Lesson Overview

Lesson 04 set out the principles of public order: minimum force, impartiality, discipline under provocation, and the soldier's place behind and beneath the police. This lesson turns those principles into conduct. Public order is a physical, drilled task, and most of what makes it lawful and effective is settled beforehand in training and bearing, not decided in the moment. We cover working under and behind the police; reading a crowd's mood; the cordon and the line as posture and drill; discipline under provocation; command and control; the verbal; the graduated response and the narrow use of less-lethal means; protecting the vulnerable; and the controlled withdrawal and handback. It ends, as the work does, on the plain list of things a soldier must not do.

By the end you will be able to describe how the Army supports the police on a public-order task, read a crowd and recognise the warning signs of disorder, hold your place in a disciplined line, open and close a cordon and channel a crowd on command, act correctly under provocation and missiles, apply the graduated response and the verbal, protect the vulnerable, and carry out a controlled withdrawal and a clean handback.

Key Terms

The line: the disciplined formation a body of soldiers holds facing a crowd, in ranks, shoulder to shoulder, acting together and never as individuals.
Cordon: a manned or marked boundary that controls movement to or from an area, holding a space rather than confronting a crowd.
Channelling: using cordons and lines to guide a crowd along a chosen route or away from a point, so it is directed rather than pushed or blocked head-on.
Reading the crowd: the trained skill of judging a crowd's size, mood, and direction, and seeing the signs that a peaceful gathering is turning disorderly.
The verbal: the spoken part of the task, the challenge, the clear instruction, and the warning, delivered calmly and practised aloud beforehand.
Command and control: the system by which the line acts as one, taking its movement, limits, and level of force from the chain of command and the police lead.
Less-lethal means: equipment such as the shield and baton, and any issued munition designed to control without killing, used only where issued and authorised and within the Rules for the Use of Force.
Controlled withdrawal: the disciplined backward movement of a line, in step and keeping its facing, without breaking ranks or turning to flee.
Handback: the formal return of a task and an area to the police once the need for military support has passed.

Working under and behind the police

In public order the police lead and hold the front. They own the relationship with the crowd, they negotiate, they make arrests, and where a front rank presses against a crowd it is usually theirs. The Army comes in support, doing what a disciplined body does well: holding cordons, standing lines behind the police, lending presence and manpower so the police can concentrate their own people at the point of friction. The soldier is rarely the front rank against a crowd, and never the negotiator. The task is to free the police to police, by holding ground they cannot spare the numbers to hold themselves.

This shapes the whole posture of the soldier on the line. You act within the police plan and under the police lead, passed to you through your chain of command and the liaison between the two. You do not take the initiative, argue with the crowd, or make decisions that belong to the police. Anything that needs deciding, a person to be arrested, a crowd to be addressed, a route to be opened, is referred to the police through the proper channel. The Army's contribution is steadiness and numbers held in good order, and it is spent the moment a soldier steps outside it. This subordinate place is not courtesy but the constitutional ground of the task, drawn from Lesson 04: a small, lightly armed home-defence force of citizens in uniform, supporting the civil power and never supplanting it, governed on home soil by ordinary domestic and human-rights law and not the law of armed conflict, with no enemy on the ground, only nationals of the Principality.

Reading the crowd and its mood

Reading a crowd is a taught skill, not a sense a soldier is born with. Start by fixing one thing: a crowd is not a single thing. The great majority the RKA will ever face are lawful and peaceful, gathered to mark an occasion, to watch, or to protest within the law, needing nothing from the soldier but a calm, watchful presence. Treat that normal case as anything else and you risk creating the very disorder you feared. The trained eye is not hunting for trouble in every face; it reads the ordinary mood of a lawful crowd so it can catch the rarer moment when that mood begins to turn.

A crowd has states along a continuum that moves both ways. The relaxed crowd is at ease, spread out, attention scattered. The expectant crowd is waiting, its attention focusing. The confrontational crowd is testing a line, watching to see what it will do. The hostile crowd is acting against the line, pushing, throwing, trying to break it. The skill is to place the crowd on this continuum and to feel its drift: one settling back toward relaxed needs only patience, while one sliding toward confrontational needs the line at its steadiest.

The warning signs are concrete. Watch for the crowd drawing together and forward as the loose spread tightens into a press; for the noise changing, a single chant taking hold or a sudden hush before a surge; for faces turning to the line rather than to whatever they came for; for missiles being gathered, bottles held, a stone picked up, a placard turned for its stick; for masks or covered faces; for the front rank stiffening, arms linking, a few pushing others forward. None alone makes a riot. Together and trending one way, they are the crowd telling you what it is about to become, and they are read calmly and reported, not acted on alone.

