Old, clear outserts tended to yellow with time and was considered a deadlining condition for the mask since accurate color vision was required to assess sometimes subtle color changes on the M256A1 chemical detection kit required for unmasking procedures. Three varieties of outserts were available for the mask clear for general operations, gray tinted for bright environments, and green tinted to protect the wearer from battlefield lasers. These protective masks have inbuilt voice emitter systems that facilitate communication, a tube for drinking water from the M1 canteen cap (A1 & A2), and a pair of outserts to protect eye lenses and an air pathway that reduced fogging. Notable copies include the Bulgarian PDE-1, Japanese Type-3, the Polish Mp-4 and the Czech OM10 or M10M. Many countries have copied the M17 design.
