How would you locate an active marine?

To locate an active marine, you can use a combination of methods including radar, sonar, and satellite tracking systems to monitor their positions. Additionally, communication with the marine unit and using AIS (Automatic Identification System) can provide real-time data on their movements. Engaging with local maritime authorities or utilizing marine traffic websites can also help in tracking active operations. Finally, visual observation from vessels or aircraft can supplement these technologies to confirm their location.
