The multi-domain operations are vaguely defined and there are a variety of interpretations. In general terms, multi-domain can be described as a means of communication between different joint forces such as land, water, air, cyber, and space. In multi-domain operations, the focus is on how those domains can integrate using technologies, methods, and planning.  By interviewing individuals with long experience in both the British and Swedish Armed Forces and conducting a literature study, the focus has been on understanding how multi-domain operations as a concept are understood, interpreted, and implemented in the respective nation’s operations today regarding the technology and organizational structure.   The results were compared with frameworks such as Federated Mission Networking (FMN) and Level of Information Systems Interoperability (LISI). The analysis shows that both the Swedish and British Armed Forces need greater interoperability. In order to have a better ability to cooperate within their forces, a more agile approach to the organization is needed that takes advantage of information and communication technologies. This can be achieved by managing different protocols through the different layers and models and by introducing a cloud service that functions as a cloud service function where the information flow is fast and easily accessible, independent of the domain.
