There are several Qiraji Battletanks in the game, obtained in various ways:
Black Qiraji Battletank
This is a black silithid mount which can be used anywhere, but was only obtainable if you were the person to bang the gong to open the Ruins of Ahn'qiraj instance on your server. That person also gained the Scarab Lord title. Neither the title nor the mount is available anymore.
Red, Green, Blue and Yellow Battletanks
These are mounts in various colors, which drop from trash mobs in Ruins of Ahn'Qiraj (AQ40). They can only be used inside this instance and are pretty common (except the red one, which has its own achievement to obtain).
Scepter of Azj'Aqir
This is an item which you can dig up using the new Archaeology profession, and teaches you how to summon the Ultramarine Qiraji Battletank. It's a very rare item to obtain, and requires finding a lot of Tol'vir artifacts at a skill of 425+ in Archaeology.
There is no Battle Tank mount in World of Warcraft.
The biggest tank in the world would probably be the US M1A2 Abrams main battle tank.
The most advanced tank in the world is the M1 Abrams Battle tank that is for the U.S.
