Doctrine audiobooks can be downloaded from the Central Army Registry (CAR) at https://rdl.train.army.mil/catalog/#/search?search_terms=audiobook.  Audiobooks are produced from authenticated doctrine, but are abridged for the audiobook format and considered a doctrine supplement.  Since fiscal year 2019, CADD has developed more than 90 doctrine audiobooks for the Army. The audiobook format is considered for manuals with sufficient shelf-life, broad appeal to the force, and interest shown by number of publication downloads.

**Under Construction** The Combined Arms Doctrine Directorate hosts more than 150 videos on the Combined Arms Command Fort Leavenworth YouTube channel. These videos supplement Army doctrine. In short form, Doctrine Digest delivers information about a single doctrinal term or concept. Special projects, such as our FM 3-0 documentary, provide viewers with more detailed explanations of Army doctrine-related topics. ​They also deliver a substitute for mobile training teams when funding or schedules do not permit an in-person training experience.
