Horse gas masks were first used during World War I to protect horses from harmful chemical agents. Horses were the primary mode of transporting men and material to war zones and needed protection from irritating chemicals like chlorine and phosgene, used during that time. The mask on the right is a post war Soviet mask accompanied by a pair of gas proof goggles. Like most horse respirators, this mask was probably used in conjunction with a gas proof cape and leggings.
