Final answer:
When capture is imminent, one should sanitize personal or sensitive materials, leave evidence of presence at the capture point, and communicate the situation. All the options are true in the given condition.
Step-by-step explanation:
When capture is imminent, several actions should be taken to maintain operational security and personal safety. These include sanitizing personal or sensitive materials to ensure that no sensitive information falls into the wrong hands. Leaving evidence of presence at the capture point may assist in your eventual tracking and recovery by friendly forces.
It is also advised to communicate your situation, if possible, to inform your chain of command or support network about the capture. While retaining a personal cell phone could be beneficial for communication, it presents a significant risk as it can be used to track and spy on you, necessitating careful consideration.
It is crucial to understand that these actions are situationally dependent, and the right decision can vary based on the environment and the resources available at the time of capture.
