My dad was a field radio guy in the Marines at Iwo Jima. Our of 21,000 Imperial Japanese troops on the island, fewer than 1,000 were captured. I've got a recording of an interview he did after the battle with Chicago radio station WLS on the troop ship headed back to Hawaii -- where he was to train for an invasion of the main islands that A-bombs made unnecessary -- and he described having to shoot and bayonet Japanese soldiers doing Banzai attacks at night. He was 19. I visited Iwo Jima with a couple hundred veterans of the battle on the 60th anniversary in March 2005. (Dad died in 2002.) Met a lot of fine former Marines and sailors and Navy corpsmen and Seabees. Just about all gone now. Gunny Sgt. R. Lee Ermey came along to do an episode of his show about them.
