The tactical doctrine of a "Kill Box" first came into useage in the intensive bombing campaign conducted against the Japanese 3rd ID, 1st Tank Division, and the 4th ID of the Royal Thai Army. As you know, the divisions had been herded into the open by operation SkyFall in which the Chindits seized Undon Thani from the Thai army blocking the escape route for these three units. Caught in the open, they were subjected to a ruthless bombardment from the air with approximately 500 planes dropping more than 600 tons of high explosive per day on them. To manage the large number of daily sorties the Army, Indian, and Royal Air forces worked out a system that divided the target area into a series of boxes each of which was the exclusive responsibility of a specific squadron. A command aircraft circled the battlefield directing incoming strikes. By the end, these three units had been subjected to almost as much firepower as had been dropped on Hiroshima.
