Summary The objective of this study was to investigate the rates, predictors and correlates of insomnia in a national sample of US Army soldiers. Data were gathered from the cross‐sectional survey responses of the All‐Army Study, of the Army Study to Assess Risk and Resilience in Service members. Participants were a representative sample of 21 499 US Army soldiers who responded to the All‐Army Study self‐administered questionnaire between 2011 and 2013. Insomnia was defined by selected DSM ‐5 criteria using the Brief Insomnia Questionnaire. The results highlight significant functional difficulties associated with insomnia among US soldiers, as well as insights into predictors of insomnia specific to this population. Insomnia was present in 22.76% of the sample. Predictors of insomnia status in logistic regression included greater number of current mental health disorders, less perceived open lines of communication with leadership, less unit member support and less education. Insomnia had global, negative associations with health, social functioning, support, morale, work performance and Army career intentions. The results provide the strongest evidence to‐date that insomnia is common in a military population, and is associated with a wide array of negative factors in the domains of health, military readiness and intentions to remain in military careers.
