Royal Army College

Lesson Overview

Before any technique, a first-aider needs to know what they are for. This lesson sets the foundation of the whole course: why every soldier is a first responder, the duty of care that places on them, the principle that care is owed to everyone who needs it, and the simple aims that guide every action at a casualty's side.

It also teaches the first actions that begin every case, before any bleeding is packed or any airway opened: making sure the scene is safe enough to work, getting a quick sense of how bad the casualty is, and getting help moving early. These are the same whatever the injury, and they are the part of first aid most often done badly under stress. Everything in Lessons 02 to 10 hangs off this opening drill.

A word at the outset, the same word that opens every lesson in this course. This is the knowledge layer. The hands-on skills, opening an airway, packing a wound, fitting a tourniquet, carrying a casualty, are built on the ground with a trained instructor watching your hands, and certified in person. Nothing here is a skill to first attempt on a real casualty from reading alone. Learn what a first responder is, where to start, and where to stop.

By the end you will be able to explain why the Army trains every member in first aid, state the aims and limits of first aid, explain why care is owed to friend, civilian, and former enemy alike, describe why the first few minutes matter so much, and carry out the first actions at any casualty: check for danger, check the casualty's response, shout for help, and begin the quick check for life threats.

Key Terms

First aid: the immediate care given to an ill or injured person before professional medical help is available or while it is on its way.
First responder: the first trained person to reach a casualty. In the field, that is usually a soldier.
Buddy aid: the first aid one soldier gives another, or gives any casualty, using personal and team kit and basic trained skills, in the minutes before a medic or higher care arrives. It is what this whole course teaches, and it has firm limits.
Duty of care: the responsibility to take reasonable steps to protect the safety and welfare of others.
Casualty: any person who is ill or injured and in need of care.
Scene safety: the deliberate check for continuing danger to you, the casualty, and bystanders, made before you approach, so that you do not add a second casualty to the first.
Primary survey: the rapid, ordered first check that finds and treats the immediate threats to life. Introduced here, taught in full in Lesson 02.
Chain of survival: the linked sequence of actions, from the first person on the scene to definitive hospital care, that together give a casualty the best chance of living. A chain is only as strong as its weakest link, and the first link is you.
Consent: the casualty's permission to be helped. A conscious casualty may accept or refuse care; an unconscious one is treated under the assumption that a reasonable person would want help.
Triage: sorting casualties by the urgency of their need when there are more casualties than carers (Lesson 08).

Why every soldier is a first responder

The Army does not have a doctor at every soldier's elbow. It has soldiers. When a person is badly hurt, on operations, in training, at a road crash, in a flood, or on a freezing night, the help that arrives first is almost always a soldier with a first-aid kit and the training to use it. By the time professional medical help reaches the scene, the most important minutes may already have passed.

So the Army trains every member, of every rank and trade, to a common standard of first aid. This is not a specialist skill held by a few. It is a basic skill of soldiering, like weapon handling and fieldcraft, and for the same reason: lives depend on every soldier being able to do it. A unit in which only the medic can save a life is a unit in which most casualties will not be reached in time.

There is a plainer way to see why this falls to the ordinary soldier. The Royal Kaharagian Army is a small, lightly armed force whose work is as often humanitarian as military: helping after a storm, on a flooded road, on a cold welfare patrol among people in need. The soldier is frequently the only trained first-aider for some distance, and the casualty is as likely to be a civilian or a stranger as a comrade. The medic, where there is one, cannot be everywhere. The maths of distance and time leaves no one else to do it. That is you.

The chain of survival and the chain of care

No first-aider saves a life alone. A seriously injured casualty is carried from the point of injury to hospital by a chain of people and actions, each handing on to the next, and their chances depend on every link holding. Picture the whole chain before learning any single part, because it shows where you sit and why your link matters.

   POINT OF INJURY                                          DEFINITIVE CARE
        |                                                          |
        v                                                          v

   +----------+   +-----------+   +-----------+   +-----------+   +---------+

   "A chain is only as strong as its weakest link.
    The first link is the soldier who is there."

