TC 18-01 is authoritative but not directive. It serves as a guide and does not preclude SF units from developing their own standing operating procedures (SOPs) to meet their needs. It explains planning and the roles of SF, Military Information Support operations (MISO), and Civil Affairs (CA) in UW operations. There are appropriate manuals within the series that addresses the other primary SF missions in detail.
