How to unlock the Veterans' Day achievement in Grand Ages: Medieval - Definitive Guide
While fighting and exploring, your troops get experience and once one hits 100 then the trophy will pop. This will very likely happen during the campaign but if not, then you'll get it whilst going for the Go to Hell trophy.