Two ideas are folded into this picture. The first is the chain of survival: the linked actions that, taken together and in time, give a casualty the best chance of living, from early action at the scene, to early help summoned, to the right first aid, to a clean handover, to definitive care. Drop or delay any one link and the chain weakens, however strong the others. A brilliant surgeon cannot save a casualty who bled out at the roadside because no one stopped the bleeding; an excellent first-aider cannot save one whose call for help never went out. Your job is not only to do your own link well, but to keep the next link moving while you work, which is why help is called early.

The second is the chain of care from the point of injury onward: the same casualty passing through hands of rising skill, from you, to a medic if one is near, to whatever evacuation the situation allows, to a doctor and a hospital. Each set of hands does what its training allows and hands on, keeping the casualty alive and the story whole. This is why the report you give at handover matters as much as the care you gave (Lesson 07 teaches it in full), and why getting and keeping help coming is itself a first-aid skill. You are not expected to fix everything, only to hold your link and feed the casualty cleanly into the next.

Scene safety: the first action of all

The first thing you do at any casualty is not to the casualty. It is a deliberate look at the scene, made before you move in. This single habit prevents more harm than almost any treatment, and skipping it is the commonest way a willing rescuer turns one casualty into two.

The rule is blunt: you are no use as a second casualty. A rescuer who runs to a fallen comrade in the open and is shot, or steps into water to reach a drowning person and drowns, or touches a casualty still in contact with live electricity, has not helped. They have doubled the problem and removed the one person who could have solved it. Courage in first aid is not rushing in; it is the discipline to stop for the two or three seconds it takes to ask what put this person down, and whether it can put you down too.

So before you approach, you stop and assess, in this order:

   STOP AND ASSESS  (a two- to three-second pause, made on approach)
   ----------------------------------------------------------------
   1. DANGER TO ME           fire, fumes, electricity, traffic, water,
                             falling debris, unstable ground, violence
   2. DANGER TO THE CASUALTY will the place harm them further if they
                             stay? do they need moving to safety?
   3. DANGER TO BYSTANDERS   are others walking into the same hazard?
                             warn them; control the scene

Having found the danger, you deal with it before you treat, by one of three means. Remove the danger where you safely can: switch off the power, stop the traffic, put out the small fire. Remove the casualty from the danger where you cannot: a short, deliberate drag clear of the road or the water, accepting that moving a casualty has its own risks, which Lesson 07 covers. Or, where the danger is one you cannot beat, do not enter: get those who can, the fire service, the rescue boat, the power company, while you control the scene and keep help coming. Under hostile fire the very first medical act may be to win the firefight, take cover, or use smoke, because no first aid is possible in the open under effective fire. Lesson 02 carries scene safety further into the working drill; here it is enough that it comes first, every time, and is an act of judgement, not of fear.

One more habit belongs to this first step: protect yourself from the casualty's blood and body fluids. Put on gloves from your kit, and use eye protection where it is issued. This is not squeamishness; it keeps the rescuer fit to go on rescuing, and it takes only seconds when the gloves are where they should be.

The first actions: danger, response, shout, primary survey

Scene safety opens a short, fixed sequence of first actions that begins every case, before you reach for any dressing. It is the spine the rest of the course hangs off, and a first-aider who knows the first four moves cold does not freeze. The sequence is Danger, Response, Shout for help, then the Primary survey.

   DANGER ........ Scene safe? Deal with danger before you treat.
      |
      v
   RESPONSE ...... Speak and touch: "Can you hear me? Open your eyes."
      |
      +-- responds ----> conscious: reassure, ask what happened, begin checks
      |
      +-- no response -> SHOUT FOR HELP: call out; send a bystander for the
      |                  medic/ambulance; if alone, do not leave them yet
      v
   PRIMARY SURVEY  The quick, ordered hunt for life threats. Taught in full
                   in Lesson 02 as MARCH: Massive bleeding, Airway,
                   Respiration, Circulation, Hypothermia and the head.

Take the moves one at a time.

Danger you have already met: the scene-safety check, made on approach. It is the first move because everything after it depends on the scene being safe enough to work in.

