^a Deceased soldiers represent those who died within 18 months of separating from service.

^b Missing observations for deceased soldiers: age (n = 5), time in service (n = 17), and character of service (n = 168). Time in service for the deceased soldiers does not include those with less than 1 month of service.

^c Other includes under other than honorable, bad conduct, and dishonorable-dismissal.

^d Ninety-seven percent of unknown discharge types were Guard and Reserve.

^e Legal intervention includes injuries inflicted by the police or other law-enforcing agents, including military on duty, in the course of arresting or attempting to arrest lawbreakers, suppressing disturbances, maintaining order, and other legal actions, and excludes injuries caused by civil insurrections. Operation of war includes injuries to military personnel or civilians caused by war or civil insurrection, including those occurring during the time of war or insurrection and after cessation of hostilities. The number of deaths in this category (i.e., ICD-9 codes E990-E999 for 1981 through 1998 and ICD-10 codes Y36.0-0.9 for 1999 to present) is small (e.g., 14 in 2003). These operation of war deaths are included in total but cannot be reported separately using the Web-based Injury Statistics Query and Reporting System (WISQARS).²¹
