That is a great looking army. If I were to do a Spartacus army I would want it to look just like that but that does lead me to a question though.
If you've ever worn a gladiator helmet (the uber cool looking ones) you'll see they were designed to deliberately restrict vision and were in most cases designed for show - they could stop a blow alright but they were extravagantly designed.
A Roman soldier or any other soldier for that matter would never wear such a helmet - not practical for fighting. So, is it likely that a gladiator would wear a gladiator helmet such as the Murmillo is forced to wear in the ring?
I know we all want our gladiators to look fabulous - I do. But ....
