The name Tiger was easy to use, so I think it fair to say that most of the Allies called the German tanks "Tigers"

There were not many "Heavy tank battalions" In Normandy, If you did come across them? then there would be no trouble in telling them apart. The Mark-4s, the Panthers, and the Tiger are as different as chalk to cheese!

We did discover in a wood in Belgium a "King Tiger" (I only ever saw one)This King Tiger was sat there in amongst a huge German ammo amd weapons dump. There were weapons of every description in that wood. Huge quantities of weapons and equipment..

None of the British liked the flame throwers much. Well, We didn't! Now if you go to a certain wood in Belgium, and dig down deep, there you will find a load of flame throwers, as used by infantry...The round tank type that was carried on a soldiers back. I bet after 60 years thet are in a poor state by now.
