The US Marines tested all-male squads against mixed-gender ones, and the results were pretty...

The Marine Corps did as fair a job on these as could be done. I read the study when it came out. Because it did not push the women in combat mantra it was ignored and buried by the Obama administration. If you need a study to demonstrate the folly of integrating women into combat arms roles you are not paying attention do the world around you.

And yet, 'they' continue to strive for more female participation in Assault Infantry and Infantry Heavy Weapons MOSs'.
