Col Hammes does an excellent review of what he calls "fourth generation warfare"; including brief studies of Vietnam, the Russian conflict in Afghanistan, the Israeli-Palestine conflicts, and the Sandinistas. He doesn't mention the French-Algerian war, but that certainly has all the earmarks of this type of conflict. One point he made was that even though the Russians adopted a scorched-earth policy and indiscrimate bombings and shellings, that wasn't enough to ensure victory. So savagry doesn't always equal victory. This book is notable in that Col Hammes actually has the boldness to offer some suggestions on how we can better fight these wars. Generally, he wants less focus on high-tech gadgetry and more focus on winning the media ratings war, hearts and minds, and an overhaul of the DOD rating system and bureaucracy. It's worth a read for this aspect alone.
