Dumb newbie question, but I've noticed in some lists of unit stats that there are two types of bodyguard for Roman generals - early ones with armour 3 like Equites and later (Praetorian?) ones with armour 11 like Praetorians. Can anyone tell me what determines which ones you get? I would guess any Generals that come of age after the Marian reforms get the Praetorian ones - is that right?

I don't suppose there is any possibility of upgrading the early ones to later ones? (There wasn't in MTW, IIRC).

Thanks for any advice!
