The first category, returning to ASL, features scenarios found by Daniel Zucker that meet the criteria of being European Theatre, Infantry Only and do not have DASL or HASL boards.
There is no guarantee any of these scenarios are balanced or fun, just that some people think they serve as good introductions to certain parts of the rules.
I think we might be able to help you out. So you're either new to ASL or are returning after a break and want some advice on what are good learning or re-learning scenarios.
