The M40 Field Protective Mask is one of various gas masks used by the military of the United States and its allies to protect from field concentrations of chemical and biological agents, along with radiological fallout particles. It is not effective in an oxygen deficient environment or against ammonia. The M40 Field Protective mask features two voicemitters, one on either the right or left side, and one in front. A voicecom adapter may be placed over the front voicemitter to amplify the user's voice.
