Living in the Field

Lesson Overview

This is the last lesson of the course, and the one that keeps the others standing. A soldier who can navigate, conceal, observe, and move is still no use if they fall ill, freeze, blister, or collapse from thirst within a day of arriving. Living in the field is the skill of staying fit to do the job over time, and it rests on one hard principle: a soldier who does not look after themselves becomes a casualty, and a casualty is no longer a searcher or a worker but a burden the others must carry.

Its drills are proved on the ground. The value of dry socks, of a warm brew at the right moment, of a shelter rigged before the rain, is learned cold and tired, under instruction, until the habits hold without thought. Where this lesson touches on injury it points to the Combat First Aid course, which teaches the treatment of cold and heat injury in full; here the work is preventing those casualties, not treating them. Where it touches on the science of water, hygiene, and sanitation, it points to the Field Health, Hygiene and Sanitation course. By the end you will be able to run the field routine through a daily cycle, manage and treat water before drinking, eat and ration to stay fuelled and warm, care for your feet as a first-rank task, keep yourself and your kit clean and dry, site and pitch a simple shelter, sleep and rest under discipline, keep your equipment serviceable, and explain how all of this serves the long-haul effectiveness the RKA's field tasks demand.

Key Terms

• Field routine: the working rhythm of a soldier or section in the field, run as a daily cycle, in which task, rest, food, and the maintenance of self and kit each get their turn.
• Personal administration: the soldier's own upkeep, drying out, eating, foot care, hygiene, sorting kit, done whenever the chance comes, not when it is convenient.
• Stand-to: the dawn and dusk routine in which the section comes fully alert and ready at the two times of poorest light, the natural moments for things to go wrong.
• Water discipline: the deliberate management of drinking and resupply so that a soldier neither runs dry nor wastes water, and treats it before drinking when its source is uncertain.
• Hot spot: the patch of friction on the foot that warns of a blister to come, treated at once before it breaks the skin.
• Basha: a simple shelter rigged from a poncho or shelter sheet, sited out of the wind and off wet ground, that gives somewhere to dry out and rest.
• Serviceable: kept clean, dry, working, and stowed in its known place, so that a soldier or weapon is ready for use when needed.

Field living is a discipline

A casualty is a double loss: one fewer to do the work, one more to be looked after. A section that loses one soldier to blistered feet, one to a chill, and one to a stomach upset has lost a third of its strength without anyone meeting it, and lost it to neglect. Looking after oneself in the field is not softness; it is the discipline that keeps a soldier effective when the easy thing, skipping the meal, leaving wet socks on, putting off the brew, lying down without rigging shelter, would slowly turn them into the casualty the others must rescue. Everything that follows is the practice of that discipline.

The field routine and the daily cycle

In the field there is rarely a tidy time set aside for rest or food; the soldier takes them in the rhythm of the task, and that rhythm is the field routine. It balances four things that all must happen: the task itself; rest, taken whenever the task allows, because tiredness erodes judgement and footing; food and water, taken in turn so no section goes hungry while another eats; and maintenance, of the soldier and of the kit. Over a day and a night these settle into a cycle, and learning that cycle is the heart of this lesson.

The governing habit is to do personal administration whenever the chance comes, because the convenient time never arrives. When there is a pause, the disciplined soldier uses it in a fixed order of priority: first make the position safe and post a watch, then attend to the feet and any dry kit, then eat and refill water, and only then rest. The order puts the slow-burning casualties, wet feet and an empty body, first, before the soldier is too comfortable to move.

The section does its administration in turn, never all at once, so that security and rest are both kept. A section in good routine works in halves or thirds: while one part eats, dries out, and tends feet, another keeps watch and stays ready, and they rotate, so at no moment is the whole section heads-down and blind. A section that all brews up together has, for those few minutes, no one watching and no one ready, and that is exactly the moment a real task punishes.

