We exploit plausibly exogenous variation in overseas deployment assignment to estimate the effect of combat exposure on psychological well-being. Controlling for pre-deployment mental health, we find that active-duty soldiers deployed to combat zones are more likely to suffer from post-traumatic stress disorder (PTSD) than their counterparts deployed outside the United States in non-combat zone...

For multimulti-unmanned aerial vehicle (UAV) air combat decision problems, this paper proposes a multi-UAV task allocation method based on cloud model. Firstly, we analyses air combat situation advantage of random and fuzzy information. The cloud model is applied to multi-UAV task allocation. We establish air combat superiority index model based on cloud model. And then through comprehensive cl...

Research suggests that combat exposure might increase risk for suicide. The interpersonal-psychological theory of suicide (IPTS) proposes that exposure to painful and provocative experiences such as combat contribute to fearlessness about death and increased pain tolerance, which serve to enhance the individual's capability to attempt suicide. Violent and aggressive combat experiences, in parti...

This study used quantitative volumetric magnetic resonance imaging techniques to explore the neuroanatomic correlates of chronic, combat-related posttraumatic stress disorder (PTSD) in seven Vietnam veterans with PTSD compared with seven nonPTSD combat veterans and eight normal nonveterans. Both left and right hippocampi were significantly smaller in the PTSD subjects compared to the Combat Con...

As the Services move to transform joint and coalition operations, a new capability being contemplated for the transformed forces is synchronizing manned-combat-vehicle and unmanned-combat-vehicle target engagements. However, we are just beginning to work out the details for implementing such a symphony of coordinated human and machine decisions and actions. One challenge in realizing an impleme...

While Lanchester’s equations are commonly used as the basis for force-on-force combat models, it is important to remember that Lanchester’s Equations are not a model of combat, only a model for combat attrition. There have been numerous attempts to compare historical combat data with the behaviour expected from Lanchester's Equations. The present work extends this comparison between historical ...

This is the first longitudinal cohort study of Persian Gulf War US soldiers to examine belief in exposure to chemical and biological weapons before and shortly after combat. A longitudinal sample of n = 1250 male Persian Gulf War US Army soldiers were surveyed 3 to 4 months before and 6 to 10 months after the 1991 War. Six to 10 months after combat, 4.6% of the cohort believed they had been exp...
