The Herculiani Seniores (Herculians) were a Legion Palatinae (guard) unit in the Western Late Roman army, that were originally formed from the VI Legion, from Illyricum. Brigaded together with the Ioviani (Jovians), who I will have to paint later on, they were usually in the thick of the fighting! Please have a click.
I have just consulted my Late Roman expert mate, who says they might well have retained an eagle standard; I'll remedy this a little later on!
PS I mixed in a few Crusader minis, to add a little variety. Although slightly stockier, they fit in very well!
