I would add that you probably should look to some additional sources that disagree with our freind Gian Gentile starting with Kilcullen's Accidental Guerrilla. Then I would look at Mason and Malkesian for a good source of recent case study writing. Another set of case studies from a period only a little removed is Corr & Sloan, Low Intensity Conflict: Old Threats in a New World. Look also at some of the quant studies including those done by RAND and my own work with Max Manwaring,especially The SWORD Model of Counterinsurgency published in these pages. What is particularly interesting is how well the snowflake/snow metaphor holds up in nearly all serious analysis.
