Sangheili Omni-Directional Movement Equipment

Sangheili Omni-Directional Movement Equipment, commonly referred to as Sangheili Power Grapple Gear and abbreviated as SODME is a piece of equipment used by the Sangheili. It allows for swift, agile movement within the three-dimensional plane, and allows for very quick maneuvering, which cannot be detected by normal heatseeking weaponry.

Background
The SODME was initially developed by Sangheili technicians working on an alternative mode of transport for Sangheili rangers. Its design is based off of ancient schematics found within a a Forerunner data archive, which depicted an unknown species utilizing similar a similar device to combat exceeding large enemies. This device was at first rejected in favor of the normal Jetpack, however it did see some use after the Great Schism, in which Sangheili strike teams could use them for combating large scale vehicles such as Scarabs or Liches. Post-war, it became common equipment for reconnaissance teams operating in areas with very tall structures, i.e. Mega cities.

Mechanics
The SODME operates using twin energy grapples located on the hips. They are, by default, positioned forward facing, though the user can change their direction through a pair of handheld controls. These double as the hilts for a pair of single bladed energy swords. These blades are akin more towards to human bladed weapon, and make up fir their lack of size in speed and energy consumption. The controls are also linked to a thruster pack located on the user's back. The thruster is used mainly to boost speed, but can to a degree allow for short flights.
