The Conspicuous Gallantry Medal (CGM) was, until 1993, a British military decoration for gallantry in action for petty officers and seamen of the Royal Navy, including Warrant Officers and other ranks of the Royal Marines. It was formerly awarded to personnel of other Commonwealth countries. In 1943 a Royal Air Force version was created for conspicuous gallantry in action against the enemy in the air.
The Conspicuous Gallantry Medal was the second level bravery award for ratings of the Royal Navy, ranking below the Victoria Cross and, after its institution in 1914, above the Distinguished Service Medal. It was normally awarded with an annuity or gratuity.  In 1943, during the Second World War, a Royal Air Force version, the Conspicuous Gallantry Medal (Flying), was added.  Since 1917, recipients have been entitled to use the post-nominal letters "CGM". 
The original Royal Navy medal was instituted in 1855 to recognise gallantry during the Crimean War, as the Naval counterpart of the Distinguished Conduct Medal. Only twelve were finally awarded, with the medals created by adapting existing examples of the Royal Marines Meritorious Service Medal, with the words 'MERITORIOUS SERVICE' erased from the reverse inscription, and 'CONSPICUOUS GALLANTRY' engraved in its place. 
The Conspicuous Gallantry Medal was re-instituted on 7 July 1874 as a permanent decoration, and was initially used to reward gallantry in the various colonial campaigns of the late nineteenth century in which the Royal Navy took part. 
It remained an exclusively Naval award until World War II when a number of changes were made. Eligibility was extended in April 1940 to Royal Air Force personnel serving with the Fleet; in July 1942 to Army personnel serving afloat, for example manning a merchant ship's anti-aircraft guns; and in September 1942 to ratings of the Merchant Navy. 
In January 1943 the Conspicuous Gallantry Medal (Flying) was established for acts of conspicuous gallantry whilst flying in active operations against the enemy, of a standard below that required for the Victoria Cross, but above that for the Distinguished Flying Medal.
In 1979 eligibility for a number of British awards, including the CGM, was extended to permit posthumous awards.  Until that time, only the Victoria Cross and a mention in dispatches could be awarded posthumously.
In 1993, the Conspicuous Gallantry Medal, Distinguished Service Order (when awarded specifically for gallantry) and Distinguished Conduct Medal were all replaced by the Conspicuous Gallantry Cross (CGC). The CGC is tri-service and is awarded to all ranks. It is second only to the Victoria Cross for bravery in action. 
The CGM had also been awarded by Commonwealth countries but by the 1990s most, including Canada, Australia and New Zealand, had established their own honours systems and no longer recommended British honours.
Apart from the ribbon, the medals awarded for service afloat and for flying are identical. The medal is circular, silver, 36 millimetres (1.4 in) in diameter with the following design: 
The medal was awarded with one of five obverses: 
Between 1855 and 1993 a total of 369 medals and one second award bar were awarded.

The above figures for World War II include ten honorary awards to servicemen from allied countries, eight for service afloat and two for gallantry while flying. 
The Distinguished Flying Cross (DFC) is the third-level military decoration awarded to officers, and since 1993 to other ranks, of the United Kingdom's Royal Air Force and other services, and formerly to officers of other Commonwealth countries, for "an act or acts of valour, courage or devotion to duty whilst flying in active operations against the enemy".
The George Cross (GC) is the highest award bestowed by the British government for non-operational gallantry or gallantry not in the presence of an enemy. In the UK honours system, the George Cross is equal in stature to the Victoria Cross, the highest military gallantry award. This has been the case since the introduction of the award in 1940. It is awarded "for acts of the greatest heroism or for most conspicuous courage in circumstance of extreme danger", not in the presence of the enemy, to members of the British armed forces and to British civilians. Posthumous awards have been allowed since it was instituted. It was previously awarded to residents of Commonwealth countries, most of which have since established their own honours systems and no longer recommend British honours. It may be awarded to a person of any military rank in any service and to civilians including police, emergency services and merchant seamen. Many of the awards have been personally presented by the British monarch to recipients or, in the case of posthumous awards, to next of kin. These investitures are usually held at Buckingham Palace.
The Distinguished Service Order (DSO) is a military decoration of the United Kingdom, as well as formerly of other parts of the Commonwealth, awarded for meritorious or distinguished service by officers of the armed forces during wartime, typically in actual combat. Since 1993 it has been awarded specifically for 'highly successful command and leadership during active operations', with all ranks being eligible.
The Australian honours and awards system refers to all orders, decorations, and medals, as instituted by letters patent from the Monarch of Australia and countersigned by the Australian prime minister at the time, that have been progressively introduced since 14 February 1975. The Australian honours and awards system excludes all state and local government, and private, issued awards and medals.
