The Army has turned loose the PDF of the ATP 3-37.15 publication.
ATP 3-37.15 provides fundamental principles and techniques for preventing and defeating foreign security force threats. It is based on lessons learned from several years of persistent, limited contingency operations. The principal audience for ATP 3-37.15 is all members of the profession of arms. Commanders and staffs serving as joint task force or multinational headquarters should also refer to applicable joint or multinational doctrine concerning the range of military operations and joint or multinational forces. Trainers and educators throughout the Army can also use this publication. Commanders, staffs, and subordinates ensure their decisions and actions comply with applicable United States (U.S.), international, and, in some cases, local laws and regulations. Commanders at all levels ensure that their Soldiers operate in accordance with the law of war and the rules of engagement. (See FM 6-27.) ATP 3-37.15 implements elements of NATO Standardization Agreement (known as STANAG) 6513 and NATO Allied Tactical Publication (known as ATP)-3.16.1 into U.S. Army doctrine
