Well, can anyone explain why there are Evocatae in Marian period, but there aren't Evocatae in Augustan period?
I think I know why, but just want to be sure... (IMHO 'cause the Augustan legions were proffessionalunits with fixed, long-term service of 16 up to 25 years, so the "ordinary" Augustan legionaries could be as trained and experienced as Evocati were... and Evocati apperaed during grim years of civil wars, when they provied quite substantial part of legions formed by the pretendents struggling for absolute powre over Roman Republic... - like Octavianus forming legions from Caesar's legionaries...
