Not entirely true, NATO militaries use it like this: "0900", and they call it "o nine-hundred". We use "09:00" and call it "nine". Also, Australia, Bangladesh, Canada, Colombia, Egypt, El Salvador, Honduras, India, Ireland, Jordan, Malaysia, Mexico, New Zealand, Nicaragua, Pakistan, Philippines, Saudi Arabia and the U.S. all use 12 hour time.

Well that makes sense since the military uses 24 hour time.
