Treating a Gunshot Wound in the Field: Tourniquet Application and Wound Packing

Why Most People Get This Wrong

The moment gunfire stops, the clock starts. Uncontrolled hemorrhage from a gunshot wound can kill a person in as little as 3 to 5 minutes. Most people who die from survivable gunshot wounds bleed out before help arrives — not because the wound was unsurvivable, but because nobody nearby knew what to do. That gap between injury and intervention is where lives are lost or saved, and it is filled entirely by whoever is standing closest to the victim.

The hard truth is that most preppers spend significant money on firearms and ammunition but invest almost nothing in the skills and gear required to treat a gunshot wound. Here is what goes wrong when untrained people attempt to intervene:

• Hesitation and panic override action. Without trained muscle memory, people freeze. Seconds become minutes. The victim continues to bleed.
• Improvised tourniquets fail. Belt tourniquets, shoelaces, and cloth strips almost never generate sufficient pressure to stop arterial bleeding. They create a false sense of action while the victim continues to hemorrhage.
• Insufficient pressure during wound packing. Most people pack a wound too gently. Effective wound packing requires firm, deliberate, sustained pressure — more than feels comfortable to apply.
• Wrong placement of the tourniquet. Placing a tourniquet over a joint — the knee or elbow — makes it mechanically ineffective. It needs to sit on a single long bone, 2 to 3 inches above the wound.
• Removing the tourniquet to check the wound. Once a tourniquet is applied in a field environment, it stays on. Removing it restarts the bleed and can accelerate hemorrhagic shock.
• Ignoring junctional wounds. Wounds to the groin, armpit, or neck cannot be treated with a tourniquet. This is where wound packing and pressure become the only option, and most people have no training for it.

Training eliminates hesitation. Gear eliminates improvisation. Both together give a victim a real chance at survival.

The Fundamentals: Step-by-Step Gunshot Wound Treatment

Field treatment of a gunshot wound follows a clear priority sequence drawn from military and tactical emergency medicine: stop the bleed, maintain airway, treat for shock. For our purposes, we are focused on hemorrhage control — the most immediate life threat from a gunshot wound.

Tourniquet Application — Extremity Wounds

Use a tourniquet for any gunshot wound to the arms or legs with significant, uncontrolled bleeding.

1. Expose the wound. Cut clothing away if necessary. You cannot treat what you cannot see. Carry trauma shears for this purpose.
2. Position the tourniquet. Place the tourniquet on bare skin, 2 to 3 inches proximal (above) the wound, on a single long bone — the upper arm or upper thigh. Never place over a joint.
3. Route and secure the band. Thread the self-adhesive band through the buckle and pull it snug — tight enough that it does not slide, but you have not yet applied tightening force.
4. Tighten the windlass. Twist the windlass rod — the rigid handle on a CAT or SOFTT-W tourniquet — until bleeding stops and the distal pulse is eliminated. This will be painful for a conscious victim. It is supposed to be. That pain means it is working.
5. Lock the windlass. Secure the windlass rod in the locking clip or retention strap so it cannot unwind.
6. Note the time. Write the time of application directly on the tourniquet or on the victim's skin with a marker. Medical personnel need this information. The target window before tissue damage becomes a serious concern is approximately 2 hours.
7. Monitor the victim. If bleeding continues through the tourniquet, apply a second tourniquet immediately proximal to the first. Do not adjust or remove the original.

Wound Packing — Junctional and Non-Extremity Wounds

For wounds to the groin, armpit, shoulder, or neck — where a tourniquet cannot be applied — wound packing combined with direct pressure is your only tool.

1. Identify the wound. Locate the entry point. Check for an exit wound. Both need to be packed if present.
2. Pack with hemostatic gauze. Use a Z-folded hemostatic gauze such as Combat Gauze, Celox Gauze, or ChitoGauze. Begin packing at the deepest point of the wound cavity — not the surface. Use your index and middle fingers to push the gauze as deep as it will go.
3. Pack tightly and completely. Continue feeding and packing gauze into the wound until the cavity is full. This is not gentle work. The gauze needs to make direct contact with the bleeding vessel.
4. Apply sustained direct pressure. Using both hands, apply firm, continuous pressure directly over the packed wound for a minimum of 3 minutes — and up to 5 minutes for hemostatic gauze to achieve full effect. Do not let up. Do not check. Hold the pressure for the full duration.
5. Secure the dressing. Apply a pressure bandage — such as an Israeli Battle Dressing or OLAES Modular Bandage — over the packed wound to maintain pressure during movement.
6. Treat for shock. Lay the victim flat, elevate the legs if there are no spinal or lower extremity injuries, keep them warm, and get them to definitive medical care as fast as possible.

