PMG

The Russian PMG is a gas mask produced in the 80s for Russian civil defence troops and infantry, the mask looks very similar to the SCHMS gas mask but it has a side loading filter and a different voice diaphragm. It uses the standard Russian ГП-5 (GP-5) filter, which was the default for all soviet 80s-90s Gas Masks.

The mask is most famous for appearing in Half-Life 2 being worn by the Combine  police called Civil Protection.
