I would call the Roman Army an imperial force, but much army were auxilliari, locally raised troops with idiosyncratic arms. Slingers from Rhodes, archers from Libya, light cavalry from Numidia and heavy cavalry from Sarmatia.
Of course, the legions and the Navy (including the Marines) had weapons of similar pattern, made in state factories. There were still local differences though. For example, mail armor was standard almost everywhere, but the iconic segmented armor was only in Europe and only for a century or so