Response is how you learn, in a few seconds, roughly how ill the casualty is. Kneel by them, speak clearly, and gently touch or shake the shoulders: "Can you hear me? Open your eyes. Squeeze my hand." A casualty who answers, opens their eyes, or obeys is conscious, and their airway is, for the moment, working. One who makes only a groan, moves only when you press hard, or does not react at all is seriously ill until proved otherwise, and their airway is the next thing you must protect. You need only the gross answer here, does this person respond or not; Lesson 02 teaches the AVPU scale (Alert, responds to Voice, responds to Pain, Unresponsive) for recording it precisely.

Shout for help keeps the next link of the chain moving while you work. The instant you see a serious casualty, raise the alarm. If others are near, point a specific person to the task ("you, in the green jacket, call an ambulance and come back and tell me you have done it"), because a task given to a named person gets done, while one shouted to a crowd gets done by no one. If you are alone with an unresponsive casualty, you still call out, but do not yet abandon them to go for help; you open the airway and check breathing first (the primary survey, next), because a blocked airway will kill in the time it takes to run for a phone. Exactly who to call and what to pass comes in the next section.

The primary survey is the quick, ordered hunt for what is killing the casualty in the next few minutes, treating each threat the instant you find it before moving to the next. This is the heart of the course, and Lesson 02 teaches it in full as the MARCH drill: Massive bleeding controlled first, because heavy limb bleeding can drain a casualty in two to three minutes; then the Airway, opened and kept open, because a blocked airway kills faster still; then Respiration, breathing; then Circulation, hidden bleeding, and shock; then Hypothermia and the head. You do not need the detail yet, only the knowledge that after Danger, Response, and Shout there is a fixed, fast check that always puts the quickest killers first, so that under pressure you follow the order rather than invent it. Lessons 03 to 06 teach each treatment the survey calls for, one at a time.

Learn these four moves until they are automatic. The value of a fixed drill is that it runs when you are frightened, and the moment you need it most is the moment you will be least able to think it up from scratch.

Calling for and summoning help: getting and keeping help coming

Early help deserves its own treatment, because the call is a first-aid skill in its own right and a poor one wastes the very minutes the chain of survival depends on. The aim is easy to state and easy to get wrong: get help moving as early as you can, give it what it needs to reach you and come prepared, and keep it coming until it arrives.

Call, or send someone to call, the moment you grasp that the casualty is seriously hurt, not after you have finished treating, because help summoned late arrives late. If you can treat and call at once, do both; if you must choose, control catastrophic bleeding and protect the airway first, because those are what kill in the time the call would take. Where others are present, delegate the call to a named person and have them report back that it is done, so that you know help is genuinely on its way and not still waiting in a confused bystander's hand.

Pass the message in a clear, fixed order, so nothing important is left out under stress:

   THE CALL FOR HELP  (say it in this order; keep it short and clear)
   ----------------------------------------------------------------
   WHERE     Where you are, as exactly as you can: a grid reference,
             a road and a landmark, a building, a track junction.
             This is the single most important item: help that does
             not know where to come, cannot come.
   WHAT       What has happened: the kind of incident (a fall, a blast,
             a road crash, a near-drowning), so help arrives prepared.
   HOW MANY   How many casualties, and how badly hurt each one is, so
             the right amount and right kind of help is sent.
   WHAT NEEDED What you need: an ambulance, the rescue boat, the fire
             service, a medic, more hands, specific equipment.
   WHO / CALL  Who you are and a number or means to call you back, then
             confirm the message was understood before you ring off.

Note the order of priority. Where comes first and is repeated if there is any doubt, because every other detail is useless if help cannot find the casualty; it is the one thing you must get across even if the line drops after a sentence. Then enough of what and how many for the right help to be sent in the right strength. In RKA work the message often goes by radio, and the Signals training teaches the formal casualty report and the net procedure; the principle is the same on any means, and Lesson 07 ties the call into the wider handover and evacuation. The last discipline is to keep help coming: if the situation worsens, if more casualties appear, or if your first call may not have got through, send an update or call again. One message sent is not help guaranteed to arrive.

Consent and the duty of care: acting in the casualty's best interest

You may not simply seize hold of a stranger, even to help. First aid is care offered to a person, and a person has a say in what is done to their own body. Handled well this is a matter of a few words; handled badly it can frighten a casualty or overstep a line you should not cross.

