Interesting. Anyway, Gaesatae is what I was thinking about instead of Teceitos.

The Silver Shield Pikemen from the game were not the Silver Shields of Macedon. I was reading about them, granted it was Wikipedia, and the original Silver Shields were Hypaspists, though there was a similarly-named unit of Pikemen in Seleucia, and the Silver Shield Legionaries are realistic as well. I just need to borrow my brother's book on the Hellenistic armies, I guess.
