Treating a Gunshot Wound in the Field: Tourniquet and Wound Packing That Actually Saves Lives

It was a training exercise in the Cascade foothills, 2009. One of my most experienced students — a guy with twelve years of hunting and two combat deployments — took a simulated casualty hit to the upper thigh during a force-on-force drill. We called it real for training purposes. He froze for six seconds. Six seconds doesn't sound like much until you understand that a femoral artery bleed can drop a person unconscious in under two minutes. When I debriefed him afterward, he said the same thing every frozen person says: I knew what to do, I just couldn't make my hands move. That's not a knowledge problem. That's a drilling problem. And that distinction is the entire reason I'm writing this.

Gunshot wounds are not clean. They are not like the movies. There is no slow dramatic collapse. There is heat, chaos, screaming, and blood — more blood than most people have ever seen outside of a slaughterhouse. The physiology is brutal: a high-velocity round doesn't just punch a hole, it creates a temporary cavity, destroying tissue in a radius far wider than the entry wound. A wound to a major vessel — femoral, brachial, subclavian — is a countdown clock that starts the moment it happens. You have a narrow window to act and zero margin for confusion. What I'm going to walk you through here is the exact protocol I've taught to Rangers, to search and rescue teams, and to civilians on my homestead who want to be capable human beings. Pay attention.

The Mistake Most People Make

The biggest mistake I see — and I mean the single most dangerous, most common error across every training cohort I've worked with — is what I call the pressure myth. People believe that holding direct pressure on a gunshot wound is the first and most important step. They've seen it in movies. They've read it in outdated first aid manuals written for car accidents and kitchen cuts. They clamp their hands on the wound, lean in, and count to ten like they're waiting for a pie to cool. Meanwhile, the casualty's pressure is crashing.

Direct pressure on a gunshot wound to an extremity is not the primary intervention. A tourniquet is. The TCCC — Tactical Combat Casualty Care — protocol, which is the gold standard developed from real combat data, is explicit: for extremity hemorrhage that is life-threatening, you apply a tourniquet first, ask questions later. The mindset shift required here is enormous for civilians because we're trained from childhood that tourniquets are dangerous, that they cause limb loss, that they're a last resort. That is outdated thinking rooted in World War I-era medicine. Modern tourniquet data from Iraq and Afghanistan is unambiguous — properly applied tourniquets save limbs and lives. The hesitation to use one is what costs limbs.

The second version of this mistake is the half-tourniquet — someone cinches it just tight enough to slow the bleed but not stop it. This is actually worse than no tourniquet at all. A partial occlusion restricts venous return without stopping arterial flow, which accelerates blood loss. If you're going to put on a tourniquet, you tighten it until the bleeding stops, full stop. That means it's going to hurt. The casualty will tell you to stop. You don't stop.

The Fundamentals — Step by Step

1. Scene safety and your own assessment first. I know this sounds callous but if you go down trying to help someone, there are now two casualties. Assess your environment for continued threat before you expose yourself. This takes three seconds, not three minutes. Move the casualty behind cover if you can do so without additional injury risk.
2. Identify the bleed type and location immediately. Extremity wound — arms or legs? Go straight to tourniquet. Junctional wound — groin, armpit, neck, or pelvis where a tourniquet can't go? You're going to wound packing. Torso wound? Wound packing and rapid evacuation — there is no field fix for internal abdominal or thoracic hemorrhage. Chest wounds with sucking sound require a chest seal, which is a separate protocol.
3. Tourniquet application for extremity bleeds. Place the tourniquet 2 to 3 inches above the wound — not on the joint, never on the joint. The CAT (Combat Application Tourniquet) Gen 7 is the standard. Route the tail through the buckle, pull it tight, secure the hook-and-loop, then windlass until bleeding stops. Count your windlass turns. Lock it down with the clip. Write the time of application on the tourniquet or on the casualty's forehead in marker. Time matters for the receiving medical team.
4. Confirm hemorrhage control. Look at the wound. Is it still actively bleeding? If yes, tighten further or apply a second tourniquet immediately proximal to the first. Never assume it's working — confirm visually.
5. Wound packing for junctional or through-and-through wounds. This is the step that causes the most hesitation. You must physically pack the wound cavity with hemostatic gauze. I'm talking about putting your gloved fingers — or a finger if that's all you have — into the wound and packing gauze directly against the source of the bleed. Hesitation here is lethal. Use Combat Gauze (QuikClot brand) or Celox Gauze — these are impregnated with kaolin or chitosan respectively, which accelerate clotting chemistry at the wound site.
6. Apply direct pressure after packing — hard, sustained, timed. Once the wound is packed, apply hard direct pressure for a minimum of three minutes for standard gauze, or three minutes for QuikClot Combat Gauze. Set a timer. Most people under stress undercount by 40 to 60 percent. Three minutes of sustained, bodyweight pressure feels like an eternity when someone is screaming. Hold the count anyway.
7. Secure and reassess. Apply a pressure bandage — an Israeli bandage (also called an Emergency Bandage) works well here — over the packed wound to maintain pressure without requiring you to hold it manually. Reassess the casualty's mental status, airway, and circulation. Are they responsive? Breathing? Are the lips turning blue? Treat for shock: lay flat, elevate legs if no spinal injury is suspected, prevent heat loss with a mylar blanket.
8. Communicate and evacuate. Field medicine buys time. It does not replace surgery, blood products, or hospital-level care. Your job is to stop the bleed, maintain airway, treat for shock, and get that person to definitive care as fast as humanly possible. Call 911 if you have signal. Know your grid coordinates. Have an evac plan before you need it.

