In ancient Rome, the leader or commander of a decuria (a unit of ten soldiers or citizens).
From Latin 'decurio', derived from 'decuria' (group of ten). The '-ion' suffix indicates a person holding a position.
A decurion held a middle-management position—leading just ten soldiers might not sound impressive, but multiply that across hundreds of decurions and you have the backbone of Roman military might!
Decurion (Roman military/administrative rank) uses masculine -ion suffix; while rank itself was male-exclusive in antiquity, modern usage should not assume gender of person holding comparable roles.
Use with person's actual gender, or use gender-neutral 'decurion' without gendered article/pronoun.
