Hhhmmmm, definatly Sacred Band Cavalry during the second punic war :D
There are either 2 things which can happen, either your send of with Hannibal, one of the few generals you can be sure off not to trow your life away, and he loved his cavalry, so chances are, I live :D The other possibility is that you aren't sent along with Hannibal and you have to remain at the temple and prouncing around a bit on your beautiful horse and armor and attracting all the beautiful young girls...

oh, and don't forget about that you probally join in the fun of holy prostitution with the temple virgins too :D

And did i mention you are very rich too??
Definatly the place I'd like to make my career :D

One place I definatly wouldn't want to be is any roman legion during the second punic war :P That just doesn't sound like a good place to make a career for yourself :P
