Remarkable interactive Iwo map. You add the MGs, and are impressed, then just keep layering on the stuff they had to assault. Very well done. (Doesn't work so well on mobile for formatting reasons.) Battle of Iwo Jima
Fascinating and brilliantly done. Also appalling. Practically every inch of the damned place was covered by fire. I have seen weapons maps of Tarawa and I thought that was bad, but this is even worse. If I had been the force commander and had been asked if I could take the island I would have said "yes, but only if you bombard it for about a year. Or let me use poison gas." It does make you appreciate the men who did take it, that's for sure.
The Iwo Jima map was made by the guys at Project'44. They do top-notch and well-researched work and it is well worth checking out their other interactive maps as the Iwo Jima map is just the tip of the proverbial iceberg. One of their next projects is Hong Kong '41 which I am eagerly anticipating!
