Optio equipment

[jbd_29349]

I was just promoted to the rank of Optio Centuriae and was wondering what kind of equipment an optio would wear and carry.

I know that some of the defining features of an optio was the front-to-back crest, and feathers on either side. He also carried a hastile to keep the men in line during battle.

I am asking would he wear a segmentata, squamata, hamata, would he wear greaves/greave, would his subarmalis have ptergis. Would he have torc/torcs or even armillae? Is their any historical evidence out there?

Oh, first century early second century AD.
