What was done
This retrospective cohort and nested case-control study analyzed administrative, personnel, and medical records of US regular Army enlisted soldiers from 2004 through 2012 to evaluate suicidal behavior among Special Operations Forces (SOF) operators, SOF support personnel, and regular Army soldiers. First nonfatal suicide attempts and suicidal ideation were identified using ICD-9 codes and Department of Defense Suicide Event Report records, and suicide deaths were identified via the Armed Forces Medical Examiner Tracking System. Sociodemographic, career, and mental health variables were adjusted in multivariable analyses.
What was found
Across 48,103,189 person-months (86.7% male; mean age 28.8 years), operator crude rates for suicide attempt were 70% lower than SOF support personnel (RR 0.3; 95% CI, 0.2-0.3) and 90% lower than the total regular force (RR 0.1; 95% CI, 0.1-0.2). Operator crude rates for suicidal ideation were 70% lower than support personnel (RR 0.3; 95% CI, 0.2-0.3) and 80% lower than the regular force (RR 0.2; 95% CI, 0.1-0.2), while suicide death rates did not differ between groups. The ratio of suicide attempts to suicide deaths was 2.1 (95% CI, 1.9-2.3) for operators, 7.6 (95% CI, 7.5-7.7) for support personnel, and 15.0 (95% CI, 15.0-15.0) for the total regular force. Adjusting for sociodemographic and career factors attenuated but did not eliminate operators' lower risk. Lower rank, past-year demotion, and mental health diagnoses were associated with attempts in both SOF groups. Odds of suicide attempt were higher for female operators (OR 7.4; 95% CI, 3.2-17.1), whereas sex was not associated with attempts among support personnel.
Why it matters
Although SOF operators exhibit lower overall rates of suicidal ideation and nonfatal attempts than other military groups, their suicidal behaviors have much higher case fatality. Suicide prevention strategies in elite units must account for this heightened lethality and address elevated risk in subgroups like female operators.
Limits
The study relies on retrospective administrative and medical coding, which inherently misses unreported ideation and nonfatal attempts. Findings are restricted to enlisted soldiers on active duty between 2004 and 2012 and do not cover officers or post-separation outcomes. The total count of distinct individuals is not reported in the abstract, and the small number of female operators resulted in wide confidence intervals.