What You Actually Need

• CAT Gen 7 Tourniquet (Combat Application Tourniquet) — Under $30 per unit, buy from a verified supplier like North American Rescue or Rescue Essentials. Do not buy a counterfeit CAT from an unnamed Amazon seller — the windlass rod on knockoffs fails under real tension and people have bled out because of it. I carry two on my person during any field operation and have them staged in every vehicle and structure on my property.
• QuikClot Combat Gauze or Celox Gauze — Under $30 per package. These are the hemostatic dressings recommended by the Committee on Tactical Combat Casualty Care. Regular gauze will not do what these do — the kaolin in QuikClot activates the clotting cascade at the wound site. Celox uses chitosan which works independently of the clotting cascade, making it preferable for casualties on blood thinners. Know which you have and why.
• Israeli Emergency Bandage (6-inch) — Under $10 each. This is the pressure bandage you apply over packed wounds to free up your hands. The built-in pressure applicator bar and self-securing closure make it genuinely one-handed capable. I've used these on livestock and on people. They work. Buy six minimum, stage them with your tourniquets.
• North American Rescue (NAR) Individual First Aid Kit (IFAK) — Under $100 fully kitted. A quality IFAK pouch with CAT, Combat Gauze, Israeli bandage, nitrile gloves, chest seals, and a nasopharyngeal airway is what I issue to every person on my property. The NAR M-FAK Mini First Aid Kit runs around $55 to $65 and is a solid starting point. This is not the place to cut costs.
• Nitrile gloves, multiple pairs — Under $15 for a box of 100. Blood-borne pathogens are real. Gloves go on before you touch any wound, no exceptions. Keep four pairs in every kit because gloves tear, gloves get contaminated, and you may need to re-glove mid-treatment.
• Permanent marker — Under $5. You need to write tourniquet application time on the casualty. Surgeons and trauma teams need this information. A Sharpie in your kit is not optional — it is life-critical data transmission.

Advanced Tactics — What Separates Survivors

Drill it until your hands know it without your brain. In training, I've seen medics who could recite the MARCH protocol — Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia — perfectly in a classroom setting completely lock up when a training dummy was sprayed with red dye and someone was yelling. Cognitive load under stress is brutal. The solution is repetition under realistic conditions. I run quarterly trauma lanes on my property. Blindfolded tourniquet application. Timed wound packing on a realistic wound trainer. Your hands need to know this like you know your own name.

Treat through clothing when necessary. The one thing that changed everything for me operationally was accepting that cutting through clothing to expose a wound before tourniquet application is sometimes a luxury you don't have. A tourniquet applied over a single layer of clothing works. It is not ideal. It is far better than the alternative. Learn to feel your landmarks through fabric and apply the device. You can cut clothing away after the bleeding is controlled.

The psychological component of the casualty is real and must be managed. In training, I watched a student stop packing a wound because the simulated casualty grabbed his wrist and said stop. In a real scenario that instinct to comply can kill. Talk to your casualty constantly. Tell them what you're doing and why. Say: I know this hurts, I know you want me to stop, I need you to squeeze my arm and stay with me. Giving them a physical task keeps their brain engaged and reduces their thrash response. This sounds soft. It is actually tactical.

Know your junctional anatomy before you need it. The groin is the most common junctional bleed I've seen in training scenarios and the one people are least prepared to pack because there is no psychological preparation for putting your fist into someone's groin and pushing hard. The femoral artery runs along the medial thigh just below the inguinal ligament. Pack deep, pack hard, pack toward the bone. A junctional tourniquet like the SAM JT or the JETT can be used for groin wounds when wound packing alone isn't controlling the bleed. Know these devices exist. Have one in your kit.

