Query: A huge disappointment

I just recently read this after having read the two previous Martin Vail books several years ago. Overall, I would not recommend it. It does a poor job of advancing anything from the previous two stories and in fact, the book would not have been any different had the Martin/Aaron characters not even been in it. Overall, it almost felt like a 'I want to retire but want one more big payday' type of book, which is a shame.As others have mentioned - a lot of the details that are provided are just plain wrong. I realize that I might have more of an eye for this as a soldier - but I start to feel like 'if the author took shortcuts with this, what else is there?' If you are going to write a book about conflict between militias and soldiers - at least learn the equipment.Also - many of the additional characters that were added were complete stereotypes and never really seemed to have any depth.Overall - a poor effort that I cannot recommend in good faith.
