I recently read a book called IWO by James Wheeler and it was one of the best reads I can recall. I have always had a high respect for all troops in all of America's wars including the Civil war, but after reading the book and learning about this long and deadly battle, I have come to realize that the battle for Iwo Jima may have been the hardest battle any American Soldier has ever had to endure.
That is my opinion anyway. Complete Hell on Earth facing an enemy such as these tough and determined Japanese soldiers who fought to the last man.
Thank you for your service for those Veterans who are reading this and may the fallen Rest in Peace.
