I know that the Notitia was put together at later times however it refers to many of the Cohort strengths of the Hadrian's Wall forts being commanded by Tribunes and with cavalry by Prefects, then as far as smaller units we should from fort layouts consider that the Maniple looks more the together unit than a century for barrack blocks at most forts tend to be grouped in this fashion, Chesters fort on Hadrians Wall being a fine example with close facing blocks.
