In addition, it prepares such special information and intelligence studies as required by The Joint Board, or as may be indicated by the situation. While it maintains a file of reports, correspondence, etc., no intelligence files as such are kept, but the members are given full access to the reports and files of the Military Intelligence Division, and the Navy Intelligence Division. Joint Summaries of Information are principally factual. Doubtful information is so indicated. Joint Strategical Estimates of the Situation are reserved as a function of the Joint Planning Committee.
