Even though the Imperial reforms are a long, long, very long way off I do feel a bit saddened that Cohors Imperatoria still uses lorica hamata. I assume that the the Imperial reforms take place sometime during what would be the reign of Augustus; and since pieces of loricae segmentatae have been found in Germany at the supposed site of the Teutoberg battle that could theoretically place the development and use of the armor sometime before 9 CE. I know that after a while its use practically ceased due to the the expense of it and the upkeep required, but that would happen well after then end of EB.
So, why no lorica segmentata? Was it that uncommon?
