“…We contribute to a growing body of literature that has examined the effects of combat deployments on a number of medium‐term and long‐term outcomes including violence, health, homelessness, family structure, and education (Ackerman, Porter, & Sullivan 2020; Armey & Lipow 2016; Cesur, Chesney, & Sabia 2016; Cesur & Sabia 2016; Cesur, Sabia, & Tekin 2013, 2015; Engel, Gallagher, & Lyle 2010; Lyle 2006; Negrusa, Negrusa, & Hosek 2014; Shen, Cunha, & Williams 2016). Consistent with the previous literature, we use the exogeneity of combat deployments to estimate the effect of combat deployments to Iraq or Afghanistan on casualty rates (see Lyle [2006] for elaboration).…”
