Final answer:
Guardians are Plato's ruling class trained from a young age and auxiliaries served as supporting forces to Roman legions, each with their social and professional separations. The concept of separation also applies to the personal lives of service members who have to deal with the challenges of being away from family during military deployments.
Step-by-step explanation:
The question relates to the historical concept of guardians and auxiliaries within different societal and military structures. As Plato described in his works, notably 'The Republic', the guardians are meant to be the ruling class, trained from a young age to develop virtues and are ultimately the philosopher-kings of the city. Their life was communal, with no private ownership of property or exclusive parental ties, to prevent conflicts of interest and ensure devotion to common good. Meanwhile, auxiliaries historically served as a supporting military force to the Roman legions, with service leading to privileges like citizenship.
The Roman auxiliaries, consisting of both cavalry and infantry divisions, played diverse roles ranging from scouting to combat, well integrated with the legions for efficient military operations. The separation mentioned could refer to the social and professional distinctions between different classes of soldiers, or between military personnel and civilians, especially with the noted promise of citizenship ameliorating such divides.
References to the guardians' and auxiliaries' separation can also be seen in other societal contexts, where the structure of military families shows how service members and their families deal with separation during deployments and the associated challenges of responsibility-sharing and emotional stress that comes with long absences.
