Gray, Mora and five other soldiers died Monday when their truck overturned near the Iraqi capital, U.S. officials said.
Gray and Mora were among seven soldiers, mostly sergeants, who wrote the op-ed piece that appeared in the Times on August 19. It called the prospects of U.S. success "far-fetched" and said the progress being reported was being "offset by failures elsewhere."
"Four years into our occupation, we have failed on every promise, while we have substituted Baath Party tyranny with a tyranny of Islamist, militia and criminal violence," they wrote. "When the primary preoccupation of average Iraqis is when and how they are likely to be killed, we can hardly feel smug as we hand out care packages."
