Ask a paramedic what their kit lives in and you get a bag. Ask a combat medic in Ukraine the same question in 2026 and you get a longer answer: a bag on the back for the first ten metres, a hard case in the vehicle, a hard case at the stabilisation point, a hard case in the cellar where the stabilisation point moved after the last one was hit, and a strong opinion about which of those cases were still dry and still closed after the winter. This article is that longer answer, written for the people who buy and pack medical kit: ambulance services, fire brigades, industrial rescue teams, expedition medics, tactical medics, and the NGOs and volunteers who have spent four years learning, at cost, what works. 🩺
It is not an argument that bags are wrong. Bags are the right tool for the first minutes and the last metres, and every medic here says so. It is about the nine things practitioners say when the question is asked properly, about what the Ukrainian evacuation chain has changed in the answer, and about how water, humidity, blast and speed decide which container carries which part of the kit. The sourcing is field assessments of Ukrainian medical evacuation published in 2025 (a Norwegian embedded report, the US Army's Center for Army Lessons Learned, CEPA, Breaking Defense), interviews with Ukrainian and volunteer medics in RFE/RL and elsewhere, WHO's reporting on attacks on Ukrainian health care, and what our own customers in evacuation units and stabilisation points tell us when they order. We wrote about the medical lessons themselves in no golden hour: 12 lessons from Ukraine's battlefield medicine; this is the container side of the same story.
Part 1: What changed the question
The golden hour is gone, so the kit waits with the casualty
In every war before this one, the model was to stabilise and move: tourniquet, airway, and a vehicle or helicopter within an hour. In Ukraine the drones over the evacuation routes have made that impossible on most of the front. Wounded soldiers wait hours, sometimes days, in a dugout or a cellar before a vehicle or an unmanned ground vehicle can reach them, and the medic on the spot practises what the doctrine now calls prolonged field care with whatever is in reach. The kit that used to be for ten minutes of use is now for a night, in the damp, in the dark, and then it has to survive the ride out. That is a different container problem.
The stabilisation point is the new emergency department, and it moves
Ukraine built a network of stabilisation points a few kilometres behind the line: a cellar, a school basement, a repurposed Soviet shelter, staffed by a surgeon and a handful of medics, where the wounded arrive from the field and are kept alive until the hospital run. They are targeted, so they move; the US Army's lessons-learned paper on the Ukrainian model describes them as decentralised and underground for exactly that reason, and WHO counted a 20 percent rise in attacks on Ukrainian health care in 2025. A stabilisation point's stock therefore has to be packable in minutes, survive a move on a truck over a shelled road, and set up again in a room with no shelves. That is a container problem too, and it is where hard cases replaced boxes and bags within the first year.
Blast is the injury, and blast is also the environment
Most of the wounded at Ukrainian stabilisation points have blast injuries from mines, artillery and drones. The same blast that makes the patient is what the medic's kit sits in: overpressure, fragments, debris, and being thrown. A bag hit by fragments spills its contents; a case hit by fragments is usually scratched. Medics who have had a vehicle hit describe what they found afterwards, and it is the difference between a kit that was still usable and one that was not.
Water and damp are the slow enemy
Dugouts flood. Cellars sweat. Vehicles leak. Winter in Ukraine means everything in a bag is damp by February, and damp is what ruins sterile packaging, corrodes instruments, kills batteries in monitors and pumps, and grows mould in dressings. Medics hang washed tourniquets on cellar walls to dry because they are reusing single-use devices; they do not have the luxury of losing a case of gauze to mildew. Sealed cases with a desiccant pack are how the stock at a stabilisation point stays usable through a winter, and every experienced volunteer group ships that way now.
Part 2: Nine things medics say about bags and hard cases
1. The first-line kit is on the body, and it is a bag
Nobody carries a hard case to a casualty under fire. The individual kit is on the medic's chest or back: tourniquets, haemostatic gauze, chest seals, a nasal airway, gloves, in a pouch or a small backpack that can be opened one-handed. Every medic says the same: the first-line kit is soft, fast and worn. Hard cases begin one step back, where the vehicle is, where the stabilisation point is, where the stock is. The mistake is not choosing a bag for the first line; it is choosing a bag for everything after it.
