TL;DR: In this paper, the authors studied the mental health of four U.S. combat infantry units (three Army units and one Marine Corps unit) using an anonymous survey that was administered to the subjects either before their deployment to Iraq (n=2530) or three to four months after their return from combat duty in Iraq or Afghanistan (n =3671).

TL;DR: The findings indicate that among the study groups there was a significant risk of mental health problems and that the subjects reported important barriers to receiving mental health services, particularly the perception of stigma among those most in need of such care.

TL;DR: Specific combat experiences, including greater exposure to violent combat, killing another person, and contact with high levels of human trauma, were predictive of greater risk-taking propensity after homecoming, highlighting the importance of education and counseling for returning service members to mitigate the public health consequences of elevated risk-propensity associated with combat exposure.

TL;DR: This article used evolutionary game theory to model how the host country cultural environment places selective pressure on the cultures of immigrant populations, and found that the lower the cost of coordination for allocentric immigrants, the easier it becomes for both allocentric and idiocentric immigrants to assimilate into collectivist societies.
