The Speed Unit is an armor enhancement that allows the user to move extremely fast. Simmons found this enhancement at the Freelancer Offsite Storage Facility and then installed it into Grif's armor. Without an AI, the user might experience an overload of speed. Grif stated that when using the enhancement people talk so slow, the lights hurt his eyes, he can smell clouds and it feels hot. He also became overly energetic and talked really fast. Simmons mentioned that the unit has a timer which may be a reference to the equipment timers in Halo: Reach. When the timer ran out, Grif collapsed in exhaustion. In the episode Spiral, Carolina uses the speed unit enhancement to catch an Insurrection soldier in order to obtain a briefcase.
