By convention, it is also given to the Governor General of Canada upon his or her appointment as viceroy, which includes the title of Commander-in-Chief in and over Canada.

The Decoration for Officers of the Royal Naval Volunteer Reserve, post-nominal letters VD until c. 1947 and VRD thereafter, was instituted in 1908. It could be awarded to part-time commissioned officers in the United Kingdom's Royal Naval Volunteer Reserve after twenty years of service as efficient and thoroughly capable officers. The decoration was a Naval version of the Volunteer Officers' Decoration and its successor, the Territorial Decoration.
The Efficiency Medal was instituted in 1930 for award to part-time warrant officers, non-commissioned officers and men after twelve years of efficient service on the active list of the Militia or the Territorial Army of the United Kingdom, or of the other Auxiliary Military Forces throughout the British Empire.

The Medal for Long Service and Good Conduct (Military) is a medal awarded to regular members of the armed forces. It was instituted by King George V in 1930 and replaced the Army Long Service and Good Conduct Medal as well as the Permanent Forces of the Empire Beyond the Seas Medal. The medal was originally awarded to Regular Army warrant officers, non-commissioned officers and men of the UK Armed Forces. It also had a number of territorial versions for the Permanent Forces of the British Dominions. The eligibility criteria were relaxed in 1947 to also allow the award of the medal to officers who had served a minimum period in the ranks before being commissioned. Since 2016, the eligibility was widened to include officers who had never served in the ranks, and so the medal can now be awarded to all regular members of the British Army who meet the required length of service.

The NCA has a strategic role in which it looks at the bigger picture across the UK, analysing how criminals are operating and how they can be disrupted. To do this, it works closely with regional organised crime units (ROCUs), local police forces, and other government departments and agencies.
