NASA's Crawler-Transporter weighs only 2,721 tonnes (just shy of 3,000 tons) and is the second-largest vehicle in the world. The largest is the Krupp Bagger 288, which, at 13,500 tons, has a top speed, depending on the terrain, of between 0.1 and 0.6 km/h.

Also, the amount of resources just to run it, let alone build it, would be phenominal. The Crawler-Transporter does 127 gallons per mile. When it comes to construction, the two most comparable RL vehicles are both unarmed and unarmored, and still the two Crawler-Transporters cost $14 million when they were built in the '60s and it's far less reasonable to expect a 50+ year service life from a war machine; the Bagger 288 cost $100 million when it was built back in the '70s. It's also worth noting that the Bagger 288 can't even move under its own power (it needs an externally-provided electric power source), which technically makes the Crawler-Transporter the largest self-powered land vehicle in the world.
