The Second Warren Fisher Committee was set up in May 1931 to look into ways of improving recruitment into the three medical services. Its main recommendations were:
- A reduction in the establishment from 865 officers to 754 officers. The shortfall to be made up by utilizing retired officers and civilian medical practitioners more fully to fill one man posts at home.
- Of the new establishment, 420 posts to be made permanent while the rest to be short service posts.
- An increase in colonels from 28 to 49 and in Lt Cols from 93 to 119. Officers commanding the larger hospitals to be Colonels.
- One year's service to qualify for promotion to captain and 10 years for promotion to major.
- Colonels to remain on the active list till they reached 57 years, irrespective of whether they had completed 4 years in the rank or not. Lt Cols to retire at 55 years.
- Short service officers to serve for five years. Those not selected, or not wishing for a permanent commission, to be transferred to the Reserves for 12 years and to receive a gratuity of £1000.
- The majority of officers serving overseas to be junior officers, that is short term commission officers, of less than 6 years service. Regular officers to have longer home service.