Two points of the cycle get their own drill: dawn and dusk, the stand-to. These are the two times of poorest light, when shapes are hardest to read, and the long habit of armies is to be fully alert and ready at both. The dusk routine is run as the light fails: the section comes to readiness, last light is used to confirm the layout of the position and the arcs each soldier watches, kit is brought in close and stowed by feel for the night, and any administration that needs the light, a last look at the feet, a check of the map, is finished before it is gone. The dawn routine is its mirror: the section is alert and ready before first light, holds through the half-light until full day confirms the ground is as it was left, and only then stands down into the day's tasks. A soldier who lets dawn and dusk find the section half-asleep and half-packed has thrown away the two points in the cycle most worth holding.

Water

A soldier cannot work, think, or recover without water, and the need for it is greater in the field than in barracks, because hard work loses water fast, in cold and wet as well as in heat, where the soldier may not feel thirsty enough to keep up. Water discipline has three parts: drink enough, ration and plan resupply, and treat everything from an uncertain source.

Drink enough, and drink ahead of thirst. Thirst lags behind the body's real need, so drink regularly in small amounts rather than in great gulps when finally desperate, and drink before a hard task, not after it has wrung you out. Drink with and after meals, and keep sipping through the day. The clearest sign you are drinking enough is plentiful, pale urine; dark, scant urine means the body is already short. In the cold this is easily neglected, because a soldier does not feel thirsty and resents stopping in the wet to drink, yet hard work in the cold loses water just as surely, and a dehydrated soldier is more prone to cold injury besides. So in cold weather a soldier must drink deliberately, by the routine and not by thirst.

Ration and refill. Know how much water you carry, know where the next water comes from, and manage the gap between. Fill at every chance: top the bottles up whenever a safe source or a resupply offers, rather than running them down and hoping. Where water must be carried and cannot be quickly replaced, it is not wasted on what a brew or a wash could do without.

Treat all field water. Water from an uncertain source, a stream, a tank, standing water, must be treated or purified before drinking, because water that looks perfectly clean can carry the bacteria, viruses, and parasites that cause the field's commonest illness, infectious diarrhoea, which empties a soldier of fluid and puts them down as surely as any injury. The standard method is the issued purification tablets: fill the bottle with the cleanest water you can find, add the tablets as the issue directs, replace the cap and shake, then loosen the cap and tip the bottle so a little treated water runs over the threads and the lip, retighten, and wait the full stated time before drinking. That wait is not optional; it is the time the chemical needs to do its work, and drinking early wastes the treatment. Where tablets are not to hand, bringing the water to a rolling boil for several minutes is a sound alternative, after which it must be kept covered so it is not contaminated again. The fuller drill, the methods, the timings, and the checking of treated water, is taught in the Field Health, Hygiene and Sanitation course; here the rule is simple and absolute: in the field, you treat the water. The dangers are dehydration at one end and waterborne illness at the other, and both are casualties this discipline exists to prevent.

Food and ration discipline

Food is the soldier's fuel, and in the field the danger is not going hungry by accident but failing to eat enough through neglect or distaste. The soldier eats rations issued for the task, and the discipline is to eat enough, taking food in the field routine whenever the chance comes, even when tired or not much hungry, because the work draws heavily on the body and a soldier running on empty fades fast in strength, warmth, and judgement.

Energy matters most in the cold: the body burns fuel to keep itself warm, so eating is a defence against the cold, and a soldier on a cold task eats more, not less. Eat all of the ration, not only the parts you like, because the items you are tempted to leave are often the ones carrying the energy and the salts the body needs. A warm meal or a hot drink warms the body from the inside and lifts the spirits when both are low, which is why a brew at the right moment is worth far more than the few minutes it costs.

Cooking is done with discipline. Use the issued stove or heating means rather than open fire where you can, because a fire is slow, smoky, hard to control, and a beacon that can be seen and smelled at a distance; light and warmth that should not be shown are part of concealment as much as of safety. Cook in turn within the section, so security and the cycle are kept, and never leave a stove burning unattended. Ration discipline also means looking after the food itself: keep it dry and protected in the pack, inspect tins and packets before use, and discard any tin that is leaking, swollen, or bulging, or any packet that is split or spoiled, because spoiled rations cause exactly the stomach illness that takes a soldier out of the field.

