yep, they are normally used as a standard bearer so you'd assign a model that has flag instead of weapon I think (I don't know the modelling end) - you normally use fs_standard_bearer skeleton for them so they don't wave flag around like a weapon.

Its got nothing to do with captains or generals. Game assigns them in addition if unit is a bodyguard to a family member, or if the unit is the 'leader' of an army.
