Military demonstrations could conveniently be classified according to objective under two major headings: (a) those intended primarily to convey purpose or intention, and (b) those intended primarily to convey capability. The latter type is generally free of the political risks which often attend the former. Both types, but especially the former, may be effected without necessarily disclosing new advances in the use, design, or performance of weapons. In the latter type, however, there may be a strong temptation—or a strong justification even in the absence of temptation—to parade a new or improved weapon or weapons system which reflects both technological achievement and enhanced capability.