Prevent hypothermia from minute one. Hemorrhagic shock and cold are a lethal combination. The coagulation cascade — the chemical process that forms clots — functions significantly less efficiently in a cold patient. Every degree of temperature drop matters. I always have a mylar emergency blanket in my IFAK. As soon as hemorrhage is controlled, the casualty goes under a blanket. This is not comfort care. This is hemorrhage control continuation.

Common Questions

Q: Can I use a belt or a bandana as a tourniquet if I don't have a CAT?
A: Yes, but understand the limitations. Improvised tourniquets are significantly less effective than purpose-built devices because they lack the mechanical advantage of a windlass system. If you must use a belt, you need it to be at least 1.5 inches wide, cinch it as tight as physically possible, and tie a stick through it to windlass it tighter. A phone charger cord or shoelace will not work — they're too narrow and will cause tissue damage without achieving vascular occlusion. The correct answer is: own a real tourniquet.

Q: How long can a tourniquet safely stay on before damage occurs?
A: The current TCCC guidance suggests that properly applied tourniquets can remain in place for up to two hours without causing permanent limb damage in most cases, and up to six hours with increasing risk. The old fear of tourniquet-caused amputation came largely from improper application — too narrow, too loose, left too long without medical follow-up. A well-applied CAT on a patient who reaches surgical care within two hours is extremely unlikely to result in limb loss. Leaving a hemorrhage uncontrolled for sixty seconds because you're afraid of the tourniquet will cause death. The math is not complicated.

Q: What if I only have regular gauze — no hemostatic gauze?
A: Pack it anyway. Standard gauze packed tightly against a wound source with sustained hard pressure can achieve hemorrhage control, particularly in conjunction with a tourniquet. It is slower, requires longer pressure hold time — think five to seven minutes — and is less effective in deep cavitary wounds, but it is far better than nothing. Cut gauze into strips if needed to get it deeper into the wound cavity. Any gauze packed hard against the bleeding point is better than gauze sitting loosely on top of the wound.

Q: Should I remove the tourniquet or packed gauze in the field to reassess the wound?
A: No. Do not remove a tourniquet once applied in a field environment unless you are a trained medical professional with IV access, blood products, and a controlled environment. Do not remove packed gauze — you will disrupt the clot that has been forming. Your job is to maintain what you've applied, prevent shock, and get to definitive care. Reassess circulation distal to the tourniquet — pulses below the device, capillary refill — but do not disturb the wound or the tourniquet.

Your Action Plan This Week

1. Order a genuine CAT Gen 7 tourniquet from North American Rescue (narescue.com) today. Budget $32. Verify the lot number and authentication code on the package. This is not the place to comparison shop on Amazon with unknown sellers.
2. Order QuikClot Combat Gauze or Celox Gauze, one pack of each. You'll learn which you prefer and you'll have both options staged. Rescue Essentials (rescue-essentials.com) carries both and ships fast.
3. Practice tourniquet application on yourself — your non-dominant arm — ten times this weekend. Time yourself. You should be able to apply it one-handed in under sixty seconds. If you can't, do it ten more times. Do not move on until you own this movement.
4. Take a Stop the Bleed course. Go to bleedingcontrol.org right now, enter your zip code, and find a free class near you. It's two hours. It covers tourniquet application and wound packing on realistic simulators. I've sent my wife, my teenagers, and my ranch hands through this course. It costs nothing.
5. Assemble or purchase a full IFAK and mount it somewhere accessible. In your vehicle, on your range bag, on your plate carrier if you run one. A kit buried in the bottom of a backpack is not accessible under stress. Mount it, label it, make sure every person on your property knows where it is and what's in it.
6. Stage a permanent marker — a Sharpie — inside every medical kit you own. Tape it to the inside of the pouch if you have to. Write TK and the time on every tourniquet application. This costs forty-nine cents and takes thirty seconds.
7. Run a timed drill this month. Set up a scenario — simulated casualty, dye on a mannequin or a training pad, yelling, chaos — and time your team's response from recognition to hemorrhage control. Record the time. Run it again. Your goal is tourniquet on a recognized extremity bleed within sixty seconds of reaching the casualty. If you can't hit that number, you know exactly what to work on.

I've been doing this for twenty-two years and I will tell you plainly: the gap between people who survive catastrophic situations and people who don't is almost never equipment. It is almost always the willingness to act without hesitation, the preparation to act without confusion, and the discipline to have trained when there was no emergency so that they could perform when there was. Put in the work now, in the comfort of your own property, with the luxury of time — because the moment you need this skill, none of those luxuries will exist. The person bleeding out in front of you, whether it's a stranger on a trail or someone you love, will have exactly one person standing between them and death. Make sure that person is ready.
