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 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.
