I imagine if they did the "unlimited troops" it'd be done in a star craft manner, you can't have a ton of them out fighting but you can produce more fighters over time after gaining more resources and losing people. Only a limited amount on screen (or on a sector) at a time. When one squadron dies you can ship in (manifest) a new one, after gaining enough resources.
