Can the general population of fighting-age American women be expected to perform equally with their male counterparts? According to a U.S. Army Soldier Systems Center study released in 2004, the average fighting load carried by an infantry rifleman operating in Afghanistan was 63 pounds before adding a rucksack. The average approach-march load in combat, which includes a light rucksack, was 96 pounds. The average emergency-approach-march load, which includes a larger rucksack, was 127 pounds.

Would the infantry have performed as well in past wars had half the billets been filled by women instead of men?

Can fighting-age American women be counted upon to fulfill their duties without causing an increased administrative burden in time of national emergency? Around the time my company received orders to deploy to Afghanistan in 2002, a number of women in my unit became pregnant. My company, stationed at Fort Bragg, N.C., attached soldiers from two other Army posts to fill the vacancies caused by the inability of these female service members to deploy.

Will women serving in the infantry be injured more frequently or more seriously? In a 2011 article, the Seattle Times estimated the Department of Veterans Affairs paid over $500 million in benefits annually for degenerative arthritis, cervical strains and other musculoskeletal injuries. Will disability payouts increase with women serving in the infantry? I believe the defense leadership must conduct an objective study of basic training and military-school injury rates by gender to more accurately predict answers to such questions.
