The hall will be a really easily defensible position; that's a good idea. We should have squads of people working together, too. After all, we don't know how strong these Beemon are and we'll have a lot easier time of fighting them if we do it as a team.

The most important thing to remember is that they can fly, though. That means most defensive fortifications will be useless. If we want to stop them from destroying the town, we'll have to get their attention somehow before they decide to hit a building. Maybe like, one person from a squad draws in the bees by directing their partners to fire at a bees with an accurately ranged attack to draw them in so that the others can knock it out by attacking in unison?

[Ed pauses and thinks about it before nodding quickly.] That'd be the optimal strategy for dealing with things using Rookie digimon, but it won't hold up once the Beemon's numbers become too high, and you've seen the videos. By then, we're going to be relying on digivolution, with the teams working together using Champion level digimon. In the worst case scenario we can all fall back to the meeting hall and stop them there, but that'd be really bad since it'd also mean most of the town getting destroyed.

Those are my thoughts, as far as a strategy goes. I'm not sure how it'd piece in with yours, but... it's all I've got?
