Here is the smallest manned tank ever made
The Badger is officially the smallest passenger tank on Earth, according to the Guinness Book of World Records. It's a one-man, all-terrain vehicle designed to breach buildings and other fortified positions. It's powerful enough to break down doors yet small enough to fit in a lift.
Make no mistake, this tank is not a novelty. Howe & Howe Technologies, the makers of this little beast, have experience making vehicles for the military. Howe & Howe specializes in the fabrication and design of armored and military-grade vehicles. The Badger, however, is currently being used by SWAT teams.
