Shock Troopers upgraded with Blink Packs
Provide a short-ranged teleportation ability to Shock Troopers
Blink packs are small antenna like devices that allow some high-end Scrin units to teleport short distances across the battlefield. Only a few of these units have been witnessed using this advance technology: Shock Troopers, Masterminds, Prodigies, and Mastermind/Prodigy-upgraded Eradicator Hexapods.
It is also worthy to note that Traveler-59 Shock Troopers and Prodigies seem to come "pre-equipped" with those devices, while regular Scrin forces and Reaper-17 must research it at a Technology Assembler (Stasis Chamber in Kane's Wrath).
