3D Maneuver Gear

3D Maneuver Gear  (or 3DMG for short) is a complex weapons system devised to give humanity an edge in their war against the Titans. Mikasa is particularly skilled in using it.

Overview
Perhaps the most obvious advantage the Titans held over humans is that they're freaking huge. Brilliant engineers and social outcasts decided that the best way to circumvent this advantage would be to create a device that lets them get to eye level with Titans, presumably so that they can see the rude gestures the humans make at them before they are eaten.

Just kidding.

The main function of the 3DMG is to allow humans to manuever in three dimensions, allowing them to attack the only known weak point of a Titan, the back of its neck.

Features
The 3DMG accomplishes this goal through a two-fold system of mobility enhancement and weapon storage.
 * Anchors- The primary mobility-enhancing device of the 3DMG is its twin anchors. The gas-powered anchors are connected to long cables that extend to lengths greater than twenty-five meters. The cables have a great deal of tensile strength, in order to support the weight of a free-falling soldier. These anchors are fired and retracted through triggers located in the Sword Hilts.
 * Gas Fan- In order to increase the speed at which the operator can travel, the 3DMG also features a compact, high-revving, pressure-driven turbine fan mounted on the back of the harness. The fan is fed through the same reserves of gas as the anchors, and so it must be used sparingly. The fan is also activated through triggers located in the Sword Hilts.
 * Sword Hilts- The main control interface of the 3DMG, the Sword Hilts are... sword hilts with a bunch of controls on them. They are connected to the harness by a cable-transfer system.
 * Paring Blades- The defining visual trait of the 3DMG are the two large boxes mounted on the thighs of the user. These boxes contain the Paring Blades, dedicated anti-Titan weapons. These are thin, rigid, segmented, razor-like swords that connect to the Sword Hilts via a quick-release mechanism.  The Paring Blades are made of ultra-hard steel and are designed to tolerate a great deal of stress from the blade edge, but are otherwise fairly brittle. To circumvent this wear, the boxes contain many, many extra Paring Blades which the user can switch to at any time if the current blades get dull or shatter.
 * Harness-  All of this is connected to a system of belts and straps that ensure the 3DMG is securely attatched to its user, and that helps distribute the weight of the bulky weapons evenly across their body.