2. The vehicle kit gets thrown, soaked and sat on, and a bag does not survive that
The evacuation vehicle in Ukraine is a pickup, a van, an armoured ambulance or, increasingly, an unmanned ground vehicle, on roads that are cratered and under drone observation, driven fast in the dark. The kit in the back is thrown against the sides, flooded from the floor, sat on by a stretcher, and occasionally hit. Medics who started the war with bags in vehicles describe opening them to find monitors cracked, drugs crushed, fluids leaking and sterile packs soaked. The vehicle kit went into hard cases within months: a sealed case with cut foam for the monitor, the suction and the oxygen regulator; a dividers case for the dressings and drugs; a case for fluids that can be strapped to the floor. It is not a doctrine; it is what was left after the first bad night.
3. Moisture kills more stock than fragments do
This is the quiet one. A fragment hit is dramatic and rare; a damp winter is certain. Sterile packaging that has been wet is not sterile. Electrodes that have absorbed moisture do not stick. Lithium batteries in a pulse oximeter or a portable ultrasound that have sat in a damp bag are dead when they are needed. Instruments rust. Medics at stabilisation points describe stock losses to damp in the first winter that were larger than losses to anything else, and the answer was sealed cases with desiccant, opened only to restock, with the working stock in a separate case that is opened daily. A case with an O-ring and a pressure valve is not a luxury in a cellar; it is the shelf that keeps the shelf dry.
4. Speed of evacuation means the case must move as one lift
When a stabilisation point is warned, it moves in minutes. Everything that is in cases goes on the truck as it is; everything that is on shelves or in bags has to be packed, and it is the packing that is left behind. Medics describe the discipline that emerged: the stabilisation point's stock lives in a fixed set of cases with a fixed layout, the cases are closed between uses, and a move is a matter of carrying them out. A hard case with wheels and a handle moves 30 kilograms of stock with one person; the same stock in bags needs three trips. In a fast evacuation the difference is whether the stock arrives at the new site at all.
5. Blast protection is about what is inside staying where it is
A case that is thrown by an overpressure wave, or a vehicle that is hit, does two things to the kit inside: it throws it and it crushes it. Cut foam holds the monitor, the ultrasound, the suction unit and the drug ampoules in place so they do not become projectiles inside the case; a rigid shell takes the crush so the contents do not. Ukrainian medics describe cases found after a strike with the shell scarred and the contents intact, and bags found with the contents scattered and glass broken. A fragment through a polymer shell is possible; a fragment through a polymer shell that also breaks the equipment inside foam is much less so. No case is armour, and none is sold as such; the point is that the shell and the foam absorb what a bag transmits.
6. The layout has to work in the dark, by a stranger
Stabilisation points work at night with the lights low, and the person opening the case may not be the person who packed it: a new medic, a volunteer, a surgeon rotated in. Cut foam with labelled cavities, or dividers with printed labels, means the tourniquet is where the tourniquet always is and the empty cavity says what is missing. A bag with pockets means searching. Every medic interviewed on the subject says some version of the same thing: standardise the layout, label it, and never change it without telling everyone. A case makes that possible because the layout is physical; a bag makes it a matter of habit.
7. Drugs and controlled items need a lockable, countable container
Analgesics, sedatives and the drugs of prolonged field care are controlled, counted and signed for. At a stabilisation point they live in a lockable case with a cut-foam layout that shows the count at a glance, and the case goes back on the truck locked. A bag with a zip is neither lockable nor countable. This is also the rule in every European ambulance service and the reason drug cases in ambulances have been hard cases for decades; Ukraine simply confirmed it under harder conditions.
8. The case is also the table, the seat and the step
In a cellar with no furniture, the closed case is the table the drugs are drawn up on, the seat the medic sits on for a night, the step to reach the shelf, and the platform the monitor sits on at the right height. Medics mention this without prompting. A hard case that takes a person's weight closed is a piece of furniture at a stabilisation point; a bag is not. Peli's larger cases are rated for that and used for it.
