We are indebted to General Westmoreland. General Abrams and many other distinguished and extinguished personnel of the United States Armed Forces and the New Zealand Armed Forces for the information contained in this feature. Understanding, as we do, that many useful and peaceful applications of technology have been developed, and sometimes originated by the armed forces, we present this information to students as part of their general educational experience. It is, of course, neither practicable nor sensible that one should have any more than an esoteric and purely theoretical understanding of these aspects of military science. It is supposed that some reading in the martial arts will broaden the students' understanding of the duties, responsibilities and difficulties that the military experience as almost uniquely their own problem. Hopefully students may perhaps then become a little more tolerant of the armed forces and understand the reasons for their existance, even if remaining reluctant to concede them a status better than a "necessary evil".