The Distinguished Conduct Medal was a decoration established in 1854 by Queen Victoria for gallantry in the field by other ranks of the British Army. It is the oldest British award for gallantry and was a second level military decoration, ranking below the Victoria Cross, until its discontinuation in 1993 when it was replaced by the Conspicuous Gallantry Cross. The medal was also awarded to non-commissioned military personnel of other Commonwealth Dominions and Colonies.
The Distinguished Service Cross (DSC) is a third-level military decoration awarded to officers; and, since 1993, ratings and other ranks of the British Armed Forces, Royal Fleet Auxiliary and the British Merchant Navy have been included. Additionally, the award was formerly awarded to members of other Commonwealth countries.
The Distinguished Service Medal (DSM) was a military decoration awarded until 1993 to personnel of the Royal Navy and members of the other services, and formerly to personnel of other Commonwealth countries, up to and including the rank of Chief Petty Officer, for bravery and resourcefulness on active service at sea.
The Military Cross (MC) is the third-level military decoration awarded to officers and other ranks of the British Armed Forces, and formerly awarded to officers of other Commonwealth countries.
The Air Force Cross (AFC) is a military decoration awarded to officers, and since 1993 other ranks, of the United Kingdom Armed Forces, and formerly also to officers of the other Commonwealth countries. It is granted for "an act or acts of exemplary gallantry while flying, though not in active operations against the enemy". A bar is added to the ribbon for holders who are awarded a further AFC.
To be mentioned in dispatches describes a member of the armed forces whose name appears in an official report written by a superior officer and sent to the high command, in which their gallant or meritorious action in the face of the enemy is described.
The Conspicuous Gallantry Cross (CGC) is a second level military decoration of the British Armed Forces. Created in 1993 and first awarded in 1995, it was instituted after a review of the British honours system to remove distinctions of rank in the awarding of gallantry decorations. The Victoria Cross is the only higher combat gallantry award presented by the United Kingdom.
The Air Force Medal (AFM) was a military decoration, awarded to personnel of the Royal Air Force and other British Armed Forces, and formerly to personnel of other Commonwealth countries, below commissioned rank, for "an act or acts of valour, courage or devotion to duty whilst flying, though not in active operations against the enemy". The award was discontinued in 1993 when all ranks became eligible for the Air Force Cross (AFC) as part of the reform of the British honours system.
The Distinguished Flying Medal (DFM) was a military decoration awarded to personnel of the Royal Air Force and other British Armed Forces, and formerly to personnel of other Commonwealth countries, below commissioned rank, for "exceptional valour, courage or devotion to duty whilst flying in active operations against the enemy". The award was discontinued in 1993 when all ranks became eligible for the Distinguished Flying Cross (DFC) as part of the reform of the British honours system.
The following is the Canadian order of precedence for decorations and medals. Where applicable, post-nominal letters are indicated.
The Victoria Cross for New Zealand (VC) is a military decoration awarded for valour or gallantry in the presence of the enemy to members of the New Zealand Armed Forces. It may be awarded to a person of any rank in any service and civilians under military command, and is presented to the recipient by the Governor-General of New Zealand during an investiture held at Government House, Wellington. As the highest award for gallantry in New Zealand it takes precedence over all other postnominals and medals.
The Meritorious Service Medal (MSM) is a British medal awarded to sergeants and warrant officers of the British armed forces for long and meritorious service. From 1916 to 1928, eligibility was extended to cover both valuable services by selected other ranks irrespective of length of service, and for gallantry not in the face of the enemy.
The Queen's Commendation for Valuable Service in the Air, formerly the King's Commendation for Valuable Service in the Air, was a merit award for flying service awarded by the United Kingdom between 1942 and 1994. It was replaced by the Queen’s Commendation for Bravery in the Air and the Queen's Commendation for Valuable Service.
The Victoria Cross (VC) is the highest and most prestigious award of the British honours system. It is awarded for valour "in the presence of the enemy" to members of the British Armed Forces. It may be awarded posthumously. It was previously awarded by countries of the Commonwealth of Nations, most of which have established their own honours systems and no longer recommend British honours. It may be awarded to a person of any military rank in any service and to civilians under military command. No civilian has received the award since 1879. Since the first awards were presented by Queen Victoria in 1857, two-thirds of all awards have been personally presented by the British monarch. These investitures are usually held at Buckingham Palace.
In 1895, Queen Victoria authorised Colonial governments to adopt various British military decorations and medals and to award them to their local military forces. The Colony of Natal introduced this system in August 1895 and, in 1897, instituted the Distinguished Conduct Medal (Natal), post-nominal letters DCM.
