Characteristics
The M40 Field Protective mask features 3 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. The mask can be adjusted in the field to accept the filtering canister on either side, so that a weapon may be shouldered. Right-handed shooters will normally locate the canister on the left side of the mask and vice-versa.
The C2 canister on the M40 mask can protect the user from up to 15 nerve, choking, and blister agent attacks, and two blood agent attacks.
The M40 comes with a drinking system that allows the user to drink water when donning the mask for long periods of time in a chemically contaminated environment. In order to use the drinking system the user must also have suitably equipped canteen lids or an adapter for other containers.
