Almost all of us now know that the guys in Afghanistan after 9/11 on horseback with GPS technology in one hand and gun in the other were Army Special Forces, a part of Special Operations Forces. They were (and are) impressive. David Tucker & Christopher J. Lamb (both served in an office in DOD that had "special operations and low intensity conflict" in its title; you gotta love that!) just published a volume in which they cover, as far as I can tell, everything important (and therefore controversial) about what SOF are and have been, how they are organized, and how againt Islamic extremism and other irregular threats SOF can provide the greatest strategic value.
"SOF are less a model for information-age transformation of conventional forces than they are a model for how to fight irregular warriors with discrimination, at low cost, and through emphasis on indirect methods." Theoretically exciting as this is, I glance at a photo of some scruffy guys fondling their cold guns and unlit cigars in some desert village far away. Their American eyes see both good and evil. This good book is dedicated to such good men (and their families).
