[@Alfhedil] If possible, I'd like a little more clarification as to who someone would be transferred from the Third to the Second Division, such as additional training, if an appropriate sponsor is required etc

It's dependent on region, though most of them go by a merit system. The more merits one gains through combat actions or tours of duty, the greater the chances of being acquired by a Second Division recruiter. Actual sponsorships aren't as common throughout the Confederacy except in the more aristocratic societies, since it is meant to be a more special forces/alpha strike division. In most cases, all one needs is a letter of commendation from a superior within either higher division, though First Division letters are almost always followed through immediately.
