Novus Ordo

Matt – the ones we were issued were good pretty much indefinitely while in a sealed bag – 30 days once opened in an uncontaminated environment – 24 hours in a contaminated one.  They had some expiration dates on the cannister, but we used to use those for training with CS in the chamber and they still worked fine; they just weren’t good for the real chemical warfare.

Arms discourage and keep the invader and plunderer in awe, and preserve order in the world as well as property... mischief would ensue were the law-abiding deprived of the use of them.
