Do you yourself have a military background similar to Reacher's? Hard to imagine not. You are precise in describing military protocol. Boy, would I hate to be on Reacher's s--- list!
Jodie Garber Jacobs is something else in my imagination.
My father spent time in the army and I remember clearly all the stories he told. Now I get correspondence from current serving soldiers. The dynamic between enlisted men and the higher-ups hasn’t changed in all these years - probably not since the Romans. Or even earlier.
