I seem to have lots of distractions. I just finished rebasing my Byzantine foot and adding these mounted units so I’ll have enough Byzantines for SAGA. I now have a LOT of byzantines for SAGA. Conceptually this is a unit of Byzantine Kataphraktoi, front rank lancers, back rank archers. It’s probably a better equipped Thema unit. I would expect the Tagmatic Kataphraktoi perhaps to have half-armored horses at least for the front rank. Not so well equipped Thema units might not have archers.
In SAGA terms it is three points of hearthguard and would be organized as two units of 6, one unit with lances and one unit with bows.
