In the spirit of Ambrose Bierce, "A Grunt Speaks" is more than a simple glossary of the terms used by infantrymen during the Vietnam conflict. The terms are defined both by their formal meaning but also by how infantrymen perceived them, both the theory and the practice. Also, the author shares the experiences of the infantry with these concepts on the battlefield, in the basecamps, and at home. "A Grunt Speaks" is a memorial to the sacrifices, heroism and tragedies of infantryman who fought the Vietnam war.
