.........But, my absolute favorite writer of military fiction is W.E.B. Griffin....being a veteran himself he is well versed in all aspects of armed services and lifestyles therein. His Men at War series is really good.
Interesting to hear JanelB, thanks for mentioning. I've passed his up before this, but will pick one up to try.
I've read only 2 of Child's and didn't see much to them.
