This is the first edition of the UN Military Peacekeeping-Intelligence Handbook (UN MPKI HB). This Handbook provides instructions, guidance and advice to personnel deployed in military peacekeeping-intelligence roles in UN peacekeeping operations at the Force HQ, Sector and Battalion levels; however, it has wider applicability and utility, and should be used as a guide for all UN military peacekeeping-intelligence operations.The Handbook covers a broad spectrum and has been designed to assist both personnel with previous peacekeeping-intelligence training as well as those who are deploying in peacekeeping-intelligence roles for the first time. Since each UN peacekeeping operation is organized differently and hence has different peacekeeping-intelligence capabilities deployed, the principles and examples in this Handbook should be taken as guidelines and best practices, and not as a template. This MPKI HB is part of the Peacekeeping-Intelligence Policy Framework and complies with the Peacekeeping-Intelligence Policy (2019). It should be complemented by the Joint Mission Analysis Centre (JMAC) Handbook and UN Military Peacekeeping-Intelligence training. Throughout, the overarching goals of MPKI will always remain the same: to enhance situational awareness and enable UN decision-making for the protection of UN personnel and the protection of civilians
