Are you ready to do battle for the glory of Caesar? Have you bought your own armor yet--an apron and strong marching sandals? Will you become a centurion or a legionary? Are you ready for a posting to Western Eurasia or Britannia or North Africa? Are you ready to train from 6 a.m. to midnight? Are you fit to march long distances? Can you swim, run, jump, fence and throw javelin? Then prepare to swear your oath of loyalty to the Commander and Emperor.
