I use these 'Ancient German' cavalry for the later period 300-450 AD. They are very suitable as Goth,Ostrogoth or similar. Mixing the foot figures with the mounted is only an aesthetic although some sources cite it as a way of operating. I have plans to do units of these figures mixed with semi armoured types and equip them with long lances but no shields. These I would field as Gepids to compliment the Huns or other Dark Age hordes.
