Is there any doctrine given by US Government in case of any terrorist attack?

Yes. The Unites States (US) Joint Chiefs of Staff Publication 3-26, Counterterrorism, was issued on October 24, 2014. “This publication …sets forth joint doctrine to govern the activities and performance of the Armed Forces of the United States in joint counterterrorism operations and provides the doctrinal basis for US military coordination with other US Government departments and agencies during operations and for US military involvement in multinational operations.

It provides military guidance for the exercise of authority by combatant commanders and other joint force commanders (JFCs) and prescribes joint doctrine for operations, education, and training. It provides military guidance for use by the Armed Forces in preparing their appropriate plans. It is not the intent of this publication to restrict the authority of the JFC from organizing the force and executing the mission in a manner the JFC deems most appropriate to ensure unity of effort in the accomplishment of the overall objective.”
