Sweden is continuously contributed troops to international peace operations.The government has declared its ambition to increase Swedish contributions in the future, including through doubling the number of soldiers in international operations. Deciding on what equipment and supplies will be provided to each contingent sent to do international service is an essential component of military planning. Having access to the appropriate types of resources and assets, where and when required, is a fundamental prerequisite for successful military operations, including the protection of the own forces as well as execution of mandated tasks. Nonetheless, the high cost of equipment and supplies must be balanced against the benefits they are intended to contribute. This study aims to examine the Swedish planning processes related to contributions to international operations, and how these affect the quantity of equipment and supplies needed. The purpose of the report is twofold: to create a better understanding of the Swedish planning processes, as well as pinpointing the main fa ctors affecting outcomes as regards equipment and supplies. During spring of 2008, Sweden contributed troops to the European Union mission in Chad. Planning for this mission took place in the autumn of 2007. The experiences in planning and execution of this particular mission have been used as a case study in this report. Outlining the various factors that effected the need of certain equipment and supplies, the report shows that the primary needs are guided by strict factors (such as mission area terrain, distance to the theatre of operations and influence of international actors). Nonetheless, need of equipment and supplies are also greatly guided by a desire of the Swedish Armed Forces to manage all uncertainties. As a result, equipment is often added without sufficient debate of what utility that is removed in favour of additional equipment. In addition, there is a greate discrepancy between the equipment and supplies planned for the operation and what is later sent to the theatre; which could indicate that the planning process is not adequately functioning.
