The unique thing about Iwo Jima is that it was a panoramic battlefield, a spectacular epic, like a movie. With a good pair of binoculars sailors aboard ship could watch the battle unfold.
I find that fascinating. I can't think of any other battlefield of WWII that was so visible in its entirety.
That aerial shot of Suribachi and the waves of amtracs heading toward the beach, the explosions, dust and smoke...surreal.
