LOL, ain’t that the truth. The military can’t even provide all vets with their DD-214 because of a fire a long time ago.
[Unless you’re Bill Clinton or John Kerry, in which case a mysterious fire breaks out in the warehouse.]
They did have a fire that got a bunch of records but the military was able to reconstruct them by tracking down duplicates from every command an individual had spent time at. This had to be labor intensive but at the time a lot of veterans were accusing the VA of burning the warehouse so they could cheat people out of their benefits.
And you’re right—a lot of “Vietnam” thespians used that fire to explain why their exploits, or even a record of their enlistment, couldn’t be documented.
