What is the theme in Bloods: An Oral History of the Vietnam War by Black Veterans by Wallace Terry?

Skin color is another theme in this story. Blacks are not accepted by white soldiers in the military simply because of the color of their skin. When Edgar Huff joins the Marines he is thrown in jail for impersonating an officer because a group of white men do not believe that the Corps admitted a black man. Some of the white soldiers view the black men in their company as the enemy just as if they were Viet Cong. Black soldiers are subjected to racism both overt and subtle by white soldiers, officers and the American government.
