I wonder if military-style but non-aggressive organizations exist? They would make sense... wait a bit, I have an idea. Are there backoffice, analytical jobs in the fire service? Not a frontline fireman/firewoman, but something sort of a strategist. Making plans for national disasters, stuff like that, but still a bit uniform-wearing stuff with ranks and whatnot.
Those jobs exist in the police force and I would be very surprised if most countries didn't have something like what you describe.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
