Been working away at these guys for the last little while. They are Persian kardakes or Lydian hoplites and some armoured Persian archers. The figures are Hat 1/72, which are okay, but not quite up to Zvezda. The shields are topped with LBM transfers which are superb, although a little small for the shield size. They are based on 60mm frontages which can convert to just about any ruleset. I'm thinking Impetus but have been reading FoG too.
