Answer:
National Response Coordination Center
Step-by-step explanation:
The support elements of the national response capabilities will be directly involved in the field during emergency situation. (such as providing medical help for the victim, getting rid of debris after incident, finding out missing people, etc)
Even though the national response coordination center involved in the operation, it only act as a management center for other agencies and monitoring the whole operation from the base. They are not directly involved in the field.
