I have been told that the black stormtroopers in Rogue One: A Star Wars Story will belong to an elite unit called Death Squad. It takes me back to the Kenner line of Star Wars action figures that had a “Death Squad Commander” before it was renamed “Star Destroyer Commander.” I’m not sure if the name is in tribute or merely a badass-sounding coincidence.
In trooper news, I’ve heard another trooper mentioned called the “Pinnacle Trooper.” At this time I have no point of reference for the design. I do wonder/speculate if it will be the the long-faced black stormtrooper? In other points of clarification, the stormtrooper with the green lights by the microphone areas of the mask are the classic Death Troopers and not the long-faced one we saw in the Donnie Yen-released photo of the masks.
If this information pans out to pertain to screen-used terms, we will have a Scarab Trooper, a Pinnacle Trooper, and a Death Squad consisting of black stormtroopers in Rogue One: A Star Wars Story. The Empire has never sounded more menacing.
