"This chronology is designed to encompass major anti-U.S. incidents that occurred in 1992. Unfortunately, to keep this publication at the unclassified level, some incidents had to be omitted due to the sensitive nature of the information associated with them. The selection of incidents used in this study was based upon the following criteria: lethality, substantial, property damage, use of unusual tactics or weapons, and perceptibility of targets as U.S. or representative of U.S. interests."
