Distinguished Conduct Medal

The Distinguished Conduct Medal, post-nominal letters DCM, was established in 1854 by Queen Victoria as a decoration 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, until it was discontinued in 1993. The medal was also awarded to non-commissioned military personnel of other Commonwealth Dominions and Colonies.
