Members of the Royal Canadian Navy's Beach Commando "W" carried Lanchester sub-machine-guns like this example.

The Lanchester, based on a German design, was the Royal Canadian Navy's standard sub-machine-gun, and could be fitted with the long bayonet seen here. Beach Commandos were created to coordinate operations on the beachhead during amphibious landings like D-Day. Beach Commando "W", created in late 1943, was sent to Juno Beach, the Canadian landing area in Normandy, in early July 1944, and returned to the United Kingdom in August.
