That's a good point, the matter of timing different fleets from different sources to arrive at the same time is definitely an operational challenge.

I think it's a bit difficult to describe a game as purely strategic/operational/tactical.

Games can contain strategic/operational/tactical elements or choices, and I would say that a game where the vast majority of choices are operational can be called an "operations game".

When I played Konquest/Galcon, I felt that the biggest challenge was figuring the correct timing and order of expansion, which to me feels like strategy. It's very possible that AIs would disagree with me.
