NonCredibleDefense

Yeah, that's what I thought. It's been 8+ years since I had to do anything ITAR so I couldn't remember if it also applied to information. From what I remember it explicitly controls products that are purpose built or components of defense systems (and by that I mean 'Arms').

While I'm sure Warthunder thought the best idea was to say "fuck that, we aren't touching this live wire with a 20 foot long insulated fiber glass pole" and the manual itself is export controlled (as it aids in use of the F-117 system) there isn't a new national security threat because of it being shared publicly. Part of the reason ITAR exists, if you make it difficult or impossible to obtain all the parts of a system, that system is going to have a hard time working correctly.
