Why you should never run through smoke you didn’t throw

When Army basic training soldier Jennifer Campbell was told to run through smoke on the obstacle course, she leaned into it and went for the awesome photo moment of charging through the thickest plume of smoke.

Unfortunately for her, it wasn't white smoke; it was o-chlorobenzylidene malononitrile, a potent form of tear gas used to teach basic trainees to trust their chemical masks and other gear. But Campbell wasn't wearing chemical gear; she was running full speed and sucking down air on an obstacle course.

So the young soldier got two lungs full of the agitating gas, forcing violent coughs as her drill sergeants got a good laugh and the other trainees scrambled to get their masks on.

But what doesn't kill you makes you stronger, and Campbell got her own laughs when the winds shifted and the rest of her platoon got hit unprotected, including the drill sergeant who triggered her episode. See how it all went down in the Go90 video embedded at the top.
