annual, R & R leave,
'leaves' of the Army.
**R & R = Rest and Recuperation. It used to be five days leave in the middle of a 6-month tour of duty so that a soldier could come home and see his family. I believe that the British Armed Forces have now changed this by sending troops on a 4-month tour of duty, doing away with R & R. This is dependent on the theatre of war. **
