You can tell that Jonathan Brazee has combat experience just from the way he writes his combat scenes - realistic, gritty, choppy, focused on what the character sees. I never understood how people could believe that a soldier in the middle of a really messy situation where it is difficult to remember to breathe can be expected to see the entire battlefield and react accordingly. Throw a non-combatant medic into such a situation and what do you get? Nova Esperança, The Doc. If you enjoy the works of John Ringo, try the works of Jonathan Brazee - they are worth comparing.
