The North West Europe campaign was a campaign by the British Commonwealth armed forces in North West Europe, including its skies and adjoining waters during World War II. The term Western Front has also sometimes been used informally. The United States military refers to this campaign as the European Theater of Operations.
Hence the battle honour "North-West Europe" was awarded to any unit involved in land, sea and air campaigns and operations in, over or near Belgium, Denmark, France, Germany, Luxembourg, Netherlands, Norway and the United Kingdom during World War II. It includes many more specific campaigns and/or battle honours.
