"Under the new 'Joint Force' concept of operations model, the U.S. Navy has taken on added prevention responsibilities that include strategic and operational responses to asymmetric warfare. It is becoming evident that this Joint Force concept does not require an unduly large number of operational units in order to effectively support the nation's terrorism prevention mission. The lessons learned from the Navy's adoption of this concept, and its continuing evolution, are of considerable value to homeland security practitioners who are responsible for preventing terrorist activity within their respective jurisdictions. Communities should seek to develop surge capacity in their strategic and tactical theaters, conducting exercises to diagnose and strengthen this critical response component. Local organizations should consider three mission areas of prevention - interdiction, response, and redundancy - and develop qualifiers that can be applied to evaluating these areas. Furthermore, the Navy's emphasis on interagency cooperation and mission interoperability offers an example that can be followed by local homeland security jurisdictions."
