Foreword This manual takes a general approach to COIN. The Army recognizes that every insurgency is contextual and presents its own set of challenges. You cannot fight the Taliban the way you would fight the former Soviet Union; the application of principles and fundamentals to deal with each vary considerably. Nonetheless, all insurgencies, even today’s highly adaptable strains, remain wars amongst the people, employ variations of standard themes, and adhere to elements of a recognizable revolutionary campaign plan. This manual therefore addresses the common characteristics of insurgencies. It strives to provide those carrying out a counterinsurgency campaign a solid foundation on which to build in seeking to understand and address specific insurgencies. A counterinsurgency campaign is, as described in this manual, a mix of offensive, defensive, and stability operations, conducted along multiple lines of operation. It requires Soldiers to employ a mix of both familiar combat tasks and skills more often associated with nonmilitary agencies, with the balance between them varying depending on the local situation. This is not easy. Leaders at all levels must adjust their approach constantly, ensuring that their elements are ready each day to be greeted with a handshake or a hand grenade, to be nation builders as well as warriors, to help reestablish institutions and local security forces, to assist in the rebuilding of infrastructure and basic services, and to facilitate the establishment of local governance and the rule of law. The list of such tasks is a long one and involves extensive coordination and cooperation with a myriad of intergovernmental, indigenous, and international agencies. Indeed, the responsibilities of leaders in a counterinsurgency campaign are daunting – and the discussions in this manual endeavor to alert them to the challenges of such campaigns and to suggest general approaches for grappling with those challenges. Conducting a successful counterinsurgency campaign thus requires a flexible, adaptive force led by agile, well-informed, culturally astute leaders. It is our hope that this manual provides the necessary guidelines to succeed in such a campaign, in operations that inevitably, are exceedingly difficult and complex. Our Soldiers deserve nothing less.

This publication is the second in a series of lessons learned reports which examine how the U.S. government and Departments of Defense, State, and Justice carried out reconstruction programs in Afghanistan. In particular, the report analyzes security sector assistance (SSA) programs to create, train and advise the Afghan National Defense and Security Forces (ANDSF) between 2002 and 2016. This publication concludes that the effort to train the ANDSF needs to continue, and provides recommendations for the SSA programs to be improved, based on lessons learned from careful analysis of real reconstruction situations in Afghanistan. The publication states that the United States was never prepared to help create Afghan police and military forces capable of protecting that country from internal and external threats. It is the hope of the Special Inspector General for Afghanistan Reconstruction (SIGAR), John F. Sopko, that this publication, and other SIGAR reports will create a body of work that can help provide reasonable solutions to help United States agencies and military forces improve reconstruction efforts in Afghanistan.

This field manual establishes doctrine for military operations in a counterinsurgency (COIN) environment. It is based on lessons learned from previous counterinsurgencies and contemporary operations. It is also based on existing interim doctrine and doctrine recently developed. Counterinsurgency operations generally have been neglected in broader American military doctrine and national security policies since the end of the Vietnam War over 40 years ago. This manual is designed to reverse that trend. It is also designed to merge traditional approaches to COIN with the realities of a new international arena shaped by technological advances, globalization, and the spread of extremist ideologies--some of them claiming the authority of a religious faith. This is a comprehensive manual that details every aspect of a successful COIN operation from intelligence to leadership to diplomacy. It also includes several useful appendices that provide important supplementary material.

