Which method is commonly used to gather information on missiles?

The method most commonly used to gather information on missiles is through Combat Information Center (CIC) operations. CIC serves as the nerve center for processing and disseminating tactical data in naval operations. This environment allows for real-time analysis and decision-making based on incoming data regarding enemy activities, including missile launches.

CIC operations utilize a variety of sensors and technology to monitor missile trajectories, launch locations, and potential threats, integrating this information with tactical assessments. This sophisticated approach ensures that commanders have access to accurate and timely data, which is critical for mission success and the safety of naval forces.

The other methods listed have their uses but do not provide the comprehensive and integrated approach that CIC operations offer for missile information gathering. Manual measurement lacks the speed and accuracy facilitated by modern systems; visual spotting techniques depend heavily on line of sight and can be unreliable over long distances or in adverse conditions; and geographical mapping is useful for terrain analysis but does not directly yield real-time information about missile activity.
