The most well known tank of World War II, and the one that the mere mentioning it's name would cause fear, was the Tiger. The Russians first encountered, and captured one outside of Leningrad when Hitler prematurely had them sent to the front. The British and Americans encountered them in Tunisia with the British capturing one.
Here's a picture of one with the Gross Deutschland Division.
