The omni-directional mobility gear (立体機動装置 Rittai kidō sōchi?), is a set of equipment developed by humans that allows great mobility when facing the Titans in combat. The equipment allows the user to fight in a 3D space as opposed to a 2D one. The equipment itself takes the form of a body harness that encompasses much of the body below the neck.

Although the equipment can grant a skilled user tremendous mobility, it is a demanding art that requires strength, and skill, both of which must be honed through constant practice.

Some tools involved in the apparatus include:

  • Hand grips 
  • Piston-shot grapple-hooks
  • Gas-powered mechanism
  • Iron wire propeller with plug-in blades

Usage

3D Maneuver Gear

Soldiers using ODM gear

The simplest move possible with the ODM gear is simply aiming and firing the grapple hooks at an object and then activating the gas mechanism to reel oneself toward said object. They can then disconnect the hook and continue moving forward.

Usually however, soldiers must be able to move around in order to navigate in general. Therefore, they tend to use their momentum in order to swing around targets, not only in rectilinear patterns, but also slaloming between objects and Titans. The gas mechanism is so powerful that it can stop a person from falling without using the hooks.[1]

The ODM gear tends to be less efficient in open spaces because the user does not have too many spots where the hooks can be reeled. However the hooks are able to pierce Titan flesh and ODM gear can be as fast or even faster than a Titan.

More advanced techniques include changing directions while still being reeled in as demonstrated by Jean Kirschtein.[citation needed]

Mechanics

  • Body of the Device
  • Operating Device and Gas Cylinder
  • Fan Section

The Body of the Device - Steel wire is stored inside the body, installed in the lumbar area of the back. There are two axles, which revolve independently.[2]

Operating Device - The functioning part of the operating device is a black box, which the technical department manages and improves in secrecy.[2] The operating device has two triggers that launch the hooks, a lateral switch that aims the hooks and a brake. It also has a top piece where blades are put for combat. Thus the operating device also works as a sword's handle.

Body of the Compressed Gas Cylinder - Gas is compressed into the cylinder and injected.[2]

Blades - The blades are made from an ultrahard steel, which is both supple and strong, capable of rending Titan flesh. It can only be manufactured in the blast furnaces of factory cities.[3] Soldiers usually carry more blades in boxes built at the sides of their thighs.

Fan Section - Gas is blown directly into the fan to make it rotate. The pressure of the gas is regulated to manipulate the output.[4]

Training

  • Moving in the third dimension
  • Crucial Qualities

ODM gear training is a rigorous process that allows humans, which are limited to two-dimensional movements, to adapt to movement in the third dimension.[5]

Great physical strength, particularly in the legs, coupled with spatial recognition abilities, as well as the mental strength to not waver in the midst of a panic, are crucial qualities.[5]

One of the first things done after enlisting in training is the ODM gear aptitude evaluation. Those unable to remain upright are dismissed.

"Those incapable [of staying upright] aren't suited to even be used as decoys!"[6]

Three years of training are needed before officially becoming a soldier. Many run away or are driven out before graduating. The training is so intense that some people actually die during the process.[7]