With a conscious casualty, you ask. Tell them who you are and that you are first-aid trained, and ask if you may help: "My name is __. I am first-aid trained. May I help you?" This is consent, the casualty's permission to be helped, and a conscious adult who understands their situation may give it or refuse it. Most accept gladly, and the asking itself reassures them. If a casualty refuses, you do not force care on them; you stay with them if you safely can, keep offering, make sure help is still coming, and watch in case they lose consciousness, at which point the rule below changes. Talk to them throughout and explain what you are about to do before you do it.

With an unconscious casualty, or one too badly hurt or confused to understand and answer, you cannot ask, and you do not wait. You act under the long-standing principle that a reasonable person, in the same emergency, would want to be helped, so consent is assumed. You give the care you are trained to give, in the casualty's best interest. Duty of care and assumed consent meet here: you are not only permitted to act, you are expected to, because to stand back from an unconscious, dying casualty you could help, within your training, would itself fail the duty.

Two courtesies belong to this duty. Treat the casualty's dignity as part of their care: uncover only what you must, cover them again, shield them from onlookers, and speak of and to them as you would wish to be spoken of. And carry the same respect to the bodies of the dead, handled with care and not exposed or made a spectacle.

The duty of care

With the training comes a duty. A member who can give life-saving care, and who is present when it is needed, is expected to give it, within the limits of their training and the safety of the situation. This duty is owed to comrades, but it does not stop there.

The duty has a hard edge worth stating plainly: you act, within your training, even when it is frightening, messy, or inconvenient, because a person's life is in the balance and you are the one who is there. It also has a limit, equally important: the duty is to give the care you are trained to give, not to attempt what you are not, which can make things worse. A good first-aider is both willing and disciplined.

These two edges answer two different failures. One is the soldier who hangs back because the scene is unpleasant or the casualty is a stranger or a former opponent; the duty says go, act, do the simple things you know. The other is the soldier who, carried away, reaches for a procedure they have only read about; the duty says stop, hand over, get someone who can. The whole of this course is an effort to train you to the line between them.

Care for everyone: the law and the conscience of the Army

A wounded person is a wounded person. The law of armed conflict, and the conscience of the Army, require that care be given to all who need it, by their need and by nothing else. The wounded soldier of the other side, once they can no longer fight, is owed the same care as your own comrade. The injured civilian is owed it. A person's nationality, their conduct, or which side they were on does not change the care they receive.

This is not weakness, and it is not naivety. It is what separates a disciplined, lawful force from a mob, and it is among the clearest marks of the kind of Army the Principality means to be. The casualty in front of you is, in that moment, simply a human being who needs help, and you are the help.

There is a practical side to this principle, because it is sometimes mistaken for an order to take foolish risks. Care is owed to everyone by need, but the order in which casualties are reached and treated is set by need and by safety, not by who they are. When there are more casualties than carers, you sort them by urgency, which is triage (Lesson 08), and may have to give the casualty who can be saved with a quick action priority over one who cannot be saved at all, whichever side either was on. And you still apply scene safety: you do not walk into a hazard merely because the principle of universal care exists. The principle governs whether and how well you care, by need alone; it does not suspend the judgement about when and in what order that keeps you and everyone else alive.

The aims of first aid

Whatever the injury, first aid has three simple aims, in order:

Preserve life, your own first, then the casualty's, then any bystander's.
Prevent the condition from worsening.
Promote recovery, and ease suffering, including by comfort and reassurance.

Two rules sit over these aims. Do no harm: if you are unsure, the safest action is often the simplest, and doing too much can be worse than doing little well. And stay within your training: give the care you have been taught and certified to give, and call for those who can do more.

The aims are not abstractions but the reasons each move exists. Preserve life is scene safety and the primary survey. Prevent worsening is the careful handling, warmth, reassessment, and clean handover that stop a stable casualty from sliding. Promote recovery is the comfort and reassurance you give throughout. Keep them in view and any unfamiliar situation has a shape: make it safe, attack what kills quickest, stop things getting worse, then ease and comfort, all within your training and doing no harm.

