Those images are awesome!! Everyone should go take a look.
If you like those, definitely check out the book I mentioned in a previous post, Requiem: By the Photographers Who Died in Vietnam and Indochina
You might also be interested in Larry Burrows: Vietnam, _Don_McCullin_ by Don Mccullin (out of print?), and Inferno by James Nachtwey.
These books are large, expensive, coffee table type books. You can probably find them at your local library or get them through an interlibrary loan.
That said, I must warn you that many of the pictures are incredibly graphic and are not for a weak stomach. The pictures on DOD websites have been censored. These have not and show war in its full horror.
