“The Department of Defense raised the level of security conditions at U.S. military bases Thursday night, May 7, 2015, to ‘Bravo’ because of the growing concern of terrorist threats in the United States.
But what does the Bravo level specifically mean?
The Force Protection Condition, or FPCON, is a five-tier threat level system that is overseen and decided by the Department of Defense. It has various levels that show security concern in the country. According to the list, the antiterrorism program ‘provides guidance and establishes standards for implementing the levels’ in the Department of Defense. Local commanders decide which level is appropriate.”