9. It has to outlast the rotation, and the war
Stock is replaced weekly; equipment is replaced when it breaks; the case is replaced never. Volunteer groups that have supplied Ukrainian medics since 2022 describe cases they shipped in the first year still in service at their fourth stabilisation point, with a latch replaced and new foam. Bags from the same shipments are gone. The case is the one part of the medical kit that is bought once, and it is the part that keeps the rest of it dry, findable and intact through everything above.
EMS cases with organisers and dividers
Part 3: Water, humidity and blast, taken seriously
Water: the rating and what it means for medical stock
A sealed case with an O-ring and an automatic pressure valve keeps water out at immersion for a stated time and depth, and keeps rain, spray and a flooded floor out indefinitely. For medical stock that means sterile packs stay sterile, dressings stay dry and drugs stay in date. The rating is on the case; the discipline is in closing it. A sealed case left open in a wet cellar is a bag. We explained the ratings in waterproof, water-resistant or submersible.
Humidity: desiccant, rotation and the two-case rule
A sealed case keeps humidity out and also keeps it in: stock packed damp stays damp. The rule that emerged at Ukrainian stabilisation points is two cases per category: a reserve case, sealed with a desiccant pack, opened only to restock the working case; and the working case, opened daily and repacked from the reserve. The desiccant is checked at each restock. Electronics (monitor, oximeter, ultrasound, pump) live in cut foam in their own sealed case with a desiccant, batteries at partial charge, and come indoors when the point has an indoors. The instruments are dried before they go back in. This sounds fussy and it is what stopped the stock losses.
Cold: the other humidity problem
A case brought from a minus-fifteen truck into a heated cellar sweats inside as the air condenses. Open it and let it equalise before restocking, or keep the reserve cases in the cold and the working case in the warm. Fluids freeze; a fluids case in a vehicle in winter needs insulation and a heat pack, and the fluids are the one thing medics wrap in soft insulation inside the hard case.
Blast: foam, shell and what is not promised
Cut foam of the right density holds each item so it cannot move; a rigid shell distributes crush and takes the scratches. Neither stops a direct fragment, and a case is not ballistic protection and should not be described as one. What the combination does is turn most overpressure and debris events into a scarred case with a working kit inside. Medics who want more put the cases low in the vehicle, behind the axle, strapped, and the drugs and electronics in the smallest cases furthest from the sides.
Contamination: the case that can be washed
A polymer case that has been in a room with a mass-casualty event is hosed down, disinfected and dried in an hour. A fabric bag that has absorbed blood is finished. This is a hygiene argument as much as a durability one, and it is the reason hospital and ambulance services in Europe standardised on hard cases for drug and equipment kits long before Ukraine.
Part 4: The layouts that work
The vehicle kit
A 1600-size case with an EMS organiser in the lid (airway, chest seals, haemostatics, tourniquets in the lid pockets, visible on opening) and dividers in the base for dressings, splints and fluids. A 1500-size case with cut foam for the monitor, suction and oxygen regulator. A 1400-size case with cut foam for the controlled drugs, lockable. Fluids in a dividers case strapped to the floor. All labelled, all strapped, all closed when not in use.
The stabilisation point
Reserve stock in sealed wheeled cases (1620, 1650, 0550 trunks) by category, with desiccant, opened only to restock. Working stock in EMS cases on the floor or on a trunk used as a table. Electronics in cut foam, indoors. Drug cases locked. A medical chest with drawers for the surgical set if the point runs a surgeon. A move is: close everything, carry it out, strap it, drive.
The expedition or industrial medic
The same principle at a smaller scale: a worn first-line pouch, a 1465- or 1500-size EMS case in the vehicle or at base, cut foam for the electronics, dividers for the consumables, a small locked case for drugs, and a desiccant in each. The difference from Ukraine is that nobody is shooting at it; the water, damp, crush and speed are the same.
