The Braha'tok gunships had already been identified in the trailers. As for the twin-pod TIEs, indeed somebody indicated they could be TIE/br instead of TIE/sa - which hadn't crossed my mind but would make perfect sense in that scene...But am I the only one who noticed the Bra'Tohk Corvettes and Tie Boarding Craft in Rogue One?
I'll try again now that someone's talk about TIEs. During the battle of Scarif, the Death Troopers take land from some kind of TIE transport. We can see this ships escorted by two TIE striker. The ships is like a striker but bigger and have some other differences. What ship is it? (It already exist or they created it for this film? Anyone knows?)
