Air Force IMPACT
IMPACT is a medium for the dissemination, in graphic form, of air intelligence and correlated subjects. It presents information on the results of our operations against the enemy. So that Air Force units in one theater may be informed of how units in another meet specific problems, pertinent data on the operations themselves is also included. This publication is classified CONFIDENTIAL - DISTRIBUTION: SQUADRONS so that a maximum of available data can be included but it is intended that it be read by every member of our armed forces to whom its information may be of value. Material which members of the Army Air Forces in the field believe suitable for publication should be forwarded with descriptive text and special annotations when necessary through regular channels marked for the attention of IMPACT. IMPACT's format is 8-1/2 X 11 inches. Average number of pages varies widely from 46 - 58
