As a matter of fact, the ambiguity that exists when referring to any and all military personnel is merely semantic.

Marines and Navy corpsmen could be considered sailors, and the soldiers who operate armored vehicles for the Army and Marine Corps could all be considered cavalry. German airborne units in WWII (Faellschirmjaeger) were technically airmen, as they fell under the Luftwaffe.
