One of the more crazy experiences anyone in the U.S. Marine Corps will have and remember for a lifetime is the first time you go into the gas chamber. As a new recruit, you have no idea what to expect. One thing is for certain though, when you leave the gas chamber after the initial coughing and spitting, you’ll suddenly be able to breathe better than you ever have in your life.
These Marines are going through their training with the use of the mask and seals so it looks like this isn’t their first go around in the chamber.
It’s no easier going through the second time, but at least you know exactly what to expect. The gas chamber is good training to go through because you never know what you’ll encounter while in combat.
