When new concepts are introduced they can be thought of as abstract and difficult. To overcome this, metaphors can be used for explanation. The purpose of this report is to describe a metaphor to present and illustrate the architecture of the Swedish armed forces (FMA). A transport company is used as a metaphor to describe and explain concepts and aspects of FMA. The metaphor was developed iteratively with feedback from persons involved in the development of FMA. Based on their opinions the metaphor was updated. Thereafter the metaphor was evaluated by persons having domain knowledge from the armed forces. Their opinions were used as a basis for modification of the metaphor to the final version. The metaphor describes the architectural views and the concepts of sitsyst (situated adopted systems), services based on LOVENTP, general design principles, goal architecture and management of system changes. FMA includes the architectural views of system, business, organization, personnel, information and technology. The concept of service is central to FMA and is an abstraction of how a producer yields value for a customer.