Last comes rubbish discipline, both a health rule and a field-craft one. All packaging, scraps, and waste are collected, bagged, and carried out, not buried loosely and not scattered, because food waste left lying draws flies and animals, spreads germs from waste to the next meal, and leaves an obvious sign that a section has been here and where it went. A clean position is a healthy position and a concealed one. The soldier who eats steadily through a long task, keeps their rations sound, and leaves nothing behind stays strong to the end; the one who skips meals to save time or weight, or fouls their own position with waste, is borrowing against their own effectiveness, and the debt comes due at the worst moment.

Foot care

Of all the field-living drills, foot care comes first, because a soldier moves on their feet and ruined feet end a soldier's usefulness faster than almost anything else. A soldier whose feet have become raw, blistered, and infected cannot walk, and so must be carried by the very comrades they were meant to help. Feet are tended as a first-rank task, at every halt, not at the end of the day when the damage is already done.

It begins before the field, with the boots. Boots must be well fitted and, above all, broken in over time before a long task; a new, stiff boot worn on a hard march is a guarantee of blisters. Boots are kept in good order, laced properly so the foot does not slide, and dried out when they are soaked, because a wet boot rubs and chills.

Then the socks. The drill is plain and it is the heart of foot care: keep the feet dry, and change into clean, dry socks whenever the chance comes. Carry several pairs, kept dry in a waterproof bag. When you change them, air and dry the feet, and dry the socks you have taken off, hung where they can dry or carried inside clothing against the body, so a dry pair is always coming back into the cycle. In cold or wet conditions, inspect your socks and feet at least once a day as a fixed part of the routine. A little foot powder helps keep the skin dry, and is well worth carrying for a soldier prone to soft or sweaty feet.

The early enemy is the hot spot, the patch of friction and heat that warns of a blister before the skin breaks. Deal with it the moment it is felt: stop, take off the boot and sock, and cover the spot, with a plaster, tape, or a blister dressing, before it goes any further. This is why feet are tended at the halt and not at day's end: a hot spot caught early is a minute's work, while a burst blister hours later is a casualty. If a blister has already formed, keep it clean, do not tear the skin away, cover it to protect it from further rubbing, and watch it for the redness, heat, and swelling that mean it is becoming infected; the treatment of an infected or serious foot injury belongs to the Combat First Aid course. Finally, wash and dry the feet when the routine allows, because clean, dry feet resist both blisters and the fungal infections that thrive in a warm, damp boot.

Personal hygiene in the field

Beyond the feet, small neglects of cleanliness accumulate into casualties, and the soldier guards against them as a matter of discipline. Close, tired, dirty living breeds the illness that takes a section apart without a shot fired, and the defences are simple habits kept up under conditions that make it tempting to drop them.

Keeping clean. A full wash is rarely possible in the field, so wash the parts that matter with a cloth and a little water: the feet, the armpits, the groin, and any place that sweats or stays damp and so breeds rashes and infection. Keep the skin as dry as you can. Loose-fitting clothing helps, by letting air move and the skin breathe; tight clothing traps damp and chafes.

Teeth. Brush the teeth and gums after meals, or at the least once a day, because tooth decay and gum infection are not minor in the field, where they cannot easily be treated, and they can lay a soldier low. Where toothpaste runs out, brushing without it is still worth doing, and the mouth can be rinsed with treated water through the day.

Hands. This is the hygiene drill that prevents the most illness, because the hands carry germs to the mouth. Wash the hands with soap and treated water, or clean them with the issued means where water is short, at two times above all: before handling food or eating, and after using the latrine. Wash them too after handling anything that can pass on germs, and frequently through a long working day. A soldier who eats with dirty hands after a job is the most likely person in the section to bring on the diarrhoea that empties them out.

Keep, too, the eating utensils clean, washed in treated water or disinfectant, because a dirty mess tin is a sure way to a stomach upset. The fuller treatment of field hygiene and the disposal of human waste, the siting of latrines, and keeping disease away from where a section eats and sleeps, is carried in the Field Health, Hygiene and Sanitation course. Each of these habits is a defence against the slow casualties, and the soldier who keeps them stays in the fight.

