The MEDEVAC 9-LINER REQUEST is a military term, an emergency notification form to help alert and dispatch paramedics or emergency personnel in an orderly manner, even in stressful and sometimes hectic situations. It helps to ensure that needed information is communicated clearly and in a standardised way, and that help gets to where it is actually needed.
The 5 W´s are hardly usable in military, therefore two schemes are in use in parallel:
The METHANE scheme: (we will explain in more detail in another blog-post !)
M = military details
E = exact location
T = time & type of inicent
H = hazards in the area
A = approach routes
N = number of casualties
E = expected response
as well as the MEDEVAC 9-LINER REQUEST, whose origins probably go back to the Vietnam conflict and which counts as a fixed training component for non-commissioned officers in the US Army of all troops (Warrior Leader Skills).
The MEDEVAC 9-LINER is an absolute added value even outside of military service. It is indispensable for first responders, executives or employees in the security sector.
The greatest challenge is the GRID determination - the exact location determination
In fact, any soldier, first responder, executive or security guard MUST be able to perform this skill blindly. From my own experience, I maintain that this is purely a matter of practice. Once understood, it should be memorised forever. Further information on this will be covered in a separate blog post soon.
Communication in multinational operations is not exclusively but frequently conducted in English, so it can be an additional challenge for many soldiers. Sending an appropriate emergency message, also in English, therefore requires training and, above all, practical exercises within the force, such as during mission preparation.
In addition, it should be ensured that English-speaking personnel are present at the handover point.
When the emergency report is sent, it should be set down in writing in and transmitted to the tried and testet recipe "think - press - speak" at radio, phone or other means of guidance (e.g. Roshan) commonly used in field.
The MEDEVAC emergency notification is based on availability for ground-based as well as air rescue resources.
In areas of war or crisis, the latent danger of possible minefields must also be considered. These are usually marked on military maps, but this is no guarantee. An emergency report of e.g. a crashed transport vehicle close to a "known minefield" should only be cleared up very carefully in order to pass on the most necessary information. In this case, no immediate first aid measures are taken, but rather waiting for reinforcements with equipment intended for this purpose or for further orders.

Correct call of the MEDEVAC 9-LINER REQUEST:
There are different versions for sending the emergency message. Basically, it is important to transport information as quickly as possible. I would like to give you two examples. Depending on the mission, find out in advance which one is required in case of emergency. Try to send the MEDEVAC 9-LINER REQUEST in a way that is easy to understand and also includes pauses in speech (_). The first 5 lines (Line1-5) should be transmitted within 25 seconds, as they contain the most important emergency information. Lines 6-9 can also be transmitted only when the rescue forces are already on their way, in order not to interrupt the radio traffic for too long.
Most of the time, however, the Medevac 9 liner is sent completely without interruption.

_ = break in speaking

The MIST-REPORT is a very simple report format that contains medical details and thus supplements the MEDEVAC 9-LINER REQUEST with valuable information.
M = Mechanism A simple description of the mechanism of injury.
I = Injuries Often combined with the mechanism, i.e., gunshot wound to the leg...
S = Sign/Symptoms Massive haemorrhage, not following commands, no radial pulse.
T = TreatmentWhat was done for the casualty to fix the above-noted issues?
Case Exemple MIST REPORT:
»Person male, adult with a gunshot wound on the right thigh, critical bleeding, tourniquet applied and bleeding stopped, consciousness impaired and no radial pulse felt- carotid pulse at 130.«
Even if you may not be able to do much with the form as a private person it should still be a food for thought, perhaps something to think about on your next hike or adventure: correctly requesting location determination & help!
The MEDEVAC 9-LINER REQUEST methodology ensures that the wounded receive the correct medical care quickly, and thus possibly save lives.
