Beyond the Call of Duty

3 stars because the stories were heartwarming as promised (and totally heartbreaking as well!), but this looks more like a series of excerpts from three other books rather than the fruit of a researched job.
I say this because there are a lot of doggy war heroes...but, imagine!, just three of the protagonists from three bestsellers were picked up!
At worst, this book does a good promotion for the source material and I appreciate it.
