What information is included in Line 2 of the 9-Line?

Line 2 of the 9-Line is designed to provide essential communication details that facilitate effective coordination during medical evacuation (MEDEVAC) operations. This line specifically contains the radio frequency, call sign, and suffix that will be used for the communication between the units involved in the operation. Having this information readily available ensures that all parties can communicate effectively and promptly, which is crucial in a time-sensitive situation like a medical evacuation.

This specific detail allows the aircraft and the ground unit to establish a clear line of communication, ensuring that instructions and further information can be shared rapidly, ultimately leading to a more efficient and organized response during emergencies. Therefore, the correct answer is directly related to the operational capabilities needed to conduct a successful MEDEVAC.
