Peace operations (PO) are crisis response and limited contingency operations, including international efforts and military missions containing conflict, redressing the peace, and shaping the environment supporting reconciliation, rebuilding, and facilitating the transition to effective governance. PO includes peacekeeping operations, peace building, post conflict actions, peacemaking processes, conflict prevention, and military peace enforcement operations. Chapter I describes 5 PO categories and 15 joint fundamentals of PO. The chapter discusses transition planning for PO missions, and other PO categories for relieving forces, and civilian agencies. Chapter II sets the conditions for successful nonmilitary peace building activities. It provides design and planning factors commanders and staffs must consider when undertaking PO. It highlights factors that account for capability differences between United States (US) forces, multinational forces, and civilian agencies. Chapter III describes tactical-level tasks for PO forces. This includes six types of patrols, mobile or fixed observation techniques, and movement control with roadblocks and checkpoints. It provides techniques for vehicle, personnel, and urban searches. In addition, the chapter presents techniques for controlling civil disturbances and handling refugees or displaced persons. Chapter IV focuses on methods for controlling large areas and separating opposing forces, including but not limited to, interposition, establishing areas of separation, buffer zones, border control, and demilitarized zones. Chapter V provides checklists and basic considerations for force protection. This includes threat assessment, force protection condition procedures, and potential terrorist tactics. The chapter focuses on tactics, techniques, and procedures (TTP) for intelligence usage, preventive or reactive medicine, and military information support operations (MISO). Chapter VI lists the principles of civil-military operations and the aspects of governance associated with PO. It provides TTP integrating civilian and military activities for foreign humanitarian assistance, civil affairs operations, and election support. Chapter VII discusses the importance of information operations (IO), and informing and influencing relevant audiences to ensure successful PO. IO is the integrated employment, during military operations, of information-related capabilities in concert with other lines of operation to influence, disrupt, corrupt, or usurp the decision making of adversaries. Chapter VIII provides techniques and considerations for conflict resolution focusing on negotiation, mediation, and arbitration. Appendix A provides the purpose for conducting meetings and interpersonal engagements and provides TTP for effective planning and execution. Appendix B provides an overview of the role and responsibilities of liaison officers and approaches they use that contribute to effective coordination and collaboration among various agencies involved in PO. Appendix C discusses the vital role interpreter's play in facilitating interactions and negotiations between the local or indigenous population and US forces. Appendix D Civil Component Analysis and Templating, describes the process commanders and their staffs use to analyze the civil component of an area of operations and determine how it can help, hinder, or affect PO. Appendix E gives a brief description of various intergovernmental organizations and nongovernmental organizations that work with PO forces. Appendix F discusses joint commissions and how they facilitate more effective PO. Appendix G provides TTP on ways PO forces can protect civilians and effectively respond to mass atrocity situations. Appendix H highlights important PO documents. Appendix I provides training considerations and opportunities for the preparation of PO.
