The A330 MRTT / KC-30A can be fitted with pods for Probe-Drogue on the wings and the fuselage, and with a Boom on the fuselage. Before flight, if you fit the Probe-Drogue pods on the wings and the Boom pod in the fuselage then you can refuel both types of aircraft in the same flight.
The below RAAF KC-30A is configured as above. The boom is retracted.
Our IL-78 refuelers are also fitted with a poded drogue-probe system which can be removed if the aircraft needs to be used as a cargo carrier. Hence, at least theoretically, a podded boom system could be developed for the IL-78. None exist as of yet.
You can also attach probe-drogue adapters at the ends of the booms of the KC-10 and the KC-135 but can't have them refueling both types in the same flight.
