ABSTRACT
One radical strand of the post-Clausewitzian unconventional school of military theory is that of American Fourth Generation Warfare that dates from the late 1980s and which has made intermittent appearances in professional military journals over the last fifteen years.3 Leading advocates of the Fourth Generation school include the maneuver warfare theorist, William S. Lind and a number of US Marine Corps officers – including the author whose essay is the subject of this symposium – Thomas X. Hammes.4
