World 8-Super Tank

 is the second tank level, and the tenth level overall, of Dark Land in Super Mario Bros. 3. It becomes accessible after the player clears and its own completion opens. It is automatically accessed when the player moves over its icon on the map.

Layout
Like with the first tank level, this level autoscrolls, though only the tanks move. If the player is standing on the ground, they will not move with the screen. This level has a small tank with a cannon in front leading a group of three longer tanks, armed with more cannons, Bob-omb launchers, and Rocky Wrenches. Additionally, small Airships lined with cannons attack from above. If the player can make it to the final tank and go down the Warp Pipe, the final fight with a flying Boom Boom will commence.
