Intelligence documents include reports of information gained from prisoner-of-war interrogations, radio intercepts and information reported by friendly patrols, along with intelligence passed from higher headquarters, such as weather predications and enemy order of battle information; G-2/S-2 Journals provide constantly-updated accounts of information reported to the recording headquarters in much the same format as the G-3/S-3 Journals.
