Okay the pedo-stache is a thing. Usually seen on oddballs and Majors. Of course he's out of regs too. The mustache can't go past the corners of the mouth.
The reason, if anyone cares, is so that your mask gets a good seal to your face to protect you from gas attacks, etc....
Fun fact, that is why Hitler shaved his mustache the way he did. Before he rose to power, he was in a gas attack, and it's theorized that his mustache broke the seal, and the gas he inhaled made him insane.
