Tank

Tanks are large, segmented and heavily armed land vehicles utilized by Bowser and his armies in Super Mario Bros. 3 and the television show. Tanks are equipted with various artillery, such as cannons, jet engines and Bob-omb launchers and also Rocky Wrench pilots. In addition, some tanks were just mostly square in shape, presumably being the command tank due to the pipe on top. Their texture is the same as that of the Airships in Super Mario Bros. 3.

In Super Mario Bros. 3, only two Tank companies, which guard Dark Land, appear, the first one being found in the kingdom's first area and the other in the last portion of it; the first company (composed of either 13 tanks (NES/SNES version) or 10 tanks (GBA version), including one with a flamethrower, one super-tank, and one with larger artillery) being commanded by Boomerang Bros. and the second company being commanded by Boom Boom. The latter company was composed of two regular tanks and three super-tanks, the latter of which were named because they were far larger than normal. In addition, Airships were seen aiding the latter company, possibly implying that airships and tanks sometimes work together in the same company.

Tanks also appear in The Adventures of Super Mario Bros. 3 episode "Princess Toadstool for President"; here, several Tanks and Rocky Wrenches appear to attack Mario and Luigi when they enter Dark Land.

Trivia
In the manual for Super Mario Bros. 3, Lemmy's character quote mentioned that he heard that his father, Bowser, was creating a new weapon. Whether the weapon were the Tanks, the small Airships, or the Battleships wasn't specified.
