This publication, Army Techniques Publication ATP 3-90.15 Site Exploitation July 2015, discusses how site exploitation is planned, resourced, and implemented, and how the resultant information or intelligence is disseminated to the lowest tactical level. Soldiers conduct site exploitation with political, military, economic, and social information, infrastructure, physical environment, or time sensitivity implications to the United States. Both hasty and deliberate site exploitation are considered throughout the operations process and are executed through the exercise of mission command. The term site exploitation has been redefined in this publication. (See chapter 1, paragraph 1-1.) This ATP uses the generic term brigade throughout the publication to refer to Army brigade combat teams and brigades in order to recognize that site exploitation is executed by all Army brigades, not just brigade combat teams. Both the terms materiel and material are used within this publication. The terms materiel and material are often confused, but they both have distinct definitions. Materiel includes, but is not limited to, information, documents, electronic data storage multimedia, weapons, personal property, and monies associated with the threat. Material refers to a substance from which something is made or can be made, or a substance that has a particular quality. ATP 3-90.15 has four chapters and seven appendixes. Chapter 1 provides an introduction to site exploitation and includes the definition and description of site exploitation activities. Chapter 1 discusses tactical site exploitation and technical exploitation, site exploitation in the operational environment, and how site exploitation supports unified land operations. Chapter 2 discusses tactical site exploitation planning considerations and the differences between hasty site exploitation and deliberate site exploitation. Chapter 2 also discusses site exploitation and the military decisionmaking process. Chapter 3 focuses on preparations for tactical site exploitation to include importance of integrating enablers into tactical site exploitation. Chapter 4 discusses considerations when executing tactical site exploitation. Chapter 4 also discusses techniques used during execution of tactical site exploitation. Chapter 5 discusses site exploitation assessment techniques and measures for assessing effective site exploitation. Appendix A provides a tactical site exploitation standing operating procedure. Appendix B provides lists of what to include in tactical site exploitation kits. Appendix C provides practical means and methods of evidence collection to support host-nation rule of law. Appendix D provides sample weapons cache checklists for documenting weapons caches. Appendix E discusses DOD forensics and the role of the forensic exploitation team. Appendix F provides information about additional support obtained from government and military organizations when conducting site exploitation. Appendix G describes an attack scene investigation and provides information on how to conduct an attack scene investigation.
