Re: Star Wars Anthology: Rogue One
Axlotl, thanks for clarifying that for me.

I had a hazy understanding of it at best.
Has the wookiepedia canon been mentioned yet? It claims that red 5 is the call sign for the fifth member of red squadron.
Luke was red 5 in the battle of yavib but another guy was red 5 in the battle of endor
Try not to say "Wookieepedia" and "canon" in the same sentence.

Remember it's user-edited, and still has a lot of no-longer-relevant EU content padding things out. The only Red Group pilots given callsigns in dialog in ROTJ were Leader, Two, and Three. The script isn't much help (Gray Leader and Green Leader are both called out as being in X-Wing cockpits when they call in, Red Two and Red Three in the script have lines delivered by A-Wing pilots, and -- what's more -- the actor we see as Gray Leader earlier is addressed as Red Two by Wedge later... It's a mess). All the rest are conjecture from various EU sources.
It would stand to reason that as Luke moved up in the ranks of the Rebel Alliance so would his standing in Red Squadron and considering that Red squadron was all but wiped out at Yavin he would naturally no longer be Red 5 which, I always assumed, was the call sign for the junior most member of the squadron.
Except that, during the call-in sequence, we heard from all the way up to Red Eleven. We saw Red Leader, Wedge, Biggs, and John D in the first four ships, and Porkins and unnamed Reds Ten and Twelve (plus hearing from Reds Nine and Eleven over the radio) on up the other side of Luke. From the novel and radio drama, I mentally filled in that -- with Biggs' endorsement -- his simulator scores were sufficient to let him fill the vacancy in Red Squadron.
Wedge, being the senior most survivor of Red Squadron gets promoted to Red 1 or Red Leader and Luke, being the only other survivor, would be promoted to Red 2, presumably Wedge's XO. Of course, this logic ignores the fact that on Hoth Luke is Rogue Leader with Wedge, presumably, underneath him. So if Wedge was indeed promoted to Red Leader it would be very unusual for him to be part of Rogue Group and under the command of his Red Squadron subordinate, Luke.
Pretty much my thinking, too. I was only six when ESB came out, but from reading and re-reading the storybook and watching the laserdisc and looking at the still photos that were around, I noticed even then that Luke's X-WIng all through ESB still had the five stripes on the wings. And then again in ROTJ, while Wedge was now Red Leader. So by 1984 I had come to the conclusion that Wedge had gotten promoted, as seniormost, and Luke stayed at Red Five as the Squadron was rebuilt, and they just didn't have a Red Five at Endor (despite what EU sources from later on say). And that if Wedge was bumped down a number to Rogue
Three, while Luke was Rogue Leader, then it had to be some other formation than the fighter squadron we'd seen in the previous film.
