How does Seymour Hersh use imagery in Chain of Command: The Road from 9/11 to Abu Ghraib?

Example of Imagery:

"We've got this large conventional force sitting there and getting their ass shot off, and what we're doing is counterproductive. We're sending mixed signals. We've got no intelligence, and we're too squeamish to operate in this part of the world." Chapter 6, pg. 275
