I hope so too.
I think we’re both referring to, “And General, unless that shield is destroyed…nobody can save us.”
Maybe another off screen rebel could be calling for 3PO, needing his help. Or some droid beeps. It could just be a subtle background voice/sound, but something like that could provide some logic to his action.
Ask and ye shall receive.
It’s funny, but also kinda brings the scene together.
