Core Gear for Extreme Cold Warfare: The Ural felt boots (Valenki) used by the Soviet Army on the WWII Eastern Front were crafted from thick wool felt for air-locking warmth. Stuffed with hay or newspapers, they prevented frostbite even at -30°C and became prized survival supplies seized by German troops.
Individual Gear & Field Camping: Felt is made into hats, coats and mats to block ground cold; laying felt in temporary bunkers enhances moisture-proofing and heat retention, boosting field survivability.
Ancient Military Legacy: Both the Yan State (Warring States Period) and the Yuan Dynasty Mongol army relied on felt as standard cold-protection gear to preserve combat effectiveness in frigid conditions.
Temporary Paths & Obstacle Breaching: British Churchill AVRE tanks in WWII carried brushwood-felt mats to quickly lay passable routes on soft terrain, or enable soldiers/vehicles to cross barbed wire—ideal for amphibious landings and breakthrough operations.
Improvised Fortifications: In the Qing Dynasty’s "Camel City" tactic, wet felt mixed with sand was laid on camels’ backs to block musket fire and extinguish rockets, forming mobile defensive strongholds.
Noise Reduction & Stealth: Felt absorbs sound and dampens vibrations; lining bunkers and command posts with it reduces noise and oscillation, lowering the risk of detection.
Sealing & Shock Absorption: Felt gaskets and shock-absorbing liners are used in engine compartments and transmission systems of tanks and armored vehicles to prevent dust ingress and reduce mechanical noise.
Filtration & Protection: Military-grade filter felt is deployed for vehicle air intake and fluid filtration; equipment is wrapped in felt during transport to avoid collision damage and scratches.
Medical Aid & Bandaging: In emergencies, clean felt serves as temporary stretcher padding and wound dressings to isolate contaminants.
Signaling & Marking: Dyed felt is used to make makeshift signal flags and position markers—low-cost and quick to produce.
Nomadic Military Camps: The Mongol army’s yurts, covered in multi-layered felt, are easy to assemble and disassemble, acting as mobile camps for long-distance expeditions.
