True, but in this case, civilian requirements may be "protects against ambient fumes" while the military specs are "protects against deadly gases that are designed to try to get around gas masks while standing up to impacts and sweat and still allowing enough freedom of movement to engage in combat". Like yeah a mil-spec spoon isn't going to be substantially different than a civilian spoon, but there are some things that even barely meeting the military standard at the lowest possible price is still better than what you get going for civilian specs
