Leading rating and able rating provide standardized grades across mechanical and other naval specialties. The generic title separates a person's position in the hierarchy from the technical work performed within it. Japan's shared rank structure requires additional service wording to distinguish naval personnel from their army counterparts. In many other armed forces, naval titles differ enough from army or air-force titles for the rank itself to indicate the service, although this is not universal.
