This book provides great detail drawings of the American M36/M36B1 Tank Destroyer.
The US idea when going into WWII was to use tanks to support infantry and use Tank Destroyers against enemy tanks.
I found the photos and information in this book to be fascinating and many of the photos are ones not available anywhere else. The photos range from in production shots, in action and knocked out ones. All variations are covered in the photos and you see a lot of in action shots with the tank customized by each crew.
Along with the many photos from WWII there are great workarounds pictures full of fantastic details. These are indispensable for any modeler building this tank destroyer. You see so much detail in the walk around pictures which will make adding additional work to your model so much easier.
Each photo has a great description of what is in the picture, units using them, where and when.
