Speaking as a USAF Veteran, they are very strict about honesty, and there's actually a whole set of meta-laws (the UCMJ, https://www.military.com/join-armed-forces/the-uniform-code-...) which are stricter than civilian laws, that all members of the US military must adhere to. (Let's just say I got one personal taste of this during a "white lie" incident I was a part of.)
The pilots who reported "foo fighters" https://www.smithsonianmag.com/air-space-magazine/what-were-... in WW2 were under the same rules.
I would therefore consider any reports by active military to be head and shoulders above others, at least on the assumption of dishonesty. (That still leaves the possibility of misperception, mis-recall, etc.... but if you consider each person an imperfect detector of information, then the more people reporting a thing, the more accurate the picture becomes thanks to sensor fusion/the Kalman filter: https://medium.com/@cotra.marko/wtf-is-sensor-fusion-part-1-... )