The most important lesson here is the danger of the small group inside the larger peaceful one. A crowd of a thousand may be entirely lawful while a knot of twenty within it means trouble and uses the thousand as cover and as a stage. The error to avoid above all is treating the whole crowd as the few. A line that answers the twenty by pushing the thousand, by force that touches the curious, the frightened, and the children among them, has done the troublemakers' work: it has turned a peaceful crowd hostile and handed the few what they wanted. So reading a crowd is the discipline of distinction: see the few who are the problem, keep the response to them and refer it to the police, and punish the many not at all.

   READING A CROWD: the continuum and the warning signs

   relaxed  -->  expectant  -->  confrontational  -->  hostile
   (at ease)     (waiting)        (testing line)       (pushing,
                                                        throwing)
        <------- patience and bearing bring it back -------

   Warning signs of a wrong-way drift:
     - the crowd draws together and forward (a press forms)
     - the noise changes (a chant takes hold; a sudden hush)
     - faces turn to the LINE, not to what they came for
     - missiles gathered (bottles, stones, a placard stick)
     - masks or covered faces appear; the front rank stiffens

   The trap: a small hostile group inside a large peaceful crowd.
     Answer the FEW, refer them to the police, touch the MANY not
     at all. Push the whole crowd and you do the few a favour.

The cordon and crowd management

The most common public-order task the Army will be given is the cordon: a line held to keep a space, seal an area, hold a route, or separate one part of a crowd from another. A cordon is not a fight; it is a boundary, and its strength is that it holds without drama. The soldier on it should know what is being protected, where the police lead stands, how access is controlled, the call for assistance, and the signal to withdraw. People to be turned away are turned politely and shown the way round where there is one; people to be let through are passed by the agreed procedure. The cordon manages the crowd by being clear, calm, and immovable, not by pushing.

A cordon has a shape, and the shape is what makes it strong. The soldiers stand with even spacing, close enough that no one slips between and each can support a neighbour, far enough apart to act without fouling one another, with a second rank behind to fill gaps, relieve the tired or injured, and add weight if the cordon is pressed. The line keeps its facing to the crowd and anchors its flanks where it can, against a building, a vehicle, another cordon, so the crowd cannot walk round the end. Mutual support is the whole idea: no soldier holds the cordon alone, and the cordon is only as good as its weakest gap. One that keeps its spacing, facing, anchored flanks, and second rank holds against far greater numbers, because it holds as one boundary and not a row of individuals.

A cordon is opened and closed on command and by drill, never by a soldier deciding alone to let someone through. When a person or vehicle must pass, the order is given, a controlled gap is opened at a named point, covered by the soldiers either side and by the second rank, the passage is made, and the gap closes again at once. An unmanaged gap is an invitation, and a crowd reads an open cordon as a way through. The cordon opens where it is told, to whom, for as long as it is told, and closes the instant the passage is done, covered throughout.

                    gap covered by neighbours + 2nd rank;
                    passage made; gap CLOSED at once

Beyond holding a boundary, the cordon and the line manage a crowd best by channelling it rather than confronting it. A crowd met head-on and blocked has nowhere to go, and its pressure builds against the line; the same crowd offered a way, guided by cordons along a chosen route or away from a sensitive point, moves off and its pressure drains. Channelling is the difference between a wall and a riverbank: the wall is pushed until it gives, while the bank simply shapes where the water goes. So the question on the line is rarely "how do we stop this crowd" but "where do we want it to go, and how do we make that its easy way to move." Where there is a way round, the crowd is shown it; where a point must be kept, the crowd is turned along the front of the cordon and led past rather than held nose-to-nose. Confrontation is the last resort and the most dangerous.

Crowd management is mostly the management of movement and tension, and the line answers each crowd state by its bearing far more than by force: the relaxed crowd is left be, the expectant crowd watched, the confrontational crowd met with a steady line and a way offered, the hostile crowd held against and handed to the police lead. A steady, open, unprovocative posture can settle a crowd as surely as a hard one inflames it, and the continuum runs both ways. The aim throughout is the lowest state the situation allows.

The discipline of the line

The line is the heart of public-order drill, and its whole strength is that it acts as one body. Soldiers stand steady, silent, and together, in their ranks, and they do not move or speak except on command. A line that holds its bearing communicates control; a ragged line that argues back and fidgets invites the crowd to test it. The single most important fact about the line is that the soldier never acts alone within it. Individual initiative against a crowd is not courage; it is the thing that breaks formations and ends careers.

