In reply to your question:- What I am trying to say is that not only are the women in the combat zones exposed to the same risks as their fellow male soldiers,they are also exposed to other risks as well,especially that of sexual assault from not only those termed the enemy,but also from those with whom they serve.Additionally,they lack upper body strength,which in turn increases risks to themselves and others fighting with them.
The 30% stat comes from memory,however the first article I googled came up with exactly that,and a lot more that supports my point of view on the subject.
