One of the best sources of photos of all aspects of military life in WWII was LIFE magazine.
Google has now scanned two million of the 10 million photos in the LIFE archives and placed them online. You can also type in a keyword in the Google search box and then follow it with the phrase source:life - so if you wanted to see images of Patton you'd type in Patton source:life - when the results come up click the Google IMAGES button.
Here's showing the results when I used the search term Iwo Jima source:life http://images.google...G=Search Images
The life photos are outstanding and it is quite fun actually to just keep plugging in different keywords before the source:life phrase.
Thank you so much for posting this!!!!!!!!!!!!!!!!!! I know I"m going to spend a lot (and I do mean a LOT) of time with this, I've loved reading about WW2 ever since I was a kid. THANKS again.
