In case you missed it, the CDC announced last week that we can stop masks and social distancing for people that are fully vaccinated. Of course, use your best judgement as to whether or not that pertains to you in your bi-annual gas chamber training.
It probably doesn’t.
The gas chamber is a ubiquitous Marine Corps experience that we all love to hate. Your first journey into the spicy bunker starts in boot camp, where you learn how to equip your issued mask and clear it, etc., in a room filled with CS (tear) gas. The training becomes bi-annual after that (or rarely if at all, depending on your unit).
If nothing else, the gas chamber is a fun place to watch recruits and Marines alike experience immense regret for their life decisions up to that point. It’s also great to clear out the sinuses.
