Research shows that military service is linked with political engagement, such as voting. This connection is strongest for minorities. The authors explore the relationship between military service and volunteering. They conclude that military service helps overcome barriers to volunteering by socializing people with civic responsibility norms, by providing social resources and skills that compensate for the lack of personal resources, and by making veterans aware of opportunities to volunteer as well as asking them to do so. Military service is positively related to volunteering among blacks and Hispanics. Married veterans are more likely to volunteer than nonveterans. Veterans who served during wartime are more likely to volunteer than those who served in peacetime.
