What is the primary purpose of a 9-line medevac request?
To submit supply resupply requirements
To coordinate artillery fire missions
To call for close air support
To request medical evacuation using a standardized format
The 9-line medevac request is a standardized format used by U.S. and allied forces to request medical evacuation assets. It ensures artillery, aviation, and medical personnel understand the situation rapidly. The structured lines convey location, patient information, and special equipment requirements.
Which line in the 9-line medevac request indicates the grid coordinates of the pickup site?
Line 3
Line 2
Line 4
Line 1
Line 2 of the 9-line medevac request specifies the grid coordinates for the pickup site so that evacuation assets can navigate there precisely. This is typically given in a six-digit grid format. Accurate grid information is critical for fast and safe patient pickup.
What information is required in Line 3 of a medevac request?
Nationality and status
Special equipment required
Number and type of patients
Security at pickup site
Line 3 of the 9-line medevac request asks for the number and type of patients, usually broken down into ambulatory and litter patients. This allows medical teams to prepare the proper transport means and medical supplies. Maintaining clarity in patient count supports resource allocation.
Which line specifies the special equipment required for the evacuation?
Line 5
Line 7
Line 6
Line 4
Line 6 of the 9-line medevac request indicates any special equipment needed such as hoist, extraction devices, or ventilator-equipped helicopters. This ensures evacuation assets arrive configured correctly. Clear specification of requirements increases mission success.
What does Line 1 of the medevac request indicate?
Radio frequency, call sign, and suffix
Number of casualties
Grid coordinates
Security level
Line 1 of the medevac request contains the radio frequency, call sign, and suffix used for communications. This information is vital to coordinate with evacuation assets and confirm mission details. Proper use of communications ensures clear, secure exchanges.
What format is typically used for the grid coordinates in Line 2?
Universal Transverse Mercator (UTM)
Latitude/Longitude in degrees
Decimal degree format
Six-digit Military Grid Reference System (MGRS)
The Military Grid Reference System (MGRS) six-digit format is the standard for 9-line coordinates. It offers precision to within 100 meters, which is sufficient for medevac pickups. Other formats are less common in tactical operations.
Which line directs how the pickup site is marked for the incoming aircraft?
Line 7
Line 5
Line 9
Line 8
Line 7 of the 9-line medevac request specifies how the pickup site is marked, such as panels, smoke, or pyrotechnics. This ensures pilots can visually identify the correct landing zone. Proper marking reduces confusion and enhances safety.
Which line provides information about enemy, friendly, or unknown threats in the area?
Line 8
Line 6
Line 4
Line 5
Line 5 of the 9-line medevac request indicates pickup site security, specifying whether it's secure, enemy-controlled, or under unknown threat. Codes like "P" (picked up by friendly forces) and "E" (enemy) are used. This information helps aircraft crews prepare for landing risks.
How should you transmit the time in Line 4 for a combat medevac?
Local time with AM/PM
24-hour Zulu time
GPS Week and seconds
Weekday and local hour
Line 4 requires the pickup time using 24-hour Zulu (UTC) format. This standardization avoids confusion across time zones and daylight savings changes. Using Zulu ensures synchronization among multinational forces.
If requesting a helicopter equipped with a hoist, how is this indicated in the 9-line?
Transmit a separate hoist request message
Add 'Hoist' to the remarks in Line 9
Include 'Hoist' in Line 5
Specify 'Hoist' in Line 6
Special equipment requests, such as a hoist, are specified in Line 6. The medical evacuation platform will arrive configured to meet that requirement. Omitting it can force a second mission or lead to mission abort.
Which line would you use to report contamination from chemical, biological, radiological, or nuclear (CBRN) threat?
Line 7
Line 9
Line 5
Line 3
Line 9 contains 'NBC/radiation' information to alert crews about any chemical, biological, radiological, or nuclear hazards at the pickup site. This ensures aircraft and personnel are prepared with protective gear. It's essential for mission safety.
How are litter versus ambulatory patients distinguished in Line 3?
Litter over ambulatory in 'L/A' format
Ambulatory over litter in 'A/B' format
Use separate medevac requests
Total combined patient count only
Line 3 uses an 'A/B' format to list ambulatory ('A') patients first, then litter ('B') patients. For example, '2/4' indicates two ambulatory and four litter patients. This distinction informs aircraft loading and medical crew readiness.
What code in Line 5 indicates the pickup site is under enemy fire?
U
X
P
E
In Line 5, the code 'E' signifies the pickup site is under enemy fire or enemy-controlled. 'P' denotes pickup by friendly forces, while 'U' means unknown threat. Correct threat classification is vital for aircrew risk assessment.
Which line contains information about patient nationality and status?
Line 4
Line 7
Line 6
Line 8
Line 8 of the 9-line medevac request indicates the patient's nationality and status, such as U.S. military, other military, civilian, or enemy prisoner of war. This helps prioritize care and comply with legal requirements.
Which detail must be included in Line 2 to ensure accuracy of the pickup location?
Six-digit grid coordinate
GPS decimal minutes
Street address of site
Elevation of the landing zone
A six-digit grid coordinate in MGRS is required in Line 2 for precise location identification, giving accuracy to within 100 meters. This level of precision is critical in tactical environments. Alternatives like street addresses are not used in combat scenarios.
How should the medevac requester indicate 'no enemy troops' at the pickup site?
Add 'Zero Enemy' in Line 7
Omit Line 5 entirely
Use code 'N' in Line 5
Transmit 'NONE' in Line 4 remarks
In Line 5, the code 'N' denotes 'no enemy troops present' at the pickup site. Standardized single-letter codes ensure brevity and clarity under pressure. Omitting the line or using nonstandard terms can cause misinterpretation.
When providing grid coordinates with elevation, how is altitude expressed?
No altitude is ever used
In hundreds of feet prefixed by 'H'
In feet with 'FT' suffix after the grid
In meters separated by a slash after the grid
When altitude is included, it's placed after the grid coordinate separated by a slash and expressed in meters. For example, '123456/50' indicates a 50-meter elevation. This aids pilots in assessing approach and rotor clearance.
In a multiple incident scenario, how is the 9-line amended for a second pickup site?
Include 'Secondary' prefix on Line 1 only
Add lines 10 - 18 to the same request
Send a new 9-line with incremented suffix
Use a different message format entirely
For additional pickup sites, the requester sends a separate 9-line message with the same call sign and a new suffix (e.g., 'A', 'B'). This avoids confusion by keeping each evacuation request self-contained. Extending beyond nine lines is nonstandard.
What medical precedence code denotes a patient requiring immediate, life-saving surgery?
Urgent
Routine
Convenience
Priority
'Urgent' medical precedence indicates the casualty needs immediate, life-saving surgery within two hours to avoid death or serious disability. It's used in Line 4 after the pickup time if precedence is requested. Accurate precedence ensures proper aircraft availability.
Which line would be used to specify the number of litters and ambulatory patients separately when no patients are present?
Use 'Z' in Line 5 to indicate zero
Type '0/0' in Line 3
Place 'None' in Line 2
Leave Line 3 blank and note in Line 9
If there are no patients, Line 3 should read '0/0' to denote zero ambulatory and zero litter patients. This confirms the request was still processed but found no casualties. Clarity prevents misunderstanding and unnecessary allocation of resources.
What is the required format for using a grid zone designator when transmitting coordinates in Line 2?
Include the full MGRS grid zone prefix
Only the six-digit easting and northing
Latitude first then longitude
Use only the map sheet name
The full MGRS grid zone designator (e.g., '14S NU 123456') must precede the six-digit coordinate in Line 2 so the location is unambiguous. Omitting the zone can lead to misrouted pickups. Standardization ensures mutual understanding.
In the event of aircrew injury during a medevac, what additional line is transmitted to request replacement crew support?
Flag 'X-Crew' in Line 6 and maintain same message
Update Line 1 with new call sign only
Transmit an additional support request using nine-line format with suffix 'C'
Send a separate 9-line with 'Crew Replacement' in Line 9
When aircrew are injured, a new 9-line request with a unique suffix (e.g., 'C') is sent to request replacement crew support. The suffix differentiates the new mission from the casualty evacuation. Using the nine-line ensures all necessary data is communicated.
How should weather conditions affecting the pickup site be communicated in a 9-line medevac request?
Adjust Line 2 grid to account for drift
No standard method; rely on prior briefing
Transmit weather on separate frequency
Include 'WX' remarks in Line 9
Weather remarks (e.g., 'WX: 300ft ceiling, 2SM visibility') are included in Line 9. This informs aircrews of conditions that might affect flight safety or landing. Line 9 serves as the catch-all for remarks not covered by lines 1 - 8.

