American soldiers wearing M2 gas masks in a frontline trench (1919 postcard image)
The M2 gas mask was a French-made gas mask used by French, British and American forces from April 1916 to August 1918 during World War I.[1] The M2 was fabricated in large quantities, with about 29,300,000 being made during the war.[2] It was intended to protect the wearer from at least five hours' exposure to phosgene gas, a common chemical weapon of the time.[3]
