MEDEVAC 9-LINE REQUEST

3 min (prepare) 25 sec (lines 1-5) 1 min (lines 6-9)

Conditions: You have been directed to request MEDEVAC for a wounded teammate. Wartime, non-CBRNE environment.

Understanding This Task

The 9-line MEDEVAC is a standardized radio request for medical evacuation. Lines 1-5 are transmitted first on the MEDEVAC frequency (urgent info the aircraft needs). Lines 6-9 go on the operational frequency after switching.

You must derive information from the TCCC cards, SOI, and map — nothing is given to you. No cheat sheets or GTAs during testing.

100% accuracy with proper brevity codes and RTO pronunciation. Say "Break" between categories and "Over" to end.

Common NO-GO Mistakes

  • 100% accuracy required — any wrong brevity code = NO-GO
  • Not deriving info from TCCC cards (it must not be given to you)
  • Forgetting to switch to operational frequency for lines 6-9
  • Not saying "Break" between categories or "Over" at end
  • No cheat sheets or GTAs allowed during testing

Starting Configuration

Equipment: Protractor, military map with location plotted, SOI, two operational radios, two TCCC cards, signaling devices, laminated paper with alcohol pens.

Radio: Set to operational frequency — candidate must change to MEDEVAC frequency from SOI.

Task Basis: 081-COM-0101

Preparation Timer: 3 Minutes
3:00
Critical Notes
  • 100% accuracy required with proper brevity codes and RTO procedures.
  • Candidate must derive information from TCCC cards — not have it given to them.
  • Must switch radio to operational frequency for lines 6-9.

PERFORMANCE MEASURES

0/3 GO
  1. 1

    Prepare the MEDEVAC request

    • Determine grid coordinates: complete 6-digit grid with grid zone identifier, accurate within 200 meters.
    • Determine operational radio frequency, call sign, and suffix from SOI.
    • Determine number of patients and precedence from TCCC cards.
    • Determine special equipment required based on site, injuries, and guidance.
    • Determine number and type of patients (litter/ambulatory) from TCCC cards.
    • Determine security of pickup site (given by grader).
    • Determine method of marking pickup site (select from available devices).
    • Determine patient nationality and status from TCCC cards.
  2. 2

    Transmit lines 1-5 (within 25 seconds) CRITICAL

    • State: "I have a MEDEVAC request." (Grader responds within 3 seconds.)
    • Line 1: Six-digit grid with grid zone identifier.
    • Line 2: Operational frequency, call sign, and suffix.
    • Line 3: Patients by precedence — A=Urgent, B=Urgent-Surgical, C=Priority, D=Routine, E=Convenience. Say "Break" between categories.
    • Line 4: Special equipment — A=None, B=Hoist, C=Extrication, D=Ventilator.
    • Line 5: Patients by type — L=Litter, A=Ambulatory. Say "Break" between categories. End with "Over."
  3. 3

    Transmit lines 6-9 (within 1 additional minute)

    • Switch radio to operational frequency. Regain contact with evacuation platform.
    • Line 6: Security — N=No enemy, P=Possibly, E=Enemy, X=Enemy (armed escort required).
    • Line 7: Marking — A=Panels, B=Pyrotechnic, C=Smoke, D=None, E=Other.
    • Line 8: Nationality/Status — A=US Military, B=US Citizen, C=Non-US Military, D=Non-US Citizen, E=EPW.
    • Line 9: Terrain description. End with "Over."

Supplementary context — not tested directly, but builds deeper understanding.

9-Line MEDEVAC Breakdown (Table B-1): The Ranger Handbook provides a detailed explanation of each line, including who provides the information, where it comes from, and why it is needed:

Line Item Source / Key Detail
1Location of pickup site6-digit MGRS grid from map/GPS. Include grid zone letters to prevent confusion.
2Radio frequency, call sign, suffixFrom SOI/ANCD. Must be the frequency at the pickup site, not a relay frequency.
3Patients by precedenceFrom patient evaluation. Assists in prioritizing missions. "Break" between categories.
4Special equipmentPlaced onboard before mission starts (None / Hoist / Extraction / Ventilator).
5Patients by typeLitter (L) vs. Ambulatory (A). Determines number and configuration of vehicles dispatched.
6Security of pickup siteN/P/E/X. Guides crew in assessing approach and whether armed escort is needed.
7Marking methodDo NOT transmit color until aircraft contacts you. Crew identifies color, you verify.
8Nationality and statusPlans destination facilities and need for guards. English-speaking rep at pickup site.
9CBRN contamination (wartime) / Terrain description (peacetime)Helps plan the mission: which vehicle, when, and route to landing site.

MIST Report: Sent after the 9-line request — Mechanism of injury, Injuries sustained, Signs/symptoms, Treatment given. Do NOT delay the MEDEVAC waiting for MIST information (Ch. 15, para 15-22).
