Kit PK-72. I have just one of these. Too late in the war--like the Pershing--to get some good battles going. I imagine isolated 16 or 45 year-olds with Panzerfausts taking them on.
I recall reading that these were issued to the British 11th Armoured about two weeks before the Germans launched the Ardennes offensive (Battle of the Bulge.) The 11th were drawn into the battle and swapped out their new Comets for their old Shermans because the crews wouldn't be familiar enough with them before they got into combat. (Shame these weren't in combat during Goodwood.) Thoughts, comments?
