What is the condition described by "sunrise"?

The condition described by "sunrise" refers to the availability of command and control (C2) sensors. The term "sunrise" in this context signifies a specific operational phase when the sensor systems are fully functional and active. This typically aligns with times of enhanced visibility or operational readiness, which is why the correct response indicates that C2 sensors are available.

In military operations, the availability of these sensors is critical for gathering actionable intelligence and maintaining situational awareness. During this phase, units can efficiently monitor their surroundings, support operations, and make informed decisions based on the real-time data provided by the sensors. Understanding this concept is crucial for recognizing how different conditions impact operational readiness and effectiveness within a command and control framework.
