What does the FPCON system specifically aim to address?

The FPCON (Force Protection Condition) system is specifically designed to address terrorist threats to military personnel, installations, and resources. It establishes a series of graduated security measures that are implemented based on the level of threat assessed. This system allows commanders to effectively manage responsiveness to potential terrorist activities and ensure the safety and security of the force. Each FPCON level—ranging from normal to critical—reflects the severity and immediacy of the threat, guiding the appropriate security response and resource allocation. This focus on mitigating the risks posed by terrorism is what makes this answer correct.
