This is a hard question,

I would be a Misthophoroi Toxotai Kretikoi. The reasons?

- I'm the most wanted merceneray in the whole Mediterranean
- I can punish medium infantry with my short sword if they dare to come closer
- My employers usually keep me protected... that means if the things turn bad, I have a good chance to survive the battle
- I'm one of the best archer in the world
- My payment is quite high compared to the others
- I have a good chance to see new "worlds" as my employers buy my services for long terms usually