Cheat Sheet

  1. Grid Coordinates and Format (Line 1) -

    Line 1 requires the precise MGRS or UTM grid location for pick-up, such as "31U FS 07941 48341." Using the "Grid-Get-There" mnemonic helps you recall to confirm zone, grid, easting, and northing. According to U.S. Army FM 8-10-6 and NATO STANAG 3204, accurate coordinates prevent delays in medevac response.

  2. Pick-Up Site Security (Line 2) -

    Line 2 identifies security at the landing zone by stating "P" for possible, "E" for enemy, or "F" for friend. An example of 9 line medevac best practice is scanning for threats and communicating "P" if unknown, as outlined in official Army medevac manuals. This step ensures crews can take proper force protection measures before approach.

  3. Patient Numbers and Precedence (Lines 3 & 5) -

    Lines 3 and 5 report total patients by litter (e.g., 2L) and ambulatory status (e.g., 3A), alongside precedence categories: Urgent, Urgent Surgical, Priority, Routine, and Convenience. The "upric" mnemonic (Urgent, Priority, Routine, Immediate, Convenience) aids memory, as detailed in academic journals on combat casualty care. Mastering these categories in an example 9 line medevac scenario refines your triage and reporting speed.

  4. Special Equipment and Marking Method (Lines 4 & 7) -

    Line 4 specifies hoist, ventilator, or extraction devices, while Line 7 covers LZ marking method - panels, smoke color (VS-17), or electronic beacons. A sample formula "HS-BSM" (Hoist/Scoop, Beacon/Smoke, Panels) helps recall equipment versus marking requirements, referenced in the NATO Casualty Evac deeper dive. Clear marking reduces approach errors under fire.

  5. Additional Info: Nationality, Security & NBC (Lines 8 & 9) -

    Line 8 indicates patient nationality and status (e.g., U.S. military vs. civilian), and Line 9 addresses NBC contamination or terrain/weather comments. The "SNOW" mnemonic (Status, Nationality, NBC, Weather) keeps these critical details top of mind, per Army medical research. Including these in your 9 nine line medevac report enhances situational awareness and safety.