Shelter

A soldier who can rest dry and out of the weather recovers; one who lies in the wet does not, and chills. So when the task allows a halt of any length, the disciplined soldier rigs a simple shelter, a basha, from a poncho or shelter sheet, before the weather turns rather than after the rain has started.

Siting comes first, and it decides whether the shelter helps. Choose ground that is off the wet: a slight rise rather than a hollow, where rainwater runs away from you and not pool beneath you, and clear of any channel that will become a stream in the night. Get out of the wind, in the lee of a slope, a wall, a hedge, or trees, because wind strips heat and drives rain in under cover. Keep the site concealed, using the same ground and shadow taught in the use-of-ground lessons, so a shelter does not become the sign that gives a position away. Avoid dead ground that floods, the foot of a steep slope where water and cold air gather, and any lone tree or feature that draws attention.

Pitching a basha is quick once practised. Run a line, paracord or the sheet's own cords, between two firm points, two trees, a wall and a post, at low height, and hang the sheet over it to make a sloping roof, or pitch one edge low to the ground and the other raised to make a lean-to that sheds the wind. Pull it taut so rain runs off and does not pool and sag through, peg or weight the lower edges down, and angle the open side away from the wind and rain. Keep the profile low: a low shelter is warmer, stronger in wind, and far less visible than a high one.

The drill soldiers most often forget is insulation from the ground. More heat is lost into cold, wet ground than most expect, so getting up off it matters as much as the roof overhead: use a roll-mat, or in its absence dry grass, bracken, leaves, or a groundsheet, anything that puts a dry, insulating layer between the body and the earth. A soldier who rigs a tight, low, well-sited basha and gets up off the ground has somewhere to dry out, eat, and sleep, and comes through the night fit to work; one who lies down on bare wet ground under a sagging sheet is wet, cold, and half a casualty by morning.

Keeping yourself and your kit dry and warm

Shelter is one half of staying warm and dry; clothing discipline is the other, and the two go together, because wet clothing chills a soldier fast even when the air is not bitter. In a cold, wet, maritime climate the chief danger is the cold and the wet together, and its end point is hypothermia, the dangerous fall in the body's core temperature; on the other side, a soldier working hard in heavy kit can overheat and suffer heat injury even on a cool day. The first response to both belongs to the Combat First Aid course, and the fuller art of operating in severe cold belongs to the Cold-Weather Operations and Survival course; field living keeps a soldier well clear of either casualty.

The soldier's main defence is clothing discipline, and it has two rules.

The first is layering: wear several lighter garments rather than one heavy one, so warmth can be adjusted to the work. Take a layer off before a hard task or a climb, before you begin to sweat, because sweat soaks clothing as surely as rain and then chills you the moment you stop; and put a layer back on at a halt, before the chill of standing still sets in. The soldier who marches in everything until soaked with sweat, then stops and freezes, has wet themselves from the inside.

The second is staying dry, and its core is the dry set kept back. Keep one complete dry set of clothing, and above all dry socks, sealed in a waterproof bag and never worn until you are settled for the night under shelter; that dry set is what lets you recover, and a soldier who soaks it on the first wet leg has nothing to change into. Treat sweat as a wetting agent as real as the weather, dry out wet kit whenever shelter and the routine allow, and keep the rest of the kit dry too, waterproofing the pack and lining it or bagging items inside, so sleeping kit, spare clothing, and food stay dry even when the outside of the pack is soaked. Keep moving the big muscles, or at least the toes, fingers, and feet, when cold and still, to hold warmth in. A soldier who manages their layers, keeps a dry set back, keeps their kit dry, and rests under shelter stays warm and effective through a long wet night; one who does none of it is the casualty the section must warm up and bring in.

Sleep and rest discipline

Tiredness is not a minor discomfort; it erodes judgement, slows reactions, ruins footing, and on a long task makes a soldier a danger to themselves and a drag on the section. So sleep and rest are managed as deliberately as water and food.

