Tactics to evade Japanese antiaircraft fire when strafing airfields during WWII from Informational Intelligence Summary, Office of the Assistant Chief of Air Staff, Intelligence, Washington, D.C., 1944.
P-38s EVADE JAPANESE AA BY CONTINUOUS TURN
One tactical secret of the outstanding success of a P-38 Squadron engaged in recent airdrome strafing missions in Burma consisted of maintaining a continuous turn from the time of arrival in the target area until the last instant before making the firing pass across the airdrome.
(AC /AS, Intelligence Flak Note: This technique doubtless was employed when terrain features and identification problems made absolute surprise, which is the cardinal rule of ground strafing, difficult to attain. This practice prevented Japanese heavy antiaircraft gunners from putting up an accurate barrage ahead of the attacking aircraft and threw off the calculations of their fire control directors. The computing sights of Japanese automatic weapons, which make up the larger portion of airdrome antiaircraft defenses in Burma, were also rendered comparatively ineffective by this stratagem.)
