Seriously, folks, it's a desert. 50 guys getting heavily blasted and plowed over by M1A1s and Bradleys aren't going to leave enough to fit in a Ziploc bag. The sand can easily cover what's left over.
Now, I agree that it is kind of amatuerish to make a claim like that to the press. We haven't been giving out enemy casualty information thus far, even when we had the bodies.