The rule is to sleep when you can, not when you feel you have earned it. Take rest in the gaps the task offers, and learn to drop off quickly and to take short naps, expecting to need a minute or two to come fully awake afterwards. Where a hard task or a sleepless night is coming, bank sleep beforehand rather than arriving at it already spent. Within the section, sleep is shared and rotated, like every other part of the routine: some rest while others watch, in turn, so everyone gets some sleep and the position is never left unguarded. No soldier sleeps soundly while the whole section is meant to be alert, and no soldier is left on watch so long that they fade.

Rest is made worth having by the drills already taught: a soldier who has eaten, drunk, dried out, tended their feet, and rigged shelter sleeps warm and recovers, while one who lies down cold, wet, and hungry passes a miserable night and rises no better than they lay down. When sleep is genuinely short, soften the effects: take brief stretch breaks, keep the mind engaged, double-check anything important rather than trusting a tired memory, and treat strange things half-seen in exhaustion with suspicion before acting on them. The well-rested soldier is the one still thinking clearly when the careless one is making the mistakes tiredness breeds.

Care of kit and weapon

A soldier's kit and weapon are their means of working and surviving, and these too are kept serviceable: everything clean, dry, working, and stowed so that anything can be found, even in the dark and in haste.

The weapon is kept clean, dry, and functioning, cleaned in the field routine before fouling, grit, or damp can disable it, because a weapon that fails is no use at the moment it is needed; its care is a fixed part of every halt that allows it. Kit is kept dry where it must stay dry, protected in waterproof bags within the pack, and above all stowed in its known place, the same item in the same pouch every time, so a soldier can lay a hand on any item by feel, in the dark, without a light. This is not tidiness for its own sake; it is what lets a soldier work at night and move in a hurry without losing or fumbling for what they need.

The load is packed and ready: organised so what is needed first is reached first, what is needed in a hurry is to hand, and the weight rides well for the march. After every halt the drill is to account for kit and leave nothing behind, because an item left at a halt is an item gone, and a piece of kit dropped on the ground is also a sign left for anyone who passes. A soldier who finishes a task with kit dry, complete, and in order, and a weapon clean and working, is ready for the next without delay. The fuller treatment of equipment, packing, and the soldier's load is carried in the Basic Training Manual's logistics module.

Drawing the course together

This lesson, and this course, end where they began: with the field as the soldier's workplace, and with the plain skills that let a soldier work there. The course built two halves that meet in the field. Navigation, in the earlier lessons, taught a soldier to know where they are and find their way to where they must be, by map and compass and the reading of the ground, so they are never wholly lost. Fieldcraft, in the later lessons, taught a soldier to conceal themselves and use the ground, to observe and judge and indicate, to move from cover to cover under sound discipline, and, in this lesson, to live in the field while staying fit to continue. The soldier who has all of it, who navigates to and across the ground, who uses fieldcraft to operate on it unseen when they must be, and who lives well in the field so as to stay effective over time, is the soldier who can be sent into hard country and trusted to arrive, to work, and to come back.

For the Royal Kaharagian Army those tasks are, above all, search and rescue, exercises, and humanitarian field work: finding a lost walker on the high ground through a long cold night, working a flooded valley or a fire line for days, training hard across country, and helping nationals in their worst hours and conditions. Every one asks a soldier to navigate to and across difficult ground, to operate on it with sound fieldcraft, and to live in it long enough and well enough to finish the job. The soldier who can do all three is a searcher who finds the lost rather than joining them, a worker who lasts the deployment rather than falling out of it. These are not glamorous skills, and they were never meant to be. They are the reliable foundation on which everything else the soldier does in the field is built.

That foundation is laid in knowledge, in these lessons, but it is made real on the ground and certified in person. Take what you have learned onto real terrain, with a real map and compass, in real weather, under instruction, and build the skills until they hold without thought, then keep them current, because skills fade and the ground forgives nothing. Do that, and when the call comes, to the high ground, the flood, the fire line, you will be what the work needs and what the lost most hope for: a soldier who can find the way, work the ground, and last the distance.

