OK. Then in that case the Orc Legionaries are different versions of the same four models, painted differently some with shields and some without, some with spears and some with swords - simple conversions.
The Halflings are the same - just different versions of the base Boche.
Cut away the spears or swords and you have most of these. Add shields ad you have a whole posse of variation.
There was plans for some more archers, but I'm not sure we will ever see them.
I hope that this helps.
