The historical cases support an institutional argument for distinct military services and career paths. A senior land officer cannot automatically command a fleet, just as a career sea officer cannot automatically command a division ashore, because both roles depend on years of specialized experience. The comparison with preventive maintenance explains the cost: removing that investment appears cheaper until failures create much larger operational and financial losses. Command appointments must account for the professional knowledge an officer has actually built.
