Some military gas masks are mainly made of activated carbon cloth, or with water- and oil-resistant fabric as the outer layer, glass fiber filter material as the inner layer, and polyurethane foam plastic soaked in activated carbon as the bottom layer, which can provide temporary protection against sudden attacks by poisonous gas. The gas mask is a work of biomimicry, inspired by wild boars on the battlefield after another war. Chemical weapons were used, but after the war it was discovered that wild boars were not harmed, so gas masks and respirators were made in the shape of wild boar noses.
