This book is a decent introduction into the study of the SS. It doesn't have much (if any) new information and it doesn't go very deep into the subject but if you are only starting to study WWII or the SS this is a good primer (probably best suited to high school students). It also mainly concentrates on the fighting units of the SS while devoting very little space to the Waffen SS's atrocities and participation in the Holocaust. I also would have liked to have more infomation about the foreign SS units. The book has several good photographs in it.
Again, not for serious students of military history but a good start for study of the SS if you are interested in learning about WWII military units. Just don't expect too much.

This book is a rehash of old data with a new title
Mr. Ailsby never fails to copy data from other authors and add a fancy title that is catching and will sell. So long as the title has "SS" on it (he figures), it will sell. Don't waste your time or money on this piece of tripe!