The posture is taught, not a mood. The soldier stands square to the crowd, feet about shoulder-width and braced against being pushed off balance, holding ground without leaning in or shrinking back. The hands are still and visible, not jabbing or fidgeting; a shield protects rather than threatens, and a baton stays at rest until drawn on command or under the rules. The face is calm and the eyes are up, taking in the whole crowd and its edges rather than locking onto the one person shouting, because a soldier who fixes on a single tormentor stops reading the crowd and starts taking the provocation personally. The mouth is shut unless the verbal is required. The whole posture says, without a word, that the line is steady and not to be moved, and that does more work than force.

From this follows the cardinal rule: do not be drawn out of the line. A crowd, or one person in it, will try to provoke a soldier into stepping forward, into a chase, into a personal quarrel, because a soldier drawn out is isolated, and an isolated soldier is a gift to a hostile crowd and a worse one to a camera. Where a person must be taken from the crowd, it is done on command, by the drill, with the line covering, not by one soldier lunging. The injured or exhausted are replaced on command from the rank behind, at a pace that never opens a gap. The line advances, when it must, in step and at a measured pace to move a crowd back, never as a charge to engage individuals. Everything is together, on command, by the drill.

The soldier's discipline under provocation

The hardest thing the line asks is not physical effort but self-control: to take provocation and not answer it. Lesson 04 named this the decisive quality, and here it meets three concrete tests, each worth settling beforehand, because a soldier who has thought them through is far likelier to hold than one meeting them cold.

The first is abuse. Insults, taunts, and foul personal remarks will be shouted into a soldier's face, deliberately, by people who know a goaded soldier hands them a victory. The drilled answer is bearing: hold the posture, keep the eyes up and across the crowd, say nothing that is not required, and let the abuse pass. The second is spitting, harder because it is a physical violation and the instinct to react is stronger; the answer is the same, and must be settled in advance for that very reason: hold the line, do not strike, do not lunge, and where an offence has been committed refer it to the police rather than settle it personally. The third is the thrown object, a bottle, a stone, or a coin that lands and may hurt; close up behind shields and cover, ride it out in good order, and do not break ranks or chase the thrower, who is dealt with by the police from behind the line.

Running through all three is the danger of the single soldier who breaks ranks to retaliate. The greatest threat to a public-order operation is often not the crowd but the one soldier who loses control: stung past bearing, they are for that instant not a disciplined servant of the law but a person in a fight, leaving a gap where they stood and giving the camera a picture of a soldier charging the public. One such act can trigger the escalation that good order had avoided, turn a manageable crowd hostile in a moment, and spend in a minute the trust the Army built over years.

This is where the section commander's quiet word does its work, and it is a taught part of the drill. A soldier near breaking, half a step forward, hand rising, is not brought back by a shouted order the crowd can feed on. They are brought back by the steady, low word of the commander beside them, calling their name, telling them to hold, to step back, to leave it to the police. The word is quiet on purpose: it steadies the soldier without giving the crowd a drama, and it reminds them, in the only voice that can reach them in that moment, that they are not alone and not acting on their own account but holding a line under command. A good section commander watches their own soldiers as closely as the crowd, and is at the shoulder of the one nearing the end of their patience before the half-step becomes a blow. Bringing a soldier back into the line is as much a part of holding it as facing the crowd.

To stand under abuse, spitting, and missiles in disciplined silence, in a line that does not break, is the most demanding act of self-control the work asks, and the act on which the whole task depends. It is not passive and it is not weakness. It holds only because it was practised; in the moment, only trained drill will hold.

   THE WRONG SIDE WINS          THE LINE WINS QUIETLY

Command and control on the line

Everything the line does well, it does because it acts as one under command. The line takes three things from above and never from individual choice: its movement, its limits, and its level of force. It advances, withdraws, opens or closes a gap, draws batons, or takes any other action on command, given by the chain of command in step with the police lead, so the whole line acts together and no soldier moves on their own account. Acting on command is not the surrender of judgement; it is the only way a body of soldiers can present one steady, lawful face to a crowd instead of a scatter of individual decisions, any one of which could be the spark.

