This theoretical treatise uses the scientific literature concerning help seeking for mental illness among those with a background in the U.S. military to posit a more complex definition of military culture. The help-seeking literature is used to illustrate how hegemonic masculinity, when situated in the military field, informs the decision to seek formal treatment for mental illness among those men with a background in the U.S. military. These analyses advocate for a nuanced, multidimensional, and situated definition of U.S. military culture that emphasizes the way in which institutional structures and social relations of power intersect with individual values, beliefs, and motivations to inform and structure health-related practices.
