Does anyone have a breakdown of the various SD branches of the Staff Duties directorate? My understanding is that SD6 was for Signals, and SD7 was for the RAC, and I think either SD4 or SD5 were for Training. Has anybody got a full list? Thanks in advance for any help.
Adding to what has already been presented, prior to breaking out into their own directorates, Sigs were indeed SD.6 and AFV SD.7 Training, depending upon the precise nature, was generally under the purview of the Directorate Military Training DMT
Has anyone heard of an SD8? This might only have been something the Canadians had. I've come across it in Canadian memos.
