 As can be told from the huge Illerup Ådal excavation in Denmark, in which huge amounts of Roman and Roman inspired arms and equipment were found.Many of these were probably produced in Scandinavia, and many had Scandinavia "factory seals", after a Roman model.This not only tells us that the Germans did indeed use Roman arms, but it also tells us that they had the required knowledge and social organisation to support large armies, and produce standardised arms and equipment.
