A healthy person lying in the snow at -30 or -40 dies of hypothermia. Add a gunshot wound, wet clothes, and twenty minutes on the X while the team finishes the fight, and the cold competes with the bleeding.
Thomas spent nine years as a Danish Special Forces operator and medic. His view is that TCCC still applies, but the sequence does not survive contact with that climate unchanged.
Stripping a chest or abdomen to “do MARCH” on the snow makes the patient colder, more coagulopathic, and more acidotic. Massive hemorrhage still gets a tourniquet, over the clothing, because it is fast. Airway obstruction gets a roll to prone. Everything else waits for a semi-controlled heated shelter. That shelter is not a rock. It is a tent, a stove, and enough security to put both up.
Clothing changes the tools. A CAT may not reach a thigh under five layers. Mittens make the windlass clumsy, and taking them off at these temperatures is a frostbite problem in minutes. Train with the gloves you will wear. Inside the tent, two multi-fuel burners on a stable platform, a vapor barrier, and active heat come before a full secondary survey. Drugs he keeps close: ketamine, morphine, prefilled syringes rather than ampules, and an IV antibiotic. Plastic IV bags leak and contaminate when they thaw. Crystalloid and albumin in glass survive better. Blood products are still plastic. Freeze-dried plasma can work, but it needs fluid and time.
Hypothermia is a whole-team threat, and it outruns a lot of procedures. At these temperatures a down patient, especially a bleeding one, does not have a normal MARCH window on open snow.
Tourniquet over the clothing. Then get to heat. Do not strip chest or abdomen on the X. Airway obstruction gets prone positioning. Tactical field care starts in a heated, semi-controlled shelter, not behind a rock.
Gloves stay on. Test the tourniquet on the real clothing. Layer bulk can force a second tourniquet. Bare hands at minus forty are a frostbite injury in minutes. Practice the application you will actually do.
Cold kills the kit. Batteries die. Plastic IV bags leak when they thaw. Prefer glass vials and glass crystalloid. Freeze-dried plasma is possible if you have fluid and minutes. Prefilled syringes beat ampules with numb fingers.
The first shelter is a planning problem, not a terrain feature. You need time and security to pitch a tent and light a stove. Ten minutes down at minus twenty-five was enough to drop consciousness in a non-trauma patient. Wool, a stove you can start in mittens, and a tent you can pitch fast are medical equipment.