Before a soldier ever stands on a line they should know the briefed limits of the task. A good public-order brief makes plain what is being protected or held, where the police lead is and how liaison runs, the boundary to hold and the routes by which a crowd may be channelled, the procedure for opening and closing the cordon, the call for assistance, the signal and route for withdrawal, and the level of force authorised, including whether and on whose order any less-lethal means may be used. Know the brief and you know the limits of your own conduct in advance; if you do not, ask before the line forms rather than guess on it. The limits in the brief are the working edge of the Rules for the Use of Force on that task, and they are obeyed as the rules themselves are.

The third strand is communication, which runs both ways and must be disciplined in both. Commands and information pass down the line, by voice and the agreed signals, so the order to hold, step back, or open a gap reaches every soldier at once. And what a soldier sees passes up: the gap forming on the flank, the press building at one point, the small group gathering missiles, the elderly person going down in the crush. The soldier on the line is the eyes of the command; a quiet, accurate report up the chain is part of holding the line, while a soldier who acts on what they see instead of reporting it has broken the system that makes the line strong. Pass up what you see, act on what you are told.

The verbal, practised aloud

Long before a shield or baton, the soldier's first tools are voice and bearing, and the verbal is a skill to be built, not improvised. There are three parts. The challenge establishes who you are and what you require. The clear instruction tells a person plainly what to do, briefly and with a reason where one can be given: "Please step back," "I cannot let you through here, the way round is to your left," "Please keep to the pavement." The warning makes plain, before any force and while it is still safe to give it, what will happen if the instruction is not obeyed. Each is delivered calmly, in short words, with respect kept even under abuse, because a calm word given early settles far more than force given late.

Practise the verbal aloud, with a partner playing the difficult part, because the calm voice must be the one that comes out under pressure, and it will not unless it has been trained. The words that lower tension are calm, brief, respectful, and give a reason: "please" and "thank you" belong in almost every instruction, and "sir" or "madam" signals respect even to someone abusing you. The words that raise it are the curt order, the sarcasm, the personal remark, the reply to an insult. A soldier who answers provocation with a sharp tongue has not asserted authority; they have handed the crowd, and the camera, what they wanted. In public order the tongue is a more dangerous instrument than the baton, and the discipline to say nothing is often the most professional thing a soldier can do.

   THE VERBAL: three parts, practised aloud

   CHALLENGE     who you are, what you require
                 "Royal Army. Please stop there."
   INSTRUCTION   what to do, plainly, with a reason
                 "Please step back; the way round is to your left."
   WARNING       what happens if it is not obeyed, while still safe
                 "If you do not step back, you may be moved back."

   Lowers tension: calm, brief, "please/thank you", "sir/madam",
                   a reason given, and SILENCE where speech is not needed.
   Raises tension: the curt order, sarcasm, the personal remark,
                   any reply to an insult. Never answer abuse.

The graduated response in practice

The Rules for the Use of Force are the same here as everywhere, applied through the graduated response, rising only as far as necessity requires and falling the moment it allows. On the line the ladder runs exactly as the Rules state it: presence, the visible, disciplined standing of the Army, which settles most situations by itself; then verbal, clear instruction, warning, and de-escalation; then control, proportionate, trained restraint, only if the lower steps fail and it is necessary; then defensive force against assault; then less-lethal means, where issued and authorised; and then lethal force, only as a last resort, only against an imminent threat of death or serious injury, and only when nothing less will serve. Each step up is a decision, and so is each step down: the line that has been pushed and has held returns to its still, quiet default the instant it is safe. A soldier need not attempt a lower step where doing so would be unsafe or plainly futile against an immediate, grave threat; but the governing principles, lawful authority, necessity, minimum force, proportionality, distinction, humanity, and accountability, apply at every level.

   THE GRADUATED RESPONSE (as in the Rules for the Use of Force)

      ^   6. LETHAL FORCE        last resort; imminent threat of
      |                          death or serious injury; nothing
      |                          less will serve
   rise  5. LESS-LETHAL MEANS    where ISSUED and AUTHORISED
   only  4. DEFENSIVE FORCE      to defend against assault
   as    3. CONTROL              proportionate, trained restraint
   need  2. VERBAL               instruction, warning, de-escalation
      |  1. PRESENCE             the still, disciplined line  <-- default
      v   ... and FALL back the moment necessity allows.

