Without wishing to burst your bubble
ALL the current Class 'D' zones that were in existence when the ICAO airspace classification system was adopted in 1991 were SRZ's - both civil and military. There was no "adoption" of civil designation - it was a change from a National designation to an International Designation.
So - on that basis the airspace has never been different from it's civil counterpart, therefore, in the same was as ATSOCAS (sic) have been standardised so there is no reason why Class 'D' operations should be different. Maybe with the Military having only one piece of class 'D' in the near future maybe they should sort their act out and step into line with the rest of the country.
