Yet again no pictures (Actually, I'll sneak in a question here, how do you upload them anyway? ) but:

Kavakaza Sparabara - Caucasian Spearmen

Hai Nizagamartik - Armenian Spearmen

Kovkasi Lernain Netadzik - Caucasian Archers

Neither of these units have ever disappointed me in my Hayasdan campaigns (Early game that is) and I've been able to conquer the entire Caucasus-region (The city where Hayasdan and the nearby settlements, 5-8 something, not sure and dont have EB available for checking) with armies consisting only of Kavakaza Sparabara and Kovkasi Lernain Netadzik in my early games (And family members, wich.. Might be tad bit better in terms of quality.). The Kavakaza are really good considering their price, same goes for the Kovkasi, in my oppinion In all my Macedonian/Seleucid games I also make sure to hire some Caucasian archers, I just think they are plain awesome .
