Common Unit Abbreviations

This section will assist in the identification of unit abbreviations used on RAF Service Records, particularly World War 2 records.  Due to the method of entry, the different styles and quality of handwriting used and the age of the records, care should be taken when reading the records as letters can often be misread.

The list below is by no means exhaustive and should you come across others not listed, feel free to contact me and I can hopefully clarify them.
