So I rewatched the first half of episode 1, mainly looking for Kugel's Machine Caliber to compare with events in episode 10. During the pre-battle speech, we were shown Avalon in pristine condition, and destroyed and overrun by the Hideaze. Which leads me to a few observations and possibilities. (Not sure if these were discussed earlier).
- Avalon is already destroyed, and the GA soldiers were not told about it to keep morale up. (possible, but I think it's unlikely)
- What was shown was a prediction of what will happen, shown to the troops to increase their resolve.
- What was shown wasn't Avalon at all, but another colony that has actually been destroyed.
