Shelter-in-Place During Combat

Know how to fortify your shelter, protect your family, and survive inside a building when active combat is occurring in your immediate area.

When fighting reaches your immediate area and evacuation is impossible — roads are blocked, snipers are active, or the fighting is too intense to move through — sheltering in place becomes your only viable option. Done correctly, staying put in a well-chosen and prepared location can be safer than attempting to move through an active combat zone.

Shelter-in-place during combat is not passive. It requires deliberate preparation, continuous situational awareness, and disciplined behaviour. The goal is to make your location as inconspicuous, defensively sound, and self-sufficient as possible until either the fighting passes or a safe window for movement opens.

Choosing Your Safe Room

Not all parts of a building are equally safe. The right room choice significantly affects survival odds.

Ideal Safe Room Characteristics

FeatureWhy It Matters
Interior room (no exterior walls)Exterior walls are vulnerable to direct fire and blast; interior walls provide an additional barrier
Below ground level (basement)Best protection from indirect fire (artillery, mortars, airstrikes)
Ground floor or below (if no basement)Lower floors survive collapse better; upper floors are more exposed
No windows, or windows you can sealWindows are fragile and allow shrapnel, glass, and blast to enter
Multiple exitsEssential for escape if one route is blocked
Near a load-bearing wallProvides structural integrity during blast
Not near a strategic targetNot the room adjacent to a generator, communications antenna, or weapons storage

Reinforcing Your Position

  1. Sand-bag or fill walls with dense material — bookshelves filled with books, stacked furniture, sandbags, or soil-filled containers all absorb projectiles. 30 cm (12 inches) of packed soil stops most small-arms fire.
  2. Seal windows — nail plywood over windows; seal gaps with tape, wet towels, or clothing. This protects against glass fragmentation and some blast pressure.
  3. Create a low crawl space — under a sturdy table, behind a solid bookshelf, or in a bathtub. These positions protect from ceiling/floor collapse and blast concussion.
  4. Mark your location — display a white flag, white cloth, or white cross from a window or roof to signal to forces that civilians are present. Do this carefully and only when it is safe to approach the window.

Supplies to Stockpile in Your Safe Room

Prepare before fighting reaches your area:

ItemQuantity / Notes
Water4 litres (1 gallon) per person per day — minimum 2-week supply if possible
FoodNon-perishable, no-cook items — 2-week supply
First aid kitTrauma-capable: tourniquets, pressure bandages, Israeli bandages
MedicationsFull supply of any prescription medications
Torch + batteriesMultiple — red-light mode for night use to reduce visibility
Hand-crank or battery radioFor monitoring official broadcasts
Portable phone chargerFully charged; ration use
BucketsFor sanitation if water supply is disrupted
Plastic sheeting + tapeFor sealing windows/gaps against chemical or fire threats
Fire extinguisherArtillery and airstrikes frequently ignite fires
WhistleFor signalling under rubble if building collapses

Behaviour During Active Combat

The 3 Rules of Combat Survival in Place

1. Stay down. Most non-combatant casualties in urban combat are caused by people who briefly stood up, looked out a window, or walked upright in a location with line-of-sight exposure. Move by crawling. Stay below window level at all times.

2. Stay silent. Noise attracts attention. Keep children calm. Turn off phone ringers. Do not use power tools or machinery. Communication should be whispered.

3. Stay put. The impulse to run during a pause in fighting is strong. Resist it unless you have confirmed intelligence that a safe route is open. Most people killed while trying to flee are killed during a brief lull that ended before they reached safety.

Sounds and What They Mean

SoundMeaningAction
Distant gunfireFighting in area — not immediateStay low, monitor
Nearby gunfire (within 1–2 blocks)High danger — active combat closeGet to safe room, stay flat
Artillery/mortar (incoming whistle, then explosion)Indirect fire in areaBasement or lowest interior position immediately
Jet or helicopterPotential airstrikeAway from windows, basement, under solid cover
Silence after sustained fightingPause — could resume at any timeDo not move yet — wait at least 30–60 minutes
Troops entering buildingActive combat in your buildingStay absolutely still and silent; do not approach doorways

⚠️ If armed combatants enter your building: Lie flat, remain completely still, and make absolutely no sound or movement. Announce your presence only if directly confronted — do so with hands visible and no sudden movements. Do not attempt to flee through rooms where combatants are present.

Fire Risks During Combat

Artillery, airstrikes, and Molotov cocktails create fires. Fire is one of the leading causes of civilian death in urban combat.

  1. Keep fire extinguishers accessible in your safe room.
  2. Have an escape route planned for fire — if the building catches fire and cannot be controlled, you must leave even during fighting.
  3. Feel doors before opening — a hot door means fire on the other side; do not open.
  4. If fire is in the building: crawl low (cleaner air near the floor), cover your nose and mouth with a damp cloth, and exit via the safest route. Moving through light gunfire may be less deadly than burning to death.
  5. Seal gaps under your safe room door — wet towels slow smoke infiltration.

Medical Preparedness

Hospitals and emergency services are non-functional during active urban combat. You must be prepared to treat injuries yourself.

Essential Skills to Know

  • Tourniquet application — can stop life-threatening limb bleeding in 30 seconds when applied correctly
  • Pressure dressing application — for wounds where a tourniquet cannot be used (torso, neck, groin)
  • Wound packing — for deep wounds, packing the wound cavity with gauze and applying sustained pressure
  • Keeping airways clear — unconscious person: recovery position; ensure no obstruction
  • Treating shock — keep victim lying flat, elevate legs if no spinal injury, keep warm

Sanitation Without Running Water

Extended shelter-in-place means managing waste without functioning toilets:

  1. Line a bucket with a plastic bag. Add a small amount of dirt, ash, or cat litter after each use to reduce odour and pathogen risk.
  2. Keep waste containers outside the immediate living space if possible.
  3. Maintain strict hand hygiene — use water sparingly but always wash hands after sanitation.
  4. Dispose of waste away from water sources.

When to Break Cover and Move

The decision to move from shelter requires:

  1. Confirmed intelligence — from radio, phone contact, or direct observation that a specific route is safe.
  2. A clear destination — not just "away from here" but a specific, safer location.
  3. The right window — typically early morning, during sustained quiet periods, or following an announced ceasefire.
  4. Minimal profile — plain clothing, no backpacks (too military-looking), white cloth visible, hands visible when approaching any checkpoint.
