the Marine Corps released research data showing that all-male teams outperformed units comprising men and women in 69% of ground-combat tasks, especially those that involve carrying heavy ammunition or weapons.
The findings, Marine officers said, show mixed-gender units are less effective in combat and more likely to suffer casualties than traditional all-male units.
In a summary of the findings, the Marines cited a 1992 presidential report that concluded: “Risking the lives of a military unit in combat to provide career opportunities or accommodate the personal desire or interest of an individual, or group of individuals, is more than bad military judgment. It is morally wrong.”
A new study in an all-volunteer unit last year confirmed the results:
The study found that in 93 of 134 tasks, all-male teams outperformed mixed-gender teams. In 39 tasks, there was no difference. In two tasks, the mixed-gender teams performed better.
“The brutal and extremely physical nature of direct ground combat, often marked by close, interpersonal violence, remains largely unchanged through centuries of warfare, despite technological advancements,” the Marines said in a summary of the research findings.
Not everyone is persuaded by the Marines approach….
