Military combat clothing and equipment have evolved significantly over time to address changing threats and technologies. Advances in long-range weapons at the turn of the 20th century required camouflage to hide troops from a distance. During World War II, new fibers like nylon and fabrics like Ventile improved functionality. The layered clothing concept introduced in 1943 enhanced protection and comfort. Modern military textiles aim to balance protection from threats with lightweight breathability and camouflage, addressing issues like ballistics, weather, and nuclear/biological/chemical hazards.
