Extra MIC buildings and cheap units?

[chaosklima]

Hi
I'm new to the EB mod and have only played a couple factions thus far. I have a couple questions and couldn't find them in the FAQs.

1. What are the secondary military buildings for (I think they say foreign troops and levies, or something similar)? Every time I build them, they never produce any troops. Do these buildings do anything? If so, what? Why are they available to build if they don't produce troops?

2. Are there any inexpensive levy-style troops for hire, such as Vanilla's peasants? For EB, I raise units of the cheapest troops available to keep in my cities (archers or slingers, usually), but even these units get expensive when you have 25+ cities stocked with a few units of archers each. Am I missing something? Do other players have to do this as well?

Thanks,

B
