This extensive account of U.S. Army Special Operations soldiers and their actions in Afghanistan is an important contribution to understanding how these unique individuals removed the Taliban from power and destroyed al-Qaeda and Taliban strongholds in Afghanistan as part of the US global war on terrorism. The originating idea, research, and writing that went into it are strictly the product of the U.S. Army Special Operations Command and its assigned authors. The selected historical vignettes tell the ARSOF story. Many of these soldier stories demonstrate the capabilities of special operations forces (SOF)-unique equipment, while others point out the skills and bravery of the soldiers and aviators. The strength of ARSOF resides in its highly trained, very motivated soldiers. While technology plays a part in ARSOF, the soldiers make the difference. There has been a conscious effort to ensure that the stories of all ARSOF elements are presented. Thus, to provide a fair representative sampling of different activities within the security constraints, not all interviews became vignettes. One hundred-percent coverage of all participating teams was impossible. The examples selected were the best of those available to demonstrate a capability, illustrate an activity, or clarify a combat mission. The sensitive classified parts have been sanitized based on specifi c security rules, hence special forces elements do not always mean special forces teams, and pseudonyms are used predominantly. A limited-access U.S. Army Special Operations Command (USSOCOM) classifi ed annex of sources will contain true names and specify documents and briefi ngs to corroborate the material included. The controlled classifi ed annex will not be available to researchers who do not have the appropriate security clearances and a clear "need to know."
