A unit roster for that era will be basically the Comnenean one with just few changes.
Things that we must always remember.
Romans had to few archers.
They had few horsearchers but they still had some of their own.
After 1080 they used more and more mercenaries.
Units like :
Mourtatoi (infantry archers)
Gasmouloi (latin crossbow militia)
Varangian guard
Alamanoi
Vardariotae (magyar horse archers)
Scithicon (steppe horsearchers)
Latinikon
were all mercenaries in the emperor's service.
If the team would like to make some changes even to those units it could:
Alamanoi
Scithicon
Gasmuli
Latinikon
To be continued soon.
