You'll need to satisfy the airline and also meet the requirements for Japan. My impression is that military and their families are treated somewhat like embassy staff and their families and are often exempt from quarantine, etc. requirements providing that they travel directly to the base.

However, doesn't the Fly America act, or whatever it's called, require travel on USA carriers when the government is paying unless there's no alternative, however unreasonable in terms of schedule, routings, connection times, etc. unless you have a mission-related exemption.
