U.S. Army uses online teaching app to create digital flashcards to remember classified content, risking leaks

British investigative website Bellingcat revealed on Friday that U.S. military personnel responsible for guarding nuclear weapons in Europe have been using several online educational applications to create digital flash cards to memorize long and complex security protocols, or have compromised their locations and security protocols.

In order to remember where to store live nuclear weapons and security patrol schedules, U.S. military personnel create flash cards using online applications such as Chegg Prep. Foeke Postma, the author of the report, said a simple online search for nuclear weapons-related terms revealed flashcards used by military personnel stationed at six European military bases.

Bellingcat said NATO and U.S. forces were notified before the article was published, and the flashcards appear to have been removed.
