1-133. A JSOA is an area of land, sea, and airspace assigned by a JFC to the commander of SOF to conduct special operations activities. It may be limited in size to accommodate a discreet direct action mission or may be extensive enough to allow a continuing broad range of unconventional warfare operations. A JSOA is defined by a JFC who has geographic responsibilities. JFCs may use a JSOA to delineate and facilitate simultaneous conventional and special operations. The joint force special operations component commander is the supported commander within the JSOA.
