During 2001 the information warfare (IW) group within the FoRMA project carried out two war games - one focusing on an armed attack on Sweden ("Roslagen") and one on Swedish participation in an international peace support operation ("Kaukasus"). The report gives a general overview of the two scenarios. Within these scenarios a number of situations were analysed. In the first war game ("Roslagen") the focus was mainly on CNO (computer network operations) on a tactical level. The purpose of the second war game was to analyse what units and components within the information warfare field that needed to be in place in the area of operations or in the vicinity and which resources that could be at home and used on a "reach-back basis". The focus in the second war game was on CNO, electronic warfare and psychological operations (psyop). Other IW components such as physical destruction of command and control resources and deception, are just mentioned. The report presents conclusions from the different situations as well as summarized conclusions from the two war games.
