There is a relatively higher female Injury rate  If militaries use gender-blind recruitment and training, women will suffer a high rate of injury as a result of physical differences. The standards of physical fitness have been set to suit men, and women attempting to reach them will over-stretch themselves. For example, when the U.K. military began using gender-blind training in the 1990s, the rate of medical discharge of female recruits jumped from 4.6% to 11.1%. [1]  In addition, regardless of recruitment and training standards, combat units engage in activities designed to suit men’s capabilities. Women serving in integrated units will suffer higher injury rates as a result of this. For example, armies march according to the male stride length of 45 cm, rather than the shorter female stride length of 38 cm. Women marching at the male pace are therefore at increased risk of stress fractures in pubic bones. [2]  [1] Gemmell, Ian M.
