Thanks Procopius!
I just have some doubts (because I still have to read again all the books I have on the argument).
First, cataphract. I remember that in Komnemian Army they weren't the incredibly slow and heavy cavalry as in the past and they were restricted to the imperial Scholae while the bulk of the cavalry was made by the Pronoia nobles and clients.
Second, your list lacks of the cretean archers who replaced the Varangian Guard as imperial units till the fall of Constantinople.
Can you help me on these points?