This volume presents a collection of 38 articles, interviews, and speeches describing many aspects of the U.S. Marine Corps' participation in Operation Enduring Freedom from 2001 to 2009. This work is intended to serve as a general overview and provisional reference to inform both Marines and the general public until the History Division completes monographs dealing with major Marine Corps operations during the campaign. The accompanying annotated bibliography provides a detailed look at selected sources that currently exist until new scholarship and archival materials become available. From the Preface - From the outset, some experts doubted that the U.S. Marines Corps would play a major role in Afghanistan given the landlocked nature of the battlefield. Naval expeditionary Task Force 58 (TF-58) commanded by then-Brigadier General James N. Mattis silenced naysayers with the farthest ranging amphibious assault in Marine Corps/Navy history. In late November 2001, Mattis' force seized what became Forward Operating Base Rhino, Afghanistan, from naval shipping some 400 miles away. The historic assault not only blazed a path for follow-on forces, it also cut off fleeing al-Qaeda and Taliban elements and aided in the seizure of Kandahar. While Corps doctrine and culture advocates Marine employment as a fully integrated Marine air-ground task force (MAGTF), deployments to Afghanistan often reflected what former Commandant General Charles C. Krulak coined as the "three-block war." Following TF-58's deployment during the initial take down of the Taliban regime, the MAGTF made few appearances in Afghanistan until 2008. Before then, subsequent Marine units often deployed as a single battalion under the command of the U.S. Army Combined Joint Task Force (CJTF) to provide security for provincial reconstruction teams. The Marine Corps also provided embedded training teams to train and mentor the fledgling Afghan National Army and Police. Aviation assets sporadically deployed to support the U.S.-led coalition mostly to conduct a specific mission or to bridge a gap in capability, such as close air support or electronic warfare to counter the improvised explosive device threat. From 2003 to late 2007, the national preoccupation with stabilizing Iraq focused most Marine Corps assets on stemming the insurgency, largely centered in the restive al-Anbar Province. As a result of the North Atlantic Treaty Organization (NATO) taking over command of Afghan operations and Marine Corps' commitments in Iraq, relatively few Marine units operated in Afghanistan from late 2006 to 2007. Although Marines first advocated shifting resources from al-Anbar to southern Afghanistan in early 2007, the George W. Bush administration delayed the Marine proposal for fear of losing the gains made as a result of Army General David H. Petraeus' "surge strategy" in Iraq. By late 2007, the situation in Afghanistan had deteriorated to the point that it inspired Rolling Stone to later publish the story "How We Lost the War We Won." In recognition of the shifting tides in both Iraq and Afghanistan, the Bush administration began to transfer additional resources to Afghanistan in early 2008. The shift prompted senior Marines to again push for a more prominent role in the Afghan campaign, even proposing to take over the Afghan mission from the Army. . . .

From the foreword: "The present volume, Vanguard of Valor II, offers six accounts of US Soldiers at the tip of the spear during the Afghan campaign. The Combat Studies Institute's Vanguard of Valor series is intended to document small unit actions in Afghanistan. These books play an equally important role by offering insights to Soldiers who may find themselves in the years ahead under similar conditions, whether in Afghanistan or in some other troubled land where they have been deployed to conduct the dangerous business of defending the national interest in a theater of war."

This paper clearly shows the immediate relevancy of historical study to current events. One of the most common criticisms of the U.S. plan to invade Iraq in 2003 is that too few troops were used. The argument often fails to satisfy anyone for there is no standard against which to judge. A figure of 20 troops per 1000 of the local population is often mentioned as the standard, but as McGrath shows, that figure was arrived at with some questionable assumptions. By analyzing seven military operations from the last 100 years, he arrives at an average number of military forces per 1000 of the population that have been employed in what would generally be considered successful military campaigns. He also points out a variety of important factors affecting those numbers-from geography to local forces employed to supplement soldiers on the battlefield, to the use of contractors-among others.

This anthology discusses the converging operational issues of air base defense and counterinsurgency. It explores the diverse challenges associated with defending air assets and joint personnel in a counterinsurgency environment. The authors are primarily Air Force officers from security forces, intelligence, and the office of special investigations, but works are included from a US Air Force pilot and a Canadian air force officer. The authors examine lessons from Vietnam, Iraq, Afghanistan, and other conflicts as they relate to securing air bases and sustaining air operations in a high-threat counterinsurgency environment. The essays review the capabilities, doctrine, tactics, and training needed in base defense operations and recommend ways in which to build a strong, synchronized ground defense partnership with joint and combined forces. The authors offer recommendations on the development of combat leaders with the depth of knowledge, tactical and operational skill sets, and counterinsurgency mind set necessary to be effective in the modern asymmetric battlefield.
