Pegasos was one of the most common symbols on the obverse of coins from Greek cities. My coinage books are in storage (I'm in temporary quarters currently), but it's pretty amazing when you flip through and see city after city that has it on their coins. Not that there weren't other options (I think the head of Athena was high on the list, and of zeus, as well as a couple of other things), but it was really common and it was very recognizable, and once parmenio did our logo for us, we absolutely loved it and were more than happy to keep it.

Like I said, there will be another KH infantry unit from what I've read - though I honestly don't know much about it other than it's a good one. I'm KH faction coordinator, but when it comes to units Urnamma pretty much handles them. I'm more of a history/culture/text coordinator for greek factions and he handles all their unit decisions (well, he heads those unit decision discussions - he's not the unit tyrant as far as I know ).
