Impact of Setting in Navy Seal Dogs

In Navy Seal Dogs, the setting is in modern day Iraq and Afghanistan and happened in the earlier 2000's. This setting has to make the characters always be on their guard. Since they are in unwanted territory by the residents, the Seal's K9 has to stay up some nights and keep watch. Like I might've said in my earlier posts, if someone was invading your home/territory, wouldn't you get mad? Because depending on the situation, I think that I would get mad. Plus, the setting makes you wonder what will happen at any moment. While Mike (the Navy Seal) and his team are moving across a small town that happened earlier in the book, him and his team were ambushed by a small team of the "residents" I must say. While no body died from it, it just symbolizes how dangerous the world is out there. Even with some of the most advanced forces, American casulties still result. We never know what the people of Middle Eastern countries are thinking about us behind the curtain, such as Afghanistan. Sometimes I wonder why we're still there too, as even stated by Mike.
