On several occasions, users on the War Thunder forum have shared restricted and/or classified documents during discussions about the accuracy of the vehicles depicted. In all cases, offending posts are removed by the moderators, and users are warned against sharing such documents. Anton Yudintsev, founder of Gaijin Entertainment, has stated that the development team is never exposed to the contents, reminding users that "it's both illegal and pointless, so they should never do that". In January 2023, Raytheon denied media reports that security clearance background checks for jobs at the defense contractor investigate whether applicants play War Thunder.