The narrow point to fix is the use of less-lethal means. They are used only where issued for the task and authorised, and always within the Rules for the Use of Force; on the line, that authorisation reaches the soldier as the briefed limit and the order from the chain of command, not as a personal choice. The shield protects, not strikes, except where a strike is authorised; the baton is an instrument of control, drawn on command or under the rules, never a punishment, a prod, or a gesture. In a crowd the question is never only "could I use force on this person" but "who else will this force touch," because a crowd holds the curious, the old, the frightened, and children, and force proportionate against one person can be wholly disproportionate among many. This is the principle of distinction in the press of a crowd: force is directed only at those who present a threat, and care is taken to protect everyone else. Force in public order is measured not by effect but by the least that meets the lawful aim, and it stops the moment it is no longer needed. The right to self-defence remains throughout: against an imminent threat of death or serious injury to themselves or others, a soldier may use such force as is necessary and no more than is reasonable in the circumstances as they honestly believe them to be.

Protecting the vulnerable

A crowd in disorder is not a single hostile thing. Within it and around it are people who never sought trouble and are now in danger: the injured, the young, the old, the frightened, those knocked down, cut off, or simply caught in a place that has turned ugly. Part of the soldier's task, even while holding the line, is to see these people and protect them. The impartiality of the Army is not suspended in disorder. The Army upholds the lawful peace for everyone, including those in the crowd who mean no harm, and protecting the vulnerable is part of what the line is for, not a distraction from it.

In practice this is its own small drill. When a person goes down in the crush or a frightened family must be brought clear, the nearest soldier sees it and reports it up the line; on command, never by one soldier wandering off, the person is brought in behind the line through a controlled gap, covered either side, exactly as any controlled opening is made. Behind the line they are given what first aid the soldier's training allows, assistance is called, and they are kept safe from the crowd and the weather until they can be passed to the medics or the police. The same care that Lesson 07 owes a person held, humane treatment, dignity, and no making a spectacle of anyone, is owed here, because the principle is one: a person in the Army's care is in the Army's care.

The controlled withdrawal and handback

A line must sometimes give ground, and the withdrawal under provocation is the hardest drill of all. It is done on command, in step, the line keeping its facing and order, never turning to flee or breaking into individuals. A disciplined withdrawal, made deliberately and in good order, is not a defeat; it lowers the temperature, denies the crowd a rout to chase, and keeps the formation intact and able to hold again. A broken withdrawal, soldiers turning and running, is a genuine defeat, dangerous to them and damaging to the Army, and the difference between the two is drill.

The controlled withdrawal has the same parts as the rest of the line's drill, performed backward. The order is given by the chain of command in step with the police lead, and a route and rally point are part of the brief, so the line knows where it is going and is not improvising under pressure. The line steps back together and in step, keeping its facing so it never turns its back, keeping its spacing so no gap opens, and often rank passing rank, the rear rank stepping back to a new position while the front holds, then the front passing through to hold again, so there is always a facing line between the crowd and the withdrawing soldiers. The pace is measured, neither a dawdle that invites the crowd on nor a scramble that becomes a rout. Done this way, the withdrawal reads to the crowd not as flight but as the line choosing to move, which gives them nothing to chase.

Every public-order task ends not when the soldiers leave but when the task is properly handed back. As soon as the police can manage with their own resources, the military support is withdrawn and the area and task returned formally to the police, who held primacy throughout. The discipline of the handback is the discipline of leaving the ground calm: the support is not snatched away in a way that reopens what it closed, but stepped down in good order, in step with the police, so the line's departure lowers the temperature rather than raising it. The handback is recorded, as any use of force during the task is recorded, honestly and fully through the chain of command, because every use of force may be questioned afterwards and every member is answerable for the force they use. Handing back promptly is the operation doing what it exists to do: adding the Army's support for exactly as long as it is needed and not a moment longer, then stepping back out of the civil space and leaving the police in the place that is rightly theirs.

In Practice: A Cordon Outside the Harbour Gate

A demonstration outside a port town's harbour gate grows large and angry, and a platoon is sent, at the request of the police and under their direction, to hold a cordon across a side approach while the police hold the front. Before the line forms, the platoon is briefed: what the cordon protects, where the police lead stands and how liaison runs, the boundary and the channelling route, the procedure for opening and closing the cordon, the call for assistance, the route and signal for withdrawal, and the level of force authorised. The soldiers form their line with even spacing and a second rank, flanks anchored on the gate wall and a parked lorry, and hold the boundary steady and silent, faces calm and eyes up across the whole crowd.

