The Old Stratia used to be a hoplite spartan clan. Not really anymore, as we're based around pragmatism now (being a Remnant and all).
ATS used to be a hoplite clan. They've gone over to archery and horse archery. Or something. And throwers. Or something.
If you're looking to make a hoplite/spartan clan, you need dedicated individuals. The tactics involved are relatively complex. I know some ATS do well with it. I know a bunch of my boys do well with hoplite tactics as well. But it takes practice, and shield and spear really doesn't work well without a buddy.
