The suicide rate of active-duty soldiers doubled between 2003 and 2010. In response, the Department of Defense and the United States Army improved their data collection methods to better understand the causes of military suicides. As retired colonel Dr. Elspeth Cameron Ritchie writes, unit history and the accumulation of stressors-from relationship problems to chronic pain-are significant suici...

Defense against enemies is a type of natural selection considered fundamentally equivalent between the sexes. In reality, however, whether males and females differ in defense strategy is unknown. Multiparasitism necessarily leads to the problem of defense for a parasite (parasitoid). The polyembryonic parasitic wasp Copidosoma floridanum is famous for its larval soldiers' ability to kill other ...

The mental health (MH) of soldiers remains extremely newsworthy and is regularly featured in high profile media forums that focus on post-traumatic stress disorder. However, the authors feel that there are distinct benefits to serving within the Army, and that it provides effective occupational medical, MH and welfare support. This research study explores potential benefits and stressors of bei...

OBJECTIVE Recent surveillance data suggests the United States (U.S.) Army HIV epidemic is concentrated among men who have sex with men. To identify potential targets for HIV prevention strategies, the relationship between demographic and clinical factors and membership within transmission clusters based on baseline pol sequences of HIV-infected Soldiers from 2001 through 2012 were analyzed. M...

Since 2003, about 14 % of U.S. Army soldiers have reported symptoms of posttraumatic stress disorder (PTSD) following deployments. In this article, we examine how post-deployment symptoms of PTSD and of other mental health conditions are related to the probability of divorce among married active-duty U.S. Army soldiers. For this purpose, we combine Army administrative individual-level longitudi...

The Soldier Information Requirements Technology Demonstration (SIREQ TD) project is an experimentation program to identify technologies that significantly enhance the performance of our future soldiers. One of the study series involved a 2 x 2 factorial comparison of the benefits of digital maps over paper maps, and the use of radios vs. no radios. Thirty-two Canadian regular force infantry sol...

BACKGROUND Suicidal ideation is a risk factor for suicide attempt. The aim of the present study is to compare suicidal ideation of different groups with different distress. METHODS 100 soldiers, aged 18-21, divided into four research cohorts: soldiers who had carried out a suicide attempt (n = 40); soldiers with a psychiatric diagnosis (n = 20); soldiers having high severity adjustment diffic...

The principle of discrimination (or distinction, as it is sometimes called in legal circles) requires that soldiers treat civilians differently from fellow soldiers, generally not attacking the former except in extreme situations. The Geneva Conventions call for a clear separation of people into two camps: those who are protected from assault, including army medical personnel, injured soldiers,...
