"Great literature," The Dallas Morning News . "A superb book," The Nation . "One must go back to Orwell for appropriate comparisons," The Washington Post . "Sack achieves the quality of William March's Company K in World War I, of James Jones' From Here to Eternity in World War II," The Los Angeles Times .
