MCU-2/P Protective Mask



The MCU-2/P is a gas mask used by the United States Navy and United States Air Force, adopted in the 1990s. It replaced the earlier M17 gas mask & M17A2, and is itself scheduled to be replaced by the M50 Joint Service General Purpose Mask. The MCU-2/P features a single large lens and a side-mounted filter. A clear or tinted visor and protective hood are used in conjunction with the mask.

Like the Army and USMC M40 mask, the MCU-2/P's silicon rubber facepiece was found to be susceptible to corrosion from blister agents, rendering it of little value on the battlefield. A second skin can be worn over this to prevent corrosion.
