I know a young lady who served in the green zone in Baghdad. She is beautiful and weighs 100 lbs sopping wet. The physical damage caused by her carrying 70 lbs of body armor has left her with a documented disability from the VA.
In daily PT runs women always always fall out long before men.
To think this will work in infantry is inviting defeat.
The green zone was the home of the headquarters and embassy types, not exactly infantry country. Body armor does not weigh 70 lbs.
