The fact that military logistics should be studied more is mentioned by many, but the problem still seems to persist year after year. To be able to study war from a logistical perspective, theories and theoretical frameworks need to be developed. The systems and terms for operational logistics are not as clear as the terms used for the strategic and tactical level. Moshe Kress has developed properties to explain the operational logistics. This thesis examines if the properties can explain the operational logistics, through a theory-testing comparative case study of Operation Enduring Freedom and Operation Iraqi Freedom. The results shows that Kress's properties can explain the operational logistics during the operations. The analysis of Operation Enduring Freedom shows that all four properties was fulfilled. Operation Iraqi Freedom, which had clear logistical shortcomings during the operation, however, only shows fulfillment of one property, partial fulfillment of two properties and that one property was not fulfilled at all
