If we use ‘gender-blind’ recruitment and training, some women will be able to meet the required standards, but most will not. The small number of suitable female candidates set against the additional logistical, regulatory and disciplinary costs associated with integrating them, mean that integration is not worthwhile.  For example, one test of American army officer candidates showed that "only one woman out of 100 could meet a physical standard achieved by 60 out of 100 men” [1]  Some roles such as those of sniper and combat aviator clearly require less physical strength than most active combat roles. Many tasks that combat soldiers must accomplish require high muscle density, which women do not naturally possess. [2] Examples would include carrying a wounded soldier, throwing grenades or digging a trench in hard terrain.  Older and more senior soldiers make up for their reduced physical strength with an increased amount of experience. The same cannot be said for new female recruits.
