7:40 - Colonel Gascon (about the prospect of WAC-47's getting a promotion): "Over my dead body." Han Solo uses this same expression in A New Hope [50:42].
18:16 - Colonel Gascon (to WAC-47): "This is our only hope. We've got to stop following my training or your programming and follow the birds' instincts." Leia uses the phrase "only hope" twice in A New Hope ("Help me, Obi-Wan Kenobi; you're my only hope" [35:35] and "You must use the information in this R2 unit to help plan the attack; it's our only hope" [1:38:49]); C-3PO uses it once in The Empire Strikes Back ("Your highness, we must take this last transport; it's our only hope" [31:49]); Obi-Wan uses it once, referring to Luke, in Return of the Jedi ("You were our only hope" [47:24]); and Luke uses it once, referring to Leia, in Return of the Jedi ("If I don't make it back, you're the only hope for the Alliance" [1:19:39]). Sio Bibble also uses it in The Phantom Menace: "Our only hope is for the senate to side with us" [23:48].
20:08 - Colonel Gascon: "I don't believe it; those mechs beat us here." The context is quite different, but Luke also says, "I don't, I don't believe it" in The Empire Strikes Back, after Yoda uses the Force to get his X-wing out of the swamp [1:13:10].
