Which of the following terms refers to a system for a high-security intelligence community?

The term that refers to a system for a high-security intelligence community is JWICS, which stands for Joint Worldwide Intelligence Communications System. This system is designed to allow secure communication and data transfer among members of the intelligence community, ensuring that sensitive information is protected against unauthorized access. JWICS facilitates the sharing of classified information, essential for intelligence operations and national security.

The other options refer to different concepts. JIT (Just In Time) typically relates to inventory management and manufacturing processes, not intelligence systems. JTTF (Joint Terrorism Task Force) is a collaboration between different law enforcement agencies to prevent and respond to terrorism, rather than a communication system. JRE (Joint Reception Element) refers to a logistical concept used in military operations, dealing with planning and distribution of resources rather than an intelligence communication system. Thus, JWICS is specifically associated with secure communication within the intelligence community, making it the correct answer.
