Yeah, I just looked at the clip and I’m pretty sure this is Burnell Tucker in both instances. But the “It’s metal!” guy ISN’T the same Rebel as “Enemy Fighters” guy?

FYI his “second” character in Empire is at the end of that clip, on the right of Rieekan. But yeah for sure, according to Wookiepedia I think the characters names come from the novelizations so probably at the time whoever came up with the names just had no idea all three were the same actor.
