The M9 Series Field Protective Masks are some of the most successful gas masks to be used by the United States military, derivations being adopted by at least six other countries. Starting production around 1947, the M9 Series remained in standard infantry service until the early 1960s, when it was phased out with the introduction of the M17 Field Protective Mask .

Despite being replaced as a standard infantry mask by the M17 Series during the early/mid-Vietnam War, the M9 series continued service with National Guardsmen and Law Enforcement (even though they had specialty gas masks of their own) during protests against the war. It was also issued to Civilian Defense workers and civilians alike, and the M9 series would be used by these organizations up until the 1970s.

Even after the M9 series was phased out by general infantry, policemen and civilians alike, it continued its use by the U.S. Heavy Decontamination Crews, Chemical Stockpile Inspectors and Handlers, and EOD Personnel used the mask from its conception in the late 1940s until the early 1990s as a part of the ABC-M21 Rocket Propellant, M15 Compressed Air Breathing, Toxicological Agents Protective (T.A.P.) Gear ensembles.
