Had anyone looked at the unit names for the Seraphim units and "translated" it? I've thought about it now and then, and I see patterns. I can't be the first person to think about it.
For example, Selen is scout, Yth- has something to do with missiles (Tac or strat), Ia- tends to be things that shoot at aircraft. -Ioz seems to be some form of "Denial" and is shared by Strat defence, T3AA, and torpedo bomber.
