The Levy Camp tooltip mentions medium infantry. I've played a lot of factions and other than Scotland I just see heavy infantry. When does medium infantry show? Is Levy Camp worth using?
Thanks.

In my game as Aragon, I have what i believe is medium infantry. It's not called medium however, just infantry.

Haven't used the levy camp yet.

What do you use to remove hastily levied then?

I've been using spearmen on the heavy infantry.
