Marine Corps Separation Rates: What's Happened Since FY 00
October 1, 2008
As the Marine Corps continues its growth toward an active-duty endstrength of 202,000, it needs to reduce the rate of separations (including end-of-active-service (EAS) and non-EAS separations) for enlisted Marines and officers. In this document, we examine separation rates over the FY00 to FY07 period and assess their patterns. We find that, despite high operational tempo, average separation rates for enlisted personnel, warrant officers, and commissioned officers were actually lower in FY07 than in FY00. There were, however, small increases in separation rates for some subgroups, including females, retirement-eligible aviators, and ground officers with 7 to 10 years of completed service. Still, the overall pattern of separation rates indicates no worrisome trend.

The Effect of Deployment Tempo on Marine Corps Selected Reserve Retention
July 1, 2007
Since September 11th, 2001, the Marine Corps has involuntarily activated considerable numbers of the Selected Marine Corps Reserve (SMCR) to support Operation Noble Eagle (ONE), Operation Enduring Freedom (OEF), and Operation Iraqi Freedom (OIF). This presidential mobilization of the Reserves represents the longest period of involutary activations since the formation of the All-Volunteer Force. In this paper, we examine how this increase in operational tempo has affected the composition of and retention in the SMCR. We take two approaches in our analysis. First, we use descriptive statistics to understand changes in the SMCR between September 2001 and September 2006. Second, we use survival analysis to determine the effect of activation on a reservist’s decision to stay affiliated with the SMCR.
