training units

[Trithemius]

If the Baktrians are anything to go by, in 0.7.4 there are some rather strange recruitment issues. I suspect that things should be ironed out a bit for 0.8 (there have been suggestions that this is being worked on), but you might want to check out the 0.7.2 Current Recruitment xls file for some indication of where to find the troops you want.

Iberian Assault Infantry should be available in Lilybeo, Arse, Mastia, Baikor, Gader with the combination of a Type II (EDIT: or type III, which I just checked in Arse) government building and a Army/Royal Barracks (level 4 and 5). I am not entirely sure, as I have mainly type I governments in those cities in my current Kart-hadast campaign, but thats what it says in the barracks descr.

You can retrain the libyan and liby-phoenician infantry of your Alexandria army in the closest town to the west of Alexandria (between Kyrene and Alexandria). For your more elite units you'll have to go back further home.

You can edit certain files to make them available in Alexandria, I dont know how thats done, part of the fun of EB for me is that units arent available too far away from home.
