When a card references the number of Hoth objectives with the new force packs, does that count the number of objectives with the printed trait "Hoth" or does it include all objectives that are from the Hoth force packs?
These effects are only counting the objectives that are in play that have the Hoth trait.
So if you have three objectives in play with the Hoth trait listed, keep in mind that the Echo Base enhancement has text that states:
You are considered to control 1 additional Hoth objective.
With that enhancement on the board, that means that you will be considered as having four Hoth objectives, which would give any Wilderness Fighters units on the board four Unit damage icons in addition to their existing edge dependent Blast damage icons.
That's a pretty sweet combo, IMHO!
