According to the Field of Glory Mid-Republican Roman army list you have various options to take units other ancient tribes and peoples. So after some consideration I opted for a battle group of Gauls. I did this for two reasons firstly I thought they'd be fun to paint and secondly they can be impact medium foot and hide in the bushes until they charge out an die heroically on the enemy's spear tips.
Hopefully this gives me enough time to do something clever with my legions and turn the battle in my favour. So far they have been very helpful in cancelling out the threat of my opponents medium troops. I guess I am beginning to think about this rules a bit more strategically and am starting to understand how to use different troop types for different roles, rather than simply marching forward and dying.
I really enjoyed painting the Xyston figures, so much so that I am considering acquiring a few sets of Gaesati "tout nu" guys to give me an extra set of optional troops. It will also give me a touch of practice painting some more Gallic shield designs.