In Practice: The Searcher Who Lasted the Night

A section is out on the high ground through a long, wet winter night, searching for a missing walker alongside the civil rescue service, and the search may run until dawn. Living in the field decides who is still useful when the light comes. The disciplined soldier ran the field routine from the start: at the first halt they changed into dry socks, ate from their rations though they were not hungry, drank before they were thirsty, and pulled on a layer before the chill of standing set in, while a comrade rigged a shelter sheet, low and out of the wind on a slight rise, for the section to rotate through and warm up in turn. They felt a hot spot forming early and stopped at once to cover it rather than marching on, so their feet held. They washed their hands before eating, kept their dry set sealed and untouched in its bag, and topped up and treated their water from a hill stream the moment the bottles ran low rather than waiting until they were dry. Their kit stayed dry and ordered, found by hand in the dark, and at dusk they had stowed everything for the night so nothing was lost. Hours later, in the cold and dark, they are still searching, warm enough, fed, sure-footed, and clear-headed enough to read the ground and keep track of where they are. The soldier who skipped all of it to save effort is by now chilled, blistered, soaked through their one wet set, and spent, fallen out of the search and become the second casualty the others must bring down. The work the RKA is most often called to do is exactly this, long, cold, and hard, and it is field living that decides who finishes it.

Check Your Understanding

1. Explain the principle that "a soldier who does not look after themselves becomes a casualty", and why this lesson calls field living a discipline rather than a comfort. In the field routine, why is personal administration done in turn within the section rather than all at once, and what are the dawn and dusk stand-to routines for?
2. Set out the three parts of water discipline, drinking enough, rationing and refilling, and treating doubtful water, and describe the drill for treating water with purification tablets. Why must a soldier in cold weather drink deliberately rather than by thirst, and where is the fuller water and hygiene drill taught?
3. Why is foot care given first place among the field-living drills, and what is the full drill for boots, socks, and hot spots? When siting and pitching a basha, what makes a good site, and why does insulation from the ground matter as much as the cover overhead?

Reflection (write a short paragraph): This capstone says the soldier who navigates, uses fieldcraft, and lives well in the field is effective for the long haul, which is what the RKA's search-and-rescue, exercise, and humanitarian tasks demand. Think back across the whole course and choose one real field task. Describe how navigation, fieldcraft, and field living would together decide whether a soldier finished that task as a help or fell out of it as a second casualty, and what that tells you about why these plain skills, mastered on the ground, are worth taking seriously.

Summary

• A soldier who neglects themselves becomes a casualty and a burden, so field living is a discipline of effectiveness, not a comfort; small neglects accumulate into casualties that take a section apart without a shot fired.
• The field routine runs as a daily cycle balancing task, rest, food, and maintenance; personal administration is done in a fixed order of priority and in turn within the section so security and rest are both kept, with a full stand-to at dawn and dusk.
• Water discipline has three parts: drink enough and ahead of thirst (deliberately in the cold), ration and refill at every chance, and treat all field water before drinking, by the issued tablets with their full waiting time or by boiling; the dangers are dehydration and waterborne illness, with the fuller drill in the Field Health, Hygiene and Sanitation course.
• Eat enough from rations even when tired, and more in the cold because energy keeps the body warm; cook with discipline, keep rations sound and inspect tins and packets, and carry all rubbish out to stay healthy and concealed.
• Foot care comes first: well-fitted, broken-in boots, clean dry socks changed and aired whenever the chance comes, hot spots covered the moment they are felt, and the feet washed and dried; personal hygiene means washing the parts that matter, the teeth, and above all the hands before food and after the latrine.
• Shelter is a low, well-sited basha out of the wind and off wet ground, with insulation beneath the body; staying warm and dry means clothing discipline (layer up and down, keep a dry set back) and keeping kit dry, with cold and heat injury covered by Combat First Aid and severe cold by Cold-Weather Operations and Survival.
• Sleep and rest are shared and rotated and taken when they can be, kit and weapon are kept serviceable, dry, and stowed in known places with the load packed and ready, and nothing is left behind at a halt.
• The course closes on its purpose: the soldier who navigates, uses fieldcraft, and lives well in the field is effective for the long haul, which is exactly what the RKA's search-and-rescue, exercise, and humanitarian field tasks demand. The knowledge is laid here; the skills are built on the ground, under instruction, certified in person, and kept current.
