Additionally, the film adaptation changes some characters' names and omits certain other characters, i.e.: several "lifers" (Captain January, Major Lynch, and General Motors) have been left out or have been merged into one character; Private Leonard Pratt in the book is renamed Leonard Lawrence in the movie; Gunnery Sergeant Gerheim in the book is renamed Hartman in the movie; and the character of Alice in the book seems to have been renamed and altered slightly to portray Eightball in the movie. In additional divergences from the book, in the film T.H.E. Rock does not die, and Crazy Earl is killed by a booby trap. The book characters Daytona Dave, Chili Vendor, and Mr. Payback appear in the movie, just prior to and during the Tet Offensive, but in the book Daytona Dave is described as a California surfer-type, while in the movie he is played by an African American.
