Mammoth is a fortress on the treads. It has the most health of all tanks in Tanki Online. It is considered to be one of the best tanks, for both campers and chargers. But it is very very slow. Mammoth on drugs, however, is almost impossible to kill.

Best to use with Inferno paint so Freeze won't slow you down that much.
