, and this all assumes that nothing flammable or explosive touches off in the process.
Of course there's a chance you'll break it, but try stomping as hard as you can on a strain gauge (scale) and see what it measures. You'll notice that it is much higher than what you actually weigh.
And yes, scale is definitely off. A tank of equal mass should be at least knee height to a mech, and to be quite honest, every mech in the game should really be much heavier than listed... But its just a game, and when first put out back in the early 80's games usually weren't researched that hard before publication and weren't originally intended to have lasted as long as this one has. Back in the 80's roleplaying games like Battletech, Mechwarrior and many other titles were being rolled out at the rate of 100 a week to cash in on the craze and popularity of the genre of the time. They simply weren't thought thru all that much in the rush to push them out. Literally everything had its own RPG during that decade (Indiana Jones, Conan, Battletech, Teenage Mutant Ninja Turtles, Star Frontiers, Robotech, The Last Starfighter, every movie or book was being turned into a game during that decade - few survived).