The first-aider's mindset: calm, systematic, simple things done well

A casualty scene is loud, frightening, and confusing, and the first thing it attacks is the rescuer's ability to think. The first-aider's most valuable possession is therefore not a piece of kit but a settled, disciplined frame of mind, and it can be trained as surely as any skill. Three habits make it up.

Stay calm. Fear and urgency are natural; the discipline is to act steadily through them rather than be ruled by them. A slow breath as you make your scene-safety check, a level voice to the casualty and on the call for help, a refusal to rush your drill: all of these steady you, and a steady first-aider steadies everyone around them, the casualty included, whose own fear eases when the person helping is plainly in control. Panic is contagious, but so is composure.

Work systematically. Under pressure you do not improvise; you run the drill. Danger, Response, Shout, Primary survey, then MARCH in order, then reassess, the same every time. A memorised order survives the loss of clear thought a crisis brings, so when you cannot think what to do next, you take the next step of the drill. This is why rehearsal matters, and why the practical skills are trained to habit and certified in person, so your hands know the moves when your mind is crowded.

Do the simple things well. Far more lives are saved by basic actions done quickly and correctly than by clever ones done late or badly. Pressure on a bleeding wound, an airway held open, a casualty kept warm, help called early: these unglamorous, well-drilled basics are the substance of saving life in the field, and exactly what a trained lay first-aider can do safely. Resist the pull to reach beyond them for something more impressive. The first-aider who does the simple things well, calmly and in order, saves more people than the one who reaches for what they half-remember and were never trained to do.

The limits of buddy aid: knowing the edge and handing over

The single most important judgement in this whole course is knowing where your competence ends, and stopping there. A course like this can kill if it breeds overconfidence, so it is honest about its limits, and this section states them plainly.

You are a first responder and a buddy-aider, not a medic, a paramedic, or a doctor. What this course trains you to do is the care a competent lay first-aider may safely give: control external bleeding by pressure, packing, or a tourniquet; open and protect an airway by position and simple manoeuvre; recognise and dress wounds and chest injuries within the trained method; keep a casualty warm and treat for shock; move a casualty safely; recognise the major emergencies; summon and hand over to higher care. These are real, life-saving skills, and done well they carry many casualties through the dangerous first minutes to someone who can do more.

Beyond that line lies a range of advanced and invasive procedures that are not buddy aid and are not yours to attempt from this course. Some you may meet later, but only as skills taught and certified in person, under qualified medical supervision, and performed only when you are currently authorised: giving injections or drugs; putting in an airway adjunct, a tube, or a needle; setting up a drip or fluids into a vein; needle decompression of a chest; stitching a wound. None of these is taught here, and none should be attempted on a real casualty on the strength of having read about it. The rule is firm: practise only what you have been trained and currently authorised to do, and never on a real casualty what you have only read.

Handing over at the edge of your competence is not a failure; it is part of doing the job well, and is itself a trained skill. When a medic or higher care arrives, or the casualty needs what you cannot give, you do not cling on. You give a clear handover, what happened, what you found, and what you did, so the next link can pick up without losing ground (Lesson 07 teaches this report in full). Until then you keep working within your training and keep help coming. The mark of a good first-aider is not how much they attempt; it is how well they do the right amount, and how cleanly they pass the casualty on.

The first minutes

The reason first aid matters so much, and the reason every soldier is trained in it, is that the most dangerous injuries kill quickly. A person bleeding heavily from a limb can die in minutes; a blocked airway kills faster still. These are also the injuries that simple, fast first aid can do most about. So the first few minutes after a serious injury are the minutes in which a first-aider, not a hospital, most often decides whether a person lives.

The idea underneath this shapes the whole course. Many deaths from injury are preventable: the casualty did not have to die, and would not have, if a simple action had been taken in time. A great share of preventable death comes from a small number of causes, heavy external bleeding chief among them, an obstructed airway, and a chest injury that stops the breathing, and every one is something a trained first-aider can act on at once, with the kit they carry, where the injury happened. No one can promise a precise deadline, but the shape is firm: the sooner the simple, correct action is taken, the more often the casualty lives.

This is why the course teaches a fast, ordered drill that puts the quick killers first (the MARCH sequence, Lesson 02), and why speed and order matter as much as knowledge. Everything that follows is a way of making the most of those first minutes: getting safely to the casualty, finding the quick killers fast, fixing what you can, and feeding the casualty into the chain of care before the window closes.

