In a 9-line medevac, which lines change during peace time?

• A. Lines 6 and 9
• B. Lines 4 and 5
• C. Lines 1 and 2
• D. Lines 7 and 8

Answer: (A)

Understanding which parts of the nine-line MEDEVAC message are adjusted for peacetime helps crews communicate quickly and safely. The lines that change are the ones that convey security at the pickup site and NBC (chemical, biological, radiological, or nuclear) contamination status. In peacetime, you’ll typically indicate that the pickup site is secure and that there is no NBC contamination, so those lines are updated to reflect those conditions. The other lines—location details, radio frequency and call sign, patient numbers and types, any special equipment, patient priority, method of marking the site, and patient nationality/status—contain information that remains consistent for the mission itself and doesn’t hinge on peacetime versus wartime status.
