An IFAK, or Individual First Aid Kit, is a small personal trauma kit carried on the body. It is built for the first minutes after a serious injury, before professional help arrives. In the words of the US Army, it targets the two leading causes of preventable death on the battlefield: severe bleeding and a blocked airway. That focus is what separates an IFAK kit from an ordinary first aid kit.
Below: where the IFAK came from, how it differs from a standard first aid kit, what goes inside, how to carry it, and how to make sure it works when you need it.
What IFAK Stands For and Where It Came From
IFAK is usually read as Individual First Aid Kit. In the US Army it officially stood for Improved First Aid Kit, because it replaced the single trauma bandage that was often the only first aid item soldiers carried before. Both names describe the same idea: a kit each person carries for self-aid or for treating a buddy.
The Army introduced the IFAK in the early 2000s and issued it to every deploying soldier through its Rapid Fielding Initiative. The original kit weighed about one pound and was packed in a modified MOLLE pouch; more than 900,000 were fielded. The Army stated its purpose plainly: to let soldiers provide self-aid and buddy-aid against severe hemorrhage and inadequate airway. A revised IFAK II followed in the 2010s.
The contents follow Tactical Combat Casualty Care (TCCC), the US military's standard for treating injuries under threat. Its logic is simple: fix what kills fastest, first.
From the military, the IFAK spread to police, security teams, shooters, hunters and anyone working or travelling far from fast medical help.
IFAK vs a Regular First Aid Kit
A regular first aid kit is for the injuries you are most likely to get: cuts, blisters, burns, headaches. An IFAK is for the injuries most likely to kill you if nothing is done in the next few minutes. The two overlap very little.

Related terms you will see: AFAK and MFAK usually mean larger kits for a vehicle or team, and "trauma kit" is the broad category, of which the IFAK is the personal, on-body version.
The practical takeaway: an IFAK does not replace a regular first aid kit. Most people who carry one also keep a basic kit for everything else.
What Is in an IFAK?
IFAK contents are chosen by priority, not by variety. TCCC uses the MARCH sequence, which ranks the threats to life in the order they kill:
- M — Massive hemorrhage: severe bleeding
- A — Airway: a blocked or compromised airway
- R — Respiration: chest injuries that stop effective breathing
- C — Circulation: shock and further blood loss
- H — Hypothermia and head injury: heat loss, which worsens bleeding, and head trauma
Each item in a well-built IFAK maps to one of those letters:
|

What it is for |
MARCH |

Tourniquet |
Stopping life-threatening bleeding from an arm or leg |
M |

Hemostatic gauze |
Packing wounds where a tourniquet cannot go, such as the groin, armpit or neck |

|
Pressure (emergency) bandage |
Holding pressure on a wound and keeping dressing in place |

The Army's own kit. The US Army's IFAK II is a useful reference point. Its component lists include two one-handed tourniquets, hemostatic gauze, compressed gauze, an elastic bandage, a nasopharyngeal airway, a chest seal, an eye shield, a strap cutter, gloves, tape, a marker and a casualty card.
Carry what you are trained to use. A tourniquet, gauze and a pressure bandage can be learned in a short course. An airway adjunct and a chest seal need proper instruction before they belong in your kit. An item you cannot use only adds weight.
Ready-made or built yourself? A pre-packed IFAK is quick and usually laid out logically, but it may include items you have not trained on or brands you would not choose. Building your own means buying a pouch and filling it with exactly the supplies you know how to use, from sources you trust. Either way, check every item against the next two sections before relying on it.
What Is an IFAK Pouch and Where Should It Go?
An IFAK pouch is the carrier for the kit, not the kit itself. It holds the supplies in a fixed layout and attaches to your gear, usually by MOLLE straps, so it stays in the same place every time you reach for it.
Common designs:
- Rip-away. A base panel stays on your gear and the pouch tears off it in one pull, so you can open it in your lap or hand it to someone else.
- Roll-out or clamshell. The pouch opens flat, so every item is visible at once.
- Horizontal or vertical. Horizontal pouches suit the back of a belt or the bottom of a carrier; vertical ones fit the side of a carrier or a pack strap.
Inside, elastic loops and sleeves keep each item in its slot, so you can find it by feel.
Where to put it:
- Reachable with either hand. You may have to use it one-handed, or on your own injured side.
- Marked. A red cross or a red pull tab tells anyone helping you where your kit is.
- Tourniquet first. Keep at least one tourniquet where it can be reached fastest, often in its own pouch on the outside of the kit or on the belt, not buried at the bottom.
- On the body, not in the bag. A kit in a pack you have dropped is no help.
Common spots are the back or side of a battle belt, the side or bottom of a plate carrier, and a pack shoulder strap. How the pouch attaches to webbing is explained in What Is MOLLE?
Our IFAK pouches use rip-away bases and MOLLE attachment, and are sold empty, so you fill them with the supplies you are trained on. Separate tourniquet pouches keep a tourniquet outside the main kit for the fastest reach. If you want the tourniquet ready to go, the FamTac Tourniquet Kit pairs a MOLLE tourniquet pouch with a CAT Gen 7 tourniquet and a waterproof marker for noting the application time.
Before You Rely on It: Genuine Parts, Expiry Dates and Training
An IFAK only works if what is inside is genuine, in date and in trained hands.
Genuine tourniquets. The Committee on Tactical Combat Casualty Care (CoTCCC) maintains a list of recommended limb tourniquets, including the CAT, the SOFTT-W and the SAM-XT. Note the wording: the committee recommends devices; it does not "approve" or "certify" them, so treat those words on a listing with caution. Counterfeit tourniquets are widely sold on online marketplaces. They look right but can break under load, and a tourniquet that fails is worse than none. A price far below the authorised retailers' is the clearest warning sign; buy from the manufacturer or its listed dealers.
Expiry dates. Sterile dressings, hemostatic gauze and some airway items carry expiry dates. Heat, cold and repeated handling also wear packaging and tourniquet straps. Check the kit on a schedule, for example every few months and after every field trip, and replace anything out of date, opened or damaged.
Training. The contents are only as useful as your ability to use them under stress. Stop the Bleed courses teach tourniquet use, wound packing and pressure in a few hours and are open to anyone. TCCC courses go further for people whose work puts them at risk. Train with the same tourniquet you carry, so the first time you apply it is not the time it matters.
FAQ
Can you use an IFAK for minor cuts and blisters? Better not. Every item you take out for a minor injury is one that may be missing when a serious one happens, and opened packaging degrades sterile supplies. Keep a regular first aid kit for everyday knocks and leave the IFAK sealed for trauma.
Should everyone on a team carry the same IFAK? Ideally, yes, or at least carry it in the same place with the same layout. When someone treats you, they will use your kit, not theirs, so a standard location and layout let them find the tourniquet or gauze without searching.