In Practice: The Same Skills, Many Settings

Imagine a winter welfare operation in a high valley, the kind of task the RKA is often given. A national has been reported missing in the cold, and your section is searching a hillside above the town. Coming over a rise you see a figure collapsed beside a track, not moving.

Watch how the foundation, and only the foundation, carries you through the opening. You do not run straight to them. You stop and assess the danger: the slope is steep and the light failing, with loose rock above, but no fire, no traffic, no water; the scene is safe enough to work if you mind your footing. You pull on gloves, kneel, and check for a response, speaking and touching the shoulders: "Can you hear me? Open your eyes." There is only a faint groan. So you shout for help, and because two of your section are with you, point at one by name: "Go to the section commander, get a casualty report passed for an ambulance and the rescue team, and come back and tell me it is done." You give the location as exactly as you can, the track and the grid square, so help can find this hillside. Then you begin the primary survey, the quick check for life threats in the order Lesson 02 will drill into you, dealing with anything you find as you find it. You have done none of the treatment skills yet, and already you have done the things that most often decide the outcome: stayed safe, reached the casualty, learned how bad they are, got the next link of the chain moving, and begun the ordered hunt for what is killing them.

The setting differs from case to case; the foundation does not. It might instead be a soldier with a serious wound on exercise, an injured national trapped in wreckage after a storm, or a casualty pulled from a crashed car on the coast road. In each, you keep yourself safe, reach the casualty, check the response, get help moving, work the same ordered drill, deal with the quick killers first, give care within your training, and treat the person with dignity throughout, friend, civilian, or stranger alike. The first-aider who has made this foundation second nature does not freeze when the moment comes, because they already know what they are for and where to start.

Check Your Understanding

Why does the Army train every member in first aid, rather than relying on its medics? In your answer, use the idea of the chain of survival and explain why the first link is so often a soldier who is not a medic.
State the four first actions you take at any casualty, in order, and say what each one is for. Why is scene safety the first, and what is meant by saying "you are no use as a second casualty"?
Who is owed first aid, and on what basis? Explain why the course calls this a mark of a disciplined, lawful force rather than a weakness, and how it sits alongside scene safety and triage without contradicting them.

Reflection (write a short paragraph): Imagine you are the only trained person beside a badly injured stranger, and help is minutes away. What would you want to have made second nature beforehand, the first actions, the calm, the limits you will not cross, so that you act rather than freeze? What does that tell you about how to study the rest of this course, and in particular why the hands-on skills must be drilled and certified in person rather than only read?

Summary

Every soldier is a first responder, because in the field the first help to reach a casualty is almost always a soldier, not a doctor; in a small humanitarian and home-defence force the soldier is often the only trained first-aider present.
A casualty is saved by a chain of survival and a chain of care, from the point of injury to the hospital. Each link must hold; the first link is the soldier who is there, whose job is to do their own link well and keep the next one moving.
Scene safety comes first, every time: stop and assess danger to yourself, the casualty, and bystanders before you treat, because you are no use as a second casualty.
Every case begins with the same first actions: Danger, Response, Shout for help, then the primary survey, the quick ordered hunt for life threats taught in full in Lesson 02.
Call for help early, not late, and keep it coming: pass where you are first of all, then what has happened, how many casualties, and what you need.
Care is offered with consent where the casualty can give it and assumed in their best interest where they cannot; the duty of care is to act within your training, willingly and with discipline, doing the simple things well.
Care is owed to everyone who needs it, friend, civilian, and former opponent alike, by their need alone. Treat every casualty, and the dead, with dignity.
Know the firm limits of buddy aid: you are a first responder, not a medic, and advanced or invasive procedures are taught and certified in person under qualified supervision and are beyond this course. Practise only what you are trained and currently authorised to do, hand over at the edge of your competence, and never attempt on a real casualty what you have only read.
First aid aims to preserve life, prevent worsening, and promote recovery; do no harm, and stay within your training.
The dangerous injuries kill fast and are the ones first aid can do most about, so much death from injury is preventable, and speed, order, and early calls for help save lives.

The Soldier as First Responder