The ambulance service
European ambulance services have run hard cases for drug and equipment kits for decades and bags for the grab kit; Ukraine's contribution is the stabilisation-point layout for prolonged care and the discipline about damp. Services that are building mass-casualty or civil-defence stocks after the events of the last two years are ordering the Ukrainian layout: reserve in sealed cases, working in EMS cases, electronics in foam, everything movable in one lift.
Chests and trunks for stabilisation-point stock
Part 5: Specifying a medical case fleet
Start from the chain, not the catalogue
First line worn, vehicle, base or stabilisation point, hospital run. Each link has a container: pouch, vehicle cases, reserve and working cases, transfer case. List what is used at each link and how often it is opened; the opened-daily items go in the working cases, the rest in sealed reserve.
Organiser, dividers or foam
Lid organiser for the items that must be visible on opening. Dividers for consumables that change count. Cut foam for anything electronic, glass or controlled. One case can carry all three.
Colour, label, seal
One colour per category (airway, haemorrhage, drugs, electronics, fluids); a laminated contents list in the lid; a tamper seal on the reserve cases so a broken seal means a restock is due. The empty cavity is the inventory system.
Weight and lift
Nothing over what one person lifts into a truck. Wheels on anything over 20 kilograms. Handles on both ends of the large cases so two people can carry a loaded trunk down cellar stairs.
Desiccant and inspection
A desiccant pack in every sealed case, checked at every restock. A monthly inspection of seals, latches and wheels, because a case that no longer seals is the bag problem again.
Part 6: Seven mistakes in medical kit containers
Bags for the vehicle kit
Crushed monitors, soaked packs, leaking fluids. Cases from the first day.
One case for everything
Opened for a plaster, closed wet, the drugs and the electronics share the damp. Working and reserve separated; electronics on their own.
No desiccant
A sealed case holds the damp in. Desiccant in every reserve case, checked.
Layout that changes with the medic
The night shift cannot find the tourniquet. Fixed layout, labelled, laminated list.
Drugs in an unlocked container
Not countable, not defensible. Locked foam case.
Cases too heavy to move in one lift
Left behind at the evacuation. Under the one-person limit or on wheels.
Describing a case as protection against fragments
It is not. It keeps the kit together and dry through most blast and debris events, and that is what it is for.
Frequently asked questions
Should the first-line kit be a hard case?
No. It is worn, opened one-handed under fire, and is a pouch or small pack. Hard cases start at the vehicle.
What size case for a vehicle medical kit?
A 1600-class EMS case for the main kit, a 1500-class for electronics in foam, a 1400-class locked for drugs, a dividers case for fluids. Adjust to the vehicle and the protocol.
How do we keep stock dry at a base or stabilisation point?
Sealed reserve cases with desiccant, opened only to restock a separate working case; electronics in foam in their own sealed case, indoors; instruments dried before storage.
Are Peli cases blast-proof?
No case is, and none is sold as such. A sealed polymer shell with cut foam keeps the contents in place and intact through overpressure, debris and crush events that destroy a bag; it does not stop fragments.
Can the cases be decontaminated?
Yes; polymer shells and closed-cell foam are washed and disinfected, and the EMS organisers are removable. Open-cell foam is replaced.
What do Ukrainian medics actually order?
EMS cases with organisers for the vehicle and working stock, large wheeled cases and trunks for reserve, foam-cut cases for monitors and ultrasound, locked cases for drugs, desiccant by the box, and spare latches. The layouts above are theirs.

The short version
Bags for the first ten metres; hard cases for everything after. Ukraine's evacuation chain, with its hours of waiting, its moving stabilisation points, its flooded cellars and its blast, turned that from a preference into a rule: sealed cases with foam and desiccant keep the monitors working, the packs sterile, the drugs counted and the stock movable in one lift when the point has to go. Buy the chain, not the catalogue, and the case will outlast the war it was bought for. 🩺
If you are specifying medical cases for an ambulance, a rescue team, a stabilisation point or a volunteer shipment, send us the kit list and the vehicle. We will propose the case set, cut the foam for the electronics and quote it as one order.
