Question: When Witt is in the clearing surrounded by Japanese riflemen, does anybody know what the Japanese soldier was saying to Witt before he shot him?
Answer: These were barrage balloons, commonly used during the war. They are used to stop low level bombing and low level fly bys by enemy fighter planes. The cables attached to the balloons are designed to cut through the wings of the aircraft and to bring them down, so any pilot would have to fly above them, and the balloons would also restrict the view from above.
