Some reviewers have suggested that Heinlein was simply discussing the merits of a selective versus a nonselective franchise. Heinlein made a similar claim, over two decades after "Starship Troopers"'s publication, in his "Expanded Universe" and further claimed that 95 percent of "veterans" were not military personnel but members of the civil service. Heinlein's own description has been disputed, even among the book's defenders. Heinlein scholar James Gifford has argued that a number of quotes within the novel suggest that the characters within the book assume that the Federal Service is largely military. For instance, when Rico tells his father that he is interested in Federal Service, his father immediately explains his belief that Federal Service is a bad idea because there is no war in progress, indicating that he sees Federal Service as military in nature. Gifford states that although Heinlein's intentions may have been that Federal Service be 95 percent non-military, in relation to the actual contents of the book, Heinlein "is wrong on this point. Flatly so."