The commanders read the crowd as it builds. For a time it is expectant and lawful, and the line does almost nothing, which is exactly right. Then a knot of perhaps a dozen works to the front, faces turning to the line, a chant taking hold, a few bottles appearing: a wrong-way drift. The line steadies; it does not push the hundreds of peaceful people behind the dozen, because answering the few by acting against the many would do the troublemakers' work. A man from the knot pushes forward, screams abuse into a young soldier's face, then spits; the soldier holds his bearing, keeps his eyes up, and does not move. A bottle breaks near the line; the soldiers close up behind their shields, ride it out, and do not chase the thrower, who is identified and dealt with by the police from behind. Beside the young soldier, a second nearly breaks, half a step forward, hand rising; his section commander's quiet word, low and by name, brings him back before the half-step becomes a blow.

The crowd presses, and rather than hold nose-to-nose the police and the line channel it: a way is opened along the front of the cordon and the bulk of the crowd is guided past and away from the gate, its pressure draining. An elderly woman is knocked down in the press; her plight is reported up the line, and on command a controlled gap is opened, covered either side, and two soldiers bring her in behind the line, give what first aid they can, keep her clear of the crowd and weather, and call for the medics. When the crowd thins and the police signal that they can manage, the platoon withdraws on command, in step, keeping its facing and spacing, rank passing rank back to the rally point, leaving the ground quiet behind it. The cordon is handed back formally, and the use of force, the bottle, the woman, the abuse, the controlled openings, is recorded honestly that evening through the chain of command. No soldier was drawn out, none retaliated, and none became the story. The platoon did little that looked dramatic, and that quiet, disciplined holding was exactly the task.

Check Your Understanding

Why is the Army most often holding cordons and lines behind the police rather than the front rank against a crowd? What does the soldier's place in support require of how they act on the line, and how does reading the crowd help the line answer the few troublemakers without acting against the many?
A soldier on the line is screamed at and spat at, and then a missile is thrown near them. Describe the correct response to each, explain why being drawn out of the line to retaliate is the worst thing a soldier can do, and say what part the section commander's quiet word plays.
Explain the discipline of the controlled withdrawal and of the handback. Why is a withdrawal made in good order not a defeat, while a broken one is, and what does it mean to leave the ground calm?

Reflection (write a short paragraph): This lesson says that to stand under abuse, spitting, and missiles in disciplined silence, in a line that does not break, is the most demanding act of self-control the work asks, and that it holds only because it was practised. Think about a moment on the line when you might be tempted to step out, to answer back, or to retaliate. What understanding, settled and rehearsed beforehand, would keep you in your place? How would a comrade's, or a commander's, quiet word help, and why is holding the line both the safer and the more professional response?

Summary

The police lead and hold the front; the Army most often provides cordons, lines, presence, and manpower behind and under them, rarely the front rank against a crowd. The soldier acts within the police plan, under domestic and human-rights law and the Rules for the Use of Force, and refers decisions that belong to the police.
Reading the crowd is a trained skill: judge its state along the continuum from relaxed to hostile, watch for the warning signs of a wrong-way drift, and above all answer a small hostile group without acting against the larger peaceful crowd around it.
The cordon holds a boundary by being clear, calm, and immovable, with even spacing, a second rank, anchored flanks, and mutual support; it is opened and closed only on command with the gap covered, and it manages a crowd best by channelling it rather than confronting it head-on.
The line is steady, silent, and together, acting as one on command and never as individuals, in a taught posture: square to the crowd, hands still and visible, eyes up and across, mouth shut unless the verbal is required. The cardinal rule is not to be drawn out of it.
Under provocation, abuse, spitting, and thrown objects, the line holds, closes up, and never breaks ranks, chases, or retaliates as an individual; the section commander's quiet word brings back any soldier who starts to break. Command and control supply the line's movement, limits, and level of force; communication passes up what is seen and acts on what is ordered.
The verbal, the challenge, the clear instruction, and the warning, is practised aloud so the calm voice comes out under pressure. The graduated response runs exactly as in the Rules for the Use of Force, with less-lethal means reaching the soldier as a briefed, authorised order, the shield to protect and the baton to control, and force measured by the least that meets the lawful aim and by who else it touches.
The vulnerable caught up in disorder are protected even while the line is held, brought in through a controlled gap and cared for with the same dignity owed to a person held in Lesson 07. The task ends in a controlled withdrawal in good order, rank passing rank and facing kept, and a prompt, recorded handback that leaves the ground calm and returns primacy to the police.
The plain don'ts: do not be drawn out of the line; do not retaliate personally; do not punish the many for the few; do not escalate; do not act on what you see instead of reporting it; do not take a souvenir or a trophy photograph; do not become the story.
