An active shooter incident that occurs at a naval dock supporting the launch of tube ships would pose a significant risk factor to which of the following?

In the context of an active shooter incident at a naval dock, the most significant risk factor is system disruption. This is because such an incident can lead to immediate interruptions in operations, affecting critical systems involved in the launch and management of tube ships.

An active shooter event can compromise safety and security protocols, leading to lockdowns, evacuations, and a halt in normal activities. The operational systems that handle logistics, management, and coordination at the dock would be disrupted, thereby affecting the overall efficiency and functionality of naval operations. The potential for loss of life and the ensuing chaos can result in significant delays and an inability to resume normal operations quickly.

While other areas like communications systems and logistics operations may also feel the impact of such an incident, the overarching theme is that the incident fundamentally disrupts the entirety of systems in place to support the naval dock's primary mission. Therefore, system disruption captures the essence of the risk posed by the active shooter scenario most effectively.
