Yeah, there's always contention over EPO buttons, too! Surprise-surprise that operators don't like a giant red "push here to kill the mission" button right out in the open where anyone can push it. There's enough weasel words in 645.4 that they frequently get their way, too. Some might consider the lack of fire-rated walls a violation... others, the excuse they need to ignore other codes they don't like.
DoD instructions, MIL-HDBKs and the like are like NFPA, though, in that they're living documents that can be changed; easier, really, because there's no set time limit, they can be revised at any time, and there's usually only one person that needs convincing and an email from them is just as good as an official revision. It's just a matter of finding the person (or office) who's responsible for it and giving them a call.
