British and Commonwealth World War 1 Medical Classifications

Asessments made by medical officers as to the suitability of men to perform military duties. A system of lettering and numbering was devised to enable a man's abilities to be quickly noted.

The following are lists of categories used by the Australian and British Armies in 1914. The categories can be used in combination. I have no official reference for the Australian table.
