This study examined the frequency and characteristics of repeated attempted and completed rape (ACR) incidents reported by newly enlisted male navy personnel (N=1146) who participated in a longitudinal study during the transition from civilian to military life. Overall, 13% (n=144) reported engaging in sexual behavior that approximates legal definitions of ACR since the age of 14. Among those men, most (71%) reperpetrated ACR incidents (M = 6.36, SD = 9.55). Demographic variables were unrelated to perpetration history. Regardless of time period, respondents reported perpetrating primarily completed rather than attempted rape, perpetrating multiple ACR incidents rather than a single incident, using substances to incapacitate victims more frequently than force, and knowing their victim rather than targeting a stranger in completed rape incidents.
