double blah, but I'll leave the stuff on cataphracts/Clibinarnii
The most impressive looking cavalry in Late Imperial forces were doubtless the Equites Catafractarii and Clibanarii, fully armoured men wielding 12 ft (3.6 m) lances and mounted on metal-barded horses. They had evolved following Romes conflicts with Armenia, Parthia, and Persia, and became an important force, especially in the East. These cavalry did not charge into battle but trotted forwards pushing enemies aside as much by fear as martial prowess. The kontos or lance was a heavy-bladed cutting weapon that was wielded with both hands, slicing and stabbing opponents in an almost fencing style of combat. The precise difference between catafractarii and clibanarii are still debated at length, but the available information suggests that clibanarii came from the East and catafractarii from the West although, confusingly, both terms are used by some sources to describe the same troops!. Standard-bearers carried the draco standard and would be equipped as other troopers, It is imoprtant to add that they still utilized a shield strappd to the forearm, so that they could benifit from its protection while still being able to manipulate the lance
