British tanks and narrow accounts of World War II

Which non-Bismarck historical misconceptions does Dragon find most frustrating?

Claims that British tanks were uniformly poor and that Britain played little part in World War II.

Dragon identifies two related frustrations with popular military history. One is the blanket dismissal of British tanks throughout World War II and the Cold War. The other is coverage that reduces World War II largely to Germany, the Soviet Union, and the United States. The answer challenges those broad judgments without comparing individual tanks or measuring the wartime contributions of different countries.
