Don't remember if this has been addressed already and bla bla bla.
Opening crawl reads:
"Evading the dreaded Imperial Starfleet, a group of freedom fighters led by Luke Skywalker has established a new secret base on the remote ice world of Hoth."
But we never see him lead now do we? Sure, he's commanding Rogue Group during the Battle of Hoth - but that's on a mere tactical level.
Furthermore, while the Rebels regroup, he leaves for Dagobah on a strict personal errand for who knows how long. This is surely not the actions of someone who is part of strategic command.
Now, the one who's actually operating within the Rebel command center making strategic decisions (along with General Rieekan) is in fact Leia Organa. She's also the one giving the pre-battle briefing as well as the last post-battle orders. And contrary to Luke, her being separated from the Rebels regroup is not by personal choice.
Thus, the crawl should read:
"Evading the dreaded Imperial Starfleet, a group of freedom fighters led by Leia Organa has established a new secret base on the remote ice world of Hoth."
BUT, since the following passage reads: "The evil lord Darth Vader, obsessed with finding young Skywalker", we have to establish Luke's name somewhere in the crawl:
"Although the Death Star has been destroyed by Luke Skywalker, Imperial troops have driven" etc etc, and Bob's your uncle.
Just a thought and bla bla bla ;-)
