"Lift your head and hold it high! Mighty Mike is passing by!" So sang the 250 diverse soldiers of M Company ("Mighty Mike") as they went marching to Vietnam. Their right feet hitting the snow simultaneously, they sang, "Am I right or wrong?" They had their answer three weeks later. "Great reportage," The New York Times. "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. "Absolutely the best book to come out of Vietnam," The Cleveland Press. M has been nominated by the NYU Department of Journalism as one of the top journalistic works of the twentieth century.
