Wired for War: The Robotics Revolution and Conflict in the 21st Century

Amazon.com: Wired for War: The Robotics Revolution and Conflict in the 21st Century 9781594201981: P. W. Singer: Books.

Another great recent read of mine.  I highly recommend this book if you are interested in how combat is going to be (since it has already changed) 5-10-20 years from now.  The book gives a great overview of what is in use today, the ethics of continuing down the autonomous war fighter path, the unanswered legal questions present today, and of course the Skynet conversation.
