The focus of this monograph is the evaluation of the principles of Operations Other Than War (OOTW) as listed in the June 1993 edition of U, S. Army Field Manual 100-5 in peacekeeping operations. Military commanders and decision makers must understand these principles not only in the current environment, but also in historical context. Understanding these principles should lead to better understanding of their utility and application. The monograph presents the principles and applies them to the 1960 United Nations peacekeeping operation in the Congo (ONUC) to gain historical perspective. The principles are evaluated through a modification of the Cohen and Gooch five step process which they presented and used in their book "Military Misfortunes." The monograph conclusion covers the support for the OOTW principles in ONUC and some considerations for future peacekeeping operations. The critical principles in ONUC were objective, legitimacy, and restraint. The other principles were less supported. ONUC also highlighted the difficulty of a "Chapter 6 ½" operation which appears to have a seamless transition from "peace" to "war." The need for additional emphasis in FM 100-5 on the multi-national nature peacekeeping is pointed out. The monograph concludes with the need to constantly evaluate the OOTW principles not only horizontally but also vertically in any peacekeeping operation.
