From the reading I have done, it sems that there was a big differnce between how a Roman soldier fought and how a Gladiator fought.
Gladiators were tuaght a style that was more open and entertaining and it's surprisseing to read how many Galdiator contest did not end in death.
A Roman soldier was taught to kill quickly.
Baseed on reading others, the show Rome gave about the best idea on how Roman soldiers fought in battle and in other enviroments.
Its not really all that surprising that most gladiatorial combats did not result in death when you consider a few factors. These men were under some form of indentured service (contractural or enforced) and couldn't just leave if they wanted to. Add to this the fact that the
lanistas (the guys who owned the gladiatorial schools) had to be compensated if a fighter was killed to cover the expense of training him. In fact, Augustus banned death matches because the costs of compensation were becoming too heavy.
The training of gladiators was very interesting. It was very reminiscent of some of the martial arts schools that exist today. There were teachers, called "
doctores", there were ranks, training devices (the "palus", a pole stuck in the ground about 2m tall, and dummy weapons), and training used a choreographed system of numbered movements.
Gladiators don't seem to have been trained to fight unarmed. They were trained as weapon specialists and used a specific weapon and fighting style in the arena.
Gladiators even did product endorsements. They were truly the professional sports celebrities of their day.
An interesting little fact about the emperor Commodus (the one in the film Gladiator). He was particularly fond of gladiatorial combat and took to the arena himself. He was left-handed and fought with a
gladius (there are reliefs of him in gladiator kit).
There wer an estimated 100+ gladiatorial schools throughout the empire. There were four in Rome itself.
