Gas Gas Gas

The M17 mask was issue in Vietnam.

Outside of a few photos in Hue, try finding anyone carrying or wearing one.  Even then, you're just as likely to be looking at the older M9.

I remember that one of the reasons they stressed we shave and keep our mustaches severely trimmed was to be able to seal a gas mask against our face.

Funny New Guys raises a question.  Except for the spider and snake people, there's fur and feathers on their faces.  Never mind the shape of the skull and face differs from baseline H. Sapiens.

Considering how recent the decision to allow chimera into the Army was, it's doubtful new equipment to accommodate them has even started development.

But, back to the original point.

Soldiers ditch the masks as soon as they think they won't need them.  Bill Mauldin even made a comic about it!

"I see that E comp'ny got th' new style gas masks"

And so it goes...
