Another Snippet of a deleted scene has been inserted…look at 20 second in.
Appears to be some sort of Skirmish on Jedha probably explaining the crashed x-wing fighters and alike. It’s a shot of Saw’s Rebels running into some sort of battle.
Man talk about Tease us…
EDIT:
Actually looking again the cliff is crumbling in the Back Ground don’t remember that shot though in the film…
