In Shingeki no Kyojin, the Three-Dimensional Maneuver Gear is a set of gear developed by humans that allows great mobility when facing the titans. 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:
Wire and grappling hooks
Gas powered propelling system
"Replaceable Hardened Steel" swords (超硬質ブレード) and sheaths
