The number of state secrets protected by a 20 year old E-4 whose only motivation is to not get chewed out (and/or jail) is probably staggering.

A lot of these tank "leaks" are just PDF's of manuals you can buy on ebay. They're restricted but legal to own. It only becomes illegal when you export them to other countries.

I believe what GP is referring to is the Air Force National Guardsman who's going to jail for leaking classified intelligence on a discord server to prove he was right. I don't think it was actually about tanks, just that it happened in a WarFrame discord (or something like that).

Being prosecuted and imprisoned by the federal government is far more motivation than being terminated from a low paying job.
