So, no tanks for comparison? Guess some would be smaller. > At over five meters, the Mercedes GL X166 is one of the largest SUVs. According to the German Transport Club, it is even bigger than a tank. (Actually, "than a Panzer", and discussing what is a tank and what is not is the same w/ the Panzerwaffe in germany, e.g. a Marder, not a Leopard, here)
That’s large for a tankette (https://en.wikipedia.org/wiki/Tankette. https://en.wikipedia.org/wiki/Carden_Loyd_tankette shows how small these could be) but small for a tank.