What You Need: Gear and Skills Checklist

There is no substitute for purpose-built tools. Improvised hemorrhage control consistently underperforms. Every person in your group should carry a minimum individual first aid kit (IFAK) configured for gunshot wound management.

Minimum IFAK Contents:

• 1x CAT Tourniquet (Combat Application Tourniquet, Gen 7) or SOFTT-W — genuine versions only. Counterfeit tourniquets fail under real pressure. Buy from a verified distributor. Cost: $30–$35.
• 1x Hemostatic Gauze — Combat Gauze (QuikClot), Celox Gauze, or ChitoGauze. Minimum one Z-folded 3-inch x 4-yard package per kit.
• 1x Pressure Bandage — Israeli Battle Dressing (6-inch) or OLAES Modular Bandage.
• 1x Chest Seal — Hyfin Vent Compact or HiCon Chest Seal, vented style, for penetrating chest trauma. Carry two — one for entry, one for exit.
• 1x Pair of Nitrile Gloves — minimum size large, black preferred for low-light visibility.
• 1x Pair of Trauma Shears — 7.25-inch, heavy-duty. Essential for exposing wounds quickly.
• 1x Permanent Marker — Sharpie or equivalent, for marking tourniquet time.
• 1x Emergency Mylar Blanket — for shock management and heat retention.

Skills You Must Have Before You Need Them:

• TCCC (Tactical Combat Casualty Care) course or Stop the Bleed certification — both are available nationwide and many are low cost or free.
• Hands-on tourniquet practice until one-handed application takes under 30 seconds.
• Wound packing practice on training simulators — ask your local EMS or tactical training provider about moulage trainers.
• Shock recognition and management — know the signs: pale clammy skin, rapid weak pulse, confusion, rapid breathing.

Advanced Tactics: What Separates Prepared from Unprepared

Basic IFAK carry and awareness is the floor, not the ceiling. Serious preparedness means layering capability beyond the individual kit.

• Stage a dedicated blowout kit at your vehicle and home. Your vehicle trauma kit should contain at minimum: 2x CAT tourniquets, 4x hemostatic gauze rolls, 2x pressure bandages, 2x chest seals, a nasopharyngeal airway (NPA) with lubricant, and a SAM splint. This kit lives in a dedicated pouch — not mixed in with general gear.
• Practice under stress and low light. Your hands need to perform these skills in the dark, in the rain, with adrenaline flooding your system. Train accordingly. Dry-fire training has a direct analogue here: slow is smooth, smooth is fast.
• Learn needle chest decompression. Tension pneumothorax — a collapsed lung caused by a chest wound — can kill faster than blood loss. A 14-gauge needle, 3.25 inches long, inserted at the second intercostal space, midclavicular line, can decompress it. This is an advanced skill requiring proper instruction but it belongs in your long-term training progression.
• Designate a medical lead in your group. Someone in your household or survival group should pursue EMT-Basic or Wilderness First Responder (WFR) training. This person becomes your field medic. Spread the knowledge — never let your medical capability live inside one person.
• Know your evacuation routes. Field treatment buys time. It does not replace a surgeon. Know the location of the nearest Level 1 Trauma Center from your home, your bug-out location, and your regular travel routes. Time to definitive care is the determining variable.
• Maintain your gear. Check tourniquet velcro for lint and debris monthly. Replace hemostatic gauze 12 months before its printed expiration date. Heat degrades medical supplies — do not store IFAKs in vehicles during summer months in hot climates unless the kit is rated for temperature extremes.

The Bottom Line: Action Steps to Take This Week

Reading about hemorrhage control does not save lives. Doing the following will:

1. Order a genuine CAT tourniquet and Combat Gauze this week. North American Rescue, Rescue Essentials, and MyMedic are reputable U.S. suppliers. Budget $60–$80 for a starter IFAK build.
2. Register for a Stop the Bleed course. Visit stopthebleed.org. Many courses are free, run 2 hours, and cover tourniquet application and wound packing with hands-on practice. No prior medical experience required.
3. Build an IFAK for every person in your household. Carry capacity is irrelevant if the person next to you is bleeding and has no kit. Equip your people.
4. Practice tourniquet application until it is automatic. Set a timer. Apply your tourniquet one-handed to your own upper thigh. Repeat until you can do it correctly in under 30 seconds without looking at the device.
5. Locate your nearest Level 1 Trauma Center. Map the route. Know the drive time. Save the address in your phone and in your paper emergency contact card.
6. Schedule a quarterly gear audit. Put it on the calendar. Check expiration dates, inspect velcro, verify windlass function, replace anything compromised.
