Mk III helmet

The Mark III helmet was issued primarily to assault troops for the Normandy invasion in June 1944, and a large number of helmets from British stocks were issued to the 3rd Canadian Infantry Division in addition to British units.

All Mark III helmets in Canadian stores were returned to the UK shortly after the end of World War II.

The Mk III was itself replaced after the war by the Mark IV helmet, which it closely resembled.

The differences were that the rivets attaching the chinstrap to the helmet were placed much lower down on the shell and the use of a "lift-the-dot" fastener for the liner.

Hence, the title of the helmet (at least in British army stores catalogues) remained the MK IV.

In 1985 the nylon fiber Mark 6 helmet was introduced into service to replace the MK IV, although it was some years before the issue was universal.
