Military operations are complicated by increasingly complex demands on the electromagnetic spectrum (EMS). All modern forces depend on the EMS. The EMS is a physical medium through which joint forces conduct operations. The importance of the EMS and its relationship to the operational capabilities is the key focus of joint electromagnetic spectrum management operations (JEMSMO). The EMS is a highly regulated and saturated natural resource. The EMS includes the full range of all possible frequencies of electromagnetic radiation. Joint electromagnetic spectrum operations (JEMSO) include all activities in military operations to successfully plan and execute joint or multinational operations in order to control the electromagnetic operational environment (EMOE). JEMSO is comprised of electronic warfare (EW) and JEMSMO and aims to exploit, attack, protect, and manage resources within the EMOE and resolve electromagnetic interference (EMI) in order to achieve the commander's objectives.
