Wet, Cold, and 18 Kilometers In

Assessment: moderate hypothermia, heading toward severe if nothing changes.

Key indicators and why they matter:

• Violent shivering means the body is still trying to generate heat. That is a good sign, and it stops being present as hypothermia worsens.
• Fumbling with gear shows fine motor coordination is gone - a reliable early field sign that core temperature is falling.
• Confusion (answering with the wrong name) is the red flag. Mental-status change moves this from mild to moderate, and it is the finding most often missed because the soldier is still walking and joking.

Priorities in the first hour:

1. Stop the heat loss before adding heat. Get out of the wind and rain, put the poncho over and under the casualty as a windbreak and ground sheet, and get him off the wet ground.
2. Remove wet clothing and replace it with dry insulation. A hypothermia wrap - dry layers, space blankets, and a warm person in the same bag - is far more effective than a blanket over wet clothes. Protect the trunk, head, and neck first.
3. Handle him gently. Rough movement of a cold patient can precipitate cardiac arrhythmia. No forcing him to walk fast, no rubbing limbs, no hot water bottles against bare skin.
4. Warm, sweet fluids by mouth only if he is fully alert and can swallow. No alcohol, no caffeine.
5. Keep him with a buddy at all times and recheck mental status every 15 minutes. Document the trend.

Do not: put him in a sleeping bag alone, send him walking to warm up, or delay evacuation because he is still conscious. Confusion plus a 4-degree rain is a deteriorating picture, not a stable one.

This is a genuine tradeoff between detection risk and a life-threatening condition, and it should be decided deliberately rather than by habit in either direction.

The case against a fire: a hunter-killer element with night vision is 2 kilometers away, and an open flame is visible at that range even in rain. A fire also produces smoke and smell, and a lit position is a fixed position.

The case for a fire: moderate hypothermia with mental-status change will not be reversed by the poncho and two space blankets alone in steady rain, especially with no dry fuel and no stove. If PFC M deteriorates to severe hypothermia, the risk calculus changes completely.

Middle paths, in order of preference:

1. Shelter and insulation without flame. Find a lee side of a ridge, a dense evergreen, or a downed tree; build a debris bed for insulation from the ground; use the poncho as a roof; use the heat tab for a small amount of warm water if it can be done without a visible flame.
2. A concealed fire if needed. In a deadfold or behind a terrain mask, under a poncho or a natural roof, with dry deadwood from standing dead branches rather than wet ground wood, and kept small. A Dakota fire hole reduces visible flame and light but takes time and good soil.
3. Full fire, accepted risk, only if the soldier's condition is clearly worsening and the team's alternative is a casualty who cannot walk out.

Command judgment: I would set a trigger. If PFC M cannot answer simple questions or stops shivering, the fire gets built and the team accepts detection risk, moves a short distance after warming, and reports the decision to higher. A cold casualty who cannot move compromises the whole team's exfiltration, which is a bigger tactical problem than a small concealed flame.

Water: one liter for four soldiers is the next crisis.

• Rationing to a few sips each buys a few hours at best. The real answer is collection. Rain is falling steadily; the poncho can be rigged as a catch basin with a container underneath, and water can be collected from a clean surface. It should still be treated - purification tablets or a filter if the team has one - because surface collection in a training area carries risk.
• Do not eat snow or ice; it costs more body heat than it provides water.
• Cold, wet soldiers under-drink because they do not feel thirsty, which worsens fatigue and accelerates hypothermia. Set a drinking schedule rather than waiting for thirst.
• Avoid unnecessary sweating. Overexertion in wet clothing soaks the insulation and accelerates heat loss for everyone, not just the casualty.

Extraction decision:

The 0600 request deadline and the 3-kilometer move to the landing zone create a hard decision point. Working backwards: if the team cannot reasonably reach the landing zone by first light with a confused casualty in tow, the request needs to be made now, not later.

I would request the daylight extraction at the landing zone and simultaneously plan the foot exfiltration as the primary course of action, with the landing zone as a contingency. Requesting support does not commit you to using it; failing to request it forecloses the option.

What goes into the request: location, number of casualties and precedence, the nature of the injury (hypothermia, mental-status change), the marking method for the landing zone, and the security situation. Then the team moves toward the landing zone at a pace the casualty can sustain, with the casualty in the middle of the formation, and reports any deterioration. The judgment is not "call or don't call" - it is keeping both options alive until the terrain or the casualty's condition makes the decision for you.
