Marine Corps Deployment Tempo and Retention from FY04 through FY07
Published Date: October 1, 2008
The Global War on Terror has become the Long War, and the increase in operational tempo that enlisted Marines and Marine officers have experienced since 9/11 is expected to continue. Although the Corps exceeded its aggressive FY07 endstrength goal, we continue to monitor the relationship between deployment tempo and retention. We analyze how deployment tempo, measured by deployed days and number of deployments, influences reenlistment and retention. We look at the reenlistment decisions of enlisted Marines between FY04 and FY07 and the retention decisions of Marine officers between December 2006 and December 2007. We find that additional deployments to the Iraq/Afghanistan country groups decreased first-term reenlistments during the FY04-FY07 period. Focusing just on FY07, we find that additional deployments to the Iraq/Afghanistan country groups are predicted to increase reenlistment for Marines with dependents and decrease reenlistments for Marines without dependents. For FY04-FY07 and just FY07, we find that an additional 100 days deployed in non-crisis areas has no statistically significant effect on reenlistments for first-term Marines with dependents but decreases reenlistments for Marines without dependents. Among career Marines and Marine officers, we find that additional deployed days have either no effect or a small positive effect on retention.
