‘ASC’ titles were obsolete by 1919 when the corps was granted the ‘Royal’ prefix in recognition of service in the Great War; the title change was approved by the King in late December 1918. New ‘RASC’ titles would be in use after this change. The Army Veterinary Corps was granted the ‘Royal’ prefix at the same time.
