The Legendary Sovereign epic destiny involves ruling a nation.
This might depend on which table you were playing at.
For instance, 1st level PCs are relatively unlikely to recruit squads of soldiers to support them. Paragon or Epic tier PCs are far more likely to do this. Mechanically, a squad of soldiers might be a bonus on a check in a skill challenge (out of combat) or a particular sort of ability or resource to deploy (in combat) - for instance, when one of the PCs in my game had a squad of drow hand crossbowmen in their service, in mechanical terms that was a minor action AoE attack (as they gave the command to shoot).
