What about there armor? What did they wear?

Contrary to popular belief, the Roman Army wasn’t a (literally) uniform fighting force with large shields (Scutum) and segmented armor (lorica segmentata). Often older yet still usable kit would be matched with newer designs, creating an effective but more varied look from soldier to soldier. Furthermore, as there was no central armory catering to the legion’s needs (instead, regional workshops carried out contracted works), equipment from certain regions would carry different design and pattern signatures. A soldier in Brittania would look rather different to one in warmer regions of the empire. Also, legionaries would often customize their own armor, setting it apart from his fellow brothers-at-arms.

There was a medal system within the legions as well, known as Phalera. Large metal discs attached to belts worn across the chest were used to delineate certain actions the wearer had untaken in battle (such as breaching a wall or capturing a standard).
