Major General Harry Letson was President of the DCRA from 1954 to 1956. For many years he was a staunch supporter of the Association, contributing much time, energy and finances to the DCRA .
Two very prestigious matches bear his name. In the Canadian Forces Small Arms Competition (CFSAC), the overall winning team is presented the Letson Trophy which qualifies that team to represent the Canadian Forces at Bisley the following year. In the Canadian Fullbore Rifle Championships, the winner of the Letson Match is granted a Life Membership in the Association.
When Major General Letson passed away in 1996, a considerable sum of money was provided to the DCRA to assist young shooters, who had qualified for the Bisley Team, in financing their trip to England.
