In Shingeki No Kyojin, the Three-Dimensional Maneuver Gear is a set of gear developed by humans that allows great mobility when facing the Titan (Shingeki No Kyojin)s.
The gear itself takes the form of a body Harness that encompasses much of the body below the neck. Though using it will allow a skilled user great mobility, it carries a large risk of overtaxing the user's muscles, thus using it demands a special physical conditioning and sense of balance. Some tools involved in the apparatus include wires and Grappling Hooks, a gas powered propelling system, and "Replaceable Hardened Steel" Swords and Sheaths.
